Remittances and income diversification in Bolivia’s rural sector

This article examines the role of remittances in income diversification strategies in Bolivia’s rural sector. Remittances can be consumed or invested by the recipient. As an investment, funds can be used for farming or to finance other nonfarm productions. In this article, we use a large and nationally representative survey to estimate the effect that remittances have on the probability of producing income from nonfarm activities (diversification) by using a bivariate probit model. Our evidence shows that remittances increase the probability that a rural family engages in nonfarm activities, at least in some regions of Bolivia. We also find evidence that the sender’s decision to remit and the recipient’s decision to diversify may be jointly determined. As such, this suggests that remittances may serve as a mechanism to overcome localized failures in Bolivia’s capital markets.     

On the constancy of real interest rates

In the context of a small structural model, we show that the autocorrelation and the variance of the ex ante real rate of interest can be uniquely estimated; the random forecasting errors need not confound the problem of identifying variations in the real rate.     

Can cross–border pollution reduce pollution?

We develop a two–country model of foreign aid and cross–border pollution resulting from production activities in the recipient country. There is both private and public abatement of pollution, the latter being financed through emissions tax revenue and foreign aid. We characterize a Nash equilibrium in which the donor country chooses the amount of aid and the recipient chooses the fraction of aid allocated to pollution abatement and the emission tax rate. At this equilibrium, an increase in the donor’s perceived rate of cross–border pollution reduces emission levels. JEL Classification: Q28, F35, H41 Est–ce que la pollution trans–frontière peut réduire le niveau de pollution? Les auteurs développent un modèle à deux pays d’aide à l’étranger et de pollution trans–frontière résultant d’activités de production dans le pays qui reçoit l’aide. Il existe des efforts privés et publics pour réduire la pollution, ces derniers étant financés par les rentrées fiscales d’une taxe sur la pollution et par l’aide étrangère. On définit un équilibre à la Nash pour lequel le pays donateur choisit le montant de l’aide, et le pays récipiendaire choisit la fraction de l’aide étrangère qu’il allouera à la lutte à la pollution ainsi que le taux de taxation sur la pollution. A cet équilibre, un accroissement dans le taux de pollution trans–frontière perçu par le donataire réduit le taux de pollution.     

Export–Oriented Foreign Direct Investment and Local Content Requirement

We develop a model in which foreign firms locate in a host country and export their produce to another (consuming) country. We consider both exogenous and endogenous numbers of foreign firms. These firms compete with domestic firms in the consuming country under oligopoly. Unemployment exists in both countries. We analyse the conflict of interest between the two countries on the level of local content for the foreign firms. Under free entry of foreign firms, the consuming country may want a less severe restriction on local contents than the host country, but not so when the number of foreign firms is exogenous.     

International Business Alliance under Asymmetric Information: Technology vis‐à‐vis Information Advantage

We study the relationship between a multinational corporation (MNC) and a domestic firm under demand uncertainty. The MNC possesses a superior production technology, but the domestic firm is better at predicting market demand. We examine the MNC's preference for, and the ownership structure of, an international alliance (IA) and find, inter alia, that binding borrowing constraints have serious implications for the results. Interestingly, a firm's preference for and profits in IA do not necessarily increase as its advantage in market information or production technology increases. We also consider a dynamic setting with technology spillover and show that whether technology spillover hinders or facilitates IA once again depends on the nature of the credit market.     

The Supporting Line Property and the Additive Choice Function for Two-Dimensional Choice Problems

The paper provides an axiomatic characterization of the additive choice function using the additivity property. It is seen that, along with Pareto optimality, symmetry, and a supporting line property, the additivity axiom uniquely characterizes the additive choice function. The additive choice function as defined in this paper does not satisfy Nash's assumption of the independence of irrelevant alternatives. This raises the question of when a choice function is representable, an issue addressed in an appendix.     

"Export Experience" under Borrowing Constraints

The paper develops a two‐period, two‐country, multigood model with endogenous investment. Borrowing is subject to quantitative restrictions. The authors examine the effect of promoting exports in period 1 on the level of exports in period 2. They consider a number of scenarios depending on how the initial values of the policy instruments are determined, and compare the “export‐experience” effects under the different scenarios.
