Charter Schools’ Effectiveness, Mechanisms, and Competitive Influence

Across the United States, charter schools—publicly funded and regulated, but privately run schools—appear to perform, on average, at about the same level as their district counterparts. The broadest studies of charter school effectiveness use observational methods, which may not fully account for selection of students into charter schools. However, this finding is confirmed by lottery-based evidence from a few broad samples that again presents a varied picture of charter impact and little average difference across sectors. Underlying the similarity in performance across sectors is one of the most consistent findings from both observational and lottery-based evidence of charter schools’ impact on student achievement: Charters located in urban areas boost student test scores, particularly for Black, Latinx, and students from lower-income households. The test score gains appear to be largest in urban charters that employ “No Excuses” practices. Attending some urban charter schools also increases college enrollment and voting and reduces risky behavior. However, evidence on such long-term outcomes is limited to a few samples, and evidence on college graduation and adult earnings is even rarer, making it difficult to draw conclusions beyond test scores about the overall effectiveness of the charter sector. Research on the mechanisms underlying charter successes, when they occur, is growing. No Excuses charter schools—which employ high expectations, strict disciplinary codes, and intense academic focus—generate consistent test score gains, but their controversial disciplinary practices are not necessarily a condition for academic success. Charter school teachers tend to be less qualified and more likely to leave the profession than traditional public school teachers, though the impact of these challenges for the labor market is understudied. Similarly, the influence of charter authorizers and related accountability structures is limited and would benefit from examination using more rigorous methodologies. The competitive impact of charter schools on traditional public schools typically suggests a small, beneficial influence on neighboring schools’ student achievement, though there is variation across contexts. Additionally, while some local analyses suggest charters reduce funding in nearby districts, at least in the short term, a larger scale study finds charter entry generates more revenue per pupil for district schools. There is competing evidence on charters’ contribution to school racial segregation, and little evidence on the impact of newer, intentionally diverse school models. In all, more research, in more contexts, is needed to further understand where, for whom, and why charters are most effective.

The Economic Effect of Vocational Education on Student Outcomes

As long as formal education has existed, there has been a clear connection between education and preparation for employment. In much of the world, formal educational systems have come to include vocational education and training (VET) as part of secondary education. In these spaces, individuals can receive continued training in general skills related to reading, writing, and mathematics while also pursuing specific skills in prescribed vocational or technical programs (e.g., skilled trades, culinary arts, information technology, health services). Across all countries and associated educational systems, a tension exists between whether to invest educational dollars in general versus specific skill development. On the one hand, general skills allow for transferability and likely support adaptability across workplace settings and in response to changes in employment conditions. On the other hand, secondary school completion is not universal, even in rich countries, and there are often large penalties or social costs to not completing secondary education. Furthermore, across countries of varying GDP levels, the question about how to best prepare individuals for entry into and success in the workforce is a persistent one. Evidence suggests that the payoff to investments in VET vary considerably, and that context and the characteristics of participants likely inform the expected returns to such investments. For instance, there is strong evidence across contexts that male participants in VET are likely to benefit in the short- to medium-term with respect to employment and earnings, and possibly also engage in less crime. Unresolved, however, is whether these payoffs persist in the longer term. In contrast, for women the estimated returns appear to be more context dependent. Some research shows reduced fertility and greater financial independence of women participating in VET programs in less-developed countries, but evidence is mixed in other settings. All evidence underscores that the payoff to VET is likely tied to the extent to which it adapts to contemporary economic needs, including extending the amount of total formal education that participants might otherwise receive.

Religiosity and Development

Economics of religion is the application of economic methods to the study of causes and consequences of religion. Ever since Max Weber set forth his theory of the Protestant ethic, social scientists have compared socioeconomic differences across Protestants and Catholics, Muslims, and Christians, and more recently across different intensities of religiosity. Religiosity refers to an individual’s degree of religious attendance and strength of beliefs. Religiosity rises with a growing demand for religion resulting from adversity and insecurity or a surging supply of religion stemming from increasing numbers of religious organizations, for instance. Religiosity has fallen in some Western countries since the mid-20th century, but has strengthened in several other societies around the world. Religion is a multidimensional concept, and religiosity has multiple impacts on socioeconomic outcomes, depending on the dimension observed. Religion covers public religious activities such as church attendance, which involves exposure to religious doctrines and to fellow believers, potentially strengthening social capital and trust among believers. Religious doctrines teach belief in supernatural beings, but also social views on hard work, refraining from deviant activities, and adherence to traditional norms. These norms and social views are sometimes orthogonal to the general tendency of modernization, and religion may contribute to the rising polarization on social issues regarding abortion, LGBT rights, women, and immigration. These norms and social views are again potentially in conflict with science and innovation, incentivizing some religious authorities to curb scientific progress. Further, religion encompasses private religious activities such as prayer and the particular religious beliefs, which may provide comfort and buffering against stressful events. At the same time, rulers may exploit the existence of belief in higher powers for political purposes. Empirical research supports these predictions. Consequences of higher religiosity include more emphasis on traditional values such as traditional gender norms and attitudes against homosexuality, lower rates of technical education, restrictions on science and democracy, rising polarization and conflict, and lower average incomes. Positive consequences of religiosity include improved health and depression rates, crime reduction, increased happiness, higher prosociality among believers, and consumption and well-being levels that are less sensitive to shocks.

