# The Effects of Abandonment Options on Investment Timing and Profit Sharing of FDI

**Academic Editor:**Paolo Renna

#### Abstract

The paper incorporates cooperative game theory into a real option method in a foreign direct investment setting and examines the operational decisions of a multinational corporation in a cooperative framework, where the corporation is endowed with an abandonment option and shares its profit with the host country. In particular, we investigate how the abandonment options affect the optimal investment timing and the optimal profit share of a foreign direct investment using a real option game method. We show that the flexibility of the abandonment option induces the corporation to investment earlier, which indicates the negative effects on investment trigger. The result is consistent with intuition since the abandonment option provides insurance and thus reduces the overall risk of the project. We also find that the introduction of the abandonment option reduces the optimal profit share in a cooperative framework and in turn the lower profit share increases the investment trigger, thereby having a positive effect on the investment threshold to hinder the investment. By numerical analysis, we find that the overall effect of the abandonment options is inversely related to the investment trigger. These findings provide quantitative analysis about the decisions regarding cooperation in international investment extraction projects.

#### 1. Introduction

The globalization trend of foreign direct investment is increasingly strengthening and foreign direct investment has been experiencing rapid growth in recent years. According to the latest world investment report of the United Nations, the output value of multinational corporations and their parent companies accounts for nearly a quarter of global GDP [1–4]. In addition, a foreign direct investment involves large capital budgets, long construction periods, and high uncertainties, which include the fluctuation of international exchanges, the changes of product price, and the modification of national investment policy. When the investment encounters adverse conditions, then the divestment will occur [5–10].

Previous studies have extensively examined the investment timing decisions for foreign direct investment, thus providing decision-making information [11–21]. However, very few works consider the impacts of abandonment options on optimal investment decisions and profit sharing in cooperative games, especially in foreign direct investment. Moreover, it is common for multinational corporations (hereafter, MNC) to divest from the host country (hereafter, HC) in light of the fiercely competitive environment and recent changes with regard to the MNC’s strategies [6, 22–24]. For instance, the withdrawal of Honda from Formula One in 2008 (Financial Times, 2008) reflects global financial distress and economic crisis in the auto industry. In addition, according to the data from the Ministry of Commerce of China, 4564 MNCs left the host country market from January to November in 2008 (http://www.mofcom.gov.cn/). Consequently, it is critical to investigate the effect of abandonment options on the investment behaviors of MNCs in foreign direct investment, explore theoretic aspects concerning the economic significance of abandonment, and give quantitative analysis about the degree of impact, which in turn provides managerial insights and suggestions for HC to make foreign investment policies.

In early research about the abandonment option, after the seminal work by Robichek and Van Horne [25], more and more literature has been concerned with abandonment options in capital budget and investment decisions. Myers and Majd [26] view the option to exit as an American put option with dividends, calculate the value of the abandonment option, and study the economic significance by using numerical analysis. McDonald and Siegel [27] examine a firm’s investment decision, assuming that the firm can shut down production if variable costs exceed the net profits. Several papers investigate the abandonment decision on the natural resource investments. Based on the option pricing method, Brennan and Schwartz [28] evaluate the value of irreversible natural resources and provide suggestions on a coal mine’s investment and abandonment decisions. Lain [29] examines the exit and expansion timing and indicates that it is optimal to delay investment or abandon the oil project when the prospects seemed to be bad and it is profitable to exercise the option to expand when the prospects are better. Further, from the perspective of corporate behavior and decision-making, Tsekrekos [30] studies a firm’s optimal entry and exit decisions in the face of uncertainties about future profits and construction periods. Wong [31] investigates the behavior of a competitive firm when the firm has an abandonment option and has an access to a forward market under output price volatility. When the marginal cost is higher than the output price, it is optimal for the firm to exercise the option to exit and cease production. Wong [32] examines how the presence of an abandonment option affects a firm’s investment decisions, especially the operating leverage. The results show that the firm will reduce operating leverage in the presence of an abandonment option, thereby making the firm more reluctant to invest in the project.

