We construct a new database which covers production and trade in 136 primary commodities and 24 manufacturing and service sectors for 145 countries. Using this new more granular data, we estimate spillover effects from plausible trade fragmentation scenarios in a new multi-country, multi-sector,...

The amount of cooperation needed to improve the welfare of signatories of International Environmental Agreements (IEAs), in the presence of market imperfections, depends on the characteristics of pollution. In a dynamic model, the conventional wisdom on the effect of free-riding needs to be...

I present a model of two quantity-setting firms, each producing two goods in a different country, but enjoying a competitive advantage in only one of them. An international cartel can either shut down trade and manufacture both goods domestically or foreclose the inefficient plant and import the...

We study trade policy in a two-sector Krugman-type trade model with home market effects. We allow for three different instruments: tariffs, export taxes and production subsidies. For each instrument, we consider unilateral trade policy without retaliation. We find - contrary to the results of...

We study trade policy in a two-sector Krugman (1980) trade model, allowing for production, import and export subsidies/taxes. We consider non-cooperative and cooperative trade policy, first for each individual instrument and then for the situation where all instruments can be set simultaneously,...

In this paper, I explore the aggregate effects of trade restrictions in a two-country, dynamic, stochastic, general equilibrium (DSGE) model with firm selection and variable adjustment of markup. As a response to the trade collapse in the global crisis of 2008 and 2009, trade restrictions have...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....

The phrase financial contagion draws on a concept whose root meaning lies in the field of epidemiology. Like almost all metaphors, this one has the power to illuminate and to mislead. Its referent is the spread of financial distress from one firm, market, asset class, nation, or geographical...

We study trade policy in a two-sector Krugman-type trade model with home market effects. We conduct a general analysis allowing for three different instruments: tariffs, export taxes and production subsidies. For each instrument, we consider unilateral trade policy without retaliation. When...
