what drives deregulation economics and politics of the relaxation of bank branching restrictions this paper investigates private interest public interest and political institutional theories of regulatory change to analyze state level deregulation of bank branching restrictions using a hazard model we find that interest group factors related to the relative strength of potential winners large banks and small bank dependent firms and losers small banks and the rival insurance firms can explain the timing of branching deregulation across states during the last quarter century the same factors also explain congressional voting on interstate branching deregulation while we find some support for each theory the private interest approach provides the most compelling overall explanation of our results

factor productivity and income inequality a general equilibrium analysis economic growth over the past two decades has failed to reduce income inequality we contend that major reasons for this are the slowdown and bias in technological change productivity growth given the complexity of the many interactions that take place this phenomenon is best addressed in a general equilibrium context for this purpose we have developed a computable general equilibrium cge model with advanced features relating to income distribution we perform a series of simulations based on recent overall productivity changes but under various forms of technological change bias factor mobility and government budgetary balance we find the labour augmenting technological change cases to be most consistent with recent experience

the political economy of corporate control and labor rents in a democracy a political majority can influence both the corporate governance structure and the return to human and financial capital we argue that when financial wealth is sufficiently concentrated there is political support for high labor rents and a strong governance role for banks or large investors the model is consistent with the great reversal phenomenon in the first half of the twentieth century we offer evidence that in several financially developed countries a financially weakened middle class became concerned about labor income risk associated with free markets and supported a more corporatist financial system

the politics of financial development evidence from trade liberalization incumbents in various industries have different incentives to promote or oppose financial development changes in the relative strength of promoter and opponent industries thus result in changes in the political equilibrium level of financial development we conduct an event study using a sample of 41 countries that liberalized trade during 1970 to 2000 and show that the strengthening of promoter relative to opponent industries resulting from liberalization is a good predictor of subsequent financial development the benefits of developing the financial system are insufficient for financial development and rents in particular hands appear to be necessary to achieve it copyright c 2008 by the american finance association

the finance growth nexus evidence from bank branch deregulation this paper provides evidence that financial markets can directly affect economic growth by studying the relaxation of bank branch restrictions in the united states we find that the rates of real per capita growth in income and output increase significantly following intrastate branch reform we also argue that the observed changes in growth are the result of changes in the banking system improvements in the quality of bank lending not increased volume of bank lending appear to be responsible for faster growth

a status based model of market competition this article explores the significance of status processes for generating and reproducing hierarchy among producers in a market it develops a conception of a market as a status order in which each

the economics of the greenhouse effect the recognition that economic activity is contributing to climatic change with attendant costs that may be of large magnitudes has set in motion a substantial research effort this paper seeks to review the contribution of economics to analysis of the greenhouse effect and to the policies and instruments suggested as means of mitigating its damage a brief overview of the causes and consequences of global warming is given and a number of energy economy forecasting models are examined as the costs of global warming depend upon the extent to which preventative and adaptive measures are undertaken the techniques available to evaluate these costs are surveyed we examine extant targets for greenhouse gas emissions reduction and explore the frameworks within which optimal policy targets can be designed the paper also considers the narrower question of minimized abatement costs and surveys the types of models used to estimate them the merits of alternative policy instruments are examined paying particular attention to the role that risk and uncertainty and the costs of monitoring and implementation of policy under conditions of imperfect information may play in the choice of instruments problems of international co operation in the development of abatement policy are examined and we consider the compensations across both nations and generations that are likely to be necessary conditions for effective action

privatization in eastern europe irreversibility and critical mass effects abstract this paper proposes a model to shed light on two important policy features of privatization in central and eastern europe the idea of a necessary critical mass of privatization on one hand and the great difficulties encountered in the actual privatization process on the other the model incorporates a positive externality related to the size of the private sector multiple equilibria may arise for political and economic reasons policies of free distribution are analysed with the model they may eliminate the danger of policy reversals due to excess unemployment but may at the same time increase the relative cost of restructuring leading in some cases to pareto inferior outcomes

