We offer retrospective and prospective assessments of the Diebold-Yilmaz connectedness research program, combined with personal recollections of its development. Its centerpiece in many respects is Diebold and Yilmaz (2014), around which our discussion is organized.

Imposing cointegration on a forecasting system, if cointegration is present, is believed to improve long-horizon forecasts. Contrary to this belief, at long horizons nothing is lost by ignoring cointegration when the forecasts are evaluated using standard multivariate forecast accuracy measures....

This paper extends the partial (PE) and general equilibrium (GE) analyses of Nash and Stackelberg optimum export taxes to a multicountry framework, using a computable general equilibrium (CGE) model of the global cocoa market. There are several important results to report. First, depending on...

This paper uses the variance-ratio-based multiple comparison test and Richardson-Smith's Wald test procedures to test for martingale property of daily exchange rates of seven major currencies vis-a-vis US dollar. To allow for the possibility that exchange rates are not governed by a single...

We obtain measures of demand and supply shock spillovers across the U.S. manufacturing industries using monthly data on industrial production (1976-2022) and producer prices (1947-2022). Analyzing the spillovers/connectedness measures and the input-output linkages, we find strong evidence that...
