How Productive Are Economics and Finance PhDs?

This article analyses the research productivity of more than 200 individuals in academe with a PhD in economics and finance from (mostly) Australian universities. We find the number of publications accumulates linearly with experience, while citations increase exponentially, pointing to network effects. Panel regressions indicate: (1) the key role of experience in determining research outcomes; (2) the usual quadratic approach substantially under-estimates the role of diminishing returns to experience; (3) the university where an individual works is mostly unimportant for publications and citations. ‘Prime academic age’, when research has maximum impact, is attained about 11 years after the PhD.     

Reviewers for Volume 41

The authors document the types of undergraduate colleges and universities attended by those who earned a doctorate in economics from an American university from 1966 through 2003. They examine relationships between type of undergraduate institution and attrition and time-to-degree in PhD programs. The total number of new economics PhDs awarded to U.S. citizens has declined precipitously over the past 30 years. Concurrently, the number of new economics doctorates who hold undergraduate degrees from U.S. universities has fallen by half, from a high of about 800 in 1972 to about 400 in 2003. Among those who have earned undergraduate degrees from American institutions, the mix of schools attended by the doctorates has remained relatively stable, with about 55 percent of those who earn a PhD in economics each year holding their bachelor's degree from a university that offers a PhD in economics and a bit more than 10 percent holding a bachelors degree from a selective liberal arts college. Currently, 18 of the 25 American undergraduate institutions that send the largest percentage of their graduating classes on to earn a PhD in economics are liberal arts colleges. Graduates of liberal arts colleges also have shorter time-to-degree and higher verbal Graduate Record Exam (GRE) scores than other economics PhD students.     

Who Cites What?

The present paper analyses citations in the work of a large number of PhD students. We show that the pattern of citations of journal articles, books and other reference material differs substantially across areas within economics. An investigation of reciprocal citations reveals a surprisingly low degree of communication among the Group of Eight universities and a high propensity to cite authors from the same institution, especially supervisors. We also analyse the Australian share of cited works, and identify journals, articles and authors that PhD students value highly.     

Six guidelines for teaching intermediate macroeconomics

This is the first article that compares terminal master's degree programs in economics from universities that have a PhD program in economics with those that do not offer PhD programs in economics. The authors compare these differences based on surveys in 2002 and 2012. They examine differences in general program characteristics, department faculty, admission requirements, student characteristics, financial aid, and graduation and placement rates. They find statistically significant differences in all of these categories and also find that some of the differences and similarities have changed over time.     

Research Productivity in Business Economics: An Investigation of Austrian,German and Swiss Universities

Abstract. We draw on a new and comprehensive dataset that collects the research output of business economists employed by Austrian, German and Swiss universities. We compute research rankings of departments and identify the leading departments in selected subdisciplines. Moreover, we investigate how institutional design and individual characteristics affect research productivity and draw some conclusions for the training of junior scientists.     

Research Productivity in Business Economics: The Case of Marketing

Abstract. The German Economic Review ( GER ) recently published a paper by Fabel, Hein and Hofmeister about research productivity in Austrian, German and Swiss universities. The authors derive the rankings of institutions and subject areas by analyzing an impressive and comprehensive dataset, which captures the research output of business administration departments. While these rankings might hold at an aggregate level, they lack face validity at a subject-specific level. This lack of validity is demonstrated in the case of marketing by analyzing the research output of the top-ranked institutions in top-ranked journals. A number of proposals to overcome these kinds of problems are provided.     

The Institutional Concentration of Authors in Top Journals of Economics During the Last Two Decades

This paper addresses the institutional concentration of authors in 15 top economics journals from 1977 to 1997. The concentration of authors' PhD affiliations is substantially higher than the concentration of authors' current affiliations. Relating input indicators, such as population, number of universities with economics departments, or manpower in economics, to publication output reduces the US dominance considerably, whereas Israel and the United Kingdom come out excellently. Exporters and importers of PhDs among universities are identified. Concentration ratios like the Herfindahl-Index lack a clear time trend. Nevertheless, the position of the United States has been weakening in recent years.     

