Despite its growth in other areas of economics,time series econometric methods have not been widespread in the area of environmental and resource economics. We illustrate one use of time series methods by examining the time path of US nitrogen oxide (NOx) emission data over the period 1900-1994. The analysis highlights that proper time series methods can aid in optimal regulatory policy as well as developing empirical verification of theories put forth to explain economic phenomena. In addition, several interesting results emerge. First, we find that the emissions series contains both a permanent and random component. Second, if one attributed all of the emissions reductions to regulatory policy, intervention analysis suggests that the 1970 Clean Air Act(CAA) did not merely have transitory effects,but permanently influenced the NOx emission path. In terms of total regulatory impact, an upper bound on the emissions saved due to the 1970 CAA is in the range of 27%-48%.

Previous studies of income distribution have found evidence indicating that incomes across U.S. regions have converged, supporting the prediction of the neoclassical growth model. A potential shortcoming in these studies is that only one measure of well-being is considered a measure of wealth linked to incomes or production. This paper examines whether income convergence was accompanied by air pollutant emission convergence. Results from unit root tests provide some evidence that indicators of environmental quality have converged across U.S. regions during the 1929-1994 period.

Using a field experiment, we investigate whether, and if so, how spam is targeted. By comparing the spam rates among a set of synthetic email accounts, we find that spam is targeted to clients of particular email providers, users who declared interest in particular products or services, and consumer segments that are relatively more likely to make online purchases.

Recent research has posited that, in advanced economies, there is a positive correlation between income inequality and development. Using a new unbalanced panel dataset for 71 countries from 1961 to 1992, we present evidence that supports this conjecture. Although many factors may be contributing to this renewed positive relationship between growth and inequality, one plausible explanation rests on the shift away from a manufacturing base towards a service base in most advanced economies.

The Clean Air Act and its subsequent amendments have been lauded as the primary stimulant to the impressive improvement in local air quality in the US since 1970. A key component of these regulations is the New Source Review (NSR) requirement, which includes the contentious stipulation that when an existing plant seeks to modify its operations, the entire plant must comply with current standards for new sources. This requirement was included to improve air quality in dirty areas, and prevent a deterioration of air quality in clean areas. Yet, whether NSR provides the proper plant-level incentives is unclear: there are strong disincentives to undertake major plant modifications to avoid NSR. In our examination of more than 2500 and 2200 plant-level modification decisions and closures, respectively, we find empirical evidence suggesting that NSR retards modification rates, while doing little to hasten the closure of existing dirty plants.

One particularly vexing puzzle for economists and policymakers over the past several decades concerns the empirical significance of the theoretically predicted pollution haven hypothesis. While neoclassical theory and conventional wisdom both surmise that local economies will suffer deleterious effects from stricter environmental regulations, empirical studies have largely failed to validate such claims. This study utilizes the method of matching to show that the impact of stricter regulation is heterogeneous spatially, varying systematically based on location-specific attributes. Previous studies that assume a homogenous response may therefore inadvertently mask the overall impact of more stringent regulations by pooling unaffected and affected regions.

Recent auction theory and experimental results document strategic demand reduction by bidders in uniform-price auctions. The present article extends this area of research to consider the effects of varying the number of bidders. Our theoretical model predicts that demand reduction should decrease with an increase in the number of bidders. Considerable demand reduction remains even in the asymptotic limit, although truthful bidding yields profits very close to those of equilibrium play. We experimentally confirm several of our predictions by examining bidding behavior of subjects in an actual marketplace, auctioning dozens of sportscards using both uniform-price and Vickrey auction formats.

In the spirit of the International Labour Organisation Code (2001) of decent work and respect for the human rights and dignity of persons infected or affected by HIV/AIDS, there should be no discrimination against applicants for work on the basis of real or perceived HIV status. Whilst, the successful implementation of an HIV/AIDS policy requires cooperation and trust between firms and employees, with the active involvement of workers infected and affected by HIV/AIDS (ILO [2007]). In the current study having considered the fundamental points the first ever correspondence testing was conducted in order to test whether job applicants living with HIV (still) face prejudices in the crucial stage of the selection process in Greece. Resumes differed only in applicants' health status were faxed to advertised job openings. We suggest that a HIV-positive applicant may want to identify whether firms are prone to provide any reasonable adjustments for the recruitment and interview process. Definitely, the outcomes must imply that employers use health condition as a factor when reviewing resumes, which matches the legal definition of discrimination. The rate of net discrimination against male (female) HIV positives is found to be between 82.6% and 97.8% (81.6%-98.8%) among sectors. Whilst, the degree of discrimination is randomly assigned across occupations disrelated to education level and job status. The current study initiates a key methodology which can drive world-wide researchers to conduct relevant surveys. As efforts grow up to address HIV discrimination, so does the need for a set of standard tested and validated discrimination indicators. Measurements and discrimination trends are a key tool for identifying effective anti-stigma programming.

