Trends in undergraduate economics degrees, 2001–2018

Undergraduate degrees awarded in economics by U.S. colleges and universities were stagnant from 2010 (2009–10) through 2013, increased rapidly (almost 15%) over the two years from 2013 through 2015, but have subsequently leveled off in 2016 through 2018.     

Unconditional quantile regressions,wage growth and inequality in the Philippines, 2001–2006: the contribution of covariates

I implement a two-stage procedure to estimate the components of real wage change in the Philippines along the wage distribution from 2001 to 2006, as well as the contribution of individual covariates to each component. The methodology is based on Re-centred Influence Functions (RIF), as suggested by Firpo et al. (2009). The advantage of this methodology is that it not only decomposes the unconditional wage change at any quantile of the wage distribution, but also allows the characterization of the contribution of any single covariate on each component. I find that real earnings of males in the Philippines declined and the decline along the earnings distribution is generally higher at higher deciles for all males and higher at lower deciles in Manila. Decomposition results are driven by the wage structure component, while the composition effect is small and generally positive with education as the main contributor. Within the wage structure effect, the main determinants are associated with changes in the rewards of experience and occupation, along with residual change (change in intercepts).     

Grand strategies and strategic actions in the pharmaceutical industry 2001–2002

This paper explores the strategic actions realised by firms in the pharmaceutical industry during 2001 and 2002. The purpose was to develop an empirically derived categorisation of strategic actions and grand strategies from the behaviour of firms that could be used as the basis of a methodological framework for developing understanding of strategic change. Qualitative analysis was used to identify and categorise strategic actions implemented by pharmaceutical firms. Twenty-three grand strategies were identified and are described. Implications for further research in strategy development are discussed.     

Spatial analysis of urban growth in Spain, 1900–2001

The purpose of this paper is to improve the knowledge of the Spanish urban system. We study the evolution of population growth among the group of 722 municipalities included in the Spanish urban areas over the period 1900–2001. A spatial SUR model is estimated for Zipf’s law and shows the existence of two main phases: divergence (1900–1980) and convergence (1980–2001). Then, the cross-sectional distribution of urban population is characterized by means of nonparametric estimations of density functions and the growth process is modeled as a first-order stationary Markov chain. Spatial effects are finally introduced within the Markov chain framework using regional conditioning. This analysis shows a low interclass mobility, i.e., a high-persistence of urban municipalities to stay in their own class from one decade to another over the whole period, and the influence of the geographical environment on urban population dynamism. Previous versions of this paper were presented at the 45th Congress of the European Regional Science Association (Vrije Universiteit, Amsterdam, Netherlands, August 23–27, 2005) and at the International Workshop on Spatial Econometrics and Statistics (Rome, Italy, May 25–27, 2006). We would like to thank two anonymous referees, M. Bosker, P. Cheshire, A. Carrington, B. Fingleton, R. Guillain, E. Lopez-Bazo, J. Paelinck and the other participants of these meetings for their valuable comments. Coro Chasco acknowledges financial support from the Spanish Ministry of Education and Science SEJ2006-14277-C04-01.

Inventory investment in the United States, 1920–1941

An inventory investment function for the inter-war period in the United States is estimated using recently published quarterly data. The estimates obtained are consistent with plausible lag structures. An increase (decrease) in sales causes unplanned inventory decumulation (accumulation) in that quarter but by the end of a year more than half of the adjustment of inventories to a new equilibrium is complete.     

Divorce and the Birth Control Pill in the US, 1950–85

This paper explores the relationship between the advent of the birth control pill and divorce rates. Women using the pill can decide when and whether to have children and whether to maintain their attachment to the labor force. This ability may increase women's autonomy, making divorce more feasible. The pill's effects are identified through a quasi-experiment exploiting differences in the language of the Comstock anti-obscenity statutes approved in the late 1800s and early 1900s in the United States. Empirical evidence from state-level data on US divorce rates 1950 to 1985 shows that sales bans of oral contraceptives have a negative impact on divorce. These findings are robust to alternative specifications and controls for observed (such as women's labor force participation) and unobserved state-specific factors, and time-varying factors at the state level. Results suggest that the impact of women's control of hormonal contraception on their autonomy is important in divorce decisions.     

