This paper investigates the intertemporal relation between volatility spreads and expected returns on the aggregate stock market. We provide evidence for a signi ficantly negative link between volatility spreads and expected returns at the daily and weekly frequencies. We argue that this link is...

This working paper presents the general theory of the higher order "skew lognormal cascade distribution" as a mathematical extension of the previously proposed skew lognormal cascade distribution. In particular, the second order distribution is studied in details, which incorporates the fat...

This paper studies the macroeconomic effects of uncertainty shocks with an emphasis on the interaction between elevated uncertainty and credit market conditions when the economy is in different regimes (recessions vs. non-recessions). We use a smooth-transition factor-augmented vector...

This study investigates the trade openness and exchange rate fluctuations Nexus in Nigeria using time series data covering from1984 to 2013. The rational for this study is the realization that a viable exchange rate regime that is stable and predictable presents rich vista for economic growth...

​I​In this paper we use a New Keynesian model to explain why volatility transfer from high frequency to low frequency cycles can and did occur during the period commonly referred to as the "great moderation". The model suggests that an increase in inflation aversion and/or a reduction to a...

This paper uses a battery of calibrated and estimated structural models to determine the causal drivers of the negative correlation between output and aggregate uncertainty. We find the transmission of uncertainty shocks to output is weak, while aggregate uncertainty endogenously responds to...

This working paper is an excerpt on the recent finding of the network effect in the stock market. Specifically I summarize the three-half power law which states that the total value of the stock market is proportional to the three-half power of the number of stocks in the market. This power law...

We estimate the monthly volatility of the US economy from 1959 to 2008 by extending the factor model of Stock and Watson (1991). The volatility of the factor, which we call VOLINX, has three applications.First, it measures the changes in uncertainty in the economy. VOLINX captures the decrease...

The assumption of asymmetric and incomplete information in a standard New Keynesian model creates strong incentives for monetary policy transparency. We assume that the central bank has better information about its objectives than the private sector, and that the private sector has better...

This paper shows that the explanation of the decline in the volatility of GDP growth since the mid-eighties is not the decline in the volatility of exogenous shocks but rather a change in their propagation mechanism
