growth and profitability of small and medium sized enterprises some welsh evidence foreman peck j makepeace g and morgan b 2006 growth and profitability of small and medium sized enterprises some welsh evidence regional studies 40 307 319 policy makers throughout the organization for economic co operation and development oecd are keen to promote the development of small and medium sized enterprises smes by a wide variety of means the present study of over 1600 welsh smes casts doubt on the effectiveness of doing so by grants by encouraging trade associations by pursuing current initiatives in training or by stimulating innovation as defined by sme management on the other hand it finds that support for selective information technology investment and for marketing planning could be beneficial additional results that might be addressed by policy are short termism by older managers preferring current to future profits more than younger managers signs that fixed costs of tax compliance bear substantially more heavily on the profitability of smaller smes and evidence

two dimensional efficiency decomposition to measure the demand effect in productivity analysis this paper proposes a two dimensional efficiency decomposition 2ded of profitability for a production system to account for the demand effect observed in productivity analysis the first dimension identifies four components of efficiency capacity design demand generation operations and demand consumption using network data envelopment analysis network dea the second dimension decomposes the efficiency measures and integrates them into a profitability efficiency framework thus each component s profitability change can be analyzed based on technical efficiency change scale efficiency change and allocative efficiency change an empirical study based on data from 2006 to 2008 for the us airline industry finds that the regress of productivity is mainly caused by a demand fluctuation in 2007 2008 rather than technical regression in production capabilities

did migration in the 1980s narrow the north south divide this paper integrates empirical analysis of the decision to migrate from a region with that of destination choice thus we are able to study how net migration and not just gross outflows are influenced by regional labour market circumstances the results suggest that relative regional wages rates but not relative unemployment and vacancy rates are effective in reallocating labour from regions experiencing adverse demand shocks we find little evidence that manual labour is migrating from those regions with relatively high manual unemployment but that migration plays a more conventional role in the regional adjustment process for non manual workers

explicit versus implicit contracts for dividing the benefits of cooperation abstract experimental evidence has accumulated highlighting the limitations of formal and explicit contracts in certain situations and has identified environments in which informal and implicit contracts are more efficient this paper documents the superior performance of explicit over implicit contracts in a new partnership environment in which both contracting parties must incur effort to generate a joint surplus and one strong agent controls the surplus division in the treatment in which the strong agent makes a non binding cheap talk bonus offer to the weak agent this unenforceable promise doubles the rate of joint high effort compared to a baseline with no promise the strong agents most frequently offered to split the gains of the high effort equally but actually delivered this amount only about one quarter of the time an explicit and enforceable contract offer performs substantially better increasing the frequency of the most efficient outcome by over 200 relative to the baseline

an experimental study of incentive contracts for short and long term employees abstract motivated by real world observations of different contract offers we conduct a lab experiment to examine a principal s contract choice and agent effort in both long and short term employment relationships implemented as one shot and repeated games we find that a piece rate contract has the strongest incentive effect on short term agents effort and is the principals dominant choice nevertheless the bonus contract works almost as well as the piece rate contract for long term relationships but not so well for short term relationships in addition the bonus contract s effect on effort is mainly driven by the bonus component suggesting that a fixed wage alone is not an effective mechanism to improve workers performance

manual wage differentials collective bargaining and multi locational firms an analysis using northern ireland nes data harris r 1994 manual wage differentials collective bargaining and multilocational firms an analysis using northern ireland nes data reg studies 28 483 493 a number of studies have appeared in the literature which consider the impact on the wage distribution of for example gender and ethnic differences of union membership or coverage by collective agreements of firm size of belonging to the private vis a vis public sector of being self employed as opposed to an employee another potentially important determinant of wages is whether the firm employing an individual is locally owned or whether it is part of a multiregional or multinational organization which operates branches in various locations this paper sets out to investigate the size of this locational wage differential across all sectors for a region of the uk using a bivariate sample selectivity model where the choice of firm type i e locally owned or externally owned and union coverage are endogenous the results confirm that