The allocation of PhD enrolment quotas in China’s research-oriented universities based on equity and efficiency principles

PhD enrolment quota allocation proves the key concern for China’s universities to promote institutional reform and improve research level, and it is often characterized by the zero sum game among schools within a university. Therefore, this article develops a new indicator system for PhD enrolment quota allocation and efficiency evaluation in China, and then it reallocates the quotas considering the preferences of decision-makers and the efficiency based on the historical data during 2011–2015 in a research-oriented university in China. The results indicate that, first, the preferences of decision-makers in the university for article publications and research funds may significantly affect the allocation of PhD enrolment quotas among schools. Second, when the linear combination weighting method is used, the overall efficiency for PhD enrolment allocation proves the highest, among various weighting methods concerned. Finally, to improve the overall efficiency of the 19 schools, five social science schools and four engineering schools have to cut their PhD enrolment quotas; among them, three engineering schools should reduce the largest redundant quotas sharply. The methods and results in this article are conducive to the allocation of education resources which have the zero sum feature and are often accompanied with undesirable outputs.     

Gender Differences in Research Patterns Among PhD Economists

This study is based on a 1996 survey of PhD economists working in the academic and nonacademic sectors since 1989. Despite a raw gender difference in all types of research output, the male dummy variable proves statistically significant in predicting only one publication measure. In a full sample and faculty subsample, number of years since receipt of PhD, publication in a refereed journal as a graduate student, and the total number of presentations made in professional forums were consistently, positively related to research productivity. The importance of other independent variables varies by research output. Typically unavailable variables such as workload, time use, submissions data, and family circumstances are also examined.     

Profitability and accumulation in Greek manufacturing

This paper examines long-term trends in profitability and capital accumulation for the Greek manufacturing industry from 1955 to 1989, using the growth accounting framework introduced by Weisskopf (1979) and further developed by Glyn et al. (1990). The results show that the overall 7% annual decline in profit rate in Greek manufacturing is attributed primarily to falling profit share and secondarily to falling productivity of capital. The effect of capacity utilization was negligible. The analysis is carried out for different subperiods and the relative importance of each of the constituent components of profitability is evaluated.     

ECONOMIC PERFORMANCE AND PUBLIC INFRASTRUCTURE: AN APPLICATION TO GREEK MANUFACTURING

To comprehend the impact of public infrastructure on economic performance this paper provides a measure of productivity growth as derived from duality theory. This productivity growth is decomposed into the components of technical change, returns to scale and the effects of public infrastructure, the variable of our interest. In an application, we opt for Greek manufacturing so as to investigate whether the decline in its growth rate is partly explained by public infrastructure. Despite some variation in the estimation results of shadow shares across industries, public infrastructure asserts a cost saving effect in most industries, though it also appears that traditional labour‐intensive industries with lower level of technological advancement do not benefit from the provision of public infrastructure. The estimation results further demonstrate that while public infrastructure enhanced productivity growth over the sample period for most industries, low infrastructure investment in the 1970s and the 1980s undermined productivity growth.     

Assessing the returns to collaborative research: Firm-level evidence from Italy

We use firm-level data from Italian manufacturing firms to assess the relationship between various types of R&D and total factor productivity growth, including collaborative research with other firms and universities. A novel twist to our empirical analysis is that we estimate a sample selection model, which allows us to treat the decision to conduct R&D as endogenous. We find strong evidence of positive returns to collaborative research with other companies, whereas collaborative research with universities does not appear to enhance productivity. This result implies that firms may conduct R&D with universities when appropriability conditions are weak and the outcomes of such research projects do not yield direct strategic benefits.     

Cointegration Tests of the Profit-maximising Equilibrium in Greek Manufacturing: 1958–91

This paper applies the recently developed cointegration techniques to test for a long-run equilibrium among real wages and the average productivity of labour as implied by profit maximisation in the Greek manufacturing sector. We find evidence for a profit-maximising equilibrium and for adjustment towards this long-run equilibrium through nominal wages and labour productivity. We have also provided an estimate of the elasticity of substitution of 0.23 which is consistent with that of other studies using alternative approaches.     

The Status of Econometrics in the Economics Major: A Survey

In this article, the authors describe the place of econometrics in undergraduate economics curricula in all American colleges and universities that offer economics majors as listed in the U.S. News & World Report “Best Colleges 2010” guide (U.S. News & World Report 2009). Data come from online catalogs, departmental Web sites, and online course syllabi. About one-third of the schools require econometrics of all students majoring in economics, about half require it of none, and a sixth require it of some, but not all, economics majors. Among universities with economics PhD programs and liberal arts colleges, almost all those ranked in the top 10 require it. Below the top 10, there is little correlation between ranking and econometrics requirements. Liberal arts econometrics classes are much more likely to require research projects than their counterparts in universities.     

