    Notes: Abstract With existing and proposed air-quality regulations, ecological disasters resulting from air emissions such as those observed at Copperhill, Tennessee, and Sudbury, Ontario, are unlikely. Current air-quality standards, however, may not protect ecosystems from subacute and chronic exposure to air emissions. The encouragement of the use of coal for energy production and the development of the fossil-fuel industries, including oil shales, tar sands, and coal liquification, point to an increase and spread of fossil-fuel emissions and the potential to influence a number of natural ecosystems. This paper reviews the reported responses of ecosystems to air-borne pollutants and discusses the use of animals as indicators of ecosystem responses to these pollutants. Animal species and populations can act as important indicators of biotic and abiotic responses of aquatic and terrestrial ecosystems. These responses can indicate long-term trends in ecosystem health and productivity, chemical cycling, genetics, and regulation. For short-term trends, fish and wildlife also serve as monitors of changes in community structure, signaling food-web contamination, as well as providing a measure of ecosystem vitality. Information is presented to show not only the importance of animals as indicators of ecosystem responses to air-quality degradation, but also their value as air-pollution indices, that is, as air-quality-related values (AQRV), required in current air-pollution regulation.

    Description: This paper examines the role of the sociocultural background of students for choosing STEM fields in university. We combine rich survey data on university graduates in Switzerland with municipality level information from the census as well as nationwide elections and referenda to characterize a students home environment with respect to religious and political attitudes towards gender equality and science-related issues. Our empirical estimates are based on a structural Roy model which accounts for differences in costs (relative distance to the next technical university) and earnings across majors as well as for selection bias. Our findings suggest that male students from conservative municipalities are more likely to study a STEM field, whereas the sociocultural background plays little role for the major choice of females.

    Description: The purpose of this note is to set out the underlying philosophy of the ecosystem services approach as it is applied in UK policy circles. The aim is to clarify some flexible "ground rules" which should guide both the use of this type of decision support tool itself, and the interpretation of its results by the policy community and society at large. The approach taken is built on two key foundation principles: pluralism and pragmatism, which are explained in more detail in this note.

    Description: More than low default rates, lenders are interested in the expected return on their loans. In this paper, we consider a number of other measures of repayment and nonpayment that are likely to be of direct interest to lenders. Using data from the Baccalaureate and Beyond Longitudinal Study, we document repayment and nonpayment outcomes 10 years after grad- uation for American students receiving BA/BS degrees in 1993. We estimate differences in these outcomes across individual/family background characteristics, college major, type of institution, the amount borrowed, and post-graduation income. A key contribution is our analysis of the following outcomes in addition to student loan default rates: the fraction of the original undergraduate loan amount repaid as of 2003, nonpayment rates (including deferment and forbearance as well as default), and the fraction of original undergraduate loan amounts on which borrowers defaulted or are currently not repaying.

    Description: We consider a general framework to study the evolution of wage and earnings residuals that incorporates features highlighted by two influential but distinct literatures in economics: (i) unobserved skills with changing non-linear pricing functions and (ii) idiosyncratic shocks that follow a rich stochastic process. Specifically, we consider residuals for individual i in period t of the form: Wi,t = ut(Øi) + ei,t, where Øi represents an unobserved permanent ability or skill, ut(.) a pricing function for unobserved skills, and ei,t idiosyncratic shocks with both permanent and transitory components. We first provide nonparametric identification conditions for the distribution of unobserved skills, all ut(.) skill pricing functions, and (nearly) all distributions for both permanent and MA(q) transitory shocks. We then discuss identification and estimation using a moment-based approach, restricting ut(.) to be polynomial functions. Using data on log earnings for men ages 30-59 in the PSID, we estimate the evolution of unobserved skill pricing functions and the distributions of unobserved skills, transitory, and permanent shocks from 1970 to 2008. We highlight five main findings: (i) The returns to unobserved skill rose over the 1970s and early 1980s, fell over the late 1980s and early 1990s, and then remained quite stable through the end of our sample period. Since the mid-1990s, we observe some evidence of polarization: the returns to unobserved skill declined at the bottom of the distribution while they remained relatively constant over the top half. (ii) The variance of unobserved skill changed very little across most cohorts in our sample (those born between 1925 and 1955). (iii) The variance of transitory shocks jumped up considerably in the early 1980s but shows little long-run trend otherwise over the more than thirty year period we study. (iv) The variance of permanent shocks declined very slightly over the 1970s, then rose systematically through the end of our sample by 15 to 20 log points. The increase in this variance over the 1980s and 1990s was strongest for workers with low unobserved ability. (v) In most years, the distribution of ut(Ø) is positively skewed, while the distributions of permanent and (especially) transitory shocks are negatively skewed.