a regional general equilibrium model of the united states tax effects on factor movements and regional production a six region general equilibrium model of the united states is used to assess the potential long run effects of state local and federal tax policies on output and the allocation of factors across regions and sectors the nonuniform structure of state local taxes and their interaction with federal taxes means that regional output is affected quite differently than would be projected solely on the basis of changing average regional tax burdens the study provides a useful indication of conceptual and empirical issues that must be considered in further regional modeling efforts issues which do not arise in closed economy national models copyright 1989 by mit press

the red queen in action the longitudinal effects of capital investments in the mobile telecommunications sector organizations undertake capital investments in technology to generate revenues or decrease costs and thereby enhance profitability however red queen type responses by competing organizations in the form of rapid imitation and escalating of technology investments erode the ability of the investing organizations to sustain gains in profitability productivity gains from these investments may persist but they may not translate into sustained profitability gains owing to declining prices brought about by a hypercompetitive environment the emergence and erosion of benefits attributable to capital investments is examined by decomposing profitability into productivity price recovery product mix and capacity utilization and by regressing each performance measure on past technology investments a polynomial distributed lag model is estimated with quarterly data for 30 firms in the mobile telecommunications services sector from 1996 to 2005 the results indicate that capital investments are positively associated with productivity of current and future periods and their association with profitability is only positive in the future after six quarters these results highlight a unique outcome of the red queen hypothesis simply by imitating learning and investing in technology due to competition is beneficial to all firms in the industry

robustness and linear contracts abstract we consider a moral hazard problem where the principal is uncertain as to what the agent can and cannot do she knows some actions available to the agent but other unknown actions may also exist the principal demands robustness evaluating possible contracts by their worst case performance over unknown actions the agent might potentially take the model assumes risk neutrality and limited liability and no other functional form assumptions very generally the optimal contract is linear the model thus offers a new explanation for linear contracts in practice it also introduces a flexible modeling approach for moral hazard under nonquantifiable uncertainty jel d81 d82 d86

piece rates fixed wages and incentives evidence from a field experiment data from a field experiment are used to estimate the gain in productivity that is realized when workers are paid piece rates rather than fixed wages the experiment was conducted within a tree planting firm and provides daily observations on individual worker productivity under both compensation systems unrestricted statistical methods estimate the productivity gain to be 20 since planting conditions potentially affect incentives structural econometric methods are used to generalize the experimental results to out of sample conditions the structural results suggest that the average productivity gain outside of the experimental conditions would be at least 21 7

fairness incentives and contractual choices this paper examines how the presence of a non negligible fraction of reciprocally fair actors changes the provision of incentives through contracts we provide experimental evidence that principals have a strong preference for less complete contracts although the standard self interest model predicts that they should prefer the more complete contract our theoretical analysis shows that fairness concerns can explain this preference for less completeness fair principals keep their promises which provides strong pecuniary incentives through an incomplete contract selfish principals free ride and exploit the agents counter intuitively selfish agents are induced to work by an incomplete contract while fair agents shirk

relational incentive contracts standard incentive theory models provide a rich framework for studying informational problems but assume that contracts can be perfectly enforced this paper studies the design of self enforced relational contracts i show that optimal contracts often can take a simple stationary form but that self enforcement restricts promised compensation and affects incentive provision with hidden information it may be optimal for an agent to supply the same inefficient effort regardless of cost conditions with moral hazard optimal contracts involve just two levels of compensation this is true even if performance measures are subjective in which case optimal contracts terminate following poor performance jel c73 d82 l14

