A voting paradox of fiscal federalism

This paper draws attention to certain tensions within fiscal federalism. We compare median- voter decisions on the socialization of goods and services at different levels of government. They show typical differences which are primarily due not to changes in the economic or political situation but to changes in the level of decision making.     

The role of credibility in the cyclical properties of macroeconomic policies in emerging economies

Optimal stabilization policy is countercyclical, aiming at keeping output close to its potential. However it has been traditionally argued that emerging countries are unable to adopt countercyclical monetary and fiscal policies. Here we argue that the cyclical properties of macroeconomic policies depend critically on policy credibility. We test this proposition by making use of recent panel data for eleven emerging market economies and time series data for Chile. The evidence supports that countries with higher credibility, as reflected by lower country risk levels, are able to conduct countercyclical fiscal and monetary policies. Conversely, countries with less credible policies (and, therefore, with higher country risk spreads) contribute to larger cyclical fluctuations by applying procyclical policies. For Chile we find that both monetary and fiscal policies have been largely countercyclical after 1993. JEL no. E43, E52, E62     

Efficiency and truthfulness with Leontief preferences. A note on two-agent,two-good economies

In exchange economies where agents have private information about their preferences, strategy-proof and individually rational social choice functions are in general not efficient. We provide a restricted domain, namely the set of preferences representable by Leontief utility functions, where there exist mechanisms which are strategy-proof, efficient and individually rational. In two-agent, two-good economies we are able to provide an even stronger result. We characterize the class of efficient and individually rational social choice functions, which are fully implementable in truthful strategies.Received: 28 April 2003, Accepted: 23 June 2003, JEL Classification: D51, D71The author thanks Matthew Jackson, Jordi Massó and James Schummer for fruitful discussions, William Thomson for many valuable comments on an earlier version.

Dynamic Optimization of Long-Term Growth Rate for a Portfolio with Transaction Costs and Logarithmic Utility

We study the optimal investment policy for an investor who has available one bank account and n risky assets modeled by log-normal diffusions. The objective is to maximize the long-run average growth of wealth for a logarithmic utility function in the presence of proportional transaction costs. This problem is formulated as an ergodic singular stochastic control problem and interpreted as the limit of a discounted control problem for vanishing discount factor. The variational inequalities for the discounted control problem and the limiting ergodic problem are established in the viscosity sense. The ergodic variational inequality is solved by using a numerical algorithm based on policy iterations and multigrid methods. A numerical example is displayed for two risky assets.     

How wide is the gap? An investigation of gender wage differences using quantile regression

In this paper we re-examine the link between subjective perceptions and objective measures of wage discrimination by estimating the mean and several quantiles in the conditional wage distribution of men and women in order to decompose the gender wage gap into the part attributed to different characteristics and the part attributable to differential returns to these characteristics at points other than the conditional expectation. In the process we take into account the endogeneity of educational choice and the participation decision of women. The results suggest that the absolute wage gap and the component of the latter that can be attributed to different returns to characteristics increase over the wage scale.     

The trade balance and the terms of trade in a two-country two-sector OLG economy

We consider a two-country, two-sector OLG model. It is shown that the trade balance and the relative price of exports are always positively related when exports are labor intensive regardless of the elasticity of intertemporal substitution in consumption. A large response of savings to future prices becomes a sufficient condition for an inverse relation between these variables only if exports are capital intensive. In this case, a rise in the terms of trade can be followed by a trade balance decline if consumption goods are capital intensive and the income effect implied on savings is negative and large.     

The effects of public infrastructure on the cost structure of Spanish industries

This paper examines the impact of public infrastructures on the performance of Spanish private business at a disaggregated industry level. We use duality theory to recover the productivity effects of public capital by calculating the cost saving effects that are associated to public services. Using a translog cost function we present panel estimates for 14 Spanish industries during the period 1980–1991. Our results strongly suggest that public capital formation can be considered to be an instrument to improve competitiveness by reducing production costs. However, the results also indicate that there is a technologically induced labor saving effect through higher public investment. Furthermore, our estimates suggest that a distinction among industries is of importance because the effects of public infrastructures vary across industries considerably.     

Internal and external exchange rate equilibrium in a cointegration framework. An application to the Spanish peseta

A simple cointegration methodology is used to compute the equilibrium real exchange rate for the peseta. The stock of foreign assets and the evolution of sectoral prices are considered to be the fundamentals for the real exchange rate. After testing for cointegration, we proceed to decompose the series into a permanent and a transitory component, following the method devised by Gonzalo and Granger. The permanent component of the real exchange rate corresponds to its (time-varying) equilibrium value, and the deviation of the actual real exchange rate from this equilibrium value gives an estimation of the degree of misalignment of the real exchange rate. By the end of the sample (1998:1), the peseta is estimated to be undervalued around 6%.     

Search Cost and Price Dispersion in Vertically Related Markets: The Case of Bank Loans and Deposits

Using data on marginal interest rates of loan and deposit products by Spanish banks, we find that the level of interest rates on loans (deposits) across geographic markets decrease (increase) with the number of banks in each market, and that the level of interest rates on loans increases with the level of interest rates of deposits. We also find that the dispersion of interest rates of both loans and deposits increase with the number of banks. This evidence is interpreted as evidence of customer’s search costs in retail banking, consistent with predictions from the Carlson and McAfee (J Polit Econ 91:480–493, 1983) model of market competition with search costs.
