Environmental and tax policies and the optimal provision of clean and dirty public goods are analysed within the context of a second-best framework of optimal taxation. Households consume both clean and dirty commodities. Degradation of the natural environment occurs due to the consumption of...

This paper reviews recent developments in the study of the so-called "double dividend", i.e. the possibility of improving the environment and, at the same time, reducing the distortions of the tax system through revenue-neutral green taxes. Recent modeling advances are considered at both the...

We measure the consequences of asymmetric information and imperfect competition in the Italian lending market. We show that banks’ optimal price response to an increase in adverse selection varies with competition. Exploiting matched data on loans and defaults, we estimate models of demand for...

This Paper studies optimal fiscal and monetary policy under imperfect competition in a stochastic, flexible-price, production economy without capital. It shows analytically that in this economy the nominal interest rate acts as an indirect tax on monopoly profits. Unless the social planner has...

This paper studies the effects of changes in the internal market of the European Community in a partial equilibrium model of imperfect competition with economies of scale. The model is numerically calibrated to data on ten industries and the effects of two types of policy change are simulated....

Since the 1995 publication of Obsteld and Rogoff's Redux model, there has been an outpouring of research on open-economy dynamic general equilibrium models that incorporate imperfect competition and nominal rigidities. This paper offers an interim survey of this recent literature.

In this Paper we examine the interaction between the different modes of market access commitments in services (cross-border and establishment) market structure, and regulation. In this context, we focus on the impact of improved domestic market access for a foreign service provider on a domestic...

Professional standards vary across professions and also change over time. One profession which has remained perfectionist is classical music, where the amount of practising is striking compared with other professions. Practising is a matter of increasing the reliability of ones skills rather...

In modern economies, the amount of profits distributed to shareholders is far from being negligible. We show that the way profits are distributed among agents matters for the space-economy. For example, the existence of mobile rentiers is sufficient to make the symmetric configuration unstable...

The purpose of this paper is to evaluate the relative importance of deviations from competitive behaviour, both in product and in labour markets, in the determination of sectoral employment growth in Italy during the last forty years (1951-90). This is done with the help of a two-sector...
