“Green” consumers appear to accept individual responsibility for public good provision. The propensity to take such responsibility may depend on beliefs about others’ behavior, even for consumers motivated by internalized moral norms, not by social sanctions. This can produce multiple...

We consider a framework for analyzing panel data characterized by: (i) a system of regressions equations, (ii) random individual heterogeneity in both intercepts and slope coefficients, and (iii) unbalanced panel data, i.e., panel data where the individual time series have unequal length. A...

A Box-Cox structural utility model is estimated on tax evasion survey data and it is shown that this model gives a better representation of individual utility maximizing behavior than a flexible model, represented by a polynomial of degree 3. It is found that an overall wage increase has a...

This paper shows why regressing the realised rates of depreciation within the exchange rate band on a given information set and conditional on (ex-post) actual no-realignment (à la drift adjustment) still encounters a Peso Problem. Such a procedure generally gives inconsistent estimates. The...

Policies to reduce emissions of greenhouse gases such as CO2 will affect the rate and pattern of technological change in alternative energy resources and other production processes. Imperfections in markets for non-polluting technologies imply that a decentralised economy does not deliver a...

Proper consistency is defined by the properties that each player takes all opponent strategies into account (is cautious) and deems one opponent strategy to be infinitely more likely than another if the opponent prefers the one to the other (respects preferences). When there is common certain...

We study a labor market where worker’s disutilities of effort differ, firm’s outputs depend on the joint efforts of many workers, and individual worker characteristics cannot be observed or inferred by firms. Under assumptions similar to those in Holmström (1982), we demonstrate that an...

How do firms differ, and why do they di.er even within narrowly defined industries? Using evidence from six high-tech, manufacturing industries covering a 24-year period, we show that di.erences in sales, materials, labor costs and capital across firms can largely be summarized by a single,...
