competition and corporate performance are people right to think that competition improves corporate performance my investigations indicate first that there are some theoretical reasons for believing this hypothesis to be correct but they are not overwhelming furthermore the existing empirical evidence on this question is weak however the results reported here based on an analysis of around 670 u k companies do provide some support for this view most important i present evidence that competition as measured by increased numbers of competitors or by lower levels of rents is associated with a significantly higher rate of total factor productivity growth

market share market value and innovation in a panel of british manufacturing firms this paper examines the empirical relationship between technological innovations market share and stock market value new developments in the estimation of dynamic count data models are used to control for unobserved firm specific heterogeneity we find a robust and positive effect of market share on observable headcounts of innovations and patents although increased product market competition in the industry tends to stimulate innovative activity furthermore the impact of innovation on market value is larger for firms with higher market shares we argue that our results are consistent with models where high market share firms have incentives to pre emptively innovate

the strategic equivalence of rent seeking innovation and patent race games abstract we establish the strategic equivalence of a variety of rent seeking contests innovation tournaments and patent race games the results allow us to disentangle negative and positive externalities and to apply theorems and results intended for rent seeking games to other games and vice versa we conclude with several examples that highlight the practical utility of our results

a long commodity cycle model of the world economy over a century and a half making bricks with little straw abstract this paper explores the world business cycle using unfiltered data from 1870 and looks for a theory that could account for the long wave commodity cycle in the world economy we build a simple dsge model that includes a long time to build constraint in the commodity sector we find that this model can produce long cycles in output and commodity prices as introduced by kontradieff 1925 and schumpeter 1934 our findings show that these long business cycles are produced by the long gestation of commodity capacity which causes very large swings in commodity prices

demand for football and intramatch winning probability an essay on the glorious uncertainty of sports the aims of this study are i to identify the main determinants of the demand for french premiere division football matches using all matches played during the 1997 1998 season ii to estimate a team specific probability of success and iii to propose an updating process for the intramatch winning probability the methodology is tested empirically over an out of sample data set using matches of the 1998 1999 season the results show that football appears to be an inferior product affected by both socio economic and football variables and that the main football variables have only a tenuous explanatory power concerning the final outcome of a given match

stabilization policy and the costs of dollarization this paper compares the welfare costs of business cycles in a dollarized economy to those associated with several alternative monetary regimes belonging to three broad families interest rate feedback rules inflation targeting and money growth rate rules the analysis is conducted within an optimizing model of a small open economy with sticky prices the model is calibrated to the mexican economy and is driven by 3external shocks terms of trade world interest rate and import price inflation we show econometrically that these shocks explain more than 75 of the observed forecasting error variance of mexican output and the mexican real exchange rate at 4 to 16 quarter horizons the welfare comparisons suggest that dollarization is the least successful of the monetary policy rules considered agents are willing to give up more than 2 of their non stochastic steady state consumption to see a policy other than dollarization implemented

rational speculation and exchange rates abstract models of exchange rates have typically failed to produce results consistent with the key fact that real and nominal exchange rates move in ways not closely connected to current or past macroeconomic variables models that rely on the same shocks to drive fluctuations in macroeconomic variables and exchange rates typically imply counterfactually strong co movements between them we develop a model in which new information leads agents to change their rational beliefs about risk premia on foreign exchange markets these changes in risk premia work through asset markets to cause real and nominal exchange rates to change without corresponding changes in gdp productivity money supplies and other key macro variables

how do competitive pressures affect incentives to innovate when there is a market for inventions competition and intellectual property ip protections are complements in stimulating innovation when ip is appropriable a market for inventions forms and competitive pressures increase incentives to innovate competition among producers the demand side of the market for inventions and competition among inventors the supply side of the market for inventions create incentives to innovate when ip is not fully appropriable markets for inventions are limited and competitive pressures can decrease incentives to innovate firms vertically integrate r d and production and share technology to appropriate the returns to ip this implies that antitrust policy and ip protections are complements