The purpose of the paper is to investigate the effects of abandonment options on investment timing and profit share in a cooperative game, combine real options with the bargaining game, and drive the investment timing of FDI and the optimal profit share between HC and MNC.

The most correlated literatures to our study are Brandão de Brito and de Mello Sampayo [19] and Di Corato [33], which also examine the investment decisions of a foreign direct investment in a real option framework. In Brandão de Brito and de Mello Sampayo [19], the firm’s profit, which is determined by the attractiveness, follows a Brownian motion and the timing of foreign direct investment is delayed with the increase of uncertainty of attractiveness. Results from the model calibration support the model analysis. While Brandão de Brito and de Mello Sampayo [19] only provide an optimal rule for entry, the paper does not study the exit decisions of foreign direct investment. The work is also closely related to Di Corato [33], which only studies the investment decisions of MNC under the threat of nationalization and ignores the effects of an abandonment option on investment timing in cooperative games.

Our article incorporates cooperative game theory into the investment problem of foreign direct investment in a cooperative game using real options game model. In the model, MNC is endowed with the abandonment option after investment and cooperates with HC to extract natural resources and share the net project profit. During the investment process, MNC may be faced with the risk of asset expropriation by HC without any compensation and the loss of suck costs [33–36]. Therefore, MNC will divest at any time from HC if the project faces an adverse investment environment. The divestment decision of MNC from HC has a negative effect on employment and economic growth. Thus, HC should predict the investing behaviors of MNC with exit flexibility in cooperative game and further promote better cooperation with MNC by taking favorable policies. When MNC abandons the project, HC will pay for the salvage value of the project and take it over from MNC after the abandonment to promote national economic growth. Moreover, the option to completely or partially abandon a project has been widely used in practical application. For example, if the natural gas or oil price is volatile, producers will decide to expand or contract or even shut down production [28–30].

In particular, we explore the optimal investment timing of foreign direct investment with and without the abandonment option in real options game model, respectively, and investigate the effect of the abandonment options on investment trigger. We also examine the optimal profit share of HC and MNC by using Nash Bargaining Solutions in a cooperative framework in two cases and obtain main three interesting results.

The first one is that if the investment project is partially reversible, the optimal investment trigger of MNC with an abandonment option is smaller than that without. That is, the flexibility of the abandonment option induces the multinational corporation to investment earlier, which indicates the negative effects on investment trigger. So, MNC with an abandonment option has the incentive to invest in the project earlier than without. When MNC holds an option of abandonment and the project is completely irreversible, which indicates that the project has no salvage value, then two optimal investment thresholds in two cases are the same regardless of the abandonment option. The results show that the abandonment option pulls down the investment threshold.

The second is that the introduction of the abandonment option reduces the optimal profit share in a cooperative framework and in turn the lower profit share increases the investment trigger, thereby having a negative effect on the investment threshold if the multinational corporation is more risk averse. That is, the optimal profit share of MNC with the abandonment option is lower than that without, if the relative risk aversion is greater than some critical value. Moreover, the profit share is inversely related to the investment trigger. The results show that MNC with more risk aversion has considered the influences of the option to exit on the management flexibility, and HC gives up part of its profits from the project to induce MNC to invest in the absence of an abandonment option. Therefore, the optimal share is analytically determined in the bargaining process, depending on whether the project has an abandonment option or not.

Finally, we conclude that the two investment timing triggers decrease with the profit share and the abandonment option has two opposite effects on the investment in general, which is the positive effect, thereby pulling down the investment trigger and the other is the negative effect by increasing the critical investment value. By numerical analysis, we find that the overall effect of the abandonment options is inversely related to the investment trigger. The results indicate that the influences of the profit sharing ratio on the investment behavior dominate the influences of the abandonment options and MNC pays more attention to the profit sharing ratio.

