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.     

Technical efficiency and farm size: a conditional analysis

The relationship between technical efficiency and size might be affected by farm heterogeneity. We analyse this relationship conditional on a set of control variables. These control variables are chosen using a production model where technical efficiency is introduced as a parameter. As a result, technical efficiency affects both the input demand and the output supply of a profit maximising producer. The empirical application explores these issues using panel data of dairy farms in Spain.     

Multipoint competition,strategic similarity and entry into geographic markets

The objective of this study is to integrate both multimarket contact and strategic similarity in the analysis of entry decisions. We also analyze the role of the reciprocity of contacts, market concentration, and coordination mechanisms at moderating the relationship. Our hypotheses are tested through the analysis of entry behavior into new geographical markets in the Spanish savings bank market. Interestingly, our results offer an opportunity of conciliating conflicting evidence in both the multimarket–mutual forbearance and the heterogeneity–rivalry literatures and offer further support to the U‐inverted influence of multimarket contact on entry. Given the coordination assumption implicit in the theory and the possible presence of unobservable variables, we also offer a method to cope with the common‐actor problem.

Consumption Externalities,Habit Formation and Equilibrium Efficiency*

We analyze the welfare properties of the competitive equilibrium in a capital accumulation model where individual preferences are subject to both habit formation and consumption spillovers. Using an additive specification for preferences, according to which the argument in the utility function is a linear combination of present and past values of own consumption and consumption spillovers, we analyze the circumstances under which these spillovers are a source of inefficiency. It is shown that consumption externalities have to interact with habits in order to generate an inefficient dynamic equilibrium. Finally, we characterize optimal tax policies aimed at restoring efficient decentralized paths.     

The Discount Rate in Emerging Markets: A Guide

There is considerable controversy about the correct discount (or "hurdle") rate to use when performing valuations of investments in real assets in emerging markets. The topic is particularly relevant because of the growing need to evaluate privatizations, direct private acquisitions, and greenfield investments in new productive facilities throughout the world.
This article argues that the traditional practitioners' approach of building a country risk premium into the discount rate is generally inappropriate, mainly because country risk is not the same for all projects nor is it totally systematic. Moreover, there is no reason for the discount rate to be closely related to the spread on the government bonds of the country concerned. The author also points out that, in determining the appropriate discount rate, what is important is not the segmentation of the market, but the extent to which the investor is locally or globally diversified. The article accordingly reviews a selected group of models for calculating discount rates for both segmented and integrated markets. Adjustments to the valuation procedure are also suggested for cases in which investors are not well diversified or the investment is illiquid.     

Convergence in the Americas: Some Lessons from the DR‐CAFTA Process

The proliferation of trade agreements in the Americas is a major cause for concern as it might fragment or inhibit the emergence of a hemispheric trading system. In addition to establishing a free trade area between the US and six countries in Latin America, the DR‐CAFTA consolidates a set of trade arrangements among those six Latin American countries. The approaches and techniques employed to achieve this consolidation should be studied by policy analysts and negotiators of broader hemispheric‐wide negotiations since the DR‐CAFTA is in fact a microcosm of the spaghetti bowl of trade agreements now existing in the Americas. This paper points out the potential consequences of the proliferation of trade agreements in the Americas and provides an analysis of the convergence techniques and approaches used in the DR‐CAFTA, in particular in the areas of market access and rules of origin.
