Inefficiency and heterogeneity in Turkish banking: 1990–2000

Recent studies have stressed the importance of privatization and openness to foreign competition for bank efficiency and economic growth. We study bank efficiency in Turkey, an emerging economy with great heterogeneity in bank types and ownership structures. Earlier studies of Turkish banking had three limitations: (i) excessive reliance on cost‐function frontier analyses, wherein volume of loans is a measure of banking output; (ii) pooling all banks or imposing ad hoc heterogeneity assumptions; and (iii) lack of a comprehensive panel data set for proper analysis of productivity and heterogeneity. We use an estimation–classification procedure to find likelihood‐driven classification of bank technologies in an 11‐year panel. In addition, we augment traditional cost‐frontier analysis with a labour‐efficiency analysis. We conclude that state banks are not particularly inefficient overall, but that they do utilize labour inefficiently. This partially supports recent calls for privatization. We also conclude that special finance houses (or Islamic banks) utilize the same technology as conventional domestic banks, and do so relatively efficiently. This suggests that they do not cause harm to the financial system. Finally, we conclude that foreign banks utilize a different technology from domestic ones. This suggests that one should not overstate their value to the financial sector. Copyright © 2005 John Wiley & Sons, Ltd.     

Does recession drive convergence in firms’ productivity? Evidence from Spanish manufacturing firms

This paper provides evidence on the effect of recessions and expansions on the productivity growth rate of productivity leaders and followers. We use data of a representative sample of the Spanish manufacturing sector for the period 1991 and 2005. These data allow us to estimate firm level productivity for a relatively long period of time and provide us with firm level perception of the business cycle. We find that productivity tends to converge in recessions because, in these periods, the productivity growth of followers is higher than the productivity growth of leaders. This fact is consistent with theoretical models of managerial incentives and competition. A recession can be seen as an exogenous increase in competition that reduces demand and poses a threat of liquidation. This threat is higher for followers and is high enough to create asymmetric incentives to become more productive. We test the robustness of our results to sample selection and different productivity measure.     

Product Market Competition,Skill Shortages and Productivity: Evidence from Canadian Manufacturing Firms

In this paper, we estimate the impacts of product market competition and skill shortages on the productivity level performance of Canadian manufacturing firms. We use firms perceptions of their competitive environment from the Statistics Canada 1999 Survey of Innovation to measure product market competition and skill shortages. We argue in the paper that such perceptions are important for productivity level performance. After controlling for other factors, we find that product market competition has a positive impact on the performance of medium-sized and large-sized firms, and that skill shortages have a negative impact on the performance of small-sized and medium-sized firms.Jel Classification: L0, O0     

Profit, productivity and distribution: Differences across organizational forms - The case of Spanish banks

We examine variations in financial and economic performance as a function of organizational form, and, over time. The forms we consider include Spanish commercial banks, savings banks, and financial cooperatives. We decompose multilateral variation in operating profit, our measure of financial performance, into price and quantity effects. We then decompose the latter into a margin effect and productivity change. Our measure of economic performance, productivity variation, is subsequently disaggregated into technical, cost efficiency, and scale. We find that deregulation and liberalization have acted to narrow performance gaps among organizational forms; this, despite less-than compelling evidence that increased competition has contributed to this convergence. For the Spanish banking system as a whole, the margin effect appears to deliver twice as much financial benefit as do improvements in productivity. Importantly, this finding does not vary across organizational form. Such regularity has an important implication: Incentives for growth are apparently provided by a positive margin rather than by the more elusive benefits of economies of scale and improved cost efficiency.     

Determinants of the method of payment in mergers and acquisitions

We empirically investigate the determinants of the payment form in mergers and acquisitions and introduce new variables on the target and acquirer investment characteristics to evaluate whether the concerns of target and acquirer shareholders are taken into account. Our sample encompasses mergers between publicly listed US companies from 1985 to 2004. Similarly we also consider the determinants of announcement returns using the same set of variables. We establish the relevance of a previously unreported variable for the determination of the payment form, the correlation of returns between target and acquirer, besides the more established determinants hostile takeovers, and defence mechanisms; weak evidence is found for the significance of budget constraints and no evidence for asymmetric information or tax considerations being a relevant factor. We do not find that announcement returns are explained by the variables considered.     