The remainder of this paper is organized as follows. The model is presented in Section 2, and Section 3 derives the exit decision of MNC. Section 4 studies the investment decision of MNC in two cases: where the abandonment option is present or not in a cooperative framework. We also compare the investment trigger of MNC with the abandonment option of that without. We determine the optimal profit sharing ratio between MNC and HC and show that the optimal profit share without the abandonment option is always larger than that with it if the multinational corporation is more risk averse in Section 5. Section 6 conducts numerical analysis to access the solutions of the model and shows that the overall effect of the abandonment options is inversely related to the investment trigger. Finally, conclusions and topics for further research are presented in Section 7.

#### 2. The Model

In the model, we assume that MNC and HC sign an agreement on engaging in the extraction of natural resources in the model. HC is finance-constrained and cannot pay for the total extraction cost of the project, while MNC can undertake investment cost , where . Therefore, in order to encourage investment, promote economic growth, and improve the welfare of HC, both parties make the following agreement on extraction of the natural resource: HC provides access to the extraction project and MNC undertakes the initial investment cost and extracts the natural resource in an infinite term. After completion of the project, both parties share each unit of profit, respectively, to MNC and to HC, where . Due to the uncertainty of the national economic environment, market conditions, and the price of the extracted resource, MNC has the option of abandonment the project in the face of great price fluctuations.

When MNC decides to abandon the project, HC will pay the salvage value of the project to MNC and take over the project, where denotes the recovery rate of investment cost . Similar to Wong [32], this indicates that the project is completely irreversible and has no salvage value if . That is, MNC cannot get any profit when MNC shuts down the production. If , the project is totally reversible, so that the salvage value of the project can recover investment cost. Consistent with the real context, MNC holds an option to invest in the extraction project and has an abandonment option when the profit flow is lower than a certain trigger in the model.

For the sake of simplicity, we assume that the operating cost, which is generally supposed to be constant in most models, is zero [32, 33, 37]. If the investment option is exercised at time , MNC incurs the initial cost , and the stochastic net profit flow per unit time of the project, , is governed by the following geometric Brownian motion:where and are the instantaneous drift and volatility and denotes the wiener process with and . We assume that MNC and HC are risk-neutral and the risk-free rate is a constant . For convergence, we also assume that .

In order to investigate the effects of the abandonment option and profit share ratio on the investment timing of FDI, the model solves decision problems of MNC by using backward induction. First, as a bench mark, we derive the optimal exit and investment decisions of MNC without the option of abandonment. And, then, we compare the results to those in which MNC has the abandonment options. Finally, we determine the profit share ratio for both parties according to whether MNC possesses the option of abandonment or not.

#### 3. Optimal Exit Decisions from the Extractive Project

In this section, we derive the postinvestment extractive project value before exercising the abandonment option and deduce the optimal exit decision by maximizing the profit of MNC.

After investment, MNC holds an option of abandonment. The abandonment option can be viewed as a perpetual American put option with an exercise price equal to the salvage value of project , and the underlying asset is the sequence profit flow of the project. After investment, the project produces net profit flow at time , . According to the agreement on the distribution of project profit, MNC acquires the net profit flow at time , , and HC gets net profit flow at time , .

Let be the random first passage time for the state variable to reach from above. We refer to as the abandonment trigger, and the subscript denotes exit. That is, when the profit flow at time , , is lower than the abandonment trigger, , MNC exercises the option to exit. The abandonment trigger, , is endogenously determined by the model by maximizing the value of abandonment option.

So, prior to abandonment, the expected net present value of MNC after investment is given by

Similarly, HC’s expected net present value iswhere denotes the expected operator given that . Equation (2) indicates that the expected net present value of the project for MNC is the profit share value of the project plus the salvage value of the project when MNC shuts down the production at the abandonment instant . Equation (3) reveals that HC’s expected net present value is equal to the profit share of the project plus the net present value of sequent profit flow, when the project is owned by HC.

