DO LABOUR SOCIETIES PERFORM DIFFERENTLY TO COOPERATIVES? EVIDENCE FROM THE SPANISH BUILDING INDUSTRY

ABSTRACT: Labour Societies and Cooperatives are both Social Economy enterprises, but with noticeable differences, some of which are imposed by legislation in Spain. The aim of this paper is to study whether such differences affect their management capacity and, in particular, efficiency. In doing so, Data Envelopment Analysis techniques and the metafrontier approach proposed by O’Donnell et al. (2008) are used on a sample of Spanish Labour Societies and Cooperatives belonging to the building industry. Scores of technical efficiency and metafrontier ratios are computed at firm level and, as a novel contribution to existing literature in this field of research, at input‐specific level. The main finding shows that Cooperatives enjoy some technological advantages over Labour Societies, particularly in regard to the management of labour, fixed assets and current assets.     

HOW DID STATE‐OWNED BANKS RESPOND TO PRIVATIZATION? EVIDENCE FROM THE INDIAN EXPERIMENT

ABSTRACT ** : The paper examines the response of banks to privatization. Using data on all state‐owned banks for the period 1990–2006, the findings indicate that fully state‐owned banks are significantly less profitable than partially privatized ones. The improvements in performance by partially privatized banks are, in fact, sustained after privatization. In addition, the analysis indicates that privatization improves profitability, efficiency and improves bank soundness, while lowering bank risk. While the improvement in bank risk is typically spread out over a much longer period, the progress in terms of profitability and economic efficiency typically occurs in the post‐privatization period.     

WHAT DRIVES THE TIME‐SERIES AND CROSS‐SECTIONAL VARIATIONS IN BANK CAPITAL RATIOS? EVIDENCE FROM JAPAN

This paper documents the time‐series and cross‐sectional variations in bank capital ratios and investigates their underlying driving forces using listed Japanese bank data from 1977 to 2009. We derive an overall framework in the form of a present‐value model to decompose the variation in bank capital ratios into changes in expected future stock returns, profitability and leverage ratios. Moreover, we use the variance decomposition approach to examine the relative importance of these factors. We find that the expected future stock returns dominate the time‐series variation in bank capital ratios, and that the expected future profitability also plays an important role as the expected stock returns in the cross‐sectional variation.     

ARE LONG‐TERM INFLATION EXPECTATIONS WELL‐ANCHORED? EVIDENCE FROM THE EURO AREA AND THE UNITED STATES

This paper analyses the stability of long‐term inflation expectations and uncertainty, based on their sensitivity to innovations to observed inflation, short‐ and medium‐term forecast news. News is defined in a subjective sense and derived from revisions to shorter‐term fixed‐target forecasts. The assessment tests for presence of non‐linear effects, including regime changes during disinflation in the USA in the 1990s and the recent financial crisis. Stability is also investigated in terms of level evolution, based on a structural non‐linear and non‐Gaussian learning model to uncover the presence of a common trend underlying the long‐term dynamics of inflation, individual expectations, and uncertainty.     

ARE CONSUMERS MORE LOYAL TO NATIONAL BRANDS THAN TO PRIVATE LABELS?

The evolution of private labels (PLs) can be understood in terms of a strategy adopted by the retail industry with the aim of competing with national brands (NBs). In the 1990s, this strategy led to the development of ‘me too’ products, which currently represent the largest share of store brand products. Since the early 2000s, retailers have widened the range of their store brands by introducing high‐quality products. The aim of this study was to estimate consumers’ attachment to ‘me‐too’ and niche PLs respectively, as compared to NBs. We captured the degree of maturity of these PLs through their price‐elasticities, computed for three staple goods offered by three mass retail companies. It was found that price sensitivity does not differ much between the ‘me‐too’ PLs and the corresponding NBs. This result confirms that ‘me‐too’ products are now considered reliable quality brands. However, in the high quality segment, consumers remain more sensitive to the price of PLs than to that of NBs, a characteristic which may relate to their recent introduction on the market.     

ARE SURVEYS OF EXPERTS UNBIASED? EVIDENCE FROM COLLEGE FOOTBALL RANKINGS

Policymakers are frequently interested in soliciting unbiased information regarding alternative policies, and expert surveys can be influential. As ranking policies is an often subjective process, there is always the concern of bias, both intentional and not. Expert bias is difficult to discern in the policy world, but surveys of expert opinion are compiled and “tested” for accuracy weekly in college football, allowing for hypothesis testing. Although previous research has used college football rankings to determine the ability of surveys to incorporate relevant information, this article examines the Associated Press and American Football Coaches' Association rankings for evidence of systematic bias. Specifically, more than 1,300 games from the 2003 to 2008 regular seasons are tested for factors that are systematically correlated with upsets. Both polls predict the winner nearly 80% of the time, and although there is evidence of systematic conference bias, correcting the rankings would only improve the accuracy of the polls by about 1%. There is no evidence of a bias favoring “big market” teams, nor teams that have strong journalism programs or are from the East Coast. (JEL D4, L8)     

