Unemployment Duration Variance Decomposition a la ABS


Book Description

In a recent paper, Alvarez, Borovickova, and Shimer (2014) revisit the analysis of the determinants of unemployment duration by proposing a new method (the ABS method hereafter) that directly estimates the importance of each component and implementing it using precise information on unemployment spells from social security administrative data for Austria. In this paper, we apply the ABS method to social security administrative data for Spain with the objective of comparing these two very different labor markets as well as Spain along the business cycle. Administrative data have many advantages compared to Labor Force Survey data, but the incomplete nature of the data needs to be addressed in order to use the data for unemployment analysis (e.g., unemployed workers that runout of unemployment insurance have no labor market status in the data). The degree and nature of such incompleteness are country-specific and are particularly important in Spain. Following Lafuente (2018), we approach the matter of data incompleteness in a systematic way by using information from the Spanish LFS data as well as institutional information. We hope that our approach will provide a useful way to apply the ABS method in other countries. Our findings are as follows: (i) The aggregate component is clearly the most important one, followed by heterogeneity and duration dependence, which are roughly comparable. (ii) The relative importance of each component and, in particular, duration dependence is quite similar in Austria and Spain, especially when minimizing the effect of fixed-term contracts in Spain. Similarly, we do not find big differences in the relative contribution of the different components along the business cycle in Spain. (iii) These comparisons suggest that statistical discrimination due to dynamic sample selection does not seem to be the main driver of duration dependence.

The Roaring Nineties


Book Description

The positive social benefits of low unemployment are many—it helps to reduce poverty and crime and fosters more stable families and communities. Yet conventional wisdom—born of the stagflation of the 1970s—holds that sustained low unemployment rates run the risk of triggering inflation. The last five years of the 1990s—in which unemployment plummeted and inflation remained low—called this conventional wisdom into question. The Roaring Nineties provides a thorough review of the exceptional economic performance of the late 1990s and asks whether it was due to a lucky combination of economic circumstances or whether the new economy has somehow wrought a lasting change in the inflation-safe rate of unemployment. Led by distinguished economists Alan Krueger and Robert Solow, a roster of twenty-six respected economic experts analyzes the micro- and macroeconomic factors that led to the unexpected coupling of low unemployment and low inflation. The more macroeconomically oriented chapters clearly point to a reduction in the inflation-safe rate of unemployment. Laurence Ball and Robert Moffitt see the slow adjustment of workers' wage aspirations in the wake of rising productivity as a key factor in keeping inflation at bay. And Alan Blinder and Janet Yellen credit sound monetary policy by the Federal Reserve Board with making the best of fortunate circumstances, such as lower energy costs, a strong dollar, and a booming stock market. Other chapters in The Roaring Nineties examine how the interaction between macroeconomic and labor market conditions helped sustain high employment growth and low inflation. Giuseppe Bertola, Francine Blau, and Lawrence M. Kahn demonstrate how greater flexibility in the U.S. labor market generated more jobs in this country than in Europe, but at the expense of greater earnings inequality. David Ellwood examines the burgeoning shortage of skilled workers, and suggests policies—such as tax credits for businesses that provide on-the-job-training—to address the problem. And James Hines, Hilary Hoynes, and Alan Krueger elaborate the benefits of sustained low unemployment, including budget surpluses that can finance public infrastructure and social welfare benefits—a perspective often lost in the concern over higher inflation rates. While none of these analyses promise that the good times of the 1990s will last forever, The Roaring Nineties provides a unique analysis of recent economic history, demonstrating how the nation capitalized on a lucky confluence of economic factors, helping to create the longest peacetime boom in American history.

Optimal Unemployment Insurance


Book Description

Designing a good unemployment insurance scheme is a delicate matter. In a system with no or little insurance, households may be subject to a high income risk, whereas excessively generous unemployment insurance systems are known to lead to high unemployment rates and are costly both from a fiscal perspective and for society as a whole. Andreas Pollak investigates what an optimal unemployment insurance system would look like, i.e. a system that constitutes the best possible compromise between income security and incentives to work. Using theoretical economic models and complex numerical simulations, he studies the effects of benefit levels and payment durations on unemployment and welfare. As the models allow for considerable heterogeneity of households, including a history-dependent labor productivity, it is possible to analyze how certain policies affect individuals in a specific age, wealth or skill group. The most important aspect of an unemployment insurance system turns out to be the benefits paid to the long-term unemployed. If this parameter is chosen too high, a large number of households may get caught in a long spell of unemployment with little chance of finding work again. Based on the predictions in these models, the so-called "Hartz IV" labor market reform recently adopted in Germany should have highly favorable effects on the unemployment rates and welfare in the long run.




Forecasting: principles and practice


Book Description

Forecasting is required in many situations. Stocking an inventory may require forecasts of demand months in advance. Telecommunication routing requires traffic forecasts a few minutes ahead. Whatever the circumstances or time horizons involved, forecasting is an important aid in effective and efficient planning. This textbook provides a comprehensive introduction to forecasting methods and presents enough information about each method for readers to use them sensibly.




Strategic Asset Allocation


Book Description

Academic finance has had a remarkable impact on many financial services. Yet long-term investors have received curiously little guidance from academic financial economists. Mean-variance analysis, developed almost fifty years ago, has provided a basic paradigm for portfolio choice. This approach usefully emphasizes the ability of diversification to reduce risk, but it ignores several critically important factors. Most notably, the analysis is static; it assumes that investors care only about risks to wealth one period ahead. However, many investors—-both individuals and institutions such as charitable foundations or universities—-seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption. At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks. This should be important in practice because there is a great deal of empirical evidence that investment opportunities—-both interest rates and risk premia on bonds and stocks—-vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models. This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows how labor income influences portfolio choice. These results shed new light on the rules of thumb used by financial planners. The book explains recent advances in both analytical and numerical methods, and shows how they can be used to understand the portfolio choice problems of long-term investors.
