Download or read book High consumption Volatility written by Philippe Auffret and published by World Bank Publications. This book was released on 2003 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history of repeated external and domestic shocks has made economic insecurity a major concern across the Caribbean region. Of particular concern to all households, especially the poorest segments of the population, is the exposure to shocks that are generated by catastrophic events or natural disasters. The author shows that despite high consumption growth, the Caribbean region suffers from a high volatility of consumption that decreases household welfare. After presenting some empirical evidence that consumption volatility is higher in the Caribbean region than in the rest of the world, he makes some empirically testable inferences that help explain consumption volatility. The author develops a conceptual framework for analyzing the effects of catastrophic events on household and aggregate welfare. According to this framework, the volatility of consumption comes from production shocks that are transformed into consumption shocks mostly because of underdeveloped or ineffective risk-management mechanisms. Auffret conducts an empirical analysis of the impact of catastrophic events on 16 countries (6 from the Caribbean region and 10 from Latin America) from 1970-99 and shows that catastrophic events lead to: 1) A substantial decline in the growth of output. 2) A substantial decline in the growth of investment. 3) A more moderate decline in consumption growth (most of the decline is in private consumption, while public consumption declines moderately. 4) A worsening of the current account of the balance of payments.

This book was released on 2013-01-30 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the impact of financial depth on macroeconomic volatility using a dynamic panel analysis for 110 advanced and developing countries. We find that financial depth plays a significant role in dampening the volatility of output, consumption, and investment growth, but only up to a certain point. At very high levels, such as those observed in many advanced economies, financial depth amplifies consumption and investment volatility. We also find strong evidence that deeper financial systems serve as shock absorbers, mitigating the negative effects of real external shocks on macroeconomic volatility. This smoothing effect is particularly pronounced for consumption volatility in environments of high exposure - when trade and financial openness are high - suggesting significant gains from further financial deepening in developing countries.

Download or read book Consumption Volatility Ambiguity and Risk Premium s Time Variation written by Janis Müller and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In a consumption based asset pricing model one can calculate the volatility of (log-)consumption-growth from the expected market return and from the risk-free rate. We propose to use the difference between these estimates to measure ambiguity about consumption volatility. Using a long dataset we show that this measure explains up to 69% of post-war variation in the market risk premium.

This book was released on 2020-03-06 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic volatility remains a fact of life in Sub Saharan Africa (SSA). Household-level shocks create large consumption fluctuations, raising the incidence of poverty. Drawing on micro-level data from South Africa and Tanzania, we examine the vulnerability to shocks across household types (e.g. by education, ethnic group, and economic activity) and we quantify the impact that reducing consumption volatility would have on aggregate poverty. We then discuss coverage of consumption insurance mechanisms, including financial access and transfers. Country characteristics crucially determine which household-level shocks are most prevalent and which consumption-smoothing mechanisms are available. In Tanzania, agricultural shocks are an important source of consumption risk as two thirds of households are involved in some level of agricultural production. For South Africa, we focus on labor market risk proxied by transitions from formal employment to informal work or unemployment. We find that access to credit, when available, and government transfers can effectively mitigate labor market shocks.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book External Habit in a Production Economy written by Andrew Y. Chen and published by . This book was released on 2017 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: A standard real business cycle model with external habit and capital adjustment costs matches a long list of asset price and business cycle moments: equity, firm value, and risk-free rate volatility; the equity premium; excess return predictability; consumption growth predictability; basic moments of consumption, output, and investment; and more. The model also generates endogenous consumption volatility risk. Precautionary savings motives make consumption sensitive to shocks in bad times, leading to countercyclical volatility, even with homoskedastic technology shocks. Habit acts as countercyclical leverage, which amplifies this channel. Habit also implies high risk aversion, which amplifies the stock price response.

Download or read book Essays on Volatility Risk Premia in Asset Pricing written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis contains two essays. In the first essay, we investigate the impact of time varying volatility of consumption growth on the cross-section and time-series of equity returns. While many papers test consumption-based pricing models using the first moment of consumption growth, less is known about how the time-variation of consumption growth volatility affects asset prices. In a model with recursive preferences and unobservable conditional mean and volatility of consumption growth, the representative agent's estimates of conditional moments of consumption growth affect excess returns. Empirically, we find that estimated consumption volatility is a priced source of risk, and exposure to it predicts future returns in the cross-section. Consumption volatility is also a strong predictor of aggregate quarterly excess returns in the time-series. The estimated negative price of risk together with the evidence on equity premium predictability suggest that the elasticity of intertemporal substitution of the representative agent is greater than unity, a finding that contributes to a long standing debate in the literature. In the second essay, I present a simple model to show that if agents face binding portfolio constraints, stocks with high volatility in states of low market returns demand a premium beyond the one implied by systematic risks. Assets whose volatility positively covaries with market volatility also have high expected returns. Both effects of this idiosyncratic volatility risk premium are strongest for assets that face more binding trading restrictions. Unlike the prior empirical literature that obtains mixed results when focusing on the level of idiosyncratic volatility, I investigate the dynamic behavior of idiosyncratic volatility and find strong support for my predictions. Comovement of innovations of idiosyncratic volatility with market returns negatively predicts returns for trading restricted stocks relative to unrestricted stocks, and comovement.

