Cost structure,productivity and efficiency of the Italian public higher education industry 2001–2011

In this paper, I analyze the cost structure of the Italian higher education system for the decade between 2001 and 2011, by means of a stochastic translog cost function. I suggest that the judgment about the optimal configuration of the sector is strongly dependent upon the policy priorities set by decision makers. When assuming that the universities’ output is the number of students, scale economies are exhausted, and marginal costs are relatively low; when considering graduates as outputs instead, there is opportunity for increasing the scale of operations. Inefficiency affects production in a sensible manner, especially when assuming that the target output is the number of graduates. Moreover, efficiency contributes to explaining a relevant portion of the productivity increases in the period. No significant scope economies between teaching and research emerge, suggesting that a higher degree of universities’ specialization can be a direction for improving the sector’s efficiency and productivity.     

Economic integration and regional convergence: effects of NAFTA on local convergence in Mexico, 1980–2008

Continental integration processes can alter traditional development axes. Paelinck and Polèse´s work in 1999 explains that in the case of Mexico there is a tension between the U.S. border and the rest of the country: Mexico´s integration in the NAFTA should have reduced the U.S. border attraction, extending the growth to territories located between this border and Mexico City. To test this hypothesis, we propose a spatial conditional β-convergence model that uses as regressors both the distances to the U.S. border and to Mexico City, together with other control variables. This model is applied to the period from 1980 to 2008 using GVA at the municipality level. Working with municipal-level data allows to observe convergence patterns across space and identify the effects of location. The time-span studied distinguishes between before and after NAFTA. Estimates based on Mundlak´s approach were obtained for time-invariant regressors. Results show that during the pre-NAFTA period there was a general process of convergence, but it is mainly explained by the faster growth of municipalities located near to the U.S. border. However, post-NAFTA, convergence in municipalities disappeared and the effect of distance to the U.S. border reversed its sign, as predicted in Paelinck and Polèse´s model.     

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.     

The urban–rural divide,regional disaggregation and the convergence of crime

Potential regional variation in crime rates has been recognized as an issue of clear importance given its implications for the development and evaluation of theories of criminal activity, determining the appropriate level of disaggregation at which to undertake empirical analyses of crime and whether crime fighting policies should be constructed at a national or local level. Consequently, a literature has evolved examining the similarities in US regional crime rates and whether a national trend exists or is emerging. The present article extends the recent research into the emergence of a national trend by considering convergence in alternative classifications of crime using a data set subject to a higher degree of disaggregation than considered hitherto. The results obtained overturn previous findings obtained using more highly aggregated data, indicating the detection of convergence to be dependent upon the level of disaggregation considered. In addition, the extent of convergence detected is shown to vary across classifications of criminal activity and reflect anecdotally noted changes in the evolution of crime at a national level. The implications of the observed regional variation in crime for the urban–rural divide and theoretical, empirical and policy analyses are noted.     

Growth Convergence and Regional Inequality in India (1981–2012)

There has been significant research effort to study the impact of liberalisation on growth and distribution in India. Using per capita income (PCI) data for the period 1981–82 to 2012–13 (28 regions for the entire period and 31 regions for 2001–2 to 2012–13) at the sub-national level in India we examine the claims of divergence and stratification (twin peak formation) as has been claimed in some of the recent literature. We confirm that there is divergence of PCI. We present the first set of tests of multimodality in the Indian convergence debate using Silverman (J R Stat Soc 43:97–99, 1981; Density estimation for statistics and data analysis. Monographs on statistics and applied probability, Chapman & Hall, London, 1986) procedure. Weighted kernel density plots and multi-modal tests reveal that there is emergence of “multi-modes” in the distribution of PCI, not just twin modes. The spatial pattern of growth reflects an area of stagnation in the eastern-central belt—Bihar, Madhya Pradesh, Uttar Pradesh and Orissa, and in the north eastern part of India—Assam and Manipur and a decline in Mizoram. Sikkim demonstrates fastest growth, whereas Gujarat, Haryana, Kerala, Maharashtra, Punjab, Tamil Nadu (among the big states) and Himachal Pradesh, and Andaman and Nicobar (small state and Union Territories) maintained their position. Karnataka, and Andhra Pradesh (among the southern states), Arunachal Pradesh and Nagaland (among the north eastern states) along with Jammu and Kashmir, Uttarakhand and Chhattisgarh, moved up in the growth ladder. The continuation of growth stagnation in most of the BIMARU states poses a challenge to received theories of growth convergence and raises developmental concerns that the increased play of market forces in the Indian economy have not been able to overcome.