financial markets the pattern of industrial specialization and comparative advantage evidence from oecd countries due to underlying technological and organizational differences industries differ in their need for external finance since services provided by the financial sector are largely immobile across countries the pattern of industrial specialization should be influenced by the level of financial development among oecd countries we find a strong causal effect of the financial sector on industrial specialization further the financial sector is a source of comparative advantage in a way consistent with the hecksher ohlin vanek model results are also presented on which aspects of financial systems are important for specialization and comparative advantage

the dangerous obsession with cost competitiveness and the not so dangerous obsession with competitiveness judging solely by the continued prevalence of the term in policy makers discourse paul krugman s now famous warnings as to the dangerous obsession of competitiveness have fallen on deaf ears in this paper i argue that this is at least in part because policy makers as distinct perhaps from business school gurus never understood competitiveness in quite the manner he assumed i suggest that krugman largely misdiagnosed the problem of competitiveness directing us to the link between competitiveness and protectionism that was always less prevalent and more tenuous than he imagined as a consequence he overlooked other more pertinent and problematic aspects of the discourse of competitiveness that persist relatively unchallenged in spite of his warnings more specifically i seek to show that krugman s understanding of competitiveness is insufficiently differentiated and rests on inferences drawn from an overly stylised model of competition for market share in product markets that exhibit a high demand price elasticity and in which success is associated exclusively with strategies of cost containment as i show through a series of extensions to his model this leads him to fail to see that it is the privileging of cost competitiveness specifically rather than the pursuit of competitiveness per se that is the dangerous obsession from which we most need protecting today

the profitability concentration relation market power or efficiency industrial economists have been studying the relationship between profitability and concentration using cross industry samples for many years now however as sometimes happens once it appeared that some consensus had been achieved with few exceptions market concentration and industry profitability are positively correlated peltzman i977 p 229 people began to question the interpretation of those results in particular demsetz e g i973 i974 and others suggested that rather than concentration market power leading to higher prices and profits the causal direction in fact ran from greater efficiency to both higher profits and incidentally to higher concentration our purpose here is to subject these conflicting hypotheses to cross industry empirical test using u k data in order to do this we first develop a model which is sufficiently general to allow for both alternative explanations of a positive concentration profitability correlation in the light of this model we then examine the implications for the within industry relation between market share and firm level profitability more specifically we explore demsetz s claim that the empirical form of this relationship should signal which of the alternative hypotheses is consistent with the between industry profitability concentration correlation our model suggests that in certain special circumstances this claim is partly justified in that it should be possible to assess the relative strengths of the market power and efficiency effects from the within industry relation more generally however factors such as product differentiation and scale economies may seriously impair the information content of the relation with at least a strong suspicion that the estimates will tend to exaggerate the evidence in favour of the efficiency hypothesis in the event our results tend to confirm that for most industries the within industry data offer little conclusive support for either hypothesis but for a not insignificant minority of industries the evidence suggests some support for the view that both efficiency and market power are at work simultaneously our model is detailed in section ii and estimated on u k data in section iii after which we offer a few comments in section iv first however we drovide a backcloth to the later analysis

business cycles and the relationship between concentration and price cost margins using a newly constructed panel data base we examine changes in price cost margins in 284 manufacturing industries between 1958 and 1981 a key finding is a dramatic narrowing of the spread between the margins of concentrated and unconcentrated industries over this period we provide evidence that this narrowing is a result of the greater sensitivity of price cost margins in more concentrated industries to demand fluctuations this finding is robust to the inclusion of other industry variables and to measures of import competition the results indicate that cross sectional estimates of the concentration margins relationship are likely to be both biased and misleading

social incidence and economic costs of carbon limits a computable general equilibrium analysis for switzerland this paper discusses both distributional and allocational effects of limiting carbon dioxide emissions in a small and open economy it starts from the assumption that switzerland attempts to stabilize its greenhouse gas emissions over the next 25 years and evaluates costs and benefits of the respective reduction program from a methodological viewpoint this paper illustrates how a computable general equilibrium approach can be adopted for identifying economic effects of cutting greenhouse gas emissions on the national level from a political economy point of view it considers the social incidence of a greenhouse policy it shows in particular that public acceptance can be increased and economic costs of greenhouse policies can be reduced if carbon taxes are accompanied by revenue redistribution