radial and non radial decompositions of profit change with an application to indian banking abstract grifell tatje and lovell grifell tatje e lovell c a k 1999 profits and productivity management science 45 1177 1193 made significant contributions to the literature on the extended radial dea framework by decomposing profit change into six mutually exclusive components their approach however poses two basic problems first the radial estimates on these components might give conflicting signals about the direction of profit change after the full radial efficiencies are achieved when slacks are present second evaluations of these components using base period prices as weights can be potentially misleading to address these concerns we first introduce non radial dea models and then provide a few strong theoretical arguments in favor of using as weights either current period prices or an average price covering both periods to value the contributions of each of these components the indian banking sector is taken as a case study to illustrate the radial and non radial decompositions of profit change so as to empirically examine the role of competition on profit change and its drivers our broad empirical results are as follows first radial and non radial models yield diametrically opposite results on the contributions of various components second the increasing efficiency change trends in all ownership groups after 2002 indicate that the government reform process instituted on the banking industry has had a favorable effect on the performance of the indian banking sector third despite the fact that nationalized banks are the oldest banks their output and resource allocation behaviors do not reflect their learning experience

inequality and convergence in europe s regions reconsidering european regional policies europe s regions income disparities and regional policies in this paper we take a critical look at current european regional policies first we document the motivation for such policies that is the large income disparities across the regions of the eu15 large disparities are certainly present second we illustrate the various instruments adopted and discuss their underpinnings in established economic theories next we look at available data searching for three kinds of evidence 1 if disparities are either growing or decreasing we conclude they are neither 2 which are the major factors explaining such disparities and in particular if they are the factors predicted by the economic models adopted by the commission to justify current policies we conclude this is most certainly not the case 3 if there are clear signs that eu policies as opposed to other social and economic factors are actually reducing such disparities we cannot find any clear sign of such desired impact our conclusion is that regional and structural policies serve mostly a redistributional purpose motivated by the nature of the political equilibria upon which the european union is built they have little relationship with fostering economic growth this casts a serious doubt on their social value and furthermore strongly questions extending such policies to future members of the european union a successful eu enlargement in our view calls for an immediate and drastic revision of regional economic policies michele boldrin and fabio canova

profit productivity and price differential an international performance comparison of the natural gas transportation industry the objective of this paper is to evaluate the performance of natural gas transportation utilities focusing on the three key strategic performance measures of profit productivity and price differential we propose a methodology that expresses the three performance measures in a unified single equation using the edgeworth index the proposed methodology is applied to an international comparison of the performance of 28 natural gas transportation utilities operating in eight countries in which the business environments differ greatly the empirical results show the possible causes of performance differences and may shed some light on the direction of regulatory policy especially for developing countries that have relatively short histories in the natural gas industry such as korea

salaries and piece rates compensation can take many forms remuneration can come as pecuniary payments as fringes such as health and pension benefits or as a nonpecuniary reward such as plush office furniture that costs the firm less than it benefits the worker a significant literature has examined the trade offs between pecuniary and nonpecuniary compensation the modern work having been pioneered by rosen 1974 more recently another body of literature has examined the selection of method of total compensation ignoring the distinction between pecuniary and nonpecuniary payment this work has focused on risk and incentive factors it has resulted in comparisons of compensation based on absolute output levels to that based on relative performance it has also led to explorations of the relation of compensation to experience over the work life 2 little attention has been paid to what may be among the most important and obvious distinction in methods of compensation namely the choice between a fixed salary for some period of time that is paying on the basis of input and some workers receive compensation that is specified in advance and not directly contingent on performance instead it depends on an input measure such as hours worked for others compensation is directly related to output this essay is an attempt to predict a firm s choice of compensation method piece rates are defined more rigorously among the more important factors discussed are worker heterogeneity incentives sorting considerations monitoring costs and asymmetric information one result is that salary workers tend to be of lower quality and more homogeneous than are their piece rate counterparts numerous additional results are provided helpful comments by victoria lazear and yoram weiss are gratefully acknowledged support was provided by the department of labor and the national science foundation 1 see lazear and rosen 1981 stiglitz 1981 holmstrom 1982 green and stokey 1983 2 see lazear 1979 1981 and harris and holmstrom in press

