Shirking and employment protection legislation: Evidence from a natural experiment

The Italian employment protection legislation was modified in 1990 making more costly for small firms to dismiss employees. Using a difference-in-differences estimator to compare absenteeism rates in small and large firms we find a strong increase of shirking in small firms.     

Lab and framed lab versus natural experiments: Evidence from a risky choice experiment

Some recent papers have studied data from TV game shows to examine the behaviour of individuals towards risk. It is generally agreed that data from these shows are useful in detecting individual risk aversion in the field, with both “real life” subjects and incentives. Field experiments also include some interesting reality features that could affect individuals’ behaviour and possibly lead to different findings. This paper aims at investigating lab versus field evidence in risk taking attitudes, especially controlling for framing effects. To assess whether the behaviour of subjects in the field is consistent with that of experimental subjects, we designed an experiment to mimic (with experimental rewards and subjects) the rules of a well-known Italian TV game show, Affari Tuoi, in two different settings: a traditional lab setting, where the game was played individually (109 subjects) (Treatment 1); and a framed lab, in which the experiment was replicated in the Italian public television (RAI) studio where the show was actually recorded, with a smaller sample of undergraduate students (33) and in the presence of an audience (Treatment 2). Our comparison between the two different settings aims at establishing whether the presence of an audience, or of a situation that reproduces the stress that contestants must experience in the TV studio, can affect experimental subjects’ choices. We did not find any significant evidence of framing effects: students behave in a similar way in the two lab settings, responding essentially to incentives. Comparing the risk attitudes shown by experimental subjects in the two lab treatments with those exhibited by the contestants in the field, we found that contestants in the TV show are generally more risk averse than students in the lab.     

Income comparisons and attitudes towards foreigners - Evidence from a natural experiment

We exploit a natural experiment related to the German re-unification to address whether disutility from income comparisons affects attitudes towards foreigners. Our empirical approach rests upon East German individuals with West German relatives and friends. We use the exogenous variation of wealth of West Germans shortly after the fall of the Berlin Wall as an instrument to identify the effect of disutility from income comparisons on East Germans’ attitudes. We find robust evidence that East Germans express more negative attitudes towards foreigners, particularly from low-wage countries, if they worry about their economic status compared to better-off West Germans.     

The response to incentives and contractual efficiency: Evidence from a field experiment

We use data from a field experiment to estimate worker reaction to incentives and the optimality of piece-rate contracts. Our estimate of the elasticity of output with respect to piece rates is 0.39. Regression methods cannot predict performance under hypothetical contracts. Therefore, we apply structural econometric methods (without imposing profit maximization) to evaluate observed-contract optimality. Using profit as a metric, we estimate the distance between observed and profit-maximizing contracts to be negligible. This suggests that observed contracts closely approximate optimal contracts under asymmetric information about worker ability. Under complete information, the firm could increase expected profits by 14 percent keeping workers indifferent to the observed piece-rate contract. Profits could increase between 44 and 49 percent if the firm exploited information about ability to reduce worker utility to the outside alternative.     

The relative importance of capital inflows: some evidence from emerging market economies

This article examines the relative importance of the main components of capital inflows for a sample of emerging market economies. Does composition matter? Is there a nexus between capital inflow components? We assess, firstly, how each capital inflow component reacts to important macro and policy variables, and secondly, how the components themselves interact. We find that bank inflows appear the most sensitive to macro factors, institutions matter more for Latin America and external financial factors matter more for Asia. Further, for Latin America, capital inflows interact largely as complements, while for Asia, any expansion of bank inflows might crowd out FDI and portfolio flows.     

Workers' compensation and injury duration: evidence from a natural experiment

This paper examines the effect of workers' compensation on time out of work. It introduces a "natural experiment8 approach of comparing individuals injured before and after increases in the maximum weekly benefit amount. The increases examined in Kentucky and Michigan raised the benefit amount for high-earnings individuals by approximately 50 percent, while low-earnings individuals, who were unaffected by the benefit maximum, did not experience a change in their incentives. Time out of work increased for those eligible for the higher benefits and remained unchanged for those whose benefits were constant. The estimated duration elasticities are clustered around 0.3-0.4.     