Economic Studies on the Opioid Crisis: Costs, Causes, and Policy Responses

The United States has experienced an unprecedented crisis related to the misuse of and addiction to opioids. As of 2018, 128 Americans die each day of an opioid overdose, and total economic costs associated with opioid misuse are estimated to be more than $500 billion annually. The crisis evolved in three phases, starting in the 1990s and continuing through 2010 with a massive increase in use of prescribed opioids associated with lax prescribing regulations and aggressive marketing efforts by the pharmaceutical industry. A second phase included tightening restrictions on prescribed opioids, reformulation of some commonly misused prescription medications, and a shift to heroin consumption over the period 2010 to 2013. Since 2013, the third phase of the crisis has included a movement toward synthetic opioids, especially fentanyl, and a continued tightening of opioid prescribing regulations, along with the growth of both harm reduction and addiction treatment access policies, including a possible 2021 relaxation of buprenorphine prescribing regulations. Economic research, using innovative frameworks, causal methods, and rich data, has added to our understanding of the causes and consequences of the crisis. This body of research identifies intended and unintended impacts of policies designed to address the crisis. Although there is general agreement that the causes of the crisis include a combination of supply- and demand-side factors, and interactions between them, there is less consensus regarding the relative importance of each. Studies show that regulations can reduce opioid prescribing but may have less impact on root causes of the crisis and, in some cases, have spillover effects resulting in greater use of more harmful substances obtained in illicit markets, where regulation is less possible. There are effective opioid use disorder treatments available, but access, stigma, and cost hurdles have stifled utilization, resulting in a large degree of under-treatment in the United States. How challenges brought about by the COVID-19 pandemic may intersect with the opioid crisis is unclear. Emerging areas for future research include understanding how societal and health care systems disruptions affect opioid use, as well as which regulations and policies most effectively reduce potentially inappropriate prescription opioid use and illicit opioid sources without unintended negative consequences.

Modern Norwegian Economic History

Since Norway’s formation as an independent sovereign state in 1814, its small open economy has, like its neighboring countries, experienced significant economic growth. During the last several decades petroleum has made the country one of the wealthiest in the world. The main reason for the long-term growth seems to have been the ability to meet international demand by utilizing rich natural resources, adopting efficient technology, and drawing on the labor force in order to gain high productivity. Historical national accounts reveal that Norway’s wealth was close to the Western European average during the early 19th century. From the 1840s to the mid-1870s, Norwegian growth rates were clearly better than average. This period was followed by relative stagnation until the 1890s, when the country saw rapid industrialization based on hydroelectricity. After the two World Wars Norway adopted a social democratic rule, with a high degree of economic planning, called the Nordic model. This has contributed to a large public sector and evenly distributed wealth and resources. The discovery of oil and gas on the Norwegian continental shelf marked a new era, when Norway experienced higher growth rates than most Western economies. This has made it the country with the highest score in the United Nations Human Development Index (HDI) during the two first decades of the 21st century, despite a slowdown in growth after the financial crisis in 2008.

The Contribution of Vocational Education and Training to Innovation and Growth

Despite the common view that innovation requires academically educated workers, some countries that strongly emphasize vocational education and training (VET) in their education systems—such as Switzerland and Germany—are highly competitive internationally in terms of innovation. These countries have dual VET programs, that is, upper-secondary-level apprenticeship programs, that combine about three quarters of workplace training with about one quarter of vocational schooling, and design them in such a way that their graduates (i.e., dual apprenticeship-graduates) play crucial roles in innovation processes. Regular updates of VET curricula incorporate the latest technological developments into these curricula, thereby ensuring that dual apprenticeship-graduates possess up-to-date, high-level skills in their chosen occupation. This process allows these graduates to contribute to innovation in firms. Moreover, these graduates acquire broad sets of technical and soft skills that enhance their job mobility and flexibility. Therefore, conventional wisdom notwithstanding, dual apprenticeship-graduates in such countries not only have broad skill sets that accelerate innovation in firms, but also willingly participate in innovation because of their high flexibility and employability. Moreover, Switzerland and Germany have tertiary-level VET institutions that foster innovation. These are universities of applied sciences (UASs), which teach and conduct applied research, thereby helping build a bridge between different types of knowledge (vocational and academic). UAS students have prior vocational knowledge through their dual apprenticeship and acquire applied research skills from UAS professors who usually have both work experience and a doctoral degree from an academic university. Thus UAS graduates combine sound occupational knowledge with applied research knowledge inspired by input from the academic research frontier and from practical research and development (R & D) in firms. Firms employ UAS graduates with their knowledge combination as an important input for R & D. Consequently, regions with a UAS have higher levels of innovation than regions without one. This effect is particularly strong for regions outside major innovation centers and for regions with larger percentages of smaller firms.