Applying Ito’s lemma, the value of active MNC, , satisfies the following ordinary differential equation (ODE):Following the same procedure as Dixit and Pindyck [38] and Lucas and Prescott [39], the general solution of ODE (4) is given bywhere is an endogenous constant and The constant and the abandonment trigger can be solely determined by the following value-matching and smooth-pasting conditions:Condition (7) expresses the fact that the perceived value of MNC at the abandonment instant is equal to the salvage value of the project . Condition (8) requires that the abandonment trigger should be chosen to maximize the perceived value of MNC.

Under these conditions, and are solved as follows:Note that the abandonment trigger decreases as the profit share increases. The result implies that the decrease in the abandonment threshold induces MNC to delay exiting the project.

Substituting (9) and (10) into (5) yields the value of MNC, , in the following form:The first term of the first line of (11) represents the perpetual payment if MNC does not abandon the project, and the second term is the value of the abandonment option. On the second line, MNC gets the salvage value of project by exercising the option of abandonment.

Similarly, the value of HC, , must satisfy the following ordinary differential equation:The general solution to (12) is given bywhere the constant can be solely determined by the boundary conditions.

HC gets the ownership of the extraction project while MNC is sold the salvage value of project at the abandonment instant . Therefore, the value of HC at the abandonment instant is Combining with the above conditions, the value of HC, , can be given by According to the continuity condition, we obtain Combining (15) with (16), we can get the explicit solution of .

#### 4. Optimal Investment Timing of the Extractive Project

Next, the optimal investment decision is endogenously determined by the model. When the profit flow is sufficiently high or above a certain trigger, MNC will invest in the project immediately by incurring the initial investment cost. Therefore, we know that the optimal rule to exercise the option to invest is equivalent to finding a sufficiently high threshold . It is optimal for MNC to exercise the option to invest when the state variable is the stochastic first passage time for the process from below. We refer to as the investment trigger. Let be the random first passage time for the state variable to reach , from below. Next, we examine two different cases: the case without the abandonment option and the case with the option of abandonment. In what follows, we first outline the solutions for the two scenarios and then the results.

##### 4.1. Optimal Investment Decisions without the Option of Abandonment

As a benchmark, we first consider the investment decision in the absence of the abandonment option. When the abandonment option is prohibited, the profit distribution ratio of MNC is and HC’s profit share is .

If abandonment is prohibited, MNC will perpetually run the extractive project. Therefore, when the project is undertaken, the expected net profit value of MNC, , can be represented as follows:In the continuation region , the ordinary differential equation for the value of MNC is given byThe general solution of (18) can be expressed asAccording to the value-matching and smooth-pasting conditionsWe can solve the investment trigger and the constant in the following forms:

Note that the optimal investment trigger of MNC without abandonment is negatively related to the distribution of profits . We can see that the greater the profit share is, the smaller the investment trigger is, which indicates that MNC should invest earlier. As a result, to induce MNC to hasten investment, HC should increase the profit share to compensate for the investment loss of MNC in cases of lower profit flow.

To sum up, then, the value of MNC is expressed asAccordingly, the value of HC can be expressed as

##### 4.2. Optimal Investment Decisions with the Option of Abandonment

In this section, we assume that MNC holds an option of abandonment and possesses the profit share of the project as long as the firm invests in the extraction project. Therefore, MNC must decide when to invest at the presence of the abandonment option. We also assume that the net profit value of MNC is and the abandonment trigger satisfies the inequality ; otherwise, no firm will invest in the project forever.

When the investment threshold satisfies the inequality , the value of MNC at can be given bywhere the first term on the right-hand side of (25) is the profit value of MNC without the abandonment option, and the second term is the value of the option of abandonment at .