Gift giving and worker productivity: Evidence from a firm-level experiment

We present results from a field experiment, designed to measure worker response to a monetary gift from their employer. The experiment took place inside a tree-planting firm paying its workforce incentive contracts. Firm managers told a crew of tree planters they would receive a pay raise for one day as a result of a surplus not attributable to past planting productivity. We compare planter productivity—the number of trees planted per day—on the day the gift was handed out with productivity on previous and subsequent days of planting on the same block, and thus under similar planting conditions. We find direct evidence that the gift had a significant and positive effect on daily planter productivity, controlling for planter-fixed effects, weather conditions and other random daily shocks.     

Degree performance of Economics students in UK universities: absolute and relative performance in prior qualifications

We exploit individual‐level data on full cohorts of UK university leavers who were enrolled for an Economics degree during the period 1984–85 to 1992–93 or the academic year 1997–98. We analyse the determinants of degree performance and find that performance depends not only on prior qualifications as measured by A‐level scores, for example, but also on the individual student's ranking (based on their A‐level scores) within their cohort at their university. The students' performance is also enhanced by having previously studied mathematics, although there is no benefit from the prior study of Economics. We find that attendance at an Independent school has a negative effect on degree performance, and that there are comparatively few social class background effects. Females are more likely than males to obtain a good degree.     

The effects of a financial literacy intervention on the financial and economic knowledge of high school students

The authors taught financial concepts to students in 12th-grade economics classes, where one treatment was intensive in money management (MM) topics and the other was intensive in financial investment (FI) topics. Two control groups, consisting of 11th-grade students with no exposure to economics and 12th-grade economics students, received no treatment. Both treatment groups showed a 13 percentage point increase in test scores from pretest to posttest, while neither control group showed gains. Neither treatment group outperformed the other in the financial literacy test.     

The optimal initial allocation of pollution permits: a relative performance approach

The initial allocation of pollution permits is an important aspect of emissions trading schemes. We generalize the analysis of Böhringer and Lange (2005, Eur Econ Rev 49(8): 2041–2055) to initial allocation mechanisms that are based on inter-firm relative performance comparisons (including grandfathering and auctions, as well as novel mechanisms). We show that using firms’ historical output for allocating permits is never optimal in a dynamic permit market setting, while using firms’ historical emissions is optimal only in closed trading systems and only for a narrow class of allocation mechanisms. Instead, it is possible to achieve social optimality by allocating permits based only on an external factor, which is independent of output and emissions. We then outline sufficient conditions for a socially optimal relative performance mechanism.     

Effects of supervision on tax compliance: Evidence from a field experiment in Austria

We conduct a field experiment on tax compliance, focusing on newly founded firms. As a novelty the effect of tax authorities’ supervision on timely tax payments is examined. Interestingly, results show no positive overall effect of close supervision on tax compliance.     

Merger and acquisition FDI,relative wealth and relative access to bank credit: Evidence from a bivariate zero-inflated count model

We use a bivariate zero-inflated negative binomial model to examine Japanese merger and acquisition (M&A) FDI jointly with other types of Japanese FDI (or non-M&A FDI) into the United States. We find that for firms likely to engage in FDI, their rates of FDI are affected by the financial health of their main banks. However, only the rate of M&A FDI is affected by relative wealth. The rate of non-M&A FDI is affected by profitability and firm size. Our findings show the importance of distinguishing M&A FDI from non-M&A FDI and of considering the two types of FDI jointly.     

Improving consumption measurement and other survey data through CAPI: Evidence from a randomized experiment

This paper reports on a randomized survey experiment among 1840 households, designed to compare pen-and-paper interviewing (PAPI) to computer-assisted personal interviewing (CAPI). We find that PAPI data contain a large number of errors, which can be avoided in CAPI. Error counts are not randomly distributed across the sample, but are correlated with household characteristics, potentially introducing sample bias if dubious observations need to be dropped. We demonstrate a tendency for the spread of total measured consumption to be higher on paper compared to CAPI, translating into significantly higher measured inequality. Investigating further the nature of PAPI's measurement error for consumption, we fail to reject the hypothesis that it is classical: it attenuates the coefficient on consumption when used as explanatory variable and we find no evidence of bias when consumption is used as dependent variable. Finally, CAPI and PAPI are compared in terms of interview length, costs and respondents' perceptions.     

