Over the years, there emerged two key policy differences between Europe and America, both welfare and migration-states. The former has more generous welfare state and more liberal migration policies than the latter. In this paper we attempt to provide a political-economy explanation for these...

The informativeness principle demonstrates qualitative benefits to increasing signal precision. However, it is difficult to quantify these benefits -- and compare them against the costs of precision -- since we typically cannot solve for the optimal contract and analyze how it changes with...

This paper evaluates the global welfare impact of observed levels of migration using a quantitative multi-sector model of the world economy calibrated to aggregate and firm-level data. Our framework features cross-country labor productivity difference, international trade, remittances, and a...

Following the financial crisis of 2008/9, there has been renewed interest in what Greenwald and Stiglitz dubbed ‘pecuniary externalities’. Two that affect borrowers and lenders balance sheets in pro-cyclical fashion are described, along with measures that might help curb their destabilising...

We study a largely neglected channel through which government expenditures boost private consumption. We set up a lifecycle model in which households are subject to health shocks. We estimate a negative impact of public health care on household consumption dispersion, wealth and saving....

We consider a simple trading relationship between an expectation-based loss-averse buyer and profit-maximizing sellers. When writing a long-term contract the parties have to rely on renegotiations in order to ensure materially efficient trade ex post. The type of the concluded long-term contract...

This paper combines income tax returns with Flow of Funds data to estimate the distribution of household wealth in the United States since 1913. We estimate wealth by capitalizing the incomes reported by individual taxpayers, accounting for assets that do not generate taxable income. We...

A quantitative investigation of financial intermediation in the U.S. over the past 130 years yields the following results : (i) the finance industry’s share of GDP is high in the 1920s, low in the 1950s and 1960s, and high again in the 1990s and 2000s; (ii) most of these variations can be...

Banks’ behaviour can be influenced by both monetary policy and regulatory capital requirements. This paper explores the interaction between these two policy tools in promoting better lending decisions by banks. We develop and calibrate a model of bank lending to examine what an optimal...

Using a spatial competition framework with three ex ante identical firms, we study the effects of a horizontal merger on quality, price and welfare. The merging firms always reduce quality. They also increase prices if demand responsiveness to quality is sufficiently low. The non-merging firm,...