The expression shows the abandonment option is positive. If , the profit value of MNC, , can be expressed as In the continuation region , the profit value of MNC can be given byAccording to the boundary conditions

We solve implicitly the investment trigger, which satisfies the following equation:From (29), we see that MNC decides the investment timing to maximize the perceived net profit. Equation (30) is a nonlinear equation with no known analytical solution. Hence, the investment trigger can be obtained numerically. The result in (30) demonstrates that the investment trigger depends on the profit share , the abandonment threshold , and the recovery rate .

To sum up, we rewrite the value of MNC:Similarly, the perceived profit value of HC at can be expressed asTherefore, the value of HC is given by

##### 4.3. Comparative Analysis about Two Investments Triggers in Two Cases

Proposition 1. *(a) When abandonment is prohibited, the investment trigger can be given by . (b) When MNC holds the option of abandonment and the project is partially reversible (i.e., ), the optimal investment trigger of MNC is always greater without the abandonment option than with it; that is, . And if the project is irreversible (, the two investment thresholds are the same, .*

Proposition 1 shows that MNC hastens to invest in the extraction project at the presence of abandonment option and the abandonment option produces the acceleration effect for investment. That is, the abandonment option provides downside protection for MNC and has a negative effect that pulls down the investment trigger. Therefore, MNC with the option of abandonment has greater flexibility and encourages MNC to invest earlier for more profits. In the cooperative extraction project with uncertainty and irreversibility, the acceleration effect makes foreign direct investment contribute to economic growth of HC, which is consistent with Borensztein et al. [40]. To attract a foreign direct investment and have a positive effect on overall economic growth of HC, HC should adopt many policy measures and provide the MNC with more managerial flexibility to induce more investment.

Proposition 2. *Irrespectively of whether MNC is endowed with the abandonment option or not, the optimal investment timing is negative with the profit share.*

The intuition of Proposition 2 is as follows. As the profit share goes up, the investment trigger goes down and the presence of the abandonment options has no influence on the relationship between the investment trigger and profit share. As such, the investment trigger is inversely related to the profit share.

#### 5. Nash Bargaining Game about the Optimal Profit Sharing

The determination of profit share can be solved by Nash bargaining game. The bargaining process is carried out between MNC and HC. We derive the solution about the optimal profit share by the Nash Bargaining Solution, which is created by Harsanyi [41, 42] and Rubinstein (1987). Both players must find an explicit agreement on profit distribution before project runs. So we can view this situation as a cooperative game and derive a Nash Bargaining Solution (NBS), which can be solved by maximizing the joint profit of both players.

Both players share the same information about future profit for extractive project and are adverse to internal conflicts before the project runs. They must reach an agreement about the profit distribution by maximizing the joint objective function . Because of the uncertainties of future profit flow and the market volatility, both players, respectively, determine the profit share, according to being with or without the abandonment option. It is assumed that the profit share of MNC is and , respectively, according to MNC without and with the option of abandonment.

As in Moretto and Rossini [43, 44], the joint objective profit function of both players can be expressed as , where and , respectively, are defined as the utility function of MNC and HC and and are disagreement payoffs. For both players, if the bargaining fails, they will not invest in the project and possess zero utility. So, it is assumed that . Because the determination of profit sharing is prior to investment, the profit flow satisfies or . In addition, as in Moretto and Rossini [43], it is assumed that and , where they, respectively, represent the Von-Neumann-Morgenstern utility of MNC and HC and and denote the degrees of relative risk aversion of both players, respectively.

Both players play cooperative game at or and determine the optimal profit share or by maximizing the joint objective utility function. Then, cooperative objective function for determining the optimal profit share can be given byDifferentiating (34) with respect to , we get where .

##### 5.1. Optimal Profit Share in the Absence of the Abandonment Option

Proposition 3. *When the abandonment option is absent, the optimal profit share, , can be given by*

The result is consistent with Di Corato [33]. However, Di Corato [33] focuses on the outcome of profit sharing under the threat of nationalization, which is different from the model setting. From (36), the optimal profit share is related to the relative risk aversion ratio . We get , all other things being equal. It indicates that the greater the relative risk aversion ratio , the smaller the optimal share, which implies that MNC must compensate for HC with more risk aversion with a higher profit share.