evaluating an estimated new keynesian small open economy model abstract this paper estimates and tests a new keynesian small open economy model in the tradition of christiano et al 2005 nominal rigidities and the dynamic effects of a shock to monetary policy journal of political economy 113 1 1 45 and smets and wouters 2003 an estimated stochastic dynamic general equilibrium model of the euro area journal of the european economic association 1 5 1123 1175 using bayesian estimation techniques on swedish data to account for the switch to an inflation targeting regime in 1993 we allow for a discrete break in the central bank s instrument rule a key equation in the model the uncovered interest rate parity uip condition is well known to be rejected empirically therefore we explore the consequences of modifying the uip condition to allow for a negative correlation between the risk premium and the expected change in the nominal exchange rate the results show that the modification increases the persistence in the real exchange rate and that this model has an empirical advantage compared with the standard uip specification

the impact of the 1981 and 1994 1995 strikes on major league baseball attendance a time series analysis protracted labour disputes in professional team sports have become increasingly common in the past 30 years although each of the four major professional team sports in the usa have experienced episodes of labour strife major league baseball has the longest and most frequent experience with labour management conflict fans and the media claim with each incident permanent harm is done to baseball s standing as the national pastime the purpose of this paper is to ascertain whether such claims can be supported by the empirical evidence utilizing time series analysis aggregate attendance at professional baseball games is examined the evidence presented suggests that although the most protracted periods of labour discord had short term impacts on attendance there is no empirical evidence that these exogenous shocks had any long term effects

external shocks financial volatility and reserve requirements in an open economy abstract the performance of a simple countercyclical reserve requirement rule is studied in a dynamic stochastic model of a small open economy with financial frictions imperfect capital mobility a managed float regime and sterilized foreign exchange market intervention bank funding sources domestic and foreign are imperfect substitutes the model is calibrated and used to study the effects of a temporary drop in the world risk free interest rate consistent with stylized facts the shock triggers an expansion in domestic credit and activity asset price pressures and a real appreciation an optimal credit based reserve requirement rule based on minimizing a composite loss function helps to mitigate both macroeconomic and financial volatility with the latter defined both in terms of a narrow measure based on the credit to output ratio the ratio of capital flows to output and interest rate spreads and a broader measure that includes real asset prices as well greater reliance on sterilization implies a less aggressive optimal reserve requirements rule implying that the two instruments are partial substitutes

evaluating changes in league structure the reorganization of the scottish football league this article investigates the relationship between league structure and the demand for professional team sport using data from the scottish football league sfl 1971 to 1980 the sfl was restructured in 1975 and thus provides an excellent opportunity for the empirical analysis of the influence of league structure the general channels by which league structure affects demand are explored estimates are made of the impact on individual clubs by predicting what attendances would have been in the absence of the league reorganization finally the distribution of attendances across clubs is examined for evidence of the influence of league structure

the quality of innovation and the extent of the market abstract i present a comprehensive model of international trade in technology that considers both the demand for inventions and the supply of inventions on the demand side domestic and foreign firms make strategic technology adoption decisions on the supply side inventors compete to sell licenses for their technology to domestic and foreign firms countries benefit from international trade in technology because they obtain the best invention from a larger pool of inventions international trade in technology increases the extent of the market for inventions and thereby improves the quality of innovation technology trade lowers prices increases outputs and increases the volume of trade in differentiated products when traded products are not close substitutes international markets for technology generate gains from trade the results of the analysis are robust to the possibility of technology transfer either through expropriation or imitation protection of intellectual property rights preserves incentives for entry of inventors and improves the quality of innovation

r d appropriability opportunity and market structure new evidence on some schumpeterian hypotheses one of the largest bodies of literature in the field of industrial organization is devoted to the interpretation and testing of several hypotheses advanced by joseph schumpeter 1950 concerning innovation and industrial market structure one set of hypotheses focuses on the role of firm size as a determinant of r d spending and the rate of technological advance another set focuses on the effect of market concentration on r d and technological advance in this paper we reexamine the latter set of hypotheses at the industry level using new data on r d appropriability and technological opportunity collected by levin et al 1984 in a survey of r d executives in 130 industries

