Commodity price gains: speculation vs. fundamentals
Commodities of all sorts have risen in price over the past few years. Some say that the prices reflect a bubble, driven by low interest rates and excessive speculation. Others say the price gains can be fully explained by supply and demand.

Why health care matters and the current debt does not
All of the attention given to raising the debt ceiling this past summer might lead some to believe that spending by the federal government only recently became unsustainable. Hardly. We've been on this path a long time.

Threshold adjustment in deviations from the law of one price
Using self-exciting threshold autoregressive models, we explore the validity of the law of one price (LOOP) for sixteen sectors in nine European countries. We and strong evidence of nonlinear mean reversion in deviations from the LOOP and highlight the importance of modelling the real exchange rate in a nonlinear fashion in an attempt to measure speeds of real exchange rate adjustment. Using the US dollar as a reference currency, the half-lives of sectoral real exchange rates shocks, calculated by Monte Carlo integration, imply much faster adjustment than the consensus half-life estimates of ...

Export market diversification and productivity improvements: theory and evidence from Argentinean firms
This paper examines the relationship between trade and investment in technology adoption when firms face demand uncertainty. Our model predicts that, for a given overall market size, exporting to several countries reduces firms' demand uncertainty and, hence, raises incentives to invest in productivity improvements. The effects of diversification are heterogeneous across firms: An additional foreign market matters more for firms exporting to fewer destinations. We test the proposed theory using a large sample of Argentinean manufacturing exporters. The predictions of the model find strong ...

Pricing-to-market and business cycle synchronization
There is substantial evidence that countries or regions with stronger trade linkages tend to have business cycles which are more synchronized. However, the standard international business cycle framework cannot replicate this finding. In this paper we study a multiple- country model of international trade with imperfect competition and variable markups and embed it into a real business cycle framework by including aggregate technology shocks and allowing for variable labor supply. The model is successful at replicating the empirical relation between trade and business cycle synchronization. ...

Speculation in the oil market
The run-up in oil prices after 2004 coincided with a growing flow of investment to commodity markets and an increased price comovement between different commodities. We analyze whether speculation in the oil market played a key role in driving this salient empirical pattern. We identify oil shocks from a large dataset using a factor-augmented autoregressive (FAVAR) model. We analyze the role of speculation in comparison to supply and demand forces as drivers of oil prices. The main results are as follows: (i) While global demand shocks account for the largest share of oil price fluctuations, ...