Inferring welfare maximizing treatment assignment under budget constraints

This paper concerns the problem of allocating a binary treatment among a target population based on observed covariates. The goal is to (i) maximize the mean social welfare arising from an eventual outcome distribution, when a budget constraint limits what fraction of the population can be treated and (ii) to infer the dual value, i.e. the minimum resources needed to attain a specific level of mean welfare via efficient treatment assignment. We consider a treatment allocation procedure based on sample data from randomized treatment assignment and derive asymptotic frequentist confidence interval for the welfare generated from it. We propose choosing the conditioning covariates through cross-validation. The methodology is applied to the efficient provision of anti-malaria bed net subsidies, using data from a randomized experiment conducted in Western Kenya. We find that subsidy allocation based on wealth, presence of children and possession of bank account can lead to a rise in subsidy use by about 9% points compared to allocation based on wealth only, and by 17% points compared to a purely random allocation.     

Demutualization,outsider ownership,and stock exchange performance: empirical evidence

We employ a balanced panel data set of 28 stock exchanges to disentangle the effects of demutualization and outsider ownership on the operative performance of stock exchanges. For this purpose we calculate in a first step individual efficiency and factor productivity values via Data Envelopment Analysis. In a second step we regress the derived values on variables that—amongst others—represent the different governance regimes of exchanges in order to examine technical efficiency and factor productivity differences between (1) mutuals, (2) demutualized but customer-owned exchanges, and (3) publicly listed and thus at least partly outsider-owned exchanges. We find evidence that demutualized exchanges exhibit higher technical efficiency than mutuals. However, they perform relatively poor as far as productivity growth is concerned. Furthermore, we find no evidence that publicly listed exchanges possess higher efficiency and productivity values than demutualized exchanges with a customer-dominated structure.      

The Role of Symmetry between the Revenue and the Expenditure Side of the Government Budget in the Debate about the Potential Negative Effects of Tax Competition

The effects of capital tax competition are reconsidered in this paper incorporating the argument that the expenditure structure of public budget should reflect its revenue structure. The paper offers a small open economy model where capital and labour tax revenues are used exclusively on the provision of public inputs. It is shown that if the revenue side of the government budget exactly matches the expenditure side that is if industrial public goods are financed by both private production factors with the weights reflecting the contributions of public inputs to the private factor productivity then public inputs are provided optimally even in the presence of tax competition.     

Environmental regulations in private and mixed duopolies: Taxes on emissions versus green R&D subsidies

In this article, we compare two kinds of environmental regulations—emissions taxes and green R&D subsidies—in private and mixed-duopoly markets in the presence of R&D spillovers. We show that a green R&D subsidy is better (worse) than an emissions tax when the green R&D is efficient (inefficient), irrespective of R&D spillovers, whereas the existence of a publicly owned firm encourages the government to adopt a subsidy policy. We also show that the optimal policy choice depends on R&D efficiency and spillovers. In particular, when green R&D is inefficient and the spillover rate is low (high), the government should choose an emissions tax and (not) privatize the state-owned firm. When green R&D is efficient, however, an R&D subsidy is better, but a privatization policy is not desirable for society, irrespective of spillovers.

Productivity Shocks and Labour Market Outcomes for Top Earners: Evidence from Italian Serie A

How are top earners affected by productivity shocks? We address this question using a unique longitudinal data set on the universe of professional football players in the Italian Serie A, representing 20% of top earners in Italy. We use traumatic injuries and adopt an IV strategy to provide causal estimates of the impact of productivity shocks on several labour market outcomes. We find that a 30-day injury substantially affects the probability of contract renegotiation and reduces net wages by around 12%. We show that this large penalty is due to employer's precautionary motives rather than to shock-induced reduction in current player's performance.     

Incentive Effects in Higher Education: an Improved Funding Model for Universities

We examine the incentive effects of risk‐sharing between student and university in the English higher education system. The ‘graduate premium’ has been widely reported and has been used to justify rising higher education participation and increased individual or governmental expenditure. But this premium is simply the mean of a wide distribution, varying, inter alia, by subject, institution, year of graduation and individual. We assume that universities exist in a state of monopolistic competition and are subject to a budget constraint. Using US college data we find evidence suggesting that a funding model which incorporates risk‐sharing improves the efficiency of educational delivery while maintaining subject diversity and access.     

New techniques in the measurement of multifactor productivity

This article outlines procedures for adjustment for characteristics of the production structure which are typically ignored in productivity growth computations but affect the correct valuation of inputs and outputs. There are many such characteristics, including changes in the terms of trade and fixity of factors, but only one appears to have much impact on productivity fluctuations: imperfect competition in output and input markets. To illustrate this, traditional and adjusted productivity growth indexes based on assumed markups are constructed for the U.S., Canadian and Japanese business sectors for comparison with each other and with other adjustments done in previous studies. The methodology is based on finding shadow values of all domestic and traded outputs and inputs to use to evaluate the contribution of each to profits. We find that evidence of markups suggests adjustments in traditional measures that are quite significant and which tend to smooth both cyclical and time trends in productivity growth.The refereeing process of this paper was handled through M.

