This analysis employs cointegration methods and semiparametric regression in order to assess the integration of maize markets and the factors determining national and cross-national transmission of price signals in Sub-Saharan Africa. We use a rich dataset of 16 series of wholesale maize prices...

I offer a selective review of discounting and climate policy. Analytic and numerical models show that different assumptions greatly change the degree to which decisions about climate policy depend on the discount rate. I discuss a claim that standard models exaggerate the current generation’s...

This paper studies the relationship between export policy and food prices. We show that, when individuals are loss averse, food exporters may use trade policy to shield the domestic economy from large price shocks. This creates a complementarity between the price of food in international markets...

This article presents a Ricardian model of trade with learning-by-doing to study the effect of barriers to trade in products with low growth potential on the long-run economic growth. The model shows that, when elasticity of demand for the product with a lower learning potential is lower than...

The SSM is a proposal from the G-33 Group in the Doha Round negotiations in which developing countries would be allowed to use contingent tariffs to control import surges of food commodities and/or downward spikes in their border prices. The principal objective is to safeguard the livelihood...

This paper offers a new theoretical approach to urban squatting, reflecting the view that squatters and formal residents compete for land within a city. The key implication of this view is that squatters “squeeze” the formal market, raising the price paid by formal residents. The squatter...

Excessive preoccupation for self-image has been pointed out as an essential factor explaining food disorders. This paper draws upon Akerlof and Kranton (2000) to model how ’self-image’ and others’ appearances influence health related behaviours. We estimate the influence of ’peers’...

Existing theories of a firm’s optimal capital structure seem to fail in explaining why many healthy and profitable firms rely heavily on equity financing, even though benefits associated with debt (like tax shields) appear to be high and the bankruptcy risk low. This holds in particular for...

When trading, firms choose between different payment contracts. As shown theoretically in Schmidt-Eisenlohr (forthcoming), this allows firms in international trade to optimally trade-off differences in financing costs and enforcement across countries. This paper provides evidence from a large...

This paper examines the impact of thin capitalization rules that limit the tax deductibility of interest on the capital structure of the foreign affiliates of US multinationals. We construct a new data set on thin capitalization rules in 54 countries for the period 1982-2004. Using confidential...
