competition and social influence the diffusion of the sixth generation processor in the global computer industry1 when is a social actor most strongly influenced by its peers this article addresses this question by clarifying when computer firms were most strongly affected by the choices of their structurally equivalent rivals to adopt a well known technology intel s sixth generation processor the core hypothesis is that the effect of adoptions by structurally equivalent firms increases with the competitive pressure that a focal firm faces in its market position the results show that a chosen firm is most strongly influenced by comparable others when it faces scale based competition and is diversified the implications of this study are twofold a social actor s sensitivity to the conduct of others may depend not only on its place in a hierarchy but also on the nature of its ties to an external audience and a contingent theory of social influence may be necessary to characterize diffusion processes correctly particularly when external and time varying nonnetwork factors have significant effects

energy efficiency investments in the context of split incentives among french households the residential sector offers considerable potential for reducing energy use and greenhouse gas ghg emissions particularly through energy efficient renovations the objective of this study is twofold first i aim to provide initial empirical evidence of the extent to which split incentives between landlords and tenants may lead to underinvestment second i investigate the influence of tax credits and energy burdens on energy efficiency expenditures given the complexity of studying the decision to invest in energy saving renovations i use a bivariate tobit model to compare decisions about energy efficient works and repair works even when the renovation expenditures seem quite similar the analysis shows that tenants are doubly penalized they have high energy expenditures due to energy inefficient building characteristics and because they are poorer than homeowners they are unable to invest in energy saving systems the results also confirm that tax credits are ineffective in the split incentives context in terms of public policy the government should focus on low income tenants and mandatory measures such as minimum standards seem appropriate financial support from a third party financer also might be a solution

benefits conditional on work and the nordic model abstract welfare benefits in the nordic countries are often tied to employment we argue that this is one of the factors behind the success of the nordic model where a comprehensive welfare state is associated with high employment in a general equilibrium setting the underlining mechanism works through wage moderation and job creation the benefits make it more important to hold a job thus lower wages will be accepted and more jobs created moreover we show that the incentive to acquire higher education improves further boosting employment in the long run these positive effects help in counteracting the negative impact of taxation through numerical simulations we show how this mechanism can contribute to explain the better labor market performance and more equitable income distribution of nordic countries compared to continental european ones

corporate conservatism and relative compensation this paper demonstrates that in a simple setting with managerial concern for reputation and asymmetric information on ability most managers may refrain from undertaking innovations that stochastically dominate an industry standard common components of uncertainty lead to market inferences of managerial ability based on relative performance managers who undertake the industry standard are consequently evaluated with a more accurate benchmark than those innovating discontinuities in compensation when performance is low because of firings lead managers to have differing valuations of an accurate benchmark depending on type in particular very high and very low ability managers are more likely to undertake superior innovations than those of average ability

unemployment growth and taxation in industrial countries unemployeement and taxes do taxes affect the rate of umemployeement to the layman the upward trend in european unemployment is related to the slowdown of economic growth we argue that the layman s view is correct the increase in european unemployment and the slowdown in economic growth are related because they stem from a common cause an excessively rapid growth in the cost of labour in europe labour costs have gone up for many reasons but one is particularly easy to identify higher taxes on labour if wages are set by strong and decentralized trade unions an increase in labour taxes is shifted onto higher real wages this has two effects first it reduces labour demand and thus creates unemployment secondly as firms substitute capital for labour the marginal product of capital falls over long periods of time this in turn diminishes the incentive to invest and to grow the data strongly support this view according to our estimates the observed rise of 14 percentage points in labour tax rates between 1965 and 1995 in the eu could account for a rise in eu unemployment of roughly 4 percentage points a reduction of the investment share of output of about 3 percentage points and a growth slowdown of about 0 4 percentage points a year francesco daveri and guido tabellini