Four scenarios for nanotechnologies in the UK, 2011–2020

The future social value of nanoscale science and technology (NST) has been repeatedly represented as revolutionary. However, government and industry support for the commercialisation of NST has to confront four key areas of uncertainty: concerning potential hazards associated with applications, commercial viability, public acceptance and evolving regulation. Academic and policy responses have to date largely emphasised the need for adaptive and anticipatory regulation, yet research which evaluates the prospects of success in implementing such measures has so far been lacking. This paper contributes to remedying this lack by examining difficulties and opportunities which may arise around this regulatory agenda in the UK, with the aid of a ‘policy Delphi’ exercise undertaken with a multi-stakeholder panel. It summarises four scenarios to aid policy-makers and technology strategists in the UK and internationally in thinking through how the future of NST innovation may be affected by factors associated with the aforementioned areas of uncertainty.     

An Empirical Investigation of the Ratchet Effect in the OECD, 1985–2009

This paper employs a reduced form structuralist model of inflation in the OECD over the period 1985–2009 to find out whether domestic prices respond symmetrically to rising and falling import prices. We find that the response is asymmetrical: domestic prices rise when import prices rise but they do not fall when import prices fall. Our finding thus confirms the presence of a ratchet effect in the sample countries during the sample period, and implies that factors – such as exchange rate fluctuations and movements in tariff rates – that influence import prices tend to be inflationary.     

Estimation of the Natural Unemployment Rate in the Russian Federation, 1994–2004

To specify the problem of unemployment in Russia, we estimate the natural rate of unemployment by consecutively estimating the optimal size of the labour force and the optimal employment. For estimation of the optimal values we used a modified Hodrick–Prescott filter technique. The results show that the natural rate of unemployment in Russia during 1994–97 was stable around 13–13.5% and decreased to 7.1% by mid-2004. Moreover, before 1998 the actual unemployment was significantly lower than the natural rate and today practically equals it.     

Common Trends and Common Cycles in Per Capita GDP: The Case of the G7 Countries, 1870–2001

In this paper we analyze per capita incomes of the G7 countries using the common cycles test developed by Vahid and Engle (Journal of Applied Econometrics, 8:341–360, 1993) and extended by Hecq et al. (Oxford Bulletin of Economics and Statistics, 62:511–532, 2000; Econometric Reviews, 21:273–307, 2002) and the common trend test developed by Johansen (Journal of Economic Dynamics and Control, 12:231–254, 1988). Our main contribution is that we impose the common cycle and common trend restrictions in decomposing the innovations into permanent and transitory components. Our main finding is permanent shocks explain the bulk of the variations in incomes for the G7 countries over short time horizons, and is in sharp contrast to the bulk of the recent literature. We attribute this to the greater forecasting accuracy achieved, which we later confirm through performing a post sample forecasting exercise, from the variance decomposition analysis.

Stolper-Samuelson-Rybczynski in the Pacific: Real wages and real exchange rates in the Philippines, 1956–1978

The paper attempts to explain movements of real wages in the Philippines in terms of the standard trade-theoretic Stolper-Samuelson-Rybczynski model. In view of the factor intensities in the Philippines, commodities are aggregated into two composite goods — traded and non-traded — whose relative price — the so-called ‘real exchange rate’ — is shown to have been an important determinant, with changes in relative factor supplies of less importance in determining real wages. A conventional two-sector model is set out, which distinguishes between the short and long run effects in terms of the ‘quasi-fixity’ of sector specific capital. A simple regression model is estimated and seems to provide a fairly good explanation of what has hitherto appeared to be a puzzling feature of post-war Philippines economic performance — high growth rates of output and employment, accompanied by declining real wages (in turn being associated with a rising incidence of poverty) in at least two periods.     

A tale of two Ginis in the US, 1921–2012

Following a methodology by Jantzen and Volpert (2012), we use IRS Adjusted Gross Income data for the US (1921–2012) to estimate two Gini indices representing inequality at the bottom and the top of the income distribution, and to calculate the overall Gini as a function of the parameters underlying the two indices. A steady increase in the overall Gini since the Second World War actually hides two different periods of distributional changes. First, the increase in inequality from the mid 1940s to the late 1970s is driven by rising inequality at the bottom of the income distribution that more than offsets a decrease in inequality at the top. The implication is that middle-income earners gained relative to high-incomes, and especially relative to low-income earners. Second, the rise in the Gini after 1981 is driven by rising inequality at the top. Third, top-driven inequality follows a U-shaped trajectory consistent with Piketty and Saez (2003, 2006). Fourth, the welfare effects of the different distributional changes behind increasing inequality can be evaluated in light of the Lorenz-dominance criterion by Atkinson (1970): we argue that the rise in inequality since 1981 is much more likely to be associated with a social welfare loss net of compensating growth.     

