We purpose a novel explanation for the observed increase in the correlation of commodity prices over the past decade. In contrast to theories that rely on the increased influence of financial speculators, we show that price correlation can increase as a result of a decline in the interest rate....

This study examines the impact of productivity growth on the relationship between inflation and unemployment in Canada. Recently it has been suggested that higher productivity growth is responsible for a shift in the U.S. Phillips curve that occurred in the late 1990s. This paper examines...

This paper addresses the popular view that differences in financial development explain the pattern of global current account imbalances. One strain of thinking explains the net flow of capital from developing to industrial economies on the basis of the industrial economies' more advanced...

This paper assesses some of the explanations that have been put forward for the global pattern of current account imbalances that has emerged in recent years: in particular, the large U.S. current account deficit and the large surpluses of the Asian developing economies. Based on the approach...

Empirical work regarding Intertemporal Current Account (ICA) models has centered around two distinct testing methodologies, present value tests and a productivity shock approach as formulated in Glick and Rogoff (1995). In previous work, Gruber (2001), I have tested an ICA model that allows for...

Global and U.S. trade declined dramatically in the wake of the global financial crisis in late 2008 and early 2009. The subsequent recovery in trade, while vigorous at first, gradually lost momentum in 2010. Against this backdrop, this paper explores the prospects for global and U.S. trade in...

We examine the impact of fiscal positions, both the level of debt and the fiscal balance, on long-term government bond yields in the OECD. In order to control for the endogenity of fiscal positions to the business cycle we utilize forward projections of fiscal positions from the OECD's Economic...

This paper analyzes the quality of VAR-based procedures for estimating the response of the economy to a shock. We focus on two key issues. First, do VAR-based confidence intervals accurately reflect the actual degree of sampling uncertainty associated with impulse response functions? Second,...

We provide empirical evidence that a positive shock to technology drives up per capita hours worked, consumption, investment, average productivity and output . This evidence contrasts sharply with the results reported in a large and growing literature that argues, on the basis of aggregate data,...

A common view in the literature is that the effect of energy price shocks on macroeconomic aggregates is asymmetric in energy price increases and decreases. We show that widely used asymmetric vector autoregressive models of the transmission of energy price shocks are misspecified, resulting in...