interdependencies between transport fuel demand efficiency and quality an application to austria abstract this paper focuses on the interdependencies between technical efficiencies and energy demand which are often either treated in isolation or do not get the sufficient attention in the literature more precisely this paper uses technical efficiencies as one crucial determinant of energy demand in order to integrate at least two issues that are usually investigated separately from each other the rebound effect resulting from improved technical efficiencies and the asymmetry of energy demand in this regard our paper sets out a theoretical framework which has the following implications higher efficiency increases service demand first order rebound low fuel prices and higher efficiency increases the demand for quality second order which in turn increases service demand further third order ceteris paribus energy price shocks should increase scrapping rates fuel prices direct the rd those on engine efficiency are irreversible which has the consequence that energy price elasticities depend on the history of energy prices rather than being asymmetrical derived implications are subsequently tested on austrian data in particular the purchasing decision diesel versus gasoline powered cars allows to refute the myth that consumers apply high implicit rates for discounting the future benefit from efficient cars

a framework for analyzing changes in strategic performance in this paper we present a framework for analyzing changes in strategic performance traditional measures for comparing the strategic performance across firms or over time have been return on investment roi and its component ratio return on sales ros we decompose the ros ratio into four separate ratios that capture the impact of changes in a firm s productivity price recovery product mix and capacity utilization on its profitability these ratios help to highlight the micro sources of strategic success or failure they can be used to assess changes in the performance of a firm compared to itself over time or to other firms in its industry group this framework can also be used to evaluate changes in the dynamic performance of an industry as a whole we illustrate the use of these ratios with a 4 year analysis of the performance of a large manufacturing company we also demonstrate how the technique can be applied to an industry with an evaluation of the performance of u s telecommunications firms between 1975 and 1987 a period during which the industry experienced a progressive increase in competitive pressure

regional effects of taxes in canada an applied general equilibrium approach this paper reports on an applied general equilibrium regional model for canada which is used to investigate the regional effects of taxes earlier literature on regional tax effects is reviewed and the main features of the model are briefly described existing literature on regional tax effects is largely non quantitative and does not discuss several important regional features of taxes such as taxes which are predominantly on products or industries located in particular regions results suggest that regional effects of taxes can be significant and in the canadian case at least do not tend to counterbalance one another in general richer regions tend to lose and poorer regions gain from federal taxes but other regional characteristics such as manufacturing non manufacturing or resource non resource can be important this abstract was borrowed from another version of this item

distributive politics and regional development assessing the territorial distribution of turkey s public investment turkey is often perceived as a country with low bureaucratic capacity and prone to political manipulation and pork barrel this article tests whether this is the case by analysing the extent to which politics rather than equity and efficiency criteria have determined the geographical allocation of public investment across the 81 provinces of turkey between 2005 and 2012 the results show that although the turkish government has indeed channelled public expenditures to reward its core constituencies socioeconomic factors remained the most relevant predictors of investment moreover in contrast to official regional development policy principles we uncover the concentration of public investment in areas with comparatively higher levels of development we interpret this as the state bureaucracy s intentional strategy of focussing on efficiency by concentrating resources on the better off among the most in need

the growth of temporary services work the temporary help services industry which provides client firms with workers on an as needed basis has expanded at a phenomenal rate over the last 20 years since 1972 the industry s employment has grown at an annual rate of over 11 percent and its share of total u s employment has risen from under 0 3 percent in 1972 to more than 1 8 percent in 1995 the growth of the temporary services industry has fueled controversy some analysts fear that temporary workers may become locked into a labor market underclass with low wages no benefits negligible job security little training and no possibility for advancement others challenge such claims and point to efficiencies created by temporary employment relationships this article will examine the growth of the temporary services industry and discuss the quality of temporary services jobs how such jobs fit into workers careers and some of the forces that may be driving the growth of temporary services work