innovation and market structure an empirical evaluation of the bounds approach in the chemical industry this paper applies sutton s 1998 bounds approach to the chemical industry the approach predicts that i the lower bound of the ratio of the 1 firm concentration index to product concentration is bounded away from zero at high levels of product concentration only in high r d markets and ii the lower bound on market concentration is higher and increasing in product concentration in markets with higher r d intensities we test these two hypotheses and find that the data strongly support them a novel feature of our analysis is the use of plant level data in defining products and the classification of products into markets based on end use

the demand for rugby league evidence from causality tests during the last few years there has been an upsurge of interest in the determinants of the demand for professional team sports typically traditional demand estimation techniques are used to examine the determinants of attendance this paper attempts to show that the use of these techniques may be misleading existing studies implicitly or explicitly assume a direction of causality econometric estimation techniques are then applied to examine this direction of causality however no account is taken of possible spurious regression and time series properties of the data are not fully explored these omissions may have led to faulty policy recommendations in attempting to rectify traditional approaches this study will examine the time series properties of rugby league attendence and success prior to engaging in estimation

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

innovation strategies as a source of persistent innovation an important topic in the recent literature on firms innovation is the question of whether and to what extent firms which innovate once have a higher probability of innovating again in subsequent periods this phenomenon is called the persistence of innovation although the literature has established that innovation persistence is indeed important from an empirical point of view relatively little attention has been paid to identifying the reasons why this is the case in this article we contribute to the literature by proposing that differences in innovation strategies across firms are an important driving force behind innovation persistence we analyses this issue using a panel database constructed from r d and community innovation surveys in norway empirical measures of five innovation strategies are identified by means of an inductive method ad hoc supplier based market driven r d intensive and science based a dynamic random effects probit model is used to estimate whether and to what extent these innovation strategies are a source of persistent innovation the results support the idea that the differences in innovation strategies across firms are an important determinant of the firms probability to repeatedly innovate more concretely we found that firms pursuing the strategies market driven r d intensive and science based were more likely to be persistent innovators we also distinguish the effects of strategy differences on the persistence of product and process innovation in all firms and within high tech versus low tech firms

the demand for semi pro league football in malaysia 1989 91 a panel data approach this article arguments the literature on the demand for professional team sports by estimating a demand function for attendance at home matches in the malaysian semi pro football league mspfl between 1989 and 1991 a single equation demand attendance function based on a pooled cross section and time series panel data set of 399 games is estimated by ordinary least squares a fixed effects dummy variable covariance model and an error components model our findings confirm the importance of market size and championship prospects for the home team but not the visiting team as well as divisional status and star players the first match of the season and derby matches also increased attendance

innovation and market structure in the dynamics of the pharmaceutical industry and biotechnology towards a history friendly model this paper is a first attempt at modelling the long term dynamics of market structure and innovation in the pharmaceutical industry in a history friendly way the model examines the relationships between the nature of the search space demand the patterns of competition and industry evolution in the age of random screening and in the age of molecular biology and shows that concentration in the pharmaceutical industry is shaped by lack of cumulativeness in innovative activities and market fragmentation the model conforms to our appreciative understanding and responds to changes in parameters concerning demand costs economies of scale opportunity conditions and the relative advantages of new biotechnology firms nbfs vis a vis incumbents with the exception of cost increases the model is quite robust to these changes in its essential features it is quite difficult to raise substantially concentration and to have nbfs displacing incumbents

our fans in the north the demand for british rugby league this paper reports the results of estimating a single equation model of an attendance function for british rugby league over the seasons 1982 83 to 1990 91 the data are panel data covering virtually every team which played in the two division league over the nine year time period diagnostic tests indicate that the appropriate model is a semilog random effects model where the dependent variable is league attendance weighted by population the major results are as follows there are significant positive relationships between league attendance and various measures of team success although the direction of causality is moot team quality as proxied by the two divisions and the economic quality of team location as proxied by the unemployment rate but there is no discernible relationship between league attendance and either success in nonleague trophy competitions or measures of exceptional player quality