     

Surplus measures and luenberger Hicks–Moorsteen productivity indicator

This paper extends to production theory some notions of compensated and equivalent variation analyzed in Luenberger (Econ Theory 7:445–462, 1996) in a consumer context. Along this line the Luenberger–Hicks–Moorsteen productivity indicator introduced in Briec and Kerstens (Econ Theory 23:925–939, 2004) is derived from these concepts for multi-output production technologies. The dual properties of this productivity indicator are analyzed and an aggregate indicator is introduced inspired from the resource function proposed in Luenberger (1996). A connection to a suitable Slutsky matrix is established.     

Assessing measurement errors in the CDM research–innovation–productivity relationships

ABSTRACT

The Crépon-Duguet-Mairesse 1998 article, known as CDM, initiated a structural econometric framework to analyze the relationships among research, innovation and productivity, which has been estimated most generally on the basis of cross-sectional innovation survey-type data. Some econometric implementations of the CDM approach have suggested that such data give useful but imprecise measures of the innovation output (share of innovative sales), and to a lesser degree of the innovation input (R&D). These ‘measurement errors’ may result in attenuation biases of the estimated R&D and innovation impact elasticities in the two basic CDM ‘roots’ relations of R&D to innovation and innovation to productivity, as well as in the extended production function à la Griliches linking directly R&D to productivity. Using a panel of three waves of the French Community Innovation Survey (CIS), we assess these biases and the magnitude of the underlying measurement errors, assuming mainly that they are ‘white noise’ errors. We do so by comparing two pairs of usual panel estimators (Total and Between) in both the cross-sectional and time dimensions of the data (Levels and Differences). We find large measurement errors on innovation output in the innovation–productivity equation, resulting in large attenuation biases in the related elasticity parameter. We also find smaller but sizeable measurement errors on R&D, with significant attenuation biases in the corresponding elasticity estimates, in the R&D–innovation equation and the extended production function. Simulations suggest that the measurement errors on innovation and R&D are unaffected by similar measurement errors on the capital variable.     

Causes of world trade growth in agricultural and food products, 1951–2000: a demand function approach

The objective of the present study is to analyse the causes of the growth of international agricultural and food trade in volume terms from 1951 to 2000. The results suggest that income growth has been the principal reason for this expansion, while exchange rate stability and the real price of agricultural products played only a minor role. Multilateral trade liberalization and trade costs, given their long-term stability, are not elements that could have stimulated their growth. Finally, the intensive liberalization of trade which took place in various economic regions, especially in Europe, became a key factor in promoting agricultural trade among the countries participating in regional trade agreements. The study results also indicate that the determinants of trade growth for these goods were different to those for other goods and other periods.     

The distribution of income in Sri Lanka in 1969–1970 and 1980–1981: A decomposition analysis

In 1977 the Sri Lankan government implemented a comprehensive policy of economic liberalization, removing many government controls on the economy and providing incentives for both foreign and domestic investment. The previous policies were often justified as necessary to maintain an equitable distribution of income. Income data from 1969–1970 and 1980–1981 surveys indicate that inequality has increased, but these data are shown to be unreliable for drawing conclusions on changes in the distribution of income. Expenditure data from the same surveys indicate that inequality has declined in the 1970's, both in the economy as a whole and within all sectors and ethnic groups.     

Are wages and productivity converging simultaneously in Euro-area countries?

A convergence analysis is applied to wages and productivity for Euro-area countries in the period from 1981 to 2001. The results show a reduction in the dispersion of wages and unit labour costs, but not in productivity. Different patterns are found for real and nominal wages: higher levels of inflation in countries with higher growth rates of unit labour costs have caused nominal wages to move towards equalization. Moreover, disparities in all the variables have remained more or less the same since 1997, suggesting that the establishment of a single currency area has not accelerated the process of wage equalization.     

An index number framework for explaining changes in input productivity– an application to energy efficiency

Lott (2009) finds that nonvoted ballot rates for down-ballot races are greater than those for presidential races, and newer technologies that reduce nonvoted presidential ballots create even greater rates of nonvoting down-ballot than the same older voting technologies. The conclusion is momentous: adopting voting technologies that minimize under-voting in presidential races actually increases under-voting across all races on the same ballot. This study extends Lott's by examining the Congressional vote on the Help America Vote Act of 2002 (HAVA 2002), which established a program to provide funds to states in order to replace punch card voting systems with newer technologies. We focus on the racial component of Lott's finding, specifically that Hispanic-American voters exhibit greater rates of voter fatigue than do white voters. This study posits that, given the large Hispanic-American populations in California and Texas and their propensity to support Democrats in these states, House Democrats from these states would not view the HAVA 2002 as favourably as House Democrats from other parts of the US. Among other results presented here, the data show that support for HAVA 2002 among California and Texas House Democrats was 11.6 percentage points below that of House Democrats from the other 48 states.     

