The effects of macroeconomic stability on foreign trade. An analysis for Spain, 1986–2000

Two main factors underlie the rebirth of interest in the study of the influence of the real exchange rate on trade, the reduction of its volatility and the current trend towards price stability. The objective of this study is to analyse the effects of the process of nominal convergence, required of the European member states for the fulfilment of monetary integration, on foreign trade flows. The case of Spain, which is especially interesting in this context, is studied for the period 1986 to 2000. The results of estimating the aggregate functions of the export and import of goods shows how macroeconomic stability has altered the behaviour of trade with respect to the two basic determinants – income and prices – how it has caused a significant structural change in the real exchange rate and, finally, how it has laid the explanatory bases for transactions in the twenty-first century with the single currency – the euro.     

Interest rates,expectations and the credibility of the Bank of Spain

The purpose of the paper is to pinpoint the date of the change of monetary policy regime which occurred in Spain during the year 1984, when it moved away from controlling monetary aggregates towards interest rate targeting. The most likely date for the change is estimated and, surprisingly, there is evidence that agents learned about the new intermediate target quite rapidly.A week after the change, the term structure of interest rates showed how market agents attributed much more informational content to interest rate changes than they had previously. Two types of transitions are tried: a one-step and a gradual logistic swithing function.     

Entrepreneurial Structure Qualitative Analysis: The Case of Seville (Spain)

In the field of territorial economic growth, it is possible to identify important characteristics in the entrepreneurial structure, such as the structure of the size of firms, main activity sectors, or the degree of innovation. However, other lesser known characteristics are important also, such as functional dependency, which considers the relationship between small and medium enterprises (SMEs), and suppliers and clients belonging to any territorial field or productive dependency, which considers the level of concentration in terms of buying and selling in connection with the main suppliers and clients, respectively. In order to empirically contrast the importance of these entrepreneurial characteristics and try to relate them with territorial economic growth, a sample of 400 enterprises in the province of Seville (Spain) is used.      

‘Adopt a Hypothetical Pup’: A Count Data Approach to the Valuation of Wildlife

The willingness to pay (WTP) for a coyote conservation program is estimated using a novel payment-vehicle, based on how many ‚problem’ coyotes respondents would be willing to sponsor for a year. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince Edward Island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses. This is particularly important in the case of coyotes, often regarded as an economic bad. Estimates of WTP per coyote per year around $18–$22 and annual WTP per contributor of about $46–$57 are obtained.      

Environmental Product Differentiation and Environmental Awareness

In this paper, we have considered a duopolistic model of environmental product differentiation with two types of consumers (green and brown) to analyze how environmental awareness affects the environment. “Green” consumers value the physical and environmental attributes of the good they purchase while “brown” consumers only value the physical attributes. We find that more environmental awareness may not be good news for the environment as the firm that produces the good without environmental attributes may increase its sales. The result depends on the degree of product differentiation and the cost to achieve it. Social welfare can also be inversely related to environmental awareness if the negative environmental effect dominates the positive market effect.      

Going Through Hell: Increased Work Effort in the Aftermath of Terrorism in Norway*

I analyze how sickness‐absence behavior in Norwegian municipalities was affected by exposure to the terrorist attack in Norway in 2011. The main finding is that in municipalities from which a resident was killed in the attack, sickness absence declined by 4 percent compared with municipalities without victims. The effect is precise, stable, and persistent. The results do not seem to be driven by changing labor market composition. The effect is found also in neighboring municipalities and is larger for people close to the age of the victims.     

Graph efficiency and productivity measures: an application to US agriculture

Hyperbolic measures of efficiency and productivity change with respect to a graph representation of production technology allow researchers to consider output and input dimensions simultaneously in measuring producer performance. Hyperbolic efficiency measures have been proposed, but empirical implementation has not followed, either in efficiency analysis or in productivity analysis. The objectives of this paper are to define hyperbolic performance measures on a graph representation of production technology, to motivate their use by stating some of their advantages over their radial counterparts, and to introduce a direct formulation to calculate them making use of Data Envelopment Analysis techniques. The ideas are illustrated by calculating hyperbolic efficiency and Malmquist productivity indexes for a US agricultural panel data set.     

The determinants of trade performance: influence of R&D on export flows

A theoretical model is presented, in which supply side differences between countries determine international trade flows. This model is empirically tested at a sectoral level for a group of EU countries, within a framework that focuses on changes through time and differences between countries. The results show that the validity of the theoretical model is limited at sectoral level. However, as expected, we find that the variable representing technological differences is significant and correctly signed for high-technology sectors. The evidence points to the existence of different production functions across countries and to the importance of supply side factors in determining the direction and the terms of trade.     

Coffee export booms and monetary disequilibrium: some evidence for Colombia

The theoretical models that analyse the monetary consequences of export booms show that under a regime of fixed exchange rates, they affect not only the demand for money, via real income, but also the money supply via foreign exchange accumulation. Within this theoretical framework, this study proposes an empirical approach to determine whether the coffee booms of the second half of the 1970s and mid–1980s led to excess money supply in the Colombian economy. The findings provide evidence in favour of a direct association between coffee export booms and excess money supply, implying that external disturbances jeopardize the ability of the economic authorities to carry out successful monetary policy.