optimal monetary policy under commitment with a zero bound on nominal interest rates we determine optimal monetary policy under commitment in a forwardlooking new keynesian model when nominal interest rates are bounded below by zero the lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear a calibration to the u s economy suggests that policy should reduce nominal interest rates more aggressively than suggested by a model without lower bound rational agents anticipate the possibility of reaching the lower bound in the future and this amplifies the effects of adverse shocks well before the bound is reached while the empirical magnitude of u s mark up shocks seems too small to entail zero nominal interest rates shocks affecting the natural real interest rate plausibly lead to a binding lower bound under optimal policy however this occurs quite infrequently and does not imply positive average inflation rates in equilibrium interestingly the presence of binding real rate shocks alters the policy response to non binding markup shocks

technological exploration through licensing new insights from the licensee s point of view the market for technology plays a crucial role in firms technology strategy as a way to undertake search in the available technological space drawing on innovation search theory and the literatures on licensing and absorptive capacity ac we address the issue of the factors that affect how technologically distant from the existing technological portfolio in licensing firms are able to move when they in license externally developed technologies we posit that a long technological distance reflects the outcome of more exploratory search while a short distance reflects the outcome of exploitative search we conjecture two distinct dimensions of ac in terms of the firms stock of knowledge assimilation capacity and the degree to which firms have searched broadly in the past monitoring ability t o affect the distance of exploration from the existing technological portfolio furthermore we compare firms that explore through licensing and firms which do not explore through licensing but do so through search reflected in own patenting activities we propose that the effects of assimilation capacity and monitoring ability should be more pronounced for licensees combining data on 176 license agreements and related patent information and while using a control sample of non licensing firms we find with exceptions support for these ideas

the demand for football in the regions of england and wales dobson s m and goddard j a 1996 the demand for football in the regions of england and wales reg studies 30 443 453 this paper investigates the determinants of the demand for football in the regions of england and wales using annual time series data over a 37 year period we use a dynamic error correction model to identify economic and football specific factors which determine attendances in the short run and long run the short run influences on demand are performance admission price and goal scoring performance and the unemployment rate are identified as significant long run determinants of attendance although the relationship between attendance share and performance seems to exhibit a strong regional dimension we find only weak evidence of regional variation in the coefficients of the attendance model itself dobson s m et goddard j a 1996 la demande de football aux regions de l angleterre et des pays de galles reg studies 30 443 453 cet article examine les determinants de la de

the incentives for cost reduction in a differentiated industry abstract this paper investigates how the incentives for cost reduction in a differentiated industry depend upon the degree of product substitutability when goods are imperfect substitutes both cournot and bertrand competition result in underinvestment in the sense that a social planner would be willing to pay more for a given cost reduction than a profit maximizing firm overinvestment may occur when the goods are sufficiently close substitutes similarly cournot competition provides a stronger incentive to innovate than bertrand competition if the degree of substitutability is low and a weaker incentive if this degree is high

designing a simple loss function for central banks does a dual mandate make sense yes it makes a lot of sense this paper studies how to design simple loss functions for central banks as parsimonious approximations to social welfare we show both analytically and quantitatively that simple loss functions should feature a high weight on measures of economic activity sometimes even larger than the weight on inflation two main factors drive our result first stabilising economic activity also stabilises other welfare relevant variables second the estimated model features mitigated inflation distortions due to a low elasticity of substitution between monopolistic goods and a low interest rate sensitivity of demand the result holds up in the presence of measurement errors with large shocks that generate a trade o between stabilising inflation and resource utilisation and also when imposing a moderate degree of interest rate volatility

approximate bertrand equilibria in a replicated industry this paper considers the existence and properties of approximate bertrand equilibria in a replicated industry price setting firms produce a homogeneous product with weakly convex costs the main results are that a given e 0 an e equilibrium exists if the industry is large enough b if the e is small enough and the industry large enough any e equilibrium is approximately competitive these results depend on how contingent demand is specified