wage and price control policies in transition economies abstract this paper studies the structural impact of wage and price control policies in transition economies using a two sector three factor small open economy model it illustrates the results quantitatively via simulation exercises at the earlier stage of the transition when labor is immobile a strict control on the price of the nontradables and the wage rate minimizes the fall in employment and output also a more severe control on the price of the nontradables than on the wage rate alleviates the fall in the real wage at negligible costs in lost employment and output at the later stage of the transition when labor becomes mobile the liberalization of the price of the nontradables can proceed faster than that of the wage rate this policy combination increases employment and output and reduces the shortage for the nontradables but lowers the real wage

dynamics of dyadic competitive interaction in this study of firms entries into and exits from each other s markets we link research on multipoint competition to the emerging action oriented dyadic approach to interfirm rivalry by specifying market interdependencies between pairs of firms that condition their potential for rivalry over time our dynamic analysis of competitive interactions between pairs of commuter airlines in california reveals the idiosyncratic and asymmetric market microstructures that characterize dyadic competitive relationships and helps explain why firms grapple vigorously with some of their competitors while being passive toward others we show that there is an inverted u shaped relationship between firms rates of entry into and exit from each other s markets and the level of multimarket contact in competitor dyads we also show how this basic curvilinear effect varies from dyad to dyad as a function of relative levels of multimarket contact with competitors in other dyads and the relative sizes of competitors in a focal dyad copyright 1999 john wiley sons ltd

evidence of direct and indirect rebound effect in households in eu 27 countries abstract this research estimates the direct and indirect rebound effect of energy efficiency in households for the eu 27 countries the first twenty seven member states of the european union a hybrid methodology that combines econometric estimates environmental extended input output analysis and re spending models has been developed although most of the economies present values below 100 there are seven countries situated above this critical threshold by weighting individual estimates by gdp an average value for the overall eu 27 economy has been found between 73 62 and 81 16 these results suggest that the energy policy at the european level should be rethought if efficiency measures pursue reducing energy consumption and tackling climate change

market barriers to energy efficiency abstract discussions of energy policy in an environmentally constrained world often focus on the use of tax instruments to internalize the external effects of energy utilization or achieve specified reductions in energy use in the most cost effective manner a substantial literature suggests however that significant opportunities exist to reduce energy utilization by implementing technologies that are cost effective under prevailing economic conditions but that are not fully implemented by existing market institutions this paper examines the theory of the market for energy using equipment showing that problems of imperfect information and transaction costs may bias rational consumers to purchase devices that use more energy than those that would be selected by a well informed social planner guided by the criterion of economic efficiency consumers must base their purchase decisions on observed prices and expectations of post purchase equipment performance if it is difficult or costly for individuals to form accurate and precise expectations the level of energy efficiency achieved by competitive markets will vary from the socially efficient outcome such market barriers suggest a role for regulatory intervention to improve market performance at prevailing energy prices

youth labor market expectations and job matching in sub saharan africa evidence from school to work transition surveys in this paper we investigate the factors that influence youth labour market expectations and outcomes we also perform a job matching exercise to understand youth labour market dynamics in sub sah

ethnic unemployment rates and frictional markets the unemployment rate in france is roughly 6 percentage points higher for african immigrants than for natives in the us the unemployment rate is approximately 9 percentage points higher for blacks than for whites commute time data indicates that minorities face longer commute times to work potentially reflecting more difficult access to jobs in this paper we investigate the impact of spatial mismatch on the unemployment rate of ethnic groups using the matching model proposed by rupert and wasmer 2012 we find that spatial factors explain 1 1 5 percentage points of the unemployment rate gap in both france and the us amounting to 17 25 of the relative gap in france and about 10 17 5 in the us among these factors differences in commuting distance play the most important role in france though longer commuting distances may be mitigated by higher mobility in the housing market for african workers overall we still conclude that labor market factors remain the main explanation for the higher unemployment rate of africans