    Description: The United States must make a fundamental choice in its economic policy in the next few months, a choice that will shape the US economy for years to come. Pundits and policymakers are divided over how to address what is widely referred to as the "fiscal cliff", a combination of tax increases and spending cuts that will further weaken the domestic economy. Will the United States continue its current, misguided, policy of implementing European-style austerity measures, and the economic contraction that is the inevitable consequence of such policies? Or will it turn aside from the fiscal cliff, using a combination of its sovereign currency system and Keynesian fiscal policy to strengthen aggregate demand? Our analysis presents a model of what we call the "fiscal trap" - a self-imposed spiral of economic contraction resulting from a fundamental misunderstanding of the role and function of fiscal policy in times of economic weakness. Within this framework, we begin our analysis with the disastrous results of austerity policies in the European Union (EU) and the UK. Our account of these policies and their results is meant as a cautionary tale for the United States, not as a model.

    Description: In partnership with the Korea Employment Information Service, Senior Scholar Ajit Zacharias and Research Scholars Thomas Masterson and Kijong Kim investigate the complex issues of gender, changing labor market conditions, and the public provisioning of child care in Korea using the Levy Institute Measure of Time and Income Poverty (LIMTIP), an alternative measure that factors in both time and income deficits in the assessment of poverty. Since the 1997 Asian financial crisis, lifetime employment and single-breadwinner households have given way to increased job insecurity, flexible work arrangements, and rapid growth in dual-earner households in Korea. Add to these factors rising labor force participation by women but little change in the highly unequal division of household production, and many women effectively face a double shift each day: paid employment followed by a second shift of household production. Recognizing the implications of the heavy burden of care work for women's well-being and employment, Korea introduced public child-care provisioning, via a voucher system for low-income families, in 1992 (the program became universal in 2013). This study analyzes the impact of the voucher program on reducing time and income poverty, and reassesses the overall level of poverty in Korea. While it reveals a much higher level of poverty than official estimates indicate - 7.9 percent versus 2.6 percent - due to time deficits, the outsourcing of child-care services reduced the LIMTIP rate from 7.9 percent to 7.5 percent and the number of "hidden poor" individuals from two million to 1.8 million. While these results show that the problem of time poverty in Korea extends beyond child-care needs, the impact of public provisioning through the voucher program clearly has had a positive impact on families with children.

    Description: We cannot adequately assess how much or how little progress we have made in addressing the condition of the most vulnerable in our societies, or provide accurate guidance to policymakers intent on improving each individual's and household's ability to reach a basic standard of living, if we do not have a reliable means of measuring who is being left behind. With the support of the United Nations Development Programme and the International Labour Organization, Senior Scholars Rania Antonopoulos and Ajit Zacharias and Research Scholar Thomas Masterson have constructed an alternative measure of poverty that, when applied to the cases of Argentina, Chile, and Mexico, reveals significant blind spots in the official numbers.

    Description: Conventional wisdom has calcified around the belief that the countries in the eurozone periphery are in trouble primarily because of their governments' allegedly profligate ways. For most of these nations, however, the facts suggest otherwise. Apart from the case of Greece, the outbreak of the eurozone crisis largely preceded dramatic increases in public debt ratios, and as has been emphasized in previous Levy Institute publications, the roots of the crisis lie far more in the flawed design of the European Monetary Union and the imbalances it has generated. But as Research Associate and Policy Fellow C. J. Polychroniou demonstrates in this policy brief, domestic political developments should not be written out of the recent history of the eurozone's stumbles toward crisis and possible dissolution. However, the part in this tale played by southern European political regimes is quite the opposite of that which is commonly claimed or implied in the press. Instead of out-of-control, overly generous progressive agendas, the countries at the core of the crisis in southern Europe - Greece, Spain, and Portugal - have seen their macroeconomic environments shaped by the dominance of regressive political regimes and an embrace of neoliberal policies; an embrace, says Polychroniou, that helped contribute to the unenviable position their economies find themselves in today.
