International Capital Mobility and the Costs of Us Import Restraints*

Abstract This paper evaluates general equilibrium welfare effects of tariffs, quotas, and voluntary export restraints under different assumptions about international capital mobility. We show analytically that, when induced terms-of-trade and rental-rate effects are considered, the qualitative influence of capital mobility on the costs of protection cannot be ascertained unambiguously. Simulation estimates for the US indicate the practical importance of capital mobility, as well as of terms-of-trade and rental-rate adjustments, in determining the ultimate welfare effects of import restraints.     

Collateral or utility penalties?

In a two-period economy with incomplete markets and possibility of default we consider the two classical ways of enforcing the honoring of financial commitments: by using utility penalties and by using collateral requirements that borrowers have to fulfill. First, we prove that any equilibrium in an economy with collateral requirements is also an equilibrium in a non-collateralized economy where each agent is penalized in their utility if his or her delivery rate is lower than the payment rate of the financial market. Second, we prove the converse: any equilibrium in an economy with utility penalties is also an equilibrium in a collateralized economy. For this to be true, the payoff function and initial endowments of the agents must be modified in a quite natural way. Finally, we prove that the equilibrium in the economy with collateral requirements attains the same welfare as in the new economy with utility penalties.     

Has Distance Died? Evidence from a Panel Gravity Model

The estimated coefficient of distance on the volume of tradeis generally found to increase rather than decrease throughtime using the traditional gravity model of trade. This distancepuzzle proved robust to several ad hoc versions of the modelusing data for 1962–96 for a large sample of 130 countries.The introduction of an "augmented" barrier to trade functionremoves the paradox, yielding a decline in the estimate of theelasticity of trade to distance of about 11 percent over the35-year period for the whole sample. However, the "death ofdistance" is shown to be largely confined to bilateral tradebetween rich countries, with poor countries becoming marginalized.     

US—Mexico fresh vegetable trade: the effects of trade liberalization and economic growth

Studies of US‐Mexico vegetable trade have generally emphasized the importance of US tariffs in determining the competitive advantage of US producers. Even so, research has identified at least four factors related primarily to the different levels of economic development in the US and Mexico that also have important effects on US‐Mexico agricultural trade in general and fresh vegetable trade in particular. These include the differential growth rates of US and Mexican real wages, production technology (yields), and per capita income as well as cyclical movements in the real Mexican Peso/US Dollar exchange rate. This study examines the relative contribution of NAFTA and the development‐related factors to likely future changes in US fresh vegetable imports from Mexico. The analysis employs an econometric simulation model of US and Mexican markets for five fresh vegetables (tomatoes, cucumbers, squash, bell peppers, and onions) accounting for 80% of US fresh vegetable imports. The results suggest that the 1994–1995 Peso devaluation rather than NAFTA was primarily responsible for the sharp increase in US imports of Mexican vegetables observed in the first years following the implementation of NAFTA. Over time, however, the results suggest that differences in the growth rates of US and Mexican production yields and, to a lesser extent, of US and Mexican real incomes and/or real wage rates could plausibly contribute more to the future growth of US tomato, squash, and onion imports from Mexico than the trade liberalizing effects of NAFTA.     

Institutional Constraints,Stakeholder Pressure and Corporate Environmental Reporting Policies

Within the theoretical framework of socio‐political economics, and more specifically of stakeholder theory, this work examines whether companies operating under different institutional constraints and stakeholder pressure tend to emphasize different models of corporate environmental reporting. Furthermore, the paper tests whether different corporate environmental reporting policies are driven by the countries' corporate governance systems. A sample of 3931 international companies was examined through a logistic biplot and conditional mean linear regression models. The main results reveal that companies follow two distinct environmental reporting approaches, which depend on specific stakeholders and institutional requirements. The first model, which is followed by firms within codified law countries, mostly focuses on water and emissions. The second approach, mainly followed by companies operating in common law countries, emphasizes materials and energy issues. This finding reveals that companies gradually modify their environmental strategies to make themselves more compatible with the characteristics of the social and institutional environment, which will result in several corporate benefits. The paper provides several outstanding implications for companies' strategic managers, national institutions and firms' stakeholders, especially for investors and customers.

Diseconomies of Size with Fixed Managerial Ability

Managerial ability has important implications for farm growth. In this article we first show in a production model that increasing output with a fixed level of managerial ability can lead to a decrease in profits. Next, we discuss the effect that managerial ability has on economies of size. In the empirical part, economies of size are estimated for a sample of dairy farms using a proxy for managerial ability, which is calculated as a technical efficiency index. The results show that increasing farm size while holding managerial ability constant can be an important source of diseconomies of size.     

Followers' entry timing: evidence from the Spanish banking sector after deregulation

Much of the literature dedicated to the analysis of entry timing decisions has been devoted to the study of their consequences in terms of performance. However, only a limited amount of effort has been dedicated to analyzing the factors that determine these decisions. In addition, previous papers have centered their efforts on the product dimension, paying no attention to entry into new geographical markets. This paper departs from previous works in this respect and extends the entry timing literature through a consideration of the geographical side of entry. Our analysis shows that organizational size, organizational competence, and organizational experience appear as key factors when explaining the pattern of geographic diversification. Our results also indicate that diversification takes place sequentially, first proceeding to closer locations, then occupying markets further from the origin.

Optimal exploration investments under price and geological‐technical uncertainty: a real options model

This article develops a real options model for valuing natural resource exploration investments (e.g. oil or copper) when there is joint price and geological‐technical uncertainty. After a successful several‐stage exploration phase, there is a development investment and an extraction phase. All phases are optimized contingent on price and geological‐technical uncertainty.
Several real options are considered. There are flexible investment schedules for all exploration stages and a timing option for the development investment. Once the mine is developed, there are closure, opening and abandonment options for the extraction phase. Our model maintains a relatively simple valuation structure by collapsing price and geological‐technical uncertainty into a one‐factor model.
We apply the model to a copper exploration prospect and find that a significant fraction of total project value is due to the operational, development and exploration options available to project managers.