The Economics of Identity and Conflict

Conflicts are a ubiquitous part of our life. One of the main reasons behind the initiation and escalation of conflict is the identity, or the sense of self, of the engaged parties. It is hence not surprising that there is a consistent area of academic literature that focuses on identity, conflict, and their interaction. This area models conflicts as contests and focuses on the theoretical, experimental, and empirical literature from economics, political science, and psychology. The theoretical literature investigates the behavioral aspects—such as preference and beliefs—to explain the reasons for and the effects of identity on human behavior. The theoretical literature also analyzes issues such as identity-dependent externality, endogenous choice of joining a group, and so on. The applied literature consists of laboratory and field experiments as well as empirical studies from the field. The experimental studies find that the salience of an identity can increase conflict in a field setting. Laboratory experiments show that whereas real identity indeed increases conflict, a mere classification does not do so. It is also observed that priming a majority–minority identity affects the conflict behavior of the majority, but not of the minority. Further investigations explain these results in terms of parochial altruism. The empirical literature in this area focuses on the various measures of identity, identity distribution, and other economic variables on conflict behavior. Religious polarization can explain conflict behavior better than linguistic differences. Moreover, polarization is a more significant determinants of conflict when the winners of the conflict enjoy a public good reward; but fractionalization is a better determinant when the winners enjoy a private good reward. As a whole, this area of literature is still emerging, and the theoretical literature can be extended to various avenues such as sabotage, affirmative action, intra-group conflict, and endogenous group formation. For empirical and experimental research, exploring new conflict resolution mechanisms, endogeneity between identity and conflict, and evaluating biological mechanisms for identity-related conflict will be of interest.

Simple and Intuitive Business Practices in Financial Economics

In stark contrast to the sophisticated methods advocated by academics in business schools, actual business practices are typically simple and intuitive (e.g., valuation, debt management, compensation). Methods that have these characteristics are more likely to become widely used business practices for two reasons. First, they are less prone to overfitting to a particular setting and therefore are robust across economic environments and applicable in new settings. Second, they are easy to communicate and are verifiable. Therefore, they can spread easily across organizations and are hard to replace with new and improved methods. This explanation of business practices can help resolve puzzles in corporate finance, such as the variation in debt leverage across industries.

Growth of Global Corporate Debt: Main Facts and Policy Challenges

There has been substantial debate about the expansion of global non-financial corporate debt after the global financial crisis (GFC) of 2008–2009. But the main facts and policy challenges discussed in the literature are yet to be uncovered and summarized. Understanding the trends and issues can help readers gauge how large the growth of this type of financing has been, as well as the risks that more non-financial corporate debt might entail. Non-financial corporate debt steadily increased after the GFC, especially in emerging economies. Between 2008 and 2018, corporate debt rose from 56 to 96% of gross domestic product (GDP) in emerging economies whereas it grew at the same rate as GDP in developed economies. Non-financial corporate debt after the crisis was mainly issued through bond markets, and its growth can be largely attributed to accommodative monetary policies in developed economies. Although the growth in debt financing has some positive aspects for emerging market firms in terms of expanding financing and diversifying financing sources, it also amplified solvency risks and firms’ exposure to changes in market conditions. Slower global economic growth worldwide as a result of the COVID-19 pandemic could impose significant costs to emerging market firms that increased reliance on debt financing. Policy makers in emerging economies face challenges to mitigate overall risks and to contain corporate vulnerability in the non-financial sector. Because capital markets have an important role in the expansion of financial activity and are not as regulated as banks, policy makers have limited tools to alleviate the risks of growing non-financial corporate debt.

Growth Econometrics

Growth econometrics is the application of statistical methods to the study of economic growth and levels of national output or income per head. Researchers often seek to understand why growth rates differ across countries. The field developed rapidly in the 1980s and 1990s, but the early work often proved fragile. Cross-section analyses are limited by the relatively small number of countries in the world and problems of endogeneity, parameter heterogeneity, model uncertainty, and cross-section error dependence. The long-term prospects look better for approaches using panel data. Overall, the quality of the evidence has improved over time, due to better measurement, more data, and new methods. As longer spans of data become available, the methods of growth econometrics will shed light on fundamental questions that are hard to answer any other way.
