This paper tests for fractional roots in the futures prices for selected commodities, foreign currencies, and stock indexes. The fractional testing method is the spectral regression method suggested by Geweke and Porter-Hudak (1983). The empirical results suggest the presence of a fractional...

We present an empirical investigation of a recently suggested but untested proposition that exchange rate volatility can have an impact on both the volume and variability of trade flows, considering a broad set of countries' bilateral real trade flows over the period 1980-1998. We generate...

This paper studies of credit rating agency (CRA) downgrade announcements on the value of the Euro and the yields of French, Italian, German and Spanish long-term sovereign bonds during the culmination of the Eurozone debt crisis in 2011-2012. The employed GARCH models show that CRA downgrade...

This presentation discusses how the tasks involved with carrying out a sizable research project, involving panel data at both monthly and daily frequencies, could be efficiently managed by making use of built-in and user-contributed features of Stata. The project entails the construction of a...

We discuss instrumental variables (IV) estimation in the broader context of the generalized method of moments (GMM), and describe an extended IV estimation routine that provides GMM estimates as well as additional diagnostic tests. Stand-alone test procedures for heteroskedasticity,...

In this paper we empirically investigate the link between bank lending and macroeconomic uncertainty using annual and quarterly U.S. bank level data. For both data sets, we show that as macroeconomic uncertainty increases, captured by an increase in the variability of industrial production or...

This paper empirically investigates whether changes in macroeconomic volatility affect the effcient allocation of non-financial firms' liquid assets. We argue that higher uncertainty will hamper managers' ability to accurately predict firm-specific information and induce them to implement...

This paper investigates whether variations in macroeconomic uncertainty distort banks' allocation of loanable funds by affecting the predictability of banks' returns from lending. Low levels of macroeconomic uncertainty will allow bankers to base their lending decisions on more accurate...