Profitability efficiency,marketability efficiency and technology gaps in Taiwan’s banking industry: meta-frontier network data envelopment analysis

The aim of this article is to measure the profitability efficiency (PE) and marketability efficiency (ME) of non-homogenous Taiwanese banks after the adoption of International Financial Reporting Standards by using the convex meta-frontier data envelopment analysis model. The model is applied to simultaneously estimate PE and ME of the banks in financial holding companies (FHCs) and the banks not in FHCs. The meta-inefficiencies in individual processes are further decomposed into group inefficiencies and technology gap inefficiencies to explore the sources of inefficiency. The empirical results indicate that the banks in FHCs can reduce more costs than the banks not in FHCs, whereas the banks not in FHCs can create greater market value than the banks in FHCs. For the banks joining and not in FHCs, technology gap inefficiency is the main source of inefficiencies in both profitability and marketability processes.     

Investment–productivity dynamics and distribution dynamics in a multisector economy: some theory and an application to Italian regions

In this paper, we study the investment–productivity dynamics in the Framework Space, presented by Böhm and Punzo [Cycles, Growth and Structural Change, Routledge, London (2001) 47], as the distribution dynamics of the production sectors of an economy. We apply such theoretical framework to data from Italian regions to identify differences in sectoral behaviors both within and across regions. Our main findings are: sectors within a region generally follow different regime dynamics; Southern Italian regions are generally characterized by higher degrees of heterogeneity in sectoral growth behaviors and of regime instability. Also, we find support to the hypothesis of a positive relation between this type of instability and unemployment, as argued by the Neo-Austrian theory of structural dynamics.     

Technological and non-technological innovation and productivity in services vis-à-vis manufacturing sectors

In this paper, the links between investment in innovation activities, innovation outputs (technological and non-technological innovation) and productivity in services vis-à-vis the manufacturing sector are explored using innovation survey data from Uruguay. The size of firms, their cooperation in R&D activities, the use of public financial support, patent protection and the use of market sources of information are very important drivers of the decision to invest in innovation activities across sectors. The main determinants of technological and non-technological innovations are the level of investment in innovation activities and the size of the firm. The results indicate that both technological and non-technological innovations are positively associated to productivity gains in services, but non-technological innovations have a more important role. The reverse happens for manufacturing, where technological innovations are more relevant for productivity.     

Firms’ efficiency,exits and government procurement contracts

This study shows that productivity trends in Russia are similar to those in other countries where technology leaders enjoy productivity growth, with a gap increasing between them and other companies. The survival analysis suggests that the most efficient firms quit the market at a faster rate than other companies do. Survival functions of the least efficient firms do not always differ significantly from those of other enterprises. Additional financial support from government contracts helps firms in all efficiency groups survive but this effect is stronger for laggards. The shift of gains from the public procurement system towards low productive firms leads to the distorted allocation of resources in the economy and, in the long run, may undermine economic growth by allowing inefficient companies to stay in the market significantly longer than would be the case in a more competitive environment.     

Health-related quality-of-life,work productivity,and economic burden among patients with Parkinson’s disease in Japan

Abstract

Aims: This study aimed to characterize the burden of Parkinson’s disease (PD) by examining health-related quality-of-life (HRQoL), impairments to work productivity and daily activities, healthcare resource use, and associated costs among Japanese patients with PD.

Materials and methods: This retrospective cross-sectional study used data from the 2009–2014 Japan National Health and Wellness Survey (NHWS) (n?=?144,692). HRQoL (Short Form 36-Item Health Survey version 2), impairments to work productivity and daily activities (Work Productivity and Activity Impairment Questionnaire), healthcare resource utilization, and annual costs were compared between respondents with PD (n?=?133) and controls without PD (n?=?144,559). The effect of PD on outcomes was estimated using propensity score weighting and multivariable regression models.

Results: HRQoL was lower in patients with PD compared to the control group, with reduced physical (41.3 vs 51.3) and mental (35.7 vs 45.4) component summary scores and health state utility scores (0.62 vs 0.77; p?<?.001 for all). Patients with PD also reported higher levels of absenteeism (19.3% vs 3.3%), presenteeism (45.2% vs 18.5%), overall work impairment (52.8% vs 20.3%), and activity impairment (49.6% vs 20.8%) than controls without PD (p?<?.001 for all). In addition, patients with PD had higher healthcare resource utilization, direct (¥3,856,921/$37,994 vs ¥715,289/$7,046), and indirect (¥2,573,938/$25,356 vs ¥902,534/$8,891) costs compared with controls without PD (p?<?.001 for both).

Limitations: Data were cross-sectional and did not allow for causal inferences. Although the NHWS demographically represents the Japanese adult population, it is unclear whether it adequately represents the adult population with PD in Japan.

