Economic and Environmental Benefits of Eliminating Log Export Bans – The Case of Costa Rica

An increasing number of tropical timber‐producing nations have enacted bans on export of logs arguing that this will reduce deforestation, expand downstream wood processing and improve the scale efficiency of domestic processing, create jobs and retain more value‐added nationally. The theoretical literature is clear that trade restrictions are generally welfare reducing (except in special cases such as when there is a potential for an optimal export tax). At best, a log export ban is a second‐best policy tool for reducing deforestation and addressing the associated environmental externalities. In overall terms, the suggestion that log export bans can achieve the objectives expected of them is dubious. However, very little quantitative evidence exists to demonstrate this claim and the paper attempts to address this gap by looking at the economic and environmental impacts of eliminating a log export ban in Costa Rica. The authors argue that eliminating the export ban is Pareto improving and could generate economic gains as high as $14 million per annum with the possibility of relatively modest environmental benefits.     

Consumer demand functions,Spain, 1958–1964

Barten's maximum likelihood method (European Economic Review, Fall 1969) is used to estimate demand systems for Spain, under the assumptions of constant elasticities and constant marginal budget shares, respectively. It is shown in which sense the second assumption gives “better” results. In both cases, the homogeneity restriction is rejected, using the maximum likelihood ratio test. But once homogeneity is imposed, the symmetry restriction cannot be rejected.     

Analysis of efficiency and profitability of franchise services

The present study analyses the relative efficiency of franchise services and characterises the best companies, confirming the relationship between efficiency and profit. These companies are from ‘the trade and other services sector', the main group of service-providing companies in the Spanish economy. The methodology calls for first comparing the relative efficiency of franchisers and ownership enterprises. Second, the focus turns to the most efficient franchise services, using a super-efficiency model to rank them. The paper then goes on to cover the analysis of the main characteristics of the best franchise enterprises, the number of own establishments in a franchise business and the profitability of the company. This paper presents arguments as to why companies from the trade and other services sector are included. The main conclusion is that, whilst the number of establishments is irrelevant in achieving greater efficiency, many of the most efficient enterprises have high returns.     

Emerging market fluctuations: What makes the difference?

Aggregate fluctuations in emerging countries are different from those in developed countries. Using data from Mexico and Canada, this paper decomposes these differences in terms of reduced form shocks that affect aggregate efficiency and distort the decisions of households about how much to invest, consume, and work in a standard model of a small open economy. The decomposition exercise suggests that most of these differences are explained by fluctuations in aggregate efficiency, distortions in labor choices over the business cycle, and distortions in intertemporal consumption choices. Successful models for emerging markets fluctuations should include primitive shocks and frictions that generate these features. Models with financial frictions in the form of working capital constraints, possibly augmented with endogenous collateral constraints, are consistent with these findings.     

Risk premia and seasonality in commodity futures

We develop and estimate a multifactor affine model of commodity futures that allows for stochastic seasonality. We document the existence of stochastic seasonal fluctuations in commodity futures and that properly accounting for the cost‐of‐carry curve requires at least three factors. We estimate the model using data on heating oil futures and analyze the contribution of the factors to risk premia. Correctly specifying seasonality as stochastic is important to avoid erroneously assigning those fluctuations to other risk factors. We also estimate a nonlinear version of the model that imposes the zero lower bound on interest rates and find similar results.     

The extended linear expenditure system

The purpose of this paper is to derive the aggregate consumption function associated with the linear expenditure system (LES) from simple utility maximization procedures. The parameter set (β, γ) of LES plus an added parameter (μ: the ratio of the subjective rate of discount to the market rate of interest) characterize the consumption-savings and the expenditure allocation decisions under the Klein-Rubin utility function. The term p′y appears in the aggregate consumption function.The distinction between subjective, planning time and historical time (a continuum of initial points of optimal plans) is basic here: thus the focus on solutions at t = 0.     

The impact of degenerative episodes on the sponsorship B2B relationship: Implications for brand management

Sponsorship B2B relationships generally are entered into by sponsors seeking brand-related benefits through association with a sport entity brand. Negative incidents involving athletes representing the sport entity may threaten the brands of both the sport and sponsor and can weaken or even dissolve the partnership. The management of these episodes is critical in protecting the sport entity's brand equity, as well as the sponsor's brand, and ultimately the relationship. This study explores multiple stakeholders' perspectives on these degenerative episodes and the potential relational outcomes using a series of depth interviews with major sponsors and sport entities. We identify key constructs such as attribution of blame, societal norms, zone of tolerance and perceived severity which influence whether this behavior acts as a degenerative episode in the relationship. Factors such as existing relationship quality and episode management can affect the impact on the relationship as well as the extent of relational change.     

The Effect of Perceived Value and Switching Barriers on Customer Price Tolerance in Industrial Energy Markets

Purpose: This article analyzes the effects of perceived value, satisfaction, and switching barriers on price tolerance. It also examines the moderating effect of switching barriers.

Methodology/Approach: Empirical research was conducted by collecting information from a sample of 326 major gas and electricity consumers in a newly liberalized industrial market with a high concentration of suppliers.

Findings: Switching barriers are the main antecedent to price tolerance. Price tolerance of industrial customers depends directly on switching barriers more than on satisfaction. The customer satisfaction construct is a necessary but not sufficient predictor of price tolerance. While satisfaction has an effect on price tolerance, the effect of perceived value on price tolerance is only indirect through satisfaction, even though it may produce positive direct effects when there are high switching barriers.

Originality/Value/Contribution: For the first time in a B2B framework, the moderating effects of switching barriers on the relationship between perceived value, satisfaction, and price tolerance have been analyzed.     

Pricing of Defaultable Bonds with Log-Normal Spread: Development of the Model and an Application to Argentinean and Brazilian Bonds During the Argentine Crisis

In this paper we describe a two-factor model for a defaultable discount bond, assuming log-normal dynamics with bounded volatility for the instantaneous short rate spread. Under some simplified hypothesis, we obtain an explicit barrier-type solution for zero recovery and constant recovery. We also present a numerical application for Argentinean and Brazilian Sovereign Bonds during the default crisis of Argentina.JEL Classification: G 13