the spread of the multidivisional form among large firms 1919 1979 the multidivisional form is the favored form of organization for the large firms that dominate the american economy this study takes up the causes of the dissemination of that form among large firms from 1919 to 1979 five theories are initially proposed as possible explanations for the changes observed and these theories are operationalized and tested the model that seems most consistent with the data emphasizes the ability of key actors to alter structure under three circumstances when the firm has a product related or unrelated strategy which is consistent with chandler s 1962 theorizing when the corporate presidents have a background in sales or finance and when other firms in the industry alter their structures the implications of these results for theories of organizational change are discussed with special reference to the importance of conceiving how actors operate with varying rationalities in this process

restraining energy demand the stick the carrot or the market abstract following the 1973 arab oil embargo and continuing through the 1980s the us regulators at both the state and federal levels tried a number of schemes to encourage energy conservation in all sectors of the economy particularly in the electric power sector although these efforts resulted in significant energy efficiency improvements the utilities were not overly enthusiastic because of the negative impact of lower sales on their revenues and profits from 1989 several trend setting states in the usa introduced generous profit incentives to reward utilities financially for undertaking aggressive dsm programmes the impact of these new dsm incentives has been quite noticeable and they are expected to produce significant reductions in the growth rate of demand for electricity in states where they are available this paper reviews the success and some of the problems associated with dsm incentive mechanisms in the usa and provides some policy options for overseas countries interested in learning from the us experience

between markets and politics organizational responses to reform in china in china s economic transition firms diversify assets through investments in the rapidly expanding service sector in response to organizational uncertainty using data from a random sample of firms in shanghai the author shows that there are two situations that cause this uncertainty economic instability where weak firms struggle to survive in the rapidly changing market system and administrative instability where large firms that were the most protected are now being forced to handle the responsibilities that were previously handled by the state the result is that both types of firm seek stability by spreading out risk through investment in low risk fast return markets revealing much about the economic reforms the overall strategy of a firm reflects at any given point in time important organizational facts any decision to fundamentally alter the deployment of internal resources represents a major structural change these kinds of changes do not occur often when they do they provide us wit

reducing energy demand a review of issues challenges and approaches most commentators expect improved energy efficiency and reduced energy demand to provide the dominant contribution to tackling global climate change but at the global level the correlation between increased wealth and increased energy consumption is very strong and the impact of policies to reduce energy demand is both limited and contested different academic disciplines approach energy demand reduction in different ways emphasising some mechanisms and neglecting others being more or less optimistic about the potential for reducing energy demand and providing insights that are more or less useful for policymakers this article provides an overview of the main issues and challenges associated with energy demand reduction summarises how this challenge is framed by key academic disciplines indicates how these can provide complementary insights for policymakers and argues that a sociotechnical perspective can provide a deeper understanding of the nature of this challenge and the processes through which it can be achieved the article integrates ideas from the natural sciences economics psychology innovation studies and sociology but does not give equal weight to each it argues that reducing energy demand will prove more difficult than is commonly assumed and current approaches will be insufficient to deliver the transformation required

oscillating currents the changing rationale for government intervention in the electricity industry the appropriate role for government in the electricity industry has emerged as a major issue throughout the world this is explained using the terms of neoclassical economics by shifts in the rationales for government intervention in that industry the two historic rationales natural monopoly and public good have been diminishing in importance while the need to deal with negative environmental externalities has been given increasing attention this paper details the changes in each rationale and then synthesizes this information to probe the implications for policy a key conclusion is that while there will be pressures toward similar policy responses and similar models for the electricity sector there will remain opportunities and justification for significant differences between regions and countries