HOW ARE UPSTREAM TRANSFERS DETERMINED? NEW EVIDENCE FROM SOUTH KOREA

Exploiting new data from South Korea on intergenerational transfers made in regular and irregular intervals, I examine what determines and motivates upstream transfers. The results indicate that regular transfers are largely motivated by altruism, but that irregular and in‐kind transfers are unresponsive to parental economic need. The findings imply that public old‐age support would crowd out regular transfers to some extent. It is also found that roles are divided among siblings in supporting the elderly parents: the eldest married son is likely to transfer regularly and the most, whereas the other siblings transfer irregularly or in‐kind.     

ARE LABOUR FORCE PARTICIPATION RATES NON‐STATIONARY? EVIDENCE FROM 130 YEARS FOR G7 COUNTRIES*

This paper applies a unit root test with a non‐linear threshold to examine whether labour force participation rates are mean reverting for G7 countries using annual data over a 130 year period. We find some evidence of mean reversion for just over half the sample; however, this result is sensitive to regime shifts. We also examine whether the labour force participation rate is trend reverting through employing a lagrange multiplier (LM) unit root test with one and two structural breaks in the intercept and slope. The LM unit root test provides no additional evidence in support of stationarity. On the basis of the unit root tests for mean reversion we conclude that there is at best mixed evidence that long‐term changes in unemployment rates translate into long‐term changes in employment rates and that the unemployment rate is a useful indicator of joblessness.     

DO INVESTMENT‐SPECIFIC TECHNOLOGICAL CHANGES MATTER FOR BUSINESS FLUCTUATIONS? EVIDENCE FROM JAPAN

The observed decline in the relative price of investment goods to consumption goods in Japan suggests the existence of investment‐specific technological (IST) changes. We examine whether IST changes are a major source of business fluctuations in Japan, by estimating a dynamic stochastic general equilibrium model using Bayesian methods. We show that IST changes are less important than neutral technological changes in explaining output fluctuations. We also demonstrate that investment fluctuations are mainly driven by shocks to investment adjustment costs. Such shocks represent variations of costs involved in changing investment spending, such as financial intermediation costs. We find that the estimated series of the investment adjustment cost shock correlates strongly with the diffusion index of firms' financial position in the Tankan (Short‐term Economic Survey of Enterprises in Japan). Therefore, we argue that the large decline in investment growth in the early 1990s was due to an increase in investment adjustment costs stemming from firms' financial constraints after the collapse of Japan's asset price bubble.     

DOES MARKET‐ORIENTED ECONOMIC TRANSITION ENHANCE ENTERPRISE PRODUCTIVITY? EVIDENCE FROM CHINA'S ENTERPRISES

Using a panel of China's enterprises from 1999 to 2007, this paper examined how market‐oriented economic transition affects the productivity of China's enterprises given the various stages of enterprises in the commercialization process and given the market segmentation among Chinese different regions. The main findings are that: (i) enterprises with higher degrees of commercialization have relatively higher productivity, whereas enterprises with higher degrees of market segmentation have relatively lower productivity; (ii) the commercialization process and market segmentation act indirectly affect productivity through enterprises' capacity to export, innovate and obtain business loans; and (iii) the indirect effects are found to be significantly different between the commercialization process and market segmentation, highlighting the effects of the market‐oriented economic transition on enterprises' productivity. This paper provides reliable enterprise‐level evidence regarding the sources and evolution of enterprise productivity during different stages of market‐oriented economic transition in China.     

IS MARKET‐ORIENTED REFORM PRODUCING A ‘TWO‐TRACK’ EUROPE? EVIDENCE FROM ELECTRICITY AND TELECOMMUNICATIONS

ABSTRACT: The European Commission has formally recognized that adequate provision of basic household services, including energy, communications, water and transport, is key to ensuring equity, social cohesion and solidarity. Yet little research has been done on the impact of the reform of these services in this regard. This article offers an innovative way to explore such questions by analyzing and contrasting stated and revealed preferences on citizen satisfaction with and expenditure on two services, telecommunications and electricity, in two large countries, Spain and the UK. We find evidence that in telecommunications, but not in electricity, reform has led to a ‘two‐track’ Europe, where citizens who are elderly, not working or the less‐educated behave differently in the market, with the result that they are less satisfied with these services than their younger, working, better‐educated, counterparts.     

