Sustainability: Suspicions Concerning Attainability, with Particular Reference to the Pacific

Sustainability and unsustainability are frequently deployed in discussions of intended, predicted and observed changes occurring in or impacting on Pacific islands societies. Local communities often have their own distinctive understanding of the natural environment. Their concern for sustainability frequently extends further afield – to languages, cultures, and other aspects of life. International agreements and the constitutions of a number of Pacific islands countries address relevant issues. Constitutional government in the region has been remarkably sustained. Sustainable development has diverse dimensions and can be controversial. Climate change and rising sea-levels threaten the very survival of low-lying islands. Harvesting of non-renewable resources raises particular issues. Pacific islands studies have made significant contributions to scientific knowledge and human understanding of issues and processes of wider, even global importance

Is Business Cycle Volatility Costly? Evidence from Surveys of Subjective Wellbeing

This paper analyzes the effects of business cycle volatility on measures of subjective well-being, including self-reported happiness and life satisfaction. I find robust evidence that high inflation and, to a greater extent, unemployment lower perceived well-being. Greater macroeconomic volatility also undermines well-being. These effects are moderate but important: eliminating unemployment volatility would raise well-being by an amount roughly equal to that from lowering the average level of unemployment by a quarter of a percentage point. The effects of inflation volatility on well-being are less easy to detect and are likely smaller.

Did Unilateral Divorce Laws Raise Divorce Rates? A Reconciliation and New Results

Application of the Coase Theorem to marital bargaining suggests that shifting from a consent divorce regime to no-fault unilateral divorce laws should not affect divorce rates. Each iteration of the empirical literature examining the evolution of divorce rates across US states has yielded different conclusions about the effects of divorce law liberalization. I show that these results reflect a failure to jointly consider both the political endogeneity of these divorce laws and the dynamic response of divorce rates to a shock to the political regime. Taking explicit account of the dynamic response of divorce rates to the policy shock, I find that liberalized divorce laws caused a discernible rise in divorce rates for about a decade, but that this increase was substantially reversed over the next decade. That said, this increase explains very little of the rise in the divorce rate over the past half century. Both administrative data on the flow of new divorces, and measures of the stock of divorcees from the census support this conclusion. These results are suggestive of spouses bargaining within marriage, with an eye to their partner's divorce threat.

Diagnosing Discrimination: Stock Returns and CEO Gender

A vast labor literature has found evidence of a %u201Cglass ceiling%u201D, whereby women are under-represented among senior management. A key question remains the extent to which this reflects unobserved differences in productivity, preferences, prejudice, or systematically biased beliefs about the ability of female managers. Disentangling these theories would require data on productivity, on the preferences of those who interact with managers, and on perceptions of productivity. Financial markets provide continuous measures of the market%u2019s perception of the value of firms, taking account of the beliefs of market participants about the ability of men and women in senior management. As such, financial data hold the promise of potentially providing insight into the presence of mistake-based discrimination. Specifically if female-headed firms were systematically under-estimated, this would suggest that female-headed firms would outperform expectations, yielding excess returns. Examining data on S&P 1500 firms over the period 1992-2004 I find no systematic differences in returns to holding stock in female-headed firms, although this result reflects the weak statistical power of our test, rather than a strong inference that financial markets either do or do not under-estimate female CEOs.

Explaining the Favorite-Longshot Bias: Is it Risk-Love or Misperceptions?

The favorite–long shot bias describes the long-standing empirical regularity that betting odds provide biased estimates of the probability of a horse winning: long shots are overbet whereas favorites are underbet. Neoclassical explanations of this phenomenon focus on rational gamblers who overbet long shots because of risk-love. The competing behavioral explanations emphasize the role of misperceptions of probabilities. We provide novel empirical tests that can discriminate between these competing theories by assessing whether the models that explain gamblers’ choices in one part of their choice set (betting to win) can also rationalize decisions over a wider choice set, including compound bets in the exacta, quinella, or trifecta pools. Using a new, large-scale data set ideally suited to implement these tests, we find evidence in favor of the view that misperceptions of probability drive the favorite–long shot bias, as suggested by prospect theory

Experimental Political Betting Markets and the 2004 Election.

Betting on elections has been of interest to economists and political scientists for some time. We recently persuaded TradeSports to run experimental contingent betting markets, in which one bets on whether President Bush will be re-elected, conditional on other specified events occurring. Early results suggest that market participants strongly believe that Osama bin Laden's capture would have a substantial effect on President Bush's electoral fortunes, and interestingly that the chance of his capture peaks just before the election. More generally, these markets suggest that issues outside the campaign, like the state of the economy, and progress on the war on terror , are the key factors in the forthcoming election.Other Topics

The Role of Shocks and Institutions in the Rise of European Unemployment: The Aggregate Evidence

Two key facts about European unemployment must be explained: the rise in unemployment since the 1960s, and the heterogeneity of individual country experiences. While adverse shocks can potentially explain much of the rise in unemployment, there is insufficient heterogeneity in these shocks to explain cross-country differences. Alternatively, while explanations focusing on labor market institutions explain cross-country differences explain current heterogeneity well, many of these institutions pre-date the rise in unemployment. Based on a panel of institutions and shocks for 20 OECD nations since 1960, we find that the interaction between shocks and institutions is crucial to explaining both stylized facts. We test two specifications, and each offers significant support for our interactions hypothesis. The first speculation assumes that there are common but unobservable shocks across countries, and that these shocks have a larger and more persistent effect in countries with poor labor market institutions. The second constructs series for the macro shocks, and again finds evidence that the same size shock has differential effects on unemployment when labor market institutions differ. We interpret this as suggesting that institutions determine the relevance of the unemployed to wage-setting, thereby determining the evolution of equilibrium unemployment rates following a shock.

Aggregate Shocks or Aggregate Information? Costly Information and Business Cycle Comovement

Synchronized expansions and contractions across sectors define business cycles. Yet synchronization is puzzling because productivity across sectors exhibits weak correlation. While previous work examined production complementarity, our analysis explores complementarity in information acquisition. Because information about future productivity has a high fixed cost of production and a low marginal cost of replication, sectors can share the cost to forecast their sector-specific productivity. Sectors with common, aggregate information make highly correlated productions choices. By filtering out sector-specific shocks and transmitting aggregate ones, information markets amplify business-cycle comovement.

Economic Growth and Subjective Well-Being: Reassessing the Easterlin Paradox

The “Easterlin paradox” suggests that there is no link between a society’s economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive link between average levels of subjective well-being and GDP per capita across countries, and find no evidence of a satiation point beyond which wealthier countries have no further increases in subjective well-being. We show that the estimated relationship is consistent across many datasets and is similar to the relationship between subject well-being and income observed within countries. Finally, examining the relationship between changes in subjective well-being and income over time within countries we find economic growth associated with rising happiness. Together these findings indicate a clear role for absolute income and a more limited role for relative income comparisons in determining happiness.happiness, subjective well-being, Easterlin Paradox, life satisfaction, economic growth, well-being-income gradient, hedonic treadmill