The Relative Price of Non‐traded Goods under Imperfect Competition*

We consider the role of imperfect competition in explaining the relative price of non‐traded to traded goods within the Balassa–Samuelson framework. Under imperfect competition in these two sectors, relative prices depend on both productivity and mark‐up differentials. We test this hypothesis using a panel of sectors for 12 OECD countries. The empirical evidence suggests that relative price movements are well explained by productivity and mark‐up differentials.     

Soft budget constraints and strategic interactions in subnational borrowing: Evidence from the German States, 1975-2005

Cooperative federations are usually characterized by the existence of bailout guarantees and intergovernmental transfer schemes. This paper explores whether such features of cooperative federations lead to subnational soft budget constraints using panel data from the German States covering the 1975-2005 period. The methodology is based on the premise that subnational governments’ borrowing will exhibit vertical and horizontal strategic interactions if they operate under soft budget constraints. Therefore, a test for strategic interactions in subnational borrowing can be used to infer whether a cooperative federation like Germany is susceptible to soft budget constraints. The results suggest that state borrowing in Germany exhibited horizontal but not vertical interactions during the time-frame of the analysis. This indicates (i) that German States faced soft budget constraints and (ii) that they were more concerned about the likelihood of a bailout than about its volume.     

Industry influence on firms' R&D and innovation

This paper examines the effect of peers on a firm's research and development (R&D) policy. We show that firms do not make R&D decisions in isolation, and that industry dynamics play an important role in defining a firm's R&D intensity. Using a large sample of 54,393 firm-year observations from 1991 to 2015 in the United States, we find that firms' R&D decisions are mainly driven by their industry peers' R&D policies. Moreover, we find that R&D mimicking is significant only in the presence of strong product market competition, whereas we do not find any evidence of information-based herding in R&D investments. Our additional analysis shows that our main conclusions remain valid even in the presence of financial constraints, and regardless of the firms' market positions. Finally, we provide evidence that R&D mimicking increases firms' future values, future patent outputs, and estimated patent dollar values. Our findings are robust to endogeneity concerns, and to using alternative sample compositions, R&D intensity proxies, and different industry classifications.     

Entry, reforms, complementarity and performance: A tale of two Indian manufacturing sectors

In this paper, we use plant-level data from two Indian industries, namely, electrical machinery and textiles, to examine the empirical relationship between structural reforms like abandonment of entry restrictions to the product market, competition and firm-level productivity and efficiency. These industries have faced different sets of policies since Independence but both were restricted in the adoption of technology and in the development of optimal scales of production. They also belonged to the first set of industries that benefited from the liberalization process started in the 1980s. Our results suggest that both the industries have improved their efficiency and scales of operation by the turn of the century. However, the process of adjustment seems to have been worked out more fully for electrical machinery. We also find evidence of spatial fragmentation of the market as late as 2000–2001. Gains in labour productivity were much more evident in states that either have a strong history of industrial activity or those that have experienced significant improvements in business environment since 1991.     

EPA enforcement,firm response strategies,and stockholder wealth: an empirical examination

We investigate the effect of EPA pollution control enforcement activities and firm response strategies on stockholders' wealth. We find that the market reacts negatively upon learning that the firm has been targeted, and that losing a contest with the EPA is very costly to stockholders. Apparently firms are not expected to recover a significant part of pollution control costs from their customers. Somewhat surprisingly, losses are only weakly related to the presence of (unregulated) foreign competition, suggesting that untargeted domestic competitors may restrain cost recovery. Our analysis also indicates that firms may benefit by cooperating with the EPA; i.e., compliant strategies reduce (but don't avoid) wealth losses. The losses of firms that settle are about 40% less than those of firms that fight and lose, and we find no evidence of value gains for firms that fight and win. © 1998 John Wiley & Sons, Ltd.

The causal relation between government revenue and spending: Evidence from Egypt and Jordan

In investigating the causal relation between government revenue and spending, our empirical results support the tax-and-spend hypothesis for Egypt and the fiscal synchronization hypothesis for Jordan. Breaking away from these historical trends is essential for both countries to eliminate the budget deficit and therefore ensure the availability of domestic saving for private investment. To cope with unemployment and poverty, continuing privatization is recommended for both countries to improve productivity and efficiency in the domestic economy. Privatization should lead to higher domestic saving and investment and at the same time eliminate the budget deficit by enhancing revenue and curbing spending. (JEL H62, H63)