market structure and research intensity in high technological opportunity industries where the cost and uncertainty of r d are high and conditions favor speedy imitation by competitors concentration has a statistically significant and substantial positive impact on research intensity but its impact is clearly negative when r d cost and uncertainty are low and where high barriers to imitation exist a sample of 160 business unit observations for 1978 was drawn from the pims data base all the sample business units industries recently experienced major technological changes research intensity was measured by non government financed r d expenditures as a percentage of sales

comparing cournot and bertrand equilibria in a differentiated duopoly with product r d abstract this paper compares bertrand and cournot equilibria in a differentiated duopoly with substitute goods and product r d i find that r d expenditure prices and firms net profits are always higher under quantity competition than under price competition furthermore output consumer surplus and total welfare are higher in the bertrand equilibrium than in the cournot equilibrium if either r d spillovers are weak or products are sufficiently differentiated if r d spillovers are strong and products are not too differentiated then output consumer surplus and total welfare are lower in the bertrand case than in the cournot case thus a key finding of the paper is that there are circumstances where quantity competition can be more beneficial than price competition both for consumers and for firms

on the dynamic efficiency of bertrand and cournot equilibria abstract this paper compares bertrand and cournot equilibria in a differentiated duopoly with r d research and development competition it shows that cournot competition induces more r d effort than bertrand competition however the price is lower and output is larger in bertrand than in cournot competition furthermore the bertrand equilibrium is more efficient than the cournot equilibrium if either r d productivity is low or spillovers are weak or products are very different if r d productivity is high spillovers are strong and goods are close substitutes then the bertrand equilibrium islessefficient than the cournot equilibrium journal of economic literatureclassification number l13

entry barriers and economic welfare the relationship between economic welfare and the number of firms in a quasi cournot market is examined in the first place we presuppose the existence of a strong first best government that can enforce the marginal cost principle to the firms along with regulating the number of firms it is shown that there exist excessive number of firms at the free entry quasicournot equilibrium vis a vis the first best welfare maximizing number of firms the thrust of this result essentially survives even if we replace a utopian first best government by a secondbest government that leaves the firms to pursue their respective profit maximization freely and engages solely in regulating the number of firms it can be shown that the excess entry prevails again in this second best world recent studies in the theoretical industrial organization literature have uncovered several instances which cast serious doubt on the reasonableness of a widespread belief that increasing competition will increase welfare stiglitz 1981 p 184 it has been shown that there are cases which are not altogether unreasonable where social welfare will be increased by strengthening rather than weakening the protection of incumbent firms from the threat of potential entry this is in sharp contrast with the traditional belief 2 what is not known however is how robust these pathologies in fact are we intend to settle this problem by proving two excess entry theorems in the quasi cournot parametric conjectural variations homogeneous oligopoly model seade 1980a b in the first place we presuppose the existence of a strong first best government that could costlessly enforce the marginal cost pricing principle by firms in an oligopolistic market and regulate entry in pursuit of first best social welfare optimization it is shown that the number of firms at the free entry equilibrium exceeds the first best welfare optimizing number of firms the result has already been noted by von weizsacker 1980a b and others in terms of numerical examples our theorem 1 asserts that this phenomenon always holds true for the family of quasi cournot models at hand an implication of this result is that the existence of entry barriers which protect incumbent firms from potential competitors is not necessarily welfare decreasing in sharp contrast with the traditional belief a problem remains with theorem 1 however in that an omnipotent first best government does not exist in reality and the first best ideal is unrealizable in the actual economy therefore even if the intervention by a first best government with a view to restricting the number of firms within an industry may be welfare improving it does

on the efficiency of bertrand and cournot equilibria with product differentation in a differentiated products setting with n varieties it is shown under certain regularity conditions that if the demand structure is symmetric and bertrand and cournot equilibria are unique then prices and profits are larger and quantities smaller in cournot than in bertrand competition and as n grows both equilibria converge to the efficient outcome at a rate of at least 1n if bertrand reaction functions slope upwards and are continuous then even with an asymmetric demand structure given any cournot equilibrium price vector one can find a bertrand equilibrium with lower prices in particular if the bertrand equilibrium is unique then it has lower prices than any cournot equilibrium