transaction costs of tradable white certificate schemes the energy efficiency commitment as case study this paper analyses the nature and scale of transaction costs tcs borne by obliged parties under a tradable white certificate twc scheme taking the first phase of the energy efficiency commitment eecl in great britain as a case study several sources of tcs were considered such as search for information persuasion of customers negotiation with business partners and measurement and verification activities information was obtained through interviews and a questionnaire distributed to obliged parties results show that the most significant sources of tcs were related to search for information persuading customers and negotiating with managing agents contractors to implement energy efficiency measures perceived high tcs related to contract negotiation and liability risks slightly reduced the low trading level the scale of tcs was estimated to be around 10 and 30 of total investments costs for the lighting and insulation segments respectively the results indicate that despite the presence and scale of tcs the eecl scheme generated energy savings that yielded net societal benefits estimated financial benefits range from 0 6 to 6 p kwh for insulation and lighting savings respectively when avoided external costs due to electricity savings are included estimated economic benefits range from 3 to 8 p kwh several lessons from the eecl can be drawn for twc schemes among others it is found that informative policy instruments to raise awareness among end users are critical if a twc scheme is to deliver cost effective energy savings in all the nature and scale of tcs under twc schemes will differ because of a number of endogenous and exogenous determinants c 2007 elsevier ltd all rights reserved less

structural transformation and the deterioration of european labor market outcomes this paper examines hours worked in continental europe and the united states from 1956 to 2003 the empirical work establishes two results first hours worked in europe decline by almost 45 percent compared to the united states over this period second this decline is almost entirely accounted for by the fact that europe develops a much smaller market service sector than the united states a simple model of time allocation is used to understand these patterns i find that relative increases in taxes and technological catch up can account for most of the differences between the european and american time allocations over this period

energy conservation policies abstract an increased efficiency of energy use often equated with increased conservation is widely believed to be an important factor in constraining consumption of fossil fuels in the light of fears of global warming this mistaken belief is founded on the fall in energy gdp ratios observed since 1973 interpreted as a decoupling of energy from economic growth energy conservation is only one of a number of factors contributing to this fall in general increasing efficiency of use will lead to reduced costs which in turn promotes a greater usage if global warming is to be taken seriously restrictions on fossil fuel consumption may have to be imposed by measures such as the carbon tax proposed by the international energy agency

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

technical evidence for assessing the performance of markets affecting energy efficiency abstract this paper focuses on the empirical basis for skepticism about the effectiveness of the market mechanism in promoting cost effective energy efficiency improvements we present a framework for evaluating engineering economic evidence on the diffusion of energy efficiency improvements and then present a series of examples within this framework that provide evidence for the existence of market imperfections related to energy efficiency we conclude with a challenge to economists policy analysts and technologists to take this empirical evidence seriously and sponsor further collaborative research in this area

estimating direct and indirect rebound effects for u s households with input output analysis part 2 simulation abstract this is the second part of a two part paper that integrates economic and industrial ecology methods to estimate the indirect rebound effect from residential energy efficiency investments we apply the model developed in part one to simulate the indirect rebound given an estimate of the direct rebound using a 2002 environmentally extended input output model and the 2004 consumer expenditure survey in 2002 for the u s we find an indirect rebound of 5 15 in primary energy and co 2 e emissions assuming a 10 direct rebound depending on the fuel saved with efficiency and household income the indirect rebound can be as high as 30 40 in no x or so 2 emissions for efficiency in natural gas services the substitution effect modeled in part one is small in most cases and we discuss appropriate applications for proportional or income elasticity spending assumptions large indirect rebound effects occur as the u s electric grid becomes less carbon intensive in households with large transportation demands or as energy prices increase even in extreme cases there is limited evidence for backfire or a rebound effect greater than 100 enacting pollution taxes or auctioned permits that internalize the externalities of energy use would ensure that rebound effects unambiguously increase consumers welfare

the effects of an increase in energy efficiency on the kenya economy abstract there are reasons to believe that improved energy efficiency still is an important energy development policy despite stable oil prices abundant oil supplies and end of the cold war the political reasons are uncertainty of the current gulf situation and prevalent wars in the former eastern bloc countries increasing concern over global environmental problems the existence of imperfect energy markets and the desire for rapid economic growth in developing countries are the other reasons this paper analyses the effects of energy management policies on the kenyan economy using a computable general equilibrium model simulations show that an increase in energy efficiency leads to reduced dependence on foreign energy sources promotion of reliable domestic energy sources promotion of conservation of all forms of energy saves scarce foreign currency and preserves the environment