In his comment, Mitesh Kataria (2014) makes three main points about a specific part of our paper (Maniadis, Tufano, and List 2014), namely about Tables 2 and 3. In our paper, we employ these tables in order to illustrate the idea that very inconclusive post-study probabilities that a tested phenomenon is true may result from novel, surprising findings. The main arguments in Kataria (2014) are the following: First, if P(H0) is unknown, as is often the case with economic applications, the post-study probability can lead to even worse inference than the Classical significance test, depending on the quality of the prior. Second, the simulation in Maniadis et al. (2014) ignores previous assessments of P(H0) and instead utilizes a selective empirical setup that favors the use of post-study probabilities. [Third,] contrary to what Maniadis et al. (2014) argue, their results do not allow for drawing general recommendations about which approach is the most appropriate. (Kataria 2014, abs.) We believe that our work might have been misunderstood by Kataria. Moreover, it seems that some of his claims are not supported by relevant empirical evidence.

This paper uses county-level panel data to test the appropriateness of the 'one size fits all' reduced-form regression approach commonly used when estimating the economic model of crime. Empirical results provide initial evidence that previous studies, which restrict deterrent effects to have identical impacts across crime types, may be presenting statistically biased results.

We employ a two-step modified count data model to determine the county-level attributes that are conducive to attracting new foreign plants. Our estimation results indicate that previous counts of foreign direct investment, market size and accessibility, and land area are positively related to Foreign Direct Investment (FDI) occurrences; while higher input costs deter new foreign firm entry. Contrary to anecdotal evidence, our results suggest that stringent environmental regulations do not have a negative impact on FDI inflows. These findings have significant implications for policymakers, as flows of FDI are expected to increase dramatically given the economic integration of our global economy.

Recently an important line of research using laboratory experiments has provided a new potential reason for why we observe gender imbalances in labor markets: men are more competitively inclined than women. Whether, and to what extent, such preferences yield differences in naturally-occurring labor market outcomes remains an open issue. We address this question by exploring job-entry decisions in a natural field experiment where we randomized nearly 7,000 interested job-seekers into different compensation regimes. By varying the role that individual competition plays in setting the wage, we are able to explore whether competition, by itself, can cause differential job entry. The data highlight the power of the compensation regime in that women disproportionately shy away from competitive work settings. Yet, there are important factors that attenuate the gender differences, including whether the job is performed in teams, whether the job task is female-oriented, and the local labor market.

This study examines data drawn from the game show Friend or Foe?, which is similar to the classic prisoner's dilemma tale: partnerships are endogenously determined, players work together to earn money, after which, they play a one-shot prisoner's dilemma game over large stakes: varying from $200 to (potentially) more than $22,000. If one were to conduct such an experiment in the laboratory, the cost to gather the data would be well over $350,000. The data reveal several interesting insights; perhaps most provocatively, they suggest that even though the game is played in front of an audience of millions of viewers, there is some evidence consistent with a model of discrimination. The observed patterns of social discrimination are unanticipated, however. For example, there is evidence consistent with the notion that certain populations have a general "distaste" for older participants.