##### 5.2. Optimal Profit Share at the Presence of the Abandonment Option

For given , substituting (31) and (33) into (35), maximizing (35) at and differentiating (36) with respect to , we can get Equation (37) indicates that the optimal profit share is related to the volatility , the relative risk aversion ratio , the interest rate , and the recovery rate and the expression explicitly includes investment threshold . Therefore, in order to identify both optimal trigger and optimal profit share (i.e., and ), (30) and (37) must be solved simultaneously.

Proposition 4. *If the relative risk aversion ratio , the optimal profit share with the option of abandonment is always smaller than that without ; that is, .*

Proposition 4 shows that introducing the abandonment option induces MNC to lower its optimal profit share, thereby making MNC more reluctant to invest in the extraction program. It surprisingly uncovers that a risk-averse MNC with the abandonment option has a lower profit share. Moreover, Proposition 2 shows that the profit sharing ratio is negative with the investment trigger, which indicates that the more the profit sharing, the earlier to investment the project under the two cases. According to Proposition 4, MNC with risk aversion will lead to investing later in extraction program and is consistent with Proposition 2 and will ask for more profit sharing to induce the investment. It reflects that the attitude to the risk of investment will influence the profit sharing and further the investment timing. Hence, the abandonment option has negative effect on the investment.

Proposition 5. *The abandonment option has two opposite effects on the optimal investment trigger.*

Proposition 1 captures the positive effect of the abandonment option on the investment. And the flexibility to abandon the project provides the downside risk for MNC, therefore inducing MNC to invest earlier, which pulls down the investment trigger. On the other hand, the combination of Propositions 2 and 4 shows the abandonment option has a negative effect on the extractive investment, which lifts up the investment trigger. Hence, the effect of the abandonment option on investment has an ambiguous impact.

#### 6. Results

In this part, we first analyze some properties of profit shares and in the cooperative game and then discuss the impact of market volatility, , the expected growth rate, , and the relative degree of risk aversion, , on the optimal profit shares and under two scenarios. Next, the analysis and comparison of two investment thresholds and will be obtained. Similarly to Di Corato [33] and Wong [32], we use the parameter values as follows: , , , , , and .

##### 6.1. Relationship of Profit Shares and in Two Cases

###### 6.1.1. On the Impact of Volatility

According to (30), (36), and (37), Figure 1 plots the optimal profit shares and with the volatility at different relative risk aversion ratio . From Figure 1, it can be shown that both profit shares and accordingly decrease as volatility increases. When the relative risk aversion ratio increases and is near 10%, HC is more risk averse than MNC. In order to make the two players reach an agreement to run the project together, less risk-averse MNC gets a lower share of the profits and makes risk-averse HC large gains, which accordingly makes the difference between the two investment thresholds larger and larger. When the volatility increases over 10%, there will be the opposite. Therefore, the actual determined profit share ratio should be based on the degree of risk aversion and uncertainties in cooperative project.

###### 6.1.2. On the Impact of Expected Growth Rate

As seen in Figure 2, an increase in the expected growth rate, , lowers the optimal profit shares and . These show that when the market environment becomes better, the potential future earnings are relatively high, and MNC will give up an additional portion of the profit share to induce cooperation with HC. Observe from Figures 1 and 2 that no matter how the parameter values change, the optimal profit share with the exit option is always less than without and the greater the relative risk ratio is, the more sharply the graph decreases, which indicates that the impact of the risk attitude of MNC on the optimal profit share dominates that of the expected growth rate. Therefore, HC should firstly consider the risk appetite of MNC in the bargaining process to determine the optimal share of profits in cooperative framework.

##### 6.2. The Analysis of Investment Thresholds

In this section, we discuss how the investment thresholds change with the profit share , the volatility , and the expected growth rate under two scenarios.