evaluating innovation and labour market relationships the case of italy in this paper the link between labour market flexibility and innovation is analysed paying particular attention to the different technological regimes of economic activities and the different geographical areas of the italian economy a dynamic panel data specification is used to assess the endogenous relationship between patents included as a proxy of the innovation and job turnover and wages which represent labour market indicators the results show that higher job turnover only has a significant and negative impact on patent activities in regional sectors of northern italy while a positive and significant impact of blue and white collar wages has been generally found

the myths and facts of energy efficiency abstract the debate about how much energy efficiency is socially desirable and what is the best way to finance and implement energy conservation measures has reached a critical junction in many countries the arguments have passed the stage of whether more energy efficiency is possible or desirable and are centred around how much and how best to implement them this is a survey article which attempts to shed some light on several critical issues in this debate first it distinguishes between what is technically possible v what is economically desirable in energy efficiency improvements second it looks at some of the alleged causes of social under investment in energy efficiency and identifies ways to reduce or eliminate them third it addresses the question of who is best equipped to implement energy efficiency improvements and how one may go about promoting it finally the paper addresses critical financing and equity questions

improving the energy efficiency of buildings the impact of environmental policy on technological innovation abstract this paper investigates the impact of alternative environmental policy instruments on technological innovations aiming to improve energy efficiency in buildings the empirical analysis focuses on three main types of policy instruments namely regulatory energy standards in buildings codes energy taxes as captured by energy prices and specific governmental energy r d expenditures technological innovation is measured using patent counts for specific technologies related to energy efficiency in buildings e g insulation high efficiency boilers energy saving lightings the estimates for seven european countries over the 1989 2004 period imply that a strengthening of 10 of the minimum insulation standards for walls would increase the likelihood to file additional patents by about 3 in contrast energy prices have no significant effect on the likelihood to patent governmental energy r d support has a small positive significant effect on patenting activities

technology policy interaction in frictional labour markets does capital embodied technological change play an important role in shaping labour market outcomes to address this question we develop a model with vintage capital and search matching frictions where irreversible investment in new vintages of capital creates heterogeneity in productivity among firms matched as well as vacant we demonstrate that capital embodied technological change reduces labour demand and raises equilibrium unemployment and unemployment durations in addition the presence of labour market regulations unemployment benefits payroll taxes and firing costs exacerbates these effects thus the model is qualitatively consistent with some key features of the european labour market experience relative to that of the u s it features a sharper rise in unemployment and a sharper fall in the vacancy rate and the labour share a calibrated version of our model suggests that this technology policy interaction could explain a sizeable fraction of the observed differences between the u s and europe copyright 2007 wiley blackwell

the role of product market regulations in the process of structural change abstract the sectoral allocation of labor differs considerably across developed economies even in the presence of similar patterns of structural change a general equilibrium model that captures the stylized facts of structural change is presented in this framework economy wide product market regulations hinder the development of dynamic sectors such as service industries this is consistent with the negative cross country relationship between product market regulations and the service employment share discussed in the paper additionally the model suggests that higher service prices and rents in regulated economies reduce labor supply providing a rationale for the negative association between product market regulations and the employment rate previously found in the literature

managerial cognition and the mimetic adoption of market positions what you see is what you do managers planning to abandon a market position need to find a promising alternative and face a choice of inventing a new market position or entering an existing one the great uncertainty on the consequences of different actions leads them to rely on other organizations for information on how to compete making adoption of existing market positions likely their wish to avoid direct rivalry and maximize growth leads them to seek out information on new market positions with few incumbents as a result recently innovated market positions are mimetically adopted by organizations that can easily observe previous adoptions and see them as relevant to their market situations increasing the market differentiation this theory is tested and supported by analysis of the spread of new radio formats in the united states 1998 john wiley sons ltd