The price elasticity of demand for pharmaceuticals amongst high-income older Australians: a natural experiment

Most high-income older Australians became eligible for a pharmaceutical concession through a 1999 policy change. I exploit this natural experiment to estimate their price elasticity of demand for pharmaceuticals. The preferred model is a nonlinear Instrumental Variable (IV) regression, estimated on nationally representative repeated cross-sectional survey data using the Generalized Method of Moments (GMM). No significant evidence is found for endogenous take-up, and so cross-sectional estimates are also considered. Taking all of the results into account, the ‘headline’ estimate is ?0.1, implying that quantity demanded is not highly responsive to price.     

The market process of capitalization: a laboratory experiment on the effectiveness of private information

The notion of present value is an integral part of economics. So far, however, its rationale rests upon the well-known neoclassical assumptions of complete information and perfect rationality. The present value derives as the result of a calculation that requires the knowledge of the discount rate and the future returns of the evaluated assets. This paper presents a laboratory experiment that demonstrates that the present value of assets can also be discovered by participants of a production process endowed with incomplete information. The knowledge concerning future returns is not given to any one, but dispersed among the participants who, in addition, have no idea of their position in the production chain. In accordance with Hayek’s theory of the market process as a discovery procedure, the present value is found without any one subject being able to determine it individually.     

Transmission of information within transnational social networks: a field experiment

Several studies have shown a relationship between the stocks of migrants and country-level investment in the home country; however the mechanism through which this relationship operates is still unexplored. We use a field experiment in which participants who are recent immigrants send information about risky decisions to others in their social network in their home country. The results demonstrate how this information influences decisions in the home country. We find that the advice given by family members and decisions made by friends significantly affects an individual’s risky decision-making.     

Child welfare programs and child nutrition: Evidence from a mandated school meal program in India

Utilizing the data I collected on a nationally mandated school meal program in India, I examine the extent to which children benefit from the targeted public transfer. Relying upon built-in randomness in whether a child's 24-hour food consumption recall was for a school or non-school day, I find that the daily nutrient intake of program participants increased substantially by 49% to 100% of the transfers. The results are robust to the potential endogeneity of program placement and individual participation. The findings suggest that for as low a cost as 3 cents per child per school day the scheme reduced the daily protein deficiency of a primary school student by 100%, the calorie deficiency by almost 30% and the daily iron deficiency by nearly 10%. At least in the short-run, therefore, the program had a substantial effect on reducing hunger at school and protein-energy malnutrition.     

Poverty projection using a small area estimation method: Evidence from Vietnam

For poverty monitoring and evaluation, one needs poverty estimates at the different disaggregation levels. The prediction of poverty trend is also of interest for policy makers as well as researchers. This paper presents a method – that is based on a small area estimation method of Elbers et al. (2003) – to project a map of disaggregated poverty measures in the future. This method is applied to project a poverty map in rural Vietnam for the year 2008 using the 2006 Rural, Agricultural and Fishery Census and the 2004 and 2006 Vietnam Household Living Standard Surveys.     

The momentum effect on Chinese real estate stocks: Evidence from firm performance levels

This paper investigates the momentum effects under different firm performance levels for Chinese real estate stocks using quantile regression with a dummy variable estimator. This paper finds that regardless of the momentum horizon, the momentum effects are positive under high-performing individual stocks, but they are negative under low-performing individual stocks. While prior literature only finds that this asymmetric phenomenon appears under different market states, and the findings on different horizons are inconsistent. Furthermore, this paper finds that the positive (negative) momentum effect under high (low) firm performance levels is stronger than that under bullish (bearish) markets. This implies that superior (inferior) fundamental business performance and bullish (bearish) markets can cause the stock prices to go up (down); however, the effect of the former is stronger than that of the latter. Moreover, this paper finds that the relation between future returns and past turnover ratios is positively correlated under high-performing stocks, but negatively correlated under low-performing stocks. Based on the above findings, this paper regards past turnover ratios as a leading indicator of stock returns and suggests two profitable investment portfolios which are superior to the average returns of real estate stocks.
