This article investigates what determines the price dynamics of the main cereals: barley, maize, rice and wheat. Using an extensive dataset of monthly time series covering the years 1980 - 2019, we extract four different common factors explaining the dynamics of commodity prices, exchange rates,...

We review the fuel-food price linkage models of the time series, structural, and general or partial equilibrium nature with the main attention devoted to the time series literature. Our assessment is nested in the discussion of general commodity prices co-movement on one side and in the...

We examine co-movements between biofuels and a wide range of commodities and assets in the US, Europe, and Brazil. We analyze a unique dataset of 33 commodities and relevant assets (between 2003 and 2016) which is unprecedented in the biofuels literature. We combine the minimum spanning trees...

In a seminal paper, Helpman et al. (2008) demonstrate that accounting for self-selection and firm heterogeneity is crucial for obtaining unbiased estimates in the gravity equation. In this paper, we show how this insight helps solve the trade elasticity puzzle that, hitherto, trade elasticity...

This paper explores the economic impacts of Korean unification on North and South Korea. It presents a new consistent database on macroeconomic, sectoral and trade data, and an input output table for the North Korean economy, and then incorporates it in a global intertemporal multi-sector...

The recent literature on preferential trade agreements (PTAs) emphasizes the distinction between the extensive and intensive margins. What has been missing is the distinction between tariff and non-tariff changes under PTAs. Tariff reduction is a quintessential feature of PTAs. But member...

This paper explores the impact of Korean unification on North and South Korea under the hypothetical scenario that unification takes place along the peaceful but unanticipated path similar to the experience of German reunification. Using a global dynamic intertemporal general equilibrium model,...