jevons paradox revisited the evidence for backfire from improved energy efficiency beginning with william stanley jevons in 1865 a number of authors have claimed that economically justified energy efficiency improvements will increase rather than reduce energy consumption jevons paradox is extremely difficult to test empirically but could have profound implications for energy and climate policy this paper summarises and critiques the arguments and evidence that have been cited in support of jevons paradox focusing in particular on the work of len brookes and harry saunders it identifies some empirical and theoretical weaknesses in these arguments highlights the questions they raise for economic orthodoxy and points to some interesting parallels between these arguments and those used by the biophysical school of ecological economics while the evidence in favour of jevons paradox is far from conclusive it does suggest that economy wide rebound effects are larger than is conventionally assumed and that energy plays a more important role in driving productivity improvements and economic growth than is conventionally assumed

how much market do market based instruments create an analysis for the case of white certificates in the context of economic instruments for more energy efficiency and climate protection tradable certificates have been investigated for renewable energy and for a number of emissions in contrast tradable energy efficiency or white certificates have only lately been considered as a market based tool to foster energy efficiency as compared to standards and labelling for example theoretically there is little doubt about the advantages in practice however some fundamental problems arise critical issues are the design of an efficient artificial market for white certificates its compatibility with the european emissions trading system the identification of a suitable target group for an energy efficiency obligation and the measurement of energy savings as compared to a reference use of energy we use the theoretical framework of transaction cost economics to elaborate these issues we conclude that transaction costs and investment specificity will restrict markets for white certificates in practise long term contracts rather than spot trade will be the prevailing form of governance for energy efficiency investments

empirical estimates of the direct rebound effect a review beginning with william stanley jevons in 1865 a number of authors have claimed that economically justified energy efficiency improvements will increase rather than reduce energy consumption jevons paradox is extremely difficult to test empirically but could have profound implications for energy and climate policy this paper summarises and critiques the arguments and evidence that have been cited in support of jevons paradox focusing in particular on the work of len brookes and harry saunders it identifies some empirical and theoretical weaknesses in these arguments highlights the questions they raise for economic orthodoxy and points to some interesting parallels between these arguments and those used by the biophysical school of ecological economics while the evidence in favour of jevons paradox is far from conclusive it does suggest that economy wide rebound effects are larger than is conventionally assumed and that energy plays a more important role in driving productivity improvements and economic growth than is conventionally assumed 2008 elsevier ltd all rights reserved

living up to expectations estimating direct and indirect rebound effects for uk households this study estimates the combined direct and indirect rebound effects from various types of energy efficiency improvement by uk households in contrast to most studies of this topic we base our estimates on cross price elasticities and therefore capture both the income and substitution effects of energy efficiency improvements our approach involves estimating a household demand model to obtain price and expenditure elasticities of different goods and services utilising a multiregional input output model to estimate the ghg emission intensities of those goods and services combining the two to estimate direct and indirect rebound effects and decomposing those effects to reveal the relative contribution of different mechanisms and commodities we estimate that the total rebound effects are 41 for measures that improve the efficiency of domestic gas use 48 for electricity use and 78 for vehicle fuel use the primary source of this rebound is increased consumption of the cheaper energy service i e direct rebound and this is primarily driven by substitution effects our results suggest that the neglect of substitution effects may have led prior research to underestimate the total rebound effect however we provide a number of caveats to this conclusion as well as indicating priorities for future research

the role of shocks and institutions in the rise of european unemployment the aggregate evidence two key facts about european unemployment must be explained the rise in unemployment since the 1960s and the heterogeneity of individual country experiences while adverse shocks can potentially explain much of the rise in unemployment there is insufficient heterogeneity in these shocks to explain cross country differences alternatively while explanations focusing on labour market institutions explain current heterogeneity well many of these institutions pre date the rise in unemployment based on a panel of institutions and shocks for 20 oecd nations since 1960 we find that the interaction between shocks and institutions is crucial to explaining both stylised facts