Given the importance of job placement for Ph.D.s, it is surprising that economists have not closely examined the factors that affect procuring job interviews for new Ph.D. economists.' In this study, I investigated those factors using a data set gathered at the 1997 American Economic Association (AEA) meetings in New Orleans. My purpose was to increase the information available to Ph.D. candidates who wish to maximize their postgraduation job prospects. In addition, this study may guide undergraduates and master's candidates who seek to pursue a Ph.D. in economics. The results of the findings, however, could benefit more than job seekers-they may provide academic departments and private industry with a comparative baseline for making decisions to interview job candidates. The job market for new Ph.D.s consists of two submarkets-academic and businesshndustry. The following are questions regarding job seekers in both submarkets. (1) Do employers in academia seek the same attributes as businesshndustry? (2) Is there discrimination in the interview decision? (3) Is an MBA important in the Ph.D. market? (4) How many more interviews are secured by candidates with a finished dissertation? (5) How important are teaching and research credentials? (6) Are graduates from top-ranked programs given special consideration in the job market? (7) Do personal letters of recommendation or calls from professors make a difference in the interview decision? (8) How influential are recommendation letters from prestigious economists? (9) What is the marginal effect of submitting another application? A simple theoretic construct provides a basis for understanding the two-step job-search process carried out by new Ph.D. economists.* In the first step, the job seeker decides whether to enter one or both submarkets and determines the optimal number of applications to submit. The second step reflects the actual decision process regarding acceptance or rejection of a job offer. Because a natural prerequisite to securing a job is an initial interview, my main focus in this study was to discover the optimal job search strategies for new Ph.D. economists by determining applicant characteristics that are conducive to obtaining interviews.

Political campaigns currently make extensive use of direct mail, particularly in state and local races, yet its effects on voter behavior are not well understood. This essay presents the results of large-scale randomized field experiments conducted in Connecticut and New Jersey during state and municipal elections of 1999. Tens of thousands of registered voters were sent from zero to nine pieces of direct mail. The target populations included party registrants with a strong history of voter participation, independents, and a random subset of registered voters. Our results indicate partisan campaign mail does little to stimulate voter turnout and may even dampen it when the mail is negative in tone.

We use a field experiment to study how workers value alternative work arrangements. During the application process to staff a national call center we randomly offered applicants choices between traditional M-F 9am - 5pm office positions and alternatives. These alternatives include flexible scheduling, working from home, and positions that give the employer discretion over scheduling. We randomlyvaried the wage difference between the traditional option and the alternative, allowing us to estimate the entire distribution of willingness to pay (WTP) for these alternatives. We validate our results using a nationally-representative survey. The great majority of workers are not willing to pay for flexible scheduling relative to a traditional schedule: either the ability to choose the days and times of work or the number of hours they work. However, the average worker is willing to give up 20% of wages to avoid a schedule set by an employer on a week's notice. This largely represents workers' aversion to evening and weekend work, not scheduling unpredictability. Traditional M-F 9am - 5pm schedules are preferred by most jobseekers. Despite the fact that the average worker isn't willing to pay for scheduling flexibility, a tail of workers with high WTP allows for sizable compensating differentials. Of the workerfriendly options we test, workers are willing to pay the most (8% of wages) for the option of working from home. Women, particularly those with young children, have higher WTP for work from home and to avoid employer scheduling discretion. They are slightly more likely to be in jobs with these amenities, but the differences are not large enough to explain any wage gaps.

In this paper we examine temporal properties of eleven natural resource real price series from 1870-1990 by employing a Lagrangian Multiplier unit root test that allows for two endogenously determined structural breaks with and without a quadratic trend. Contrary to previous research, we find evidence against the unit root hypothesis for all price series. Our findings support characterizing natural resource prices as stationary around deterministic trends with structural breaks. This result is important in both a positive and normative sense. For example, without an appropriate understanding of the dynamics of a time series, empirical verification of theories, forecasting, and proper inference are potentially fruitless. More generally, we show that both pre-testing for unit roots with breaks and allowing for breaks in the forecast model can improve forecast accuracy.

This paper uses state-level pollution data from 1986-1997 to construct two indices that rank U.S. states according to environmental outputs. A major finding is that marginal performers in other indices, such as Wyoming, garner top spots in these ranking systems. The paper also presents findings from fixed and random effects models of panel data that imply state income levels are positively associated with environmental outputs after a threshold level of income is obtained.

An important public policy question that remains unresolved is whether devolution will enhance sensible policy making by exploiting informational asymmetries or, instead, trigger a "beggar thy neighbor" response and stimulate free riding amongst localities. We analyze this question within the framework of U.S. environmental policy making by scrutinizing a unique panel data set on state-level endangered species expenditure patterns. Our empirical estimates are consistent with the notion that states free ride, which may lead to an expenditure equilibrium that is not Pareto efficient.