###### 6.2.1. Effect of Share of Profits on the Investment Thresholds

Figure 3 has shown the relationship between investment thresholds and profit shares . With the base case parameter values, the solutions to (9), (21), (30), (36), and (37) are as follows: optimal exit trigger , optimal investment trigger with the abandonment options , optimal investment trigger without the abandonment options , optimal profit share under no exit options , and optimal profit share with the option of abandonment . To further understand the difference of the two investment triggers, we suppose the initial value of the variable, , is 0.1266, since the investment timing with the abandonment option is 0.1266. As discussed in Sarkar [45], the expected time for the variable from to is infinite by calculating and the arrival probability is 95.84% with the use of the expression: . That is, once the abandonment options are accounted for, MNC will be hastened to invest in the project with the accelerated effect. In contrast, MNC without the abandonment options will delay a longer time by numerical analysis. Thus, the effect of the abandonment option on the optimal investment timing is economically significant.

**(a)**

**(b)**

In addition, Figure 3 shows the threshold is reduced with share under two scenarios. The abandonment option has two opposite effects on the investment in general, one is the positive effect, thereby pulling down the investment trigger, and the other is the negative effect by increasing the critical investment value. We identify that the overall effect of the abandonment options is inversely related to the investment trigger through Figure 3.

###### 6.2.2. Relationship between Volatility and Investment Thresholds

Figure 4 has shown the impacts of volatility and risk aversion on and . From the graph, the investment threshold with the option of abandonment is always larger than that without, which is in line with Proposition 1. And the investment threshold is positively related to the volatility. The relationship of the change rate and the relative degree of risk aversion are determined in the curve. When is comparatively small (), the little change of investment threshold is shown. Meanwhile, the gap of two investment triggers is becoming wider and wider with the increasing of . All these show that the relative degree of risk aversion plays an important role in the investment decision and MNC with more risk aversion increases investment threshold and postpones investment, while the profit sharing of MNC at this time is also reduced by combining Figure 1 with Figure 3. And we see that as the relative risk aversion ratio increases, the reduction of profit shares will enlarge investment threshold.

###### 6.2.3. Relationship between Expected Growth Rate and Investment Threshold at Different Risk Aversion Ratio

Figure 5 shows the relationships between the growth rate and two investment thresholds. When is very small (), along with the increasing of , that is, and , the investment triggers will reduce. The change rate of to will be larger than the change rate of to , making the curve descend. However, when increases to over 1, two investment thresholds will increase. This shows that when HC is increasingly risk averse, the profit sharing will get smaller and smaller with the expected growth rate of the project. Since profit sharing has a negative effect on investment thresholds, MNC will postpone investment with profit sharing decreases. At this point, the negative effect of profit sharing on investment thresholds dominates that of the growth rate; hence, the curve of investment thresholds shows an increasing trend, making MNC delay the investment.

#### 7. Conclusions

In this paper, we examine the investment timing of foreign direct investment and the optimal profit share between HC and MNC with an option of abandonment in a cooperative framework. Combining the real options with bargaining game, the results show that when the project is partially reversible in the presence of abandonment option, the investment threshold of FDI is always less than that under no exit option and the abandonment option has a negative impact on the investment trigger. When the project is completely irreversible, the investment timing in both cases remains the same. In addition, we demonstrate the relationship between the profit shares without an exit option and when there is an exit option. From the study, it can be shown that if the relative risk aversion ratio is greater than some critical value, is always larger than , which shows the introduction of the abandonment options has a positive effect on investment trigger since the profit share is inversely related to the investment trigger. Using the numerical analysis, we verify the total effect of the abandonment option is negative. MNC with management flexibility will be more eager to invest in the project.

Although this paper draws some practical conclusions, it did not consider the impacts of the political risk on the investment of MNC. If we incorporate the change of tax rate or nationalization into the model, the relationship of the investment timing and the profit sharing under political risk will be further studied. This is the future direction of study.