beyond energy efficiency and individual behaviours policy insights from social practice theories abstract this conceptual paper deals ultimately with the intricate relationships existing between quantity and quality in the field of energy conservation policies it discusses how current policy approaches to energy conservation have energy efficiency and individuals behavioural change as principle target it then argues that their limited impacts derive largely from how they are principally informed by quantitative estimates of reductions in energy inputs and neglect how qualitative changes generated in the energy outputs can either offset these reductions e g more energy efficient motors can enable the production of larger cars consuming more energy or cause higher savings e g smaller cars can consume less energy even with less efficient motors the paper also explains these limited impacts in terms of overly simplistic cause effect relationships assumed to exist between given exogenous factors e g provision of information price signals etc and individuals behaviours it then shows how radically alternative policies for energy conservation can target qualitative changes and re organisations in energy outputs in doing so it takes social practice theories as theoretical background finally it discusses the potentially very high impacts and the alternative character of policies informed by these theories and shows how and where they indicate to intervene

density dependence in the evolution of populations of newspaper organizations a model of density dependence is proposed to explain regularities in the growth and decline of organizational populations density the number of organizations is assumed to be a function of the social processes of legitimation and competition at low density the model predicts that the legitimation process will dominate and will lead to high organizational founding rates and low organizational mortality rates at high levels of density competition will dominate and consequently founding rates will decline and mortality rates will rise the model is tested with hazard function models using data from nine newspaper populations spanning the 19th and 20th centuries and covering over 5200 newspapers analysis offounding rates provides strong empirical support for the model analysis of mortality rates reveals that the model holds for large populations

understanding european unemployment with a representative family model abstract a representative family model with indivisible labor and employment lotteries has no labor market frictions and complete markets nevertheless its aggregate responses to an increase in government supplied unemployment insurance ui and to an increase in microeconomic turbulence are qualitatively similar to those in two macromodels with labor market frictions and incomplete markets namely the matching and search island models in ljungqvist and sargent 2007a understanding european unemployment with matching and search island models journal of monetary economics this issue because there is no frictional unemployment in the representative family model an increase in employment protection ep decreases aggregate work because the representative family substitutes leisure for work an effect opposite to what occurs in matching and search island models heterogeneity among workers highlights the economy wide coordination in labor supply and consumption sharing that employment lotteries and complete markets achieve in the representative family model a high disutility of labor makes generous ui cause very low employment levels

the impact of employment tax cuts on unemployment and wages the role of unemployment benefits and tax structure abstract i model and simulate the effects of employment tax cuts on unemployment and wages in four equilibrium models competitive union bargaining search and efficiency wages i find that if the ratio of unemployment compensation to wages is fixed the effect of the tax cut is mainly on wages but if income out of work is fixed in real terms there are substantial employment effects when wages are determined by bargaining revenueneutral reforms that make the tax more progressive also reduce unemployment thus policy towards unemployment compensation and tax structure are key influences on the effect of taxes on unemployment

learning from the behavior of others conformity fads and informational cascades learning by observing the past decisions of others can help explain some otherwise puzzling phenomena about human behavior for example why do people tend to converge on similar behavior why is mass behavior prone to error and fads the authors argue that the theory of observational learning and particularly of informational cascades has much to offer economics business strategy political science and the study of criminal behavior

human capital and unemployment dynamics why more educated workers enjoy greater employment stability why do more educated workers experience lower unemployment rates and lower employment volatility empirically these workers have similar job finding rates but much lower and less volatile separation rates than their less educated peers we argue that on the job training being complementary to formal education is the reason for this pattern using a search and matching model with endogenous separations we show that investments in match specific human capital reduce incentives to separate but leave the job finding rate essentially unaffected the model generates unemployment dynamics quantitatively consistent with the data finally we provide novel empirical evidence supporting the mechanism studied in the paper this article is protected by copyright all rights reserved

barriers within firms to energy efficient investments abstract many investments in energy efficiency fail to be made despite their apparent profitability internal hurdle rates are often set at levels higher than the cost of capital to the firm reasons for these practices include bounded rationality principal agent problems and moral hazard the policy implication is that government can simultaneously improve overall energy efficiency and increase private sector productivity by providing informational and organizational services that go beyond the traditional regulatory framework