the role of social capital in financial development to identify the effect of social capital on financial development we exploit social capital differences within italy in high social capital areas households are more likely to use checks invest less in cash and more in stock have higher access to institutional credit and make less use of informal credit the effect of social capital is stronger where legal enforcement is weaker and among less educated people these results are not driven by omitted environmental variables since we show that the behavior of movers is still affected by the level of social capital of the province where they were born

law finance and firm growth we investigate how differences in legal and financial systems affect firms use of external financing to fund growth we show that in countries whose legal systems score high on an efficiency index a greater proportion of firms use long term external financing an active though not necessarily large stock market and a large banking sector are also associated with externally financed firm growth the increased reliance on external financing occurs in part because established firms in countries with well functioning institutions have lower profit rates government subsidies to industry do not increase the proportion of firms relying on external financing the corporate finance literature suggests that market imperfections caused by conflicts of interest and informational asymmetries between corporate insiders and investors constrain firms in their ability to fund investment projects the magnitude of these imperfections depends in part on the effectiveness of the legal and financial systems because these systems differ across countries the literature implies that there should exist systematic cross country differences in firms ability to obtain external capital to finance investment in this paper we examine whether the underdevelopment of legal and financial systems does prevent firms in some countries from investing in potentially profitable growth opportunities in particular we focus on the use of long term debt or external equity to fund growth see our earlier work demirgut kunt and maksimovic 1996a which compares firms financial structures in developed and developing countries and finds the greatest difference to be in the provision of long term credit we estimate a financial planning model to obtain the maximum growth rate that each firm in our thirty country sample could attain without access to long term financing we then compare these predicted growth rates to growth rates realized by firms in countries with differing degrees of development in their legal and financial systems our approach enables us to identify specific characteristics of the legal and financial systems that are associated with long term financing of firm growth thus we provide a micro level test of the hypoth

application of computable general equilibrium cge to climate change mitigation policy a systematic review abstract with the growing literature related to climate change mitigation measures and policy interventions a systematic review of the application of computable general equilibrium cge model is inevitable therefore this article aims to characterise the relevant studies define a comparative framework to identify the current state of the art and the gaps in applied general equilibrium models firstly the systematic review found a total of 301 research articles from scopus and web of science databases and finally analysed 154 articles based on inclusion and exclusion criteria from 67 refereed journals the review analysis found that application of cge model is very vital in addressing climate change mitigation issues at the national regional and global levels however china attracted the most substantial research interests followed by the usa india and australia among others which are in line with their share of greenhouse gas emissions in the world most of the research themes focus on the carbon tax emission reduction target emission trading renewable energy energy efficiency and carbon capture and storage as primary drivers of low carbon economy nevertheless there is a trend of employing more static cge model compared to the dynamic cge although application of the latter has a limitation of providing right inputs to the macroeconomic policy finally research directions and gaps envision other complementary models such as dynamic stochastic general equilibrium dsge and agent based model abm for proper policy interventions

capital market imperfections and countercyclical markups theory and evidence during recessions output prices seem to rise relative to wages and raw material prices one explanation is that imperfectly competitive firms compete less aggressively during recessions that is markups of price over marginal cost are countercyclical the authors present a model of countercyclical markups based on capital market imperfections during recessions liquidity constrained firms boost short run profits by raising prices to cut their investments in market share the authors provide evidence from the supermarket industry in support of this theory during regional and macroeconomic recessions more financially constrained supermarket chains raise their prices relative to less financially constrained chains copyright 1996 by american economic association

economic development as self discovery in the presence of uncertainty about what a country can be good at producing there can be great social value to discovering costs of domestic activities because such discoveries can be easily imitated we develop a general equilibrium framework for a small open economy to clarify the analytical and normative issues we highlight two failures of the laissez faire outcome there is too little investment and entrepreneurship ex ante and too much production diversification ex post optimal policy consists of counteracting these distortions to encourage investments in the modern sector ex ante but to rationalize production ex post we provide some informal evidence on the building blocks of our model