preemptive patenting and the persistence of monopoly this article takes a different tack and inquires whether institutions such as the patent system create opportunities for firms with monopoly power to maintain their monopoly power the results apply to other situations such as brand identification spatial location and capacity expansion which share the characteristic that early or preemptive actions may lower the returns to potential competitors

overoptimism and the performance of entrepreneurial firms recent theoretical and empirical research on cognitive bias in decision making suggests that overoptimism critically influences entrepreneurs decisions to establish and sustain new ventures we investigate whether such cognitive bias influences entrepreneurial venture performance using data on commercialization efforts for university inventions in contrast to prior studies our results suggest that entrepreneurial overoptimism does not appear to be the determining factor in the decision to found a firm we do find that entrepreneurs continue unsuccessful development efforts for longer periods of time than do established firms which is consistent with entrepreneurial overoptimism in the development of technologies with uncertain market prospects this latter finding is also consistent with rationality based models of decision making behavior however we find that the economic returns associated with many of the technologies in our sample are realized after the start up has been acquired by an established firm suggesting that start ups may serve as a transitional organizational form in the market for technology commercialization

impact of league restructuring on team sport attendances the case of rugby league an econometric analysis of attendances at rugby footbal league matches in england over the period 1966 1990 is presented the major finding is that the move from one to two leagues in 1973 had a substantial impact on attendances teams in the upper league experienced greater attendances ceteris paribuswhilst those in the lower league had reduced attendances

welfare reducing licensing abstract in this paper we characterize situations where licensing a cost reducing innovation to a rival firm using two part tariff contracts a fixed fee plus a linear per unit of output royalty reduces social welfare we show that it occurs if i the firms compete in prices ii the innovation is large enough but not drastic and iii the goods are close enough substitutes moreover we show that regardless of the type of competition first the optimal contract always includes a positive royalty and second even drastic innovations are licensed whenever the goods are not homogeneous

on licensing policies in bertrand competition abstract three licensing policies the auction the fee and the royalty are studied in a bertrand type duopoly with differentiated goods the analysis is conducted in terms of a multistage noncooperative game involving an external patentee and two firms each producing a differentiated good in bertrand price competition a principal finding is that for a patentee the royalty may be superior to the other two policies journal of economic literature classification numbers 026 611 621

how to license intangible property we examine the optimal licensing strategy of a research lab selling to firms who are product market competitors we consider an independent lab as well as a research joint venture we show that 1 demands are interdependent and hence the standard price mechanism is not the profit maximizing licensing strategy 2 the seller s incentives to develop the innovation may be excessive 3 the seller s incentives to disseminate the innovation typically are too low 4 larger ventures are less likely to develop the innovation and more likely to restrict its dissemination in those cases where development occurs and 5 a downstream firm that is not a member of the research venture is worse off as a result of the innovation

dyed in the wool an empirical note on fan loyalty this article attempts to investigate empirically the strength of intracity football club support and seeks to test the commonly held belief among the sports community that supporters will not switch allegiance between city rivals very readily to test this phenomenon data on the attendances of five english and two italian city rival clubs is used to conduct a cointegration analysis the results imply that a stable relationship does not exist between the attendance series which throws doubt on the proposition that supporters of a team are unlikely to switch their support to a rival club to test the possibility that this result could be due to fickle supporters ceasing to attend a sensitivity analysis is conducted between attendances and performance

social desirability of free entry a bilateral oligopoly analysis abstract this paper explores the social desirability of free entry by analyzing a bilateral oligopoly model with bargaining that incorporates the entry process of firms we demonstrate that free entry in an industry producing a homogeneous final product leads to a socially insufficient number of firms when the suppliers of the intermediate products have sufficiently strong bargaining power this is in contrast to previous findings in the theoretical industrial organization literature which demonstrate that in homogeneous final product markets with cournot oligopoly and fixed set up costs level of entry in the free entry equilibrium is always socially excessive our analysis yields an important policy implication given that the standard excess entry result has often been used as a justification for apparently anti competitive entry regulations