aggregation and linearity in the provision of intertemporal incentives we consider the problem of providing incentives over time for an agent with constant absolute risk aversion the optimal compensation scheme is found to be a linear function of a vector of n accounts which count the number of times that each of the n kinds of observable events occurs the number n is independent of the number of time periods so the accounts may entail substantial aggregation in a continuous time version of the problem the agent controls the drift rate of a vector of accounts that is subject to frequent small random fluctuations the solution is as if the problem were the static one in which the agent controls only the mean of a multivariate normal distribution and the principal is constrained to use a linear compensation rule if the principal can observe only coarser linear aggregates such as revenues costs or profits the optimal compensation scheme is then a linear function of those aggregates the combination of exponential utility normal distributions and linear compensation schemes makes computations and comparative statics easy to do as we illustrate we interpret our linearity results as deriving in part from the richness of the agent s strategy space which makes it possible for the agent to undermine and exploit complicated nonlinear functions of the accounting aggregates

nonlinear pricing under inequity aversion abstract we consider a monopoly which practices nonlinear pricing where buyers may have inequity averse preferences each buyer has a valuation for the good drawn from a distribution the monopoly knows the distribution but not the realizations we introduce the possibility that any buyer can be inequity averse fair types or not neutral types in addition to different demand types fair types get a disutility from inequity captured through a utility function in the spirit of the one introduced by fehr and schmidt 1999 we characterize the optimal nonlinear pricing and show that the degree of suboptimality increases and the monopoly profit decreases as the degree of the inequity aversion increases we also show that some or all of the neutral types with low demand are strictly better off when there are inequity averse types in the environment

implicit contracts incentive compatibility and involuntary unemployment this paper considers the enforceability of employment contracts when employees performance cannot be verified in court so that piece rate contracts are not legally enforceable part i shows that there exists a variety of self enforcing implicit contracts modelled as perfect equilibria in a repeated game and characterizes all the wage and performance outcomes that can be implemented implementation requires a strictly positive surplus from employment the form of the contract depending on how this surplus is divided between firm and employee piece rate contracts and contracts with an informally agreed bonus can be made self enforcing but the use of severance pay and bonding does not extend the set of implementable allocations the resulting contracts resemble actual labor contracts more than do the contracts in standard principal agent models part ii analyses market equilibrium with these contracts also modelled as perfect equilibria in a repeated game and shows that many such equilibria exist unfilled vacancies and unemployed workers can co exist despite the existence of contracts that are potentially mutually beneficial for those jobs that are filled any division of the potential surplus is possible so that the market can have at the same time involuntary unemployment and vacancies that are unfilled despite filled jobs earning positive profits as a criterion for selecting equilibria a notion of renegotiation proofness is applied then either all workers are employed or all jobs filled but any division of the potential surplus is still possible the paper explores what further restrictions on beliefs give rise to a walrasian outcome in which all the potential surplus goes to the short side of the market and to an efficiency wage type outcome in which the potential surplus goes to the long side

performance in competitive environments gender differences even though the provision of equal opportunities for men and women has been a priority in many countries large gender differences prevail in competitive high ranking positions suggested explanations include discrimination and differences in preferences and human capital in this paper we present experimental evidence in support of an additional factor women may be less effective than men in competitive environments even if they are able to perform similarly in non competitive environments in a laboratory experiment we observe as we increase the competitiveness of the environment a significant increase in performance for men but not for women this results in a significant gender gap in performance in tournaments while there is no gap when participants are paid according to piece rate this effect is stronger when women have to compete against men than in single sex competitive environments this suggests that women may be able to perform in competitive environments per se

attention in games an experimental study abstract a common assumption in game theory is that players concentrate on one game at a time however in everyday life we play many games and make many decisions at the same time and have to decide how best to divide our limited attention across these settings in this paper we ask how players solve this attention allocation problem we find that players attention is attracted to particular features of the games they play and how much attention a subject gives to a given game depends on the other game that the person is simultaneously attending to