Income mobility and the middle class in Russia, 1995–2007

This article analyzes the determinants of income mobility between 1995 and 2007, using the Russia Longitudinal Monitoring Survey (RLMS-HSE). The analysis uses the mixture model method and is carried out between and within income groups, defined on the basis of household income. The results of the within-group analysis suggest that the probability of remaining in the middle of the income distribution is greater than that of remaining poor or rich. However, if a household moves away from the middle group, the probability of falling into the bottom group is much higher than that of moving upwards.     

The time structure of production in the US, 2002–2009

The US time structure of production during the 2002 through 2009 business cycle is characterized empirically using industry-level input-output data. An industry’s total industry output requirement (TIOR) is proposed as a metric for “roundaboutness”. I find that the time structure of production lengthened following the Federal Reserve’s 2002 expansionary deviation from the Taylor rule and then contracted during the Great Recession. Value added growth in the most-roundabout of US industries accelerated relative to that of the least-roundabout industries. Heading into the Great Recession, value-added growth in the most-roundabout industries contracted early and turned negative in 2007 while value-added growth in the least-roundabout industries remained positive until 2009. The stylized facts of the time structure of production are consistent with Austrian Business Cycle Theory.     

Electrification,the Smoot-Hawley Tariff Act and the Decline in Investment Expenditure in 1931–1932: Testing the Excess-Capacity Hypothesis

Beaudreau (1996) argued that the decline in investment expenditure in the early 1930s was the result of two factors, namely the electrification of U.S. manufacturing in the 1910s and 1920s which had resulted in significant excess capacity, and secondly, to the failure of the Smoot-Hawley Tariff Bill in October 1929 to be passed by the Senate, resulting in (i) the Stock Market Crash in October 1929 and (ii) the ensuing precipitous decline in investment expenditure which touched off the Great Depression. In short, the manufacturing sector in the late 1920s found itself with excess capacity, prompting Senator Reed Smoot and the Republican Party to propose another upward revision of the tariff schedule. The failure to deliver on this promise led to the Crash and the ensuing decline in investment expenditure, the cumulative effect of which led to the Great Depression. This paper tests this hypothesis using two-digit industry investment data. As electrification varied considerably across industries it would stand to reason that sectors that electrified the most would have witnessed the largest decreases in investment expenditure (plant and equipment), owing to the presence of excess capacity. The results confirm this hypothesis, leading us to conclude that electrification-based excess capacity may have been an important cause of the downturn in 1930 and 1931.     

The dynamics of regional unemployment in the UK, 1974–89

This paper investigates the relationship between regional and national unemployment for the UK for the period 1974–1989. This problem is approached by using the time-series methods of cointegration and causality tests. The main conclusions are that regional and national unemployment are not as closely related as might have been supposed although any causation may, as previously assumed, run from the national to the regional level. Some regions are seen to be changing their position in the hierarchy of relative regional unemployment while most retain their relative status.     

The Determinants of Tying Litigation, 1961–2001

The idea that changes in Supreme Court decision rules should have measurable effects on the volume of cases litigated has a compelling plausibility, and several models of litigation predict this result. The prediction is a fragile one, however, because it implies very restrictive assumptions about the probability distributions of the cases subject to dispute. The period studied includes four Supreme Court decisions widely regarded as changing the rules and altering the level of uncertainty surrounding the legality of the anti-tying provisions of the antitrust laws. Broad trends in antitrust activity generally and changes in firm profitability statistically explain over three-quarters of the observed variation in tying litigation. Changes in legal precedent have only modest effects upon litigation.

Real wages,productivity and economic growth in the G7, 1960–2002

Abstract

This paper investigates empirical real wage and productivity dynamics in the G7 countries using annual data for 1960–2002. The findings suggest that the level of labor productivity is positively related to GDP growth in all countries, and real wages are positively related to growth in some of them. The results tend to confirm the ‘profit paradox’. This postulates a positive relationship between economic growth and the aggregate profit share, and suggests that the frequent support of business interests for deflationary economic policies is a puzzle.