innovation market structure and welfare many writers subscribe to joseph schumpeter s view that while perfectly competitive firms allocate resources efficiently in a static sense they perform poorly when it comes to innovation from this point of view the optimal form of market structure is unlikely to be perfect competition but some other type of dynamic competition which includes significant elements of monopoly recently considerable effort has been focused on modelling schumpeter s notion of competition perhaps best exemplified by the 1980 work of partha dasgupta and joseph stiglitz hereafter d s 2 this approach views free entry to the rd see nelson and winter 1977 3readers will recognize a similarity of this approach with the notion of contestable markets discussed most recently by william baumol 1982 and by baumnol john panzar and robert willig 1982 for an interesting comparison of the schumpeterian with the marxian notion of competition see john elliott 1980 4this was noted for example by robert wilson 1975 5in such industries the long term gains from dynamically efficient innovation become of paramount importance consequently the optimal market structure would consist of a small number of firms the driving force behind such a result is what scherer 1972 has called the lebensraum effect firms performing r d must at least break even they derive their profits from

on the fit of new keynesian models this article provides new tools for the evaluation of dynamic stochastic general equilibrium dsge models and applies them to a large scale new keynesian model we approximate the dsge model by a vector autoregression and then systematically relax the implied cross equation restrictions and document how the model fit changes we also compare the dsge model s impulse responses to structural shocks with those obtained after relaxing its restrictions we find that the degree of misspecification in this large scale dsge model is no longer so large as to prevent its use in day to day policy analysis yet is not small enough to be ignored

on the effects of entry in cournot markets in the framework of symmetric cournot oligopoly this paper provides two minimal sets of assumptions on the demand and cost functions that imply respectively that as the number of firms increases the minimal and maximal equilibria lead to i decreasing industry price and increasing or decreasing per firm output and ii increasing industry price and decreasing per firm output in both cases per firm profits are decreasing the analysis relies crucially on lattice theoretic methods and yields general unambiguous and easily interpretable conclusions of a global nature as a byproduct of independent interest new insight into existence of cournot equilibrium is developed

attendance at australian rules football a panel study the demand for australian rules football is examined using data on attendance at individual matches played between 1981 and 1986 an estimation methodology which is appropriate for a dynamic model with panel data is adopted and it is found that attendance at football is price inelastic and an inferior good the effect of habit in consumption behaviour stadium size uncertainty of outcome and team success are also shown to be important determinants of attendance

production functions in the sports industry an empirical analysis of professional cricket production functions are estimated for english county cricket using samples of data for the county championship and the john player league in the seasons of 1981 83 results suggest possible lessons for the management and conduct of the game at the level of the individual club in particular the allocation of resources for developing playing skills the composition of playing staffs selection of teams for particular games and strategies on the field results also provide statistical evidence for some points of conventional wisdom regarding the professional game

bertrand competition when rivals costs are unknown the conclusions of the bertrand model of competition are substantially altered by the presence of asymmetric information about rivals costs asymmetric information eliminates the discontinuity in the bertrand model and significantly alters the properties of the market equilibrium in the bertrand nash equilibrium when rivals costs are unknown firms price above marginal cost and have positive expected profit the analysis is extended to franchise competition the market equilibrium is sensitive to market structure and yields incentives for entry copyright 1995 by blackwell publishing ltd

attendance demand and core support evidence from limited overs cricket in this paper we construct and estimate a model for match attendances in english one day limited overs league cricket our dataset separates pay at gate spectators from club members enabling us to distinguish between the attendance decisions of casual spectators and those of the potentially more committed core supporters in addition to providing a more direct analysis of the relatively underdeveloped issue of core support we also investigate variability within the core apart from providing further evidence regarding demand determination in professional team sports we consider some specific policy implications particular to the peculiar sport of cricket