Conclusions: PD was associated with poorer HRQoL, greater work productivity loss, and higher direct and indirect costs. The findings suggest that an unmet need exists among patients with PD in Japan. Improving PD treatment and management could benefit both patients and society.     

Do export and technological specialisation patterns co-evolve in terms of convergence or divergence? Evidence from 19 OECD countries, 1971–1991

Several researchers looking at the development of international export specialisation patterns have shown that there is a weak tendency for OECD countries to exhibit decreased levels of specialisation. This finding is in contrast to findings made by other authors, who found increasing technological specialisation. The first aim of this paper is to investigate whether these contradictory findings are due to a `real world' phenomenon, or whether the explanation is purely technical, by comparing the development of export specialisation to specialisation in terms of US patents, using the same methodology and level of aggregation. The second aim is to analyse the extent to which countries and sectors display stable specialisation patterns over time, also both in terms of exports and in terms of technology. The paper confirms that the OECD countries tend in general to become less specialised in terms of exports. The evidence is less conclusive with regard to technological specialisation, as the results are mixed in the sense that just about half of the countries tend to exhibit increased levels of specialisation, while the other half tend to exhibit lower levels of specialisation. In terms of country and sectoral stability of specialisation patterns, it can be concluded that both trade specialisation and technological specialisation patterns are path-dependent. In comparison, however, trade specialisation patterns are more stable than are technological specialisation patterns.     

Environmental efficiency and labour productivity: Trade-off or joint dynamics? A theoretical investigation and empirical evidence from Italy using NAMEA

In this paper we test an adapted EKC hypothesis to verify the relationship between ‘environmental efficiency’ (namely emissions per unit of value added) and labour productivity (value added per employee). We exploit NAMEA data on Italy for 29 sector branches and 6 categories of air emissions for the period 1991-2001. We employ data on capital stock and trade openness to test the robustness of our results.On the basis of the theoretical and empirical analyses focusing on innovation, firm performances and environmental externalities, we would expect a positive correlation between environmental efficiency and labour productivity — a negative correlation between the emissions intensity of value added and labour productivity — which departs from the conventional mainstream view. The hypothesis tested is a critical one within the longstanding debate on the potential trade-off or complementarity between environmental preservation and economic performance, which is strictly associated with the role of technological innovation. We find that for most air emission categories there is a positive relationship between labour productivity and environmental efficiency. Labour productivity dynamics, then, seem to be complementary to a decreasing emissions intensity in the production process. Taking a disaggregate sector perspective, we show that the macro-aggregate evidence is driven by sector dynamics in a non-homogenous way across pollutants. Services tend always to show a ‘complementary’ relationship, while industry seems to be associated with inverted U-shape dynamics for greenhouse gases and nitrogen oxides. This is in line with our expectations. In any case, EKC shapes appear to drive such productivity links towards complementarity. The extent to which this evidence derives from endogenous market forces, industrial and structural change, and policy effects is discussed by taking an evolutionary perspective to innovation and by referring to impure public goods arguments.     

How important are human capital, physical capital and total factor productivity for determining state economic growth in the United States, 1840–2000?

This paper introduces new data on state-level physical capital by sector and land in the farm sector for the states of the United States from 1840 to 2000. These data are incorporated into aggregate accounting exercises with the aim of comparing cross-state results to those found in cross-country samples. Our aggregate results agree closely with the cross-country literature: input accumulation accounts for most of output growth, between three-fifths and three-quarters, but variation in the growth of TFP accounts for about three-quarters of the variation in the growth rate of output per worker. In convergence accounting, convergence of log TFP accounts for about seventy percent of the observed convergence in log output per worker.     

Authorship,Collaboration, Topics,and Research Gaps in Environmental and Resource Economics 1991–2015

Environmental and Resource Economics is one of the premier journals in the field of environmental economics. It was established with an aspiration to focus more on applied and policy relevant research compared to other established journals, and to establish better channels of communication and collaboration between researchers from Europe and other parts of the world. We present a text based exploratory analysis of 1630 articles published in the Journal from 1991 to 2015 that suggests the Journal has been somewhat successful in meeting both these aims. Perhaps more importantly, it shows the Journal continues to progress toward these goals. The European authors are the largest contributors to the Journal, which is in contrast to other prominent journals (such as Journal of Environmental Economics and Management and Ecological Economics). And while most of the collaboration has occurred within this geographic region (e.g., European authors collaborated with other European authors more frequently), this trend appears to be changing as the proportion of articles written by international collaborators is gradually increasing. Topic analysis reveals that almost all of the articles could be grouped under applied and/or policy relevant topics, and almost two-thirds of the articles are empirical in nature, which suggest that the journal has been able to fulfil both of its commitments. We also investigate trends in research foci over the last 25 years and what kind of research gaps can be discerned.
