We propose a simulation-based procedure for evaluating approximation accuracy of numerical solutions of general equilibrium models with heterogeneous agents. We measure the approximation accuracy by the magnitude of the welfare loss suffered by agents from following sub-optimal policies. Our...

I develop an analytical general-equilibrium model to explain economic sources of business-cycle pattern of aggregate stock market returns. With concave production functions and capital accumulation, a technology shock has a pro-cyclical direct effect and a counter-cyclical indirect effect on...

We show that dynamic investment portfolio asset allocation based on secular market cycles outperforms a buy-and-hold portfolio of equities and outperforms a buy-and-hold portfolio of gold over long periods. An objective definition of secular market enables identification of an appropriate...

We provide strong evidence of persistent cyclical variation in the sensitivity of stock returns to macroeconomic news announcement (MNA) surprises. When the economy is significantly below trend (output gap is large and negative) and interest rates are not expected to go up, the stock return...

We document a countercyclical sensitivity of the stock market to major macroeconomic news announcements. Stock prices react more to (either good or bad) announcement surprises when the economy is below its potential trend with the expectation of easing policy. Based on comprehensive regression...

We develop a general equilibrium model that jointly explains important features of the term structure of equity: (i) a negative unconditional term premium, (ii) countercyclical term premia, (iii) procyclical equity yields, (iv) premia to value and growth claims respectively increasing and...

We study the effect of economic uncertainty exposure (EUE) on cross-sectional return differentiating the mispricing from ambiguity-premium effects. Conditional on a common mispricing index, we find that EUE induces disagreement which amplifies mispricing. The highest EUE quintile produces an...

Climate change is already a systemic risk to the global economy. While there is a large body of literature documenting potential economic consequences, there is scarce research on the link between climate change and sovereign risk. This paper therefore investigates the impact of climate change...

We test the hypothesis that retail investors' attraction to lottery stocks induces overvaluation, and is amplified by high attention and social interactions. The lottery premium (negative abnormal returns) is stronger for high-retail-ownership stocks—especially those that also have high...

We produce novel empirical evidence on the relevance of temperature volatility shocks for the dynamics of macro aggregates and asset prices. Using two centuries of UK temperature data, we document that the relationship between temperature volatility and the macroeconomy varies over time. First,...
