We conducted a study analyzing the impact of productivity shocks on equity returns in the U.S. economy from Q1 1960 to Q1 2022 using an RBC DSGE model. Our results suggest that while initial productivity shocks lead to higher equity returns, this effect fades within eight quarters. Nonetheless, such shocks can still provide valuable signals for investors to strategically allocate their investments in sectors that may benefit the most. Our study also found that the responses of key macroeconomic variables, including real GDP, are consistent with those observed in other calibration based DSGE models of the U.S. in previous research.

Using a production based asset pricing framework in continuous time, this paper examines how exogenous productivity and wage rate shocks are transmitted to equilibrium asset prices. More specifically, our equilibrium pricing model suggests that productivity and wage rate shocks are perhaps the real cause for the observed time varying behavior of expected asset returns. A significant implication of the model is that ex-post asset returns in one period are shown to be related to the investment/output ratio in the same period (negative correlation) as well as the forecast of the growth rate of output in the next period (positive correlation).

Overly optimistic expectations concerning productivity and consequent downward revisions are commonly viewed as a key determinant of U.S. investment during the boom-bust cycle of 1995-2003. This view is formalized and evaluated in a general equilibrium model with news shocks about future productivity and preferences for financial wealth. The model generates a boom-bust cycle in response to good news that is not realized. A method is devised to estimate "the productivity prospects": a series that captures the effects of news shocks on economic decisions. The estimated series rises during the boom, falls during the recession and helps forecast future productivity shocks at several horizons. The model's predictions for sample paths of hours worked, output, investment, consumption, wages and stock prices are largely in conformity with U.S. data. The model therefore offers a possible solution to several puzzles identified in the literature regarding the 1990's boom and the 2001 recession.
In this paper, we examine the effects of money supply, portfolio, aggregate spending, and aggregate supply shocks on real US stock prices in a structural vector autoregression framework using quarterly data for the period of 1947:1-2011:3. Overall, the empirical results indicate that each macro shock has important effects on real stock prices, with aggregate supply shocks playing an important role, besides portfolio shocks. The real stock price impulse responses to the various macro shocks conform to the standard present-value equity valuation model, and hence, our identification based on long-run restrictions can be viewed as appropriate. An historical decomposition indicates that the decline in the real stock prices during the "Great Recession" is mainly due to a slowdown in US productivity, after investors had decided to carry out exogenous portfolio shifts out of stocks. In general, we conclude that during the "Great Recession" the declining stock prices resu...

Macroeconomic conditions are known to affect risks factors and thereby influence asset returns within a given economy. We explore this link in a global setting. Given the dominant role the U.S. economy plays in the global economic environment, U.S. Macro economic shocks are expected to affect asset returns in other countries. The impact should be more pronounced in the developed economies where the U.S. is a large trading and capital-flows partner. Our results shows that residual returns and conditional volatilities in major developed economies are significantly impacted by US macroeconomic surprises. We identify U.S. macro economic shocks that have spillover impact on global asset returns over and above those transmitted through equity market returns. While return levels are significantly influenced by productivity and retail sales surprises, return conditional volatilities are mainly influenced by inflation, personal income, industrial production, leading indicators, and gross domestic product surprises.

This paper estimates a DSGE model in which stock price fluctuations exert a direct impact on the demand side of the economy. This is due to the financial wealth effect arising when agents' effective decision horizon is finite. We estimate this otherwise standard new-Keynesian model with Bayesian techniques in order to fit the U.S. facts in the sample 1985Q1-2006Q4. We find a significant role for the stock price "regressor" in the IS curve, and estimate the effective decision horizon to be about 11 quarters. Stock prices do not appear to have entered a Taylor-type rule as an independent regressor. However, a 5% unexpected increase of the stock price gap triggers an on impact interest rate hike of 16 basis points. When looking at the opposite causal link, we find that a monetary policy tightening leading to a 28 basis points upward jump of the policy rate opens a negative stock price gap equal to 42 basis points. In terms of explained variance, stock price shocks appear to explain a fair bit of the variability of the forecast error of the nominal interest rate. By contrast, stock prices are mainly driven by their own shocks along with demand shocks.

This paper develops a neoclassical general equilibrium model to study the endogenous response of the stock market and the term structure of real interest rates in the face of a number of macroeconomic shocks believed to be important in the 1980s. An exogenous decline in savings, a debt-financed fiscal expansion, an increase in investment subsidy and an anticipation of higher productivity growth are found to have contrasting effects on the value of the stock market and the behaviour of the term structure of real interest rates in the model closed economy.

This paper examines the relation between stock returns and unexpected changes in nominal and real interest rates and inflation for the US stock market. With the exception of Sweeney and Warga (1986), we are the first to examine this relation in detail by breaking the results down from the US stock market level to sector, sub-sector and to individual industries as the ability of different industries to absorb unexpected changes in interest rates and inflation can vary by industry and by time period. Unlike Sweeney and Warga (1986), we also look for stability in the relations by examining them by sector during contraction and expansion sub-periods throughout a long time period, from September 1989 to February 2014. While most significant relations are conventionally negative, some are consistently positive. Specifically, we find that Integrated Oil and Gas, Commercial Services and Supplies and Diversified Metals and Mining have a consistent significant positive relation between stock ...

This paper investigates the interactions between stock market fluctuations and monetary policy within a DSGE model for the U.S. economy. First, we design a framework in which fluctuations in households financial wealth are allowed -but not necessarily required -to exert an impact on current consumption. This is due to the interaction, in the financial markets, of long-time traders holding wealth accumulated over time with newcomers holding no wealth at all. Importantly, we introduce nominal wage stickiness to induce pro-cyclicality in real dividends. Additional nominal and real frictions are modeled to capture the pervasive macroeconomic persistence of the observables employed to estimate our model. We fit our model to post-WWII U.S. data, and report three main results. First, the data strongly support a significant role of stock prices in affecting real activity and the business cycle. Second, our estimates also identify a significant and counteractive response of the Fed to stock-price fluctuations. Third, we derive from our model a microfounded measure of financial slack, the "stock-price gap", which we then contrast to alternative ones, currently used in empirical studies, to assess the properties of the latter to capture the dynamic and cyclical implications of our DSGE model. The behavior of our "stock-price gap" is consistent with the episodes of stock-market booms and busts occurred in the post-WWII, as reported by independent analyses, and closely correlates with the current financial meltdown. Typically employed proxies of financial slack such as detrended log-indexes or growth rates show limited capabilities of capturing the implications of our model-consistent index of financial stress. Cyclical properties of the model as well as counterfactuals regarding shocks to our measure of financial slackness and monetary policy shocks are also proposed.
