Water pricing policies,public decision making and farmers' response: implications for water policy

The problems caused by water scarcity demand important changes in the criteria and objectives of water policies. The agricultural sector in Spain consumes up to 80% of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at the core of the country's national water policy. One alternative would be to resort to water pricing policies with the aim of providing incentives to save water consumption although it would inflict a certain degree of income losses to the farmers and raise the revenue collected by the water authorities. The objective of this research is to analyze the effect caused by the application of different water pricing policies on water demand, farmers' income and the revenue collected by the government agency. To undertake this analysis a dynamic mathematical programming model has been built that simulates farmers' behavior and their response to different water pricing scenarios. Empirical application of the model has been carried out in several irrigation districts in Spain covering varied farm regions and river basins. Results show that the effects of alternative pricing policies for irrigation water are strongly dependent on regional, structural and institutional conditions and that changing policies produce distinct consequences within the same region and water district. Thus, equivalent water charges would create widespread effects on water savings, farm income and collected government revenue across regions and districts.     

Inference for treatment effects of job training on wages: using bounds to compute Fisher’s exact p-value

In the context of a training program’s randomized evaluation, where estimating wage effects is of interest, we propose employing bounds that control for sample selection as a model-based statistic to conduct randomization-based inference à la Fisher. Inference is based on a sharp null hypothesis of no treatment effect for anyone. In contrast to conventional inference, Fisher p-values are nonparametric and do not employ large sample approximations.     

Has financial market integration increased during the nineties?

This paper analyses whether there has been an increase in the degree of financial market integration during the nineties. To do this, we focus on stock markets and compute two alternative measures of market integration based on a refinement of the approach suggested by Chen, Z., Knez, P.J., 1995. [Measurement of market integration and arbitrage, Review of Financial Studies 8(2), 287–325]. The main advantage of this approach is that it relies on the condition of absence of arbitrage opportunities, which is directly related to the idea that more integration means less barriers to trade across markets — and does not depend on any particular asset pricing model. The evidence found suggests that during the nineties there has been an increase of the degree of market integration between stock markets.     

A Note on US Worker Turnover

The length of new employment relationships is of first‐order importance for a number of questions in recent macro‐labour research. We investigate it using data from the Survey of Income and Program Participation for the US from 1996 onwards, and document that above two‐fifths of newly employed workers fall into non‐employment within a year. We also find that the transition rate from employment to non‐employment within the first year varies significantly for different groups of the population, increases with the duration of the previous non‐employment spell, exhibits an acyclical or weakly procyclical pattern and a much higher volatility than the unemployment rate.     

The Role of Foreign Shareholders in Disciplining Financial Reporting

We investigate the role of foreign shareholders in improving the quality of accounting information provided by firms domiciled in countries with low de facto institutional quality. Using a sample of firms from four South European countries (Greece, Italy, Portugal and Spain) for which we observe detailed ownership evolutions over the period 2002–2007, we find that increases in foreign ownership lead to increases in financial reporting quality but only if the foreign shareholders are domiciled in countries with strong investor protection mechanisms. Further, we find that the improvement in financial reporting quality is more pronounced in the case of foreign institutional investors. Finally, our results hold before and after the introduction of the International Financial Reporting Standards (IFRS) in 2005.     

Unobserved Heterogeneity,Exit Rates,and Re‐Employment Wages

Exit rates from unemployment and re‐employment wages decline over a period of unemployment, after controlling for worker observable characteristics. We study the role of unobserved heterogeneity in an economy with asymmetric information and directed search. We show that the unique equilibrium is separating and that skilled workers have more job opportunities and higher wages. The composition of the unemployed varies with the duration of unemployment, so average exit rates and wages fall with time. The separating equilibrium relies on performance‐related pay schemes and the ability of firms to commit to renting an input that is complementary to worker skills.     

The relation between segment disclosure and earnings quality

We investigate the relation between segment disclosure and earnings quality. Using a US sample for the period 2001–2006, we find a positive relation between earnings quality and the quantity of segment disclosures. We use lead-lag tests to examine the flow of causality, and our results show that current segment disclosure is positively related to prior levels of earnings quality, while current earnings quality scores are not related to prior levels of segment disclosure. Thus, the causality flows from earnings quality to segment disclosure. Our results hold for both business and geographic segment disclosure.     

Sources of crime in the state of Veracruz: The role of female labor force participation and wage inequality

Abstract

In recent years, crime has become a serious concern in Mexico as its increase has detrimentally affected government institutions and economic growth. There is considerable speculation among policy analysts about the causes of the increase in crime. Whereas some analysts attribute the increase to a rise in income inequality, others believe internal migration and a loss of morals are the roots of criminal behavior. This research shows that at least for the Mexican state of Veracruz, wage inequality and labor force participation have an important impact on crime. When gender is considered, however, the impact is more complicated than it seems. An increase in women's labor force participation decreases the overall number of alleged violent offenders. However, the number of alleged rapists and grievous bodily harm offenders increases as women's wage distribution improves. The results shed light on the gender dimensions of the economics of crime.     

How do auditors respond to low annual report readability?

We show that increased audit effort is associated with lower annual report readability to compensate for a perceived increase in the risk of financial misstatement for United States (US) firms. In particular, we find that lower annual report readability is associated with longer audit delays and higher audit fees for Form 10-K for US auditors, suggesting that auditors spend more effort auditing clients when annual reports have lower readability. We also find that low readability increases the likelihood of auditors using more explanatory language in unqualified audit reports.
