Theory suggests that uninsurable income risk induces individuals to accumulate assets as a precautionary reserve of value. Most assets, however, bear rate of return risk, that can be diversified only if every asset is traded by a large number of individuals and arbitrage is frictionless. Using...

A standard result of optimal debt management models is that in a world of complete markets, where policymakers can make credible announcements, the maturity structure of government debt is totally irrelevant. This paper investigates the role of debt maturity in a very simple context in which...

This paper proposes a test for the cost-based explanation of non-participation, by estimating a lower bound to the forgone gains of incomplete portfolios; these are in turn a lower bound to the costs that could rationalize non-participation in financial markets: high bounds would imply...

This paper builds a unifying framework based on the theory of intertemporal consumption choices that brings together the limited participation-based explanation of the C-CAPM poor empirical performance and the transaction costs-based explanation of incomplete portfolios. Using the implications...

We propose a theory-based approach to testing the presence of the 'home market effect' in a multi-country world. Our framework extends Krugman's (1980, Am. Econ. Rev. 70(5), 950-959) model, in which the appeal of a country as a production site depends on both the relative size of its domestic...

We develop a multi-country Dixit-Stiglitz trade model and analyze how industry location and welfare respond to changes in: (i) transport frictions (e.g., infrastructure, transportation technology); and (ii) non-transport frictions (e.g., tariffs, standards and regulations). We show that changes...

The European Emissions Trading Scheme (ETS) is a cap and trade system to curb CO2 emissions. It has caused both direct costs (CO2 allowances) and indirect costs (higher electricity prices) to energy-intensive industries. Moreover, as there is no global CO2 agreement, the ETS could distort the...

We study how aggregate volatility is influenced by the propagation of idiosyncratic shocks across firms through the network of ownership relations. We use detailed data on cross-holdings as well as the relevant balance sheet information for almost the entire universe of Italian limited liability...

We assess the impact of low-skilled immigration on capital intensity. We first present a model characterized by frictions in the labor market and firms' asymmetric information on workers' skills and show that firms can react to the immigration-induced reduction of their workforce's skill level...