Misleading Rankings of Research in Business

Abstract. The attempts by Schulze and colleagues and Ritzberger to develop a joint ranking of journals for economics and business research are critically evaluated. Their lists suggest that the quality of top business journals is substantially lower than that of many economics journals. If, however, the authors of these lists do not want to claim a general superiority of one discipline (economics) over another one (business), they should give a clear indication that these lists are only applicable for economists. This warning appears to be necessary because Fabel and colleagues derive a ranking of universities and departments with respect to research productivity in business from the business research discriminating list RbR_IMP by Schulze and colleagues. While Diamantopoulos and Wagner already show a lack of face validity of these results, this article explains that the reason for this lies not only in the downgrading and also biased weighting of the business journals across subfields, but even more importantly, in a remarkable incompleteness of the database.

Do education quality and spillovers matter? Evidence on human capital and productivity in Greece

This paper estimates production functions for Greek regions over 1971–2011, using census data on educational human capital. We construct rich human capital series, where data for employees are decomposed according to their education level. In addition, we take into account possible effects due to education quality and spillovers. Our evidence shows that human capital has a strong positive association with labor productivity through upper secondary and tertiary education, while primary education exhibits a negative relationship and lower secondary education does not exhibit any association with productivity. Tertiary education spillovers along with a number of education quality indicators present a significant positive relationship with productivity. Overall, findings suggest that policy makers should account for education quality as well as spillovers and direct their efforts toward a more efficient and enhanced education system with emphasis on high education levels to improve labor productivity overall and reduce spatial productivity disparities.     

Economics research in Canada: a long-run assessment of journal publications

Abstract.  We examine the publications of authors affiliated with an economics research institution in Canada in (1) the Top-10 journals in economics according to journals' impact factors, and (2) the Canadian Journal of Economics . We consider all publications in the even years from 1980 to 2000. Canadian economists contributed about 5% of publications in the Top-10 journals and about 55% of publications in the Canadian Journal of Economics over this period. We identify the most active research centres and identify trends in their relative outputs over time. Those research centres successful in publishing in the Top-10 journals are found to also dominate the Canadian Journal of Economics . Additionally, we check the robustness of our findings with respect to journal selection, and we present data on authors' PhD origin, thereby indicating output and its concentration in graduate education.     

Are Native and Non‐Native English Speaking Tutors Equally Effective?

Many studies find a negative effect of non‐native English speaking instructors on students' performance in universities where the language of instruction is English. However, the negative effect observed in the existing literature is not found in the study by Fleisher, Hashimoto and Weinberg (2002) , which uses the sample of instructors who received training in the Ohio State University's PhD programme. In many economics departments in Australia, mainly because their PhD programmes are not large enough, it is unrealistic to have all the tutors trained in the methods recommended in Fleisher, Hashimoto and Weinberg (2002) . This gives rise to a potential negative impact of non‐native English speaking tutors on students' performance. Nevertheless, by analysing the panel data drawn from first‐year quantitative methods, microeconomics and macroeconomics courses in an Australian university, we find no statistically significant difference in the effectiveness of small class teaching between native and non‐native English speaking tutors.     

Origin of FDI and Intra‐Industry Domestic Spillovers: The Case of Greek and European FDI in Bulgaria

This paper uses firm‐level data to assess the horizontal impact of foreign firm ownership on domestic productivity in Bulgaria. We identify a theoretical tradeoff between technological distance (of domestic versus foreign firms) and internalization capacity (of spillovers) and examine the extent to which this is reflected in the impact on the domestic economy of different types and origins of FDI. Emphasis is placed upon the effects of Greek FDI, which is known to be of a distinctively “regional” character. We find that Greek FDI produces significantly larger positive spillovers, which appear more suitable for the Bulgarian context of transition and economic restructuring. We also unveil some notable “hysteresis” and “technology bias” effects for FDI spillovers of all origins, as well as some country‐specific ownership‐structure and threshold effects.