carbon reducing taxes and income inequality general equilibrium evaluation of alternative energy taxation in taiwan recently several studies have been a detailed evaluation of the economic implications of energy taxation as a policy instrument to conserve energy and reduce carbon emissions however little attention has been devoted to inquiring about the economic implications of energy taxation in the newly industrialized countries the so called nics in this paper we use a multisector multihousehold computable general equilibrium model to assess the distributional effects of alternative energy taxation on the taiwan economy the counterfactual simulation technique is applied to investigate the income distribution implications of 1 an increase in the import taxes of crude oil and 2 an increase in the excise taxes of petroleum products our empirical results basing on taiwan s data show that both energy taxes increase government revenue and the gini coefficient but reduce net value added private consumption disposable income and equivalent variation a raise in the gini coefficient implies that there is a

welfare effects of emission taxes in norway abstract the welfare effects of introducing taxes on emissions of carbon dioxide is analysed within an empirical general equilibrium model of the norwegian economy a co 2 tax regime where we aim at stabilizing the co 2 emissions at the 1990 emission level in 2020 is compared to a reference scenario without such taxes in the simulations introduction of co 2 taxes reduces gross domestic product but increases net national real disposable income private consumption and money metric utility this difference in sign is due to a positive terms of trade effect some of the co 2 taxes will be paid by foreigners through exports the welfare effects differ from household to household depending on the composition of their total consumption poor households are less favourably affected than rich households due to smaller budget shares for the rich households on consumer goods which imply relatively much co 2 emissions

estimation of a hedonic price equation for bordeaux wine does quality matter in this paper the hedonic price technique is applied to bordeaux wine in the hedonic price function we include not only the objective characteristics appearing on the label of the bottle but also the sensory characteristics of the wine our data come from an experimental study in which juries have evaluated and graded a sample of bordeaux wines the estimation of the hedonic price equation shows that the market price is essentially determined by the objective characteristics the estimation of a jury grade equation shows that quality unlike the market price is essentially determined by the sensory characteristics

culture openness and finance abstract differences in culture proxied by differences in religion and language cannot be ignored when examining why investor protection differs across countries we show that a country s principal religion predicts the cross sectional variation in creditor rights better than a country s natural openness to international trade its language its income per capita or the origin of its legal system catholic countries protect the rights of creditors less well than protestant countries a country s natural openness to international trade mitigates the influence of religion on creditor rights culture proxies are also helpful in understanding how investor rights are enforced across countries

energy taxation as a policy instrument to reduce co2 emissions a net benefit analysis abstract this study evaluates the costs and benefits of energy taxation as a policy instrument to conserve energy and reduce co2 emissions the study combines economic cost estimates generated with a cge model and monetary estimates of environmental damages in a comprehensive cost benefit framework we find that optimal co2 emissions reductions range from 5 to 38 depending on different assumptions about energy substitution elasticities and environmental damages co2 emissions reductions of between 8 and 64 can be attained at no additional welfare cost relative to a policy of not undertaking any action to control co2 emissions

finance and the sources of growth the authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources total factor productivity growth physical capital accumulation and private saving they use 1 a pure cross country instrumental variable estimator to extract the exogenous component of banking development and 2 a new panel technique that controls for country specific effects and endogeneity they find that banks do exert a large causal impact on total factor productivity growth which feeds through to overall gdp gross domestic product growth the long run links between banking development and both capital growth and private savings are more tenuous

linear sam models for inequality changes analysis an application to the extremadurian economy social accounting matrices are adequate databases for the economic modelling these matrices emphasize the role of households in the economy and so they usually disaggregate the household sector into several groups this disaggregation allows social accounting matrices to be used for diverse income distribution analysis the objective of this work is to use the linear sam models to study how inequality is modified by several exogenous injections of income the set of multipliers and indicators presented is applied to the economy of extremadura a region situated in the southwest of spain in particular together with the accounting multipliers two redistributed income matrices are presented to show how changes in final demand and in income transfers cause opposite effects in inequality for contrasting these results gini and theil indices are also used finally a major reduction in both would result from an appropriate re allocation of transfers