Download or read book Long Run Risk Through Consumption Smoothing written by Georg Kaltenbrunner and published by . This book was released on 2011 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine how long-run consumption risk arises endogenously in a standard production economy model where the representative agent has Epstein-Zin preferences. Even when technology growth is i.i.d., optimal consumption smoothing induces highly persistent time-variation in expected consumption growth (long-run risk). This increases the price of risk when investors prefer early resolution of uncertainty, and the model can then account for the low volatility of consumption growth and the high price of risk with a low coefficient of relative risk aversion. The asset price implications of endogenous long-run risk depends crucially on the persistence of technology shocks and investors preference for the timing of resolution of uncertainty. We use the time-series of consumption growth and the cross-section of stock returns to evaluate different parameterizations of the model.

Download or read book Asset Pricing in Production Economies with Extrapolative Expectations written by David A. Hirshleifer and published by . This book was released on 2015 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introducing extrapolative bias into a standard production-based model with recursive preferences reconciles salient stylized facts about business cycles (low consumption volatility, high investment volatility relative to output) and financial markets (high equity premium, volatile stock returns, low and smooth riskfree rate) with plausible levels of risk aversion and intertemporal elasticity of substitution. Furthermore, the model captures return predictability based upon dividend yield, Q, and investment. Intuitively, extrapolative bias increases the variation in the wealth-consumption ratio, which is heavily priced under recursive preferences; adjustment costs decrease the covariance between marginal utility and asset returns. We provide empirical support for key implications of the model.

Download or read book The Volatility of Consumption in a Simple General Equilibrium Model written by Gunnar Tersman and published by International Monetary Fund. This book was released on 1992-12-01 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the volatility of consumption relative to output in the context of a simple general equilibrium model of a small open economy subject to exogenous shocks in productivity. With infinite horizons and exogenous relative prices, the model generates variance estimates that are well above what can be observed in empirical data. While finite horizons and endogenous terms of trade reduce the volatility of consumption, the model fails to generate sufficient serial correlation with respect to the consumption growth rate. If the household’s decision problem is modified to take into account durability and adjustment costs, the model does well on both dimensions.

Download or read book Global Liquidity House Prices and the Macroeconomy written by Ambrogio Cesa-Bianchi and published by International Monetary Fund. This book was released on 2015-01-29 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we first compare house price cycles in advanced and emerging economies using a new quarterly house price data set covering the period 1990-2012. We find that house prices in emerging economies grow faster, are more volatile, less persistent and less synchronized across countries than in advanced economies. We also find that they correlate with capital flows more closely than in advanced economies. We then condition the analysis on an exogenous change to a particular component of capital flows. We find that a global liquidity shock, identified by aggregating bank-to-bank cross border flows and by using the external instrumental variable approach of Stock and Watson (2012) and Mertens and Ravn (2013), has a much stronger impact on house prices and consumption in emerging markets than in advanced economies. In our empirical model, holding house prices or the exchange rate constant in response to this shock tends to dampen its effects on consumption in emerging economies.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Recent estimates of the welfare cost of consumption volatility find that it is significant in developing nations, where it may reach an equivalent of reducing consumption by 10 percent per year. Hence, examining the determinants of consumption volatility is of utmost relevance. Based on cross-country data for the period 1960-2005, the paper explains consumption volatility using three sets of variables: one refers to the volatility of income and the persistence of income shocks; the second set of variables refers to policy volatility, considering the volatility of public spending and the size of government; while the third set captures the ability of agents to smooth shocks, and includes the depth of the domestic financial markets as well as the degree of integration to international capital markets. To allow for potential endogenous regressors, in particular the volatility of fiscal policy and the size of government, the system is estimated using the instrumental variables method. The results indicate that, besides income volatility, the variables with the largest and most robust impact on consumption volatility are government size and the volatility of public spending. Results also show that deeper and more stable domestic financial markets reduce the volatility of consumption, and that more integrated financial markets to the international capital markets are associated with lower volatility of consumption.
