A representative-consumer model with Epstein-Zin-Weil preferences and i.i.d. shocks, including rare disasters, accords with key asset-pricing observations. If the coefficient of relative risk aversion equals 3-4, the model accords with observed equity premia and risk-free real interest rates. If the intertemporal elasticity of substitution is greater than one, an increase in uncertainty lowers the price-dividend ratio for equity, whereas a rise in the expected growth rate raises this ratio. In a model with endogenous saving, more uncertainty lowers the saving ratio (because substitution effects dominate). The match with major features of asset pricing suggests that the model is a reasonable candidate for assessing the welfare cost of aggregate consumption uncertainty. In the baseline simulation, the welfare cost of disaster risk is large -- society would be willing to lower real GDP by as much as 20% each year to eliminate the small chance of major economic collapses. The welfare cost from usual economic fluctuations is much smaller, though still important, corresponding to lowering GDP by around 1.5% each year.

"Satisfactory calculations of the welfare cost of aggregate consumption uncertainty require a framework that replicates major features of asset prices and returns, such as the high equity premium and low risk-free rate. A Lucas-tree model with rare but large disasters is such a framework. In a baseline simulation, the welfare cost of disaster risk is large -- society would be willing to lower real GDP by about 20% each year to eliminate all disaster risk, including wars. In contrast, the welfare cost from usual economic fluctuations is much smaller, though still important -- corresponding to lowering GDP by around 1.5% each year"--National Bureau of Economic Research web site.

Although the threat of rare economic disasters can have large effect on asset prices, difficulty in inference regarding both their likelihood and severity provides the potential for disagreements among investors. Such disagreements lead investors to insure each other against the types of disasters each one fears the most. Due to the highly nonlinear relationship between consumption losses in a disaster and the risk premium, a small amount of risk sharing can significantly attenuate the effect that disaster risk has on the equity premium. We characterize the sensitivity of risk premium to wealth distribution analytically. Our model shows that time variation in the wealth distribution and the amount of disagreement across agents can both lead to significant variation in disaster risk premium. It also highlights the conditions under which disaster risk premium will be large, namely when disagreement across agents is small or when the wealth distribution is highly concentrated in agents fearful of disasters. Finally, the model predicts an inverse U-shaped relationship between the equity premium and the size of the disaster insurance market -- National Bureau of Economic Research web site.

Winner of the prestigious Paul A. Samuelson Award for scholarly writing on lifelong financial security, John Cochrane's Asset Pricing now appears in a revised edition that unifies and brings the science of asset pricing up to date for advanced students and professionals. Cochrane traces the pricing of all assets back to a single idea--price equals expected discounted payoff--that captures the macro-economic risks underlying each security's value. By using a single, stochastic discount factor rather than a separate set of tricks for each asset class, Cochrane builds a unified account of modern asset pricing. He presents applications to stocks, bonds, and options. Each model--consumption based, CAPM, multifactor, term structure, and option pricing--is derived as a different specification of the discounted factor. The discount factor framework also leads to a state-space geometry for mean-variance frontiers and asset pricing models. It puts payoffs in different states of nature on the axes rather than mean and variance of return, leading to a new and conveniently linear geometrical representation of asset pricing ideas. Cochrane approaches empirical work with the Generalized Method of Moments, which studies sample average prices and discounted payoffs to determine whether price does equal expected discounted payoff. He translates between the discount factor, GMM, and state-space language and the beta, mean-variance, and regression language common in empirical work and earlier theory. The book also includes a review of recent empirical work on return predictability, value and other puzzles in the cross section, and equity premium puzzles and their resolution. Written to be a summary for academics and professionals as well as a textbook, this book condenses and advances recent scholarship in financial economics.

In recent decades, the financial markets have experienced various crises, shocks and disruptive events, driving high levels of volatility. This volatility is too strong to be fully justified simply by changes in fundamentals. This volume discusses these highly relevant issues with special focus on asset pricing and behavioral finance. Financial price assets of the 2020s appear to be driven by various attractors in addition to fundamentals, and there is no doubt that investor emotions, market sentiment, the news, and external factors such as uncertainty all play a key role. This has been clearly observed in recent years, especially during the ongoing coronavirus pandemic that has changed the common perception of the way financial markets work.

Today all would agree that Mexico and the United States have never been closer--that the fates of the two republics are intertwined. Mexico has become an intimate part of life in almost every community in the United States, through immigration, imported produce, business ties, or illegal drugs. It is less a neighbor than a sibling; no matter what our differences, it is intricately a part of our existence. In the fully updated second edition of Mexico: What Everyone Needs to Know(R), Roderic Ai Camp gives readers the most essential information about our sister republic to the south. Camp organizes chapters around major themes--security and violence, economic development, foreign relations, the colonial heritage, and more. He asks questions that take us beyond the headlines: Why does Mexico have so much drug violence? What was the impact of the North American Free Trade Agreement? How democratic is Mexico? Who were Benito Juarez and Pancho Villa? What is the PRI (the Institutional Revolutionary Party)? The answers are sometimes surprising. Despite ratification of NAFTA, for example, Mexico has fallen behind Brazil and Chile in economic growth and rates of poverty. Camp explains that lack of labor flexibility, along with low levels of transparency and high levels of corruption, make Mexico less competitive than some other Latin American countries. The drug trade, of course, enhances corruption and feeds on poverty; approximately 450,000 Mexicans now work in this sector. Brisk, clear, and informed, Mexico: What Everyone Needs To Know(R) offers a valuable primer for anyone interested in the past, present, and future of our neighbor to the South. Links to video interviews with prominent Mexicans appear throughout the text.

Using a dynamic stochastic general equilibrium model, we study the channels through which natural disaster shocks affect macroeconomic outcomes and welfare in disaster-prone countries. We solve the model using Taylor projection, a solution method that is shown to deal effectively with high-impact weather shocks calibrated in accordance to empirical evidence. We find large and persistent effects of weather shocks that significantly impact the income convergence path of disaster-prone countries. Relative to non-disaster-prone countries, on average, these shocks cause a welfare loss equivalent to a permanent fall in consumption of 1.6 percent. Welfare gains to countries that self-finance investments in resilient public infrastructure are found to be negligible, and international aid has to be sizable to achieve significant welfare gains. In addition, it is more cost-effective for donors to contribute to the financing of resilience before the realization of disasters, rather than disbursing aid after their realization.