MORE COSTLY OR MORE PRODUCTIVE? MEASURING CHANGES IN COMPETITIVENESS IN MANUFACTURING ACROSS REGIONS IN CHINA

Using a newly constructed industry-by-region dataset based on China's two censuses, this paper examines the trend of average labor compensation (ALC), labor productivity (ALP) and unit labor cost (ULC) in 28 manufacturing industries across 29 provinces in China for 1995 and 2004. Findings show that at the aggregate level, ALP growth was generally faster than that of ALC and hence resulted in a significant decline in ULC for all regions in China. Furthermore, less developed regions exhibited stronger productivity growth relative to labor cost increase than more developed regions, thus leading to a convergence in ULC levels across provinces and regions over this period. Comparing individual industries, we observe a substantial variation in growth rates and convergence trends across regions. Logit regression analysis confirms that labor-intensive industries are more likely to converge in ALP, ALC and ULC, whereas capital/skill-intensive industries tended to diverge. This finding is further confirmed by estimating a convergence regression, which suggests that misallocation of resources due to market imperfections or institutional barriers is likely to be the main factor behind the divergence of ULC.     

HOW IMPORTANT ARE TERMS‐OF‐TRADE SHOCKS?

According to conventional wisdom, terms‐of‐trade shocks represent a major source of business cycles in emerging and poor countries. This view is largely based on the analysis of calibrated business‐cycle models. We argue that the view that emerges from empirical structural vector autoregression (SVAR) models is strikingly different. We estimate country‐specific SVARs using data from 38 countries and find that terms‐of‐trade shocks explain less than 10% of movements in aggregate activity. We then estimate key structural parameters of a three‐sector business‐cycle model country by country and find a disconnect between the importance assigned to terms‐of‐trade shocks by theoretical and SVAR models.     

SHORT‐RUN POLICY COMMITMENT WHEN INVESTMENT TIMING IS ENDOGENOUS: ‘MORE HARM THAN GOOD?’

In our model, firms choose when to set cost‐reducing investment and the government, which only has short‐run commitment power, sets an output subsidy. We show that firms that delay investment without government intervention have an incentive to invest early under policy activism, strategically underinvesting or overinvesting to obtain larger subsidies. The policy scheme thus creates a new, potentially more harmful, distortion. Under oligopoly, a firm has a weaker incentive to manipulate policy than under monopoly, which makes policy intervention less harmful. We investigate when the government may do better by adhering to laissez‐faire than by engaging in active policy intervention.     

HOW DO POLICY‐MAKERS ACTUALLY SOLVE PROBLEMS? EVIDENCE FROM THE FRENCH LOCAL PUBLIC SECTOR

This article examines how policy-makers solve problems within local representative democracies. It will be argued that politicians cannot undertake an exhaustive search of all possible policy choices; instead, they might use an incremental strategy such as the hill-climbing heuristic. These possibilities will be formalized using the median voter model as an analytical framework. The corresponding models will then be estimated over a set of French jurisdictions (the départements ). The empirical results lend support to the hill-climbing model , given that: (1) for social welfare and secondary school expenditures, the influence of the past is significant; (2) a pure model of incrementalism, without any exogenous variables, is not appropriate for explaining the behavior of departmental council members; and (3) the impact of the past is more significant and stronger when expenditure levels are higher.     

HOW COOPERATIVE ARE SAVINGS AND CREDIT COOPERATIVES IN DEVELOPING COUNTRIES?: AN ANALYSIS OF DATASETS FROM UGANDA

Building successful savings and credit cooperatives (SACCOs) that actually embody the cooperative principles is a challenge to development agencies. Although SACCOs form the majority of microfinance providers in many developing countries, the most recent literature on microfinance governance and performance has given little reference to the longstanding body of relevant cooperative literature. SACCO representation in microfinance datasets is biased. Drawing on so‐far unexploited datasets of Ugandan SACCOs and savings groups, this paper empirically analyses policy debate regarding SACCO‐ and savings group regulation. The findings point to the relevance of practically implementing the principle of ‘cooperation between cooperatives’ to ensure effective governance at SACCO level. Moreover, the paper introduces two new measures, based on members' savings and shares, which could become useful tools to track the application of cooperative principles in developing countries, and hence improve evidence‐based policy‐making for SACCOs.     

ARE WAGE INCREASES IN CHINESE STATE INDUSTRY EFFICIENT? PRODUCTIVITY IN NANJING'S MACHINE-BUILDING INDUSTRY

Since China's economic reform began, wages in state enterprises have increased at rates much faster than the rate of price inflation. This paper investigates the source of this rapid wage increase for a sample of Chinese state-owned machine-building enterprises to determine whether increased wages can be best explained by changes in productivity, changes in the output market, or changes in input markets. CES production function estimates find the marginal product of labor was stagnant between 1980 and 1992 but initially higher than wages. Rising wages were therefore consistent with other evidence that the reform process cost the state sector its labor monopsony. ( JEL P31)