demand uncertainty mismatch and un employment we consider a finite number of firms which compete imperfectly for heterogeneous workers firms produce a homogeneous good sold on a competitive market and face demand induced price fluctuations it is then shown that unemployment may arise in equilibrium because of both uncertainty of product demand and job mismatch unemployment does not arise however when the variance of the demand shock is small enough and or the cost of mismatch is sufficiently low full employment always prevails when there is free entry hence unemployment may persist as long as the incumbent firms choose their skill requirements to protect their supernormal profits

renewable energy policy and electricity restructuring a california case study abstract many countries are in the process of deregulating and restructuring their electric power industries although the introduction of retail competition may have negative impacts on the development of renewable energy a number of countries are establishing new programs to support these clean energy technologies in the united states debate has centered on three primary renewables support mechanisms 1 the renewables portfolio standard 2 programs funded by an electricity distribution surcharge and 3 voluntary renewable energy purchases by electricity customers via green power marketing california provides a good case study of the design of renewables support programs within industry restructuring because policymakers considered all three of these options during the state s restructuring proceedings moreover many of the same policy options design issues and political conflicts that have arisen in california are likely to recur in other states and countries some of the most important lessons from the california experience include 1 renewable energy and environmental advocates must clearly articulate the need and rationale for continued support of renewables 2 cost containment and competitive neutrality concerns must be addressed head on 3 combinations of policies are likely to be far more effective than any single renewables policy and 4 the effectiveness of renewable energy policies developed during the restructuring process will be strongly linked to their duration and stability

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

unemployment responses to skill biased technology shocks the role of labour market policy do skill biased shocks that increase the spread of labour productivities interacting with different policy regimes explain the rise in unemployment in europe relative to the united states in the 1980s and 1990s the hypothesis is an implication of a version of the mortensen and pissarides 1994 model of equilibrium unemployment which allows for worker heterogeneity a calibrated version of the model implies that a similar unemployment increase would have occurred in the united states over this period given changes in relative productivity by education implied by observed wage changes had unemployment compensation and employment protection policies been at european levels

anatomy of a future energy crisis restructuring and the energy sector in new zealand abstract up until the mid 1980s new zealand had been characterized by an economy that was heavily protected extensively regulated and in which production was subsidized to a considerable extent in 1984 the government embarked upon a programme of extensive public sector and economic restructuring described by some as being among the most wide reaching and radical in new zealand s history for the energy sector the restructuring has meant a move away from an administrative infrastructure of the 1970s and 1980s that was strongly centralized and government led to one that is based much more on market forces energy development production and delivery have been corporatized and privatized the energy sector has been largely deregulated and government has disavowed itself of responsibility for energy resource management and policy the primary motivation that underlies all of the reform is economic efficiency concerns are widely held however for the implications that follow from this restructuring of the energy sector for the efficient management of energy resources security of supply long term management of the sector and for the maintenance of environmental quality it is possible that greater economic efficiencies might be achieved although this is by no means certain but it would seem that specific characteristics of the restructuring will militate strongly against the achievement of other objectives in the sector recommendations for amendment refer to the need to strike a sensible balance between market forces and government involvement

earnings unemployment and the allocation of time over time since an individual s labour market history can be described by a markov chain in state space it is possible to calculate the steady states it is natural to interpret the steady state proportion in unemployment for a group of identical workers as the natural rate of unemployment for this group i e it is the expected proportion that would be employed if the environment were to remain constant it is shown how the natural rate of unemployment is different for different groups the model is estimated using data from a large u s income maintenance experiment the predictions of the model with some exceptions bear up well to confrontation by data the empirical findings also accord well with existing evidence on cross section studies of labour supply we find that labour force participation rates implied by the estimated models are positively related to earnings for all age sex and race groups as expected we demonstrate that the elasticities of the unemployment rates for all groups with respect to expected wage rates are negative and large in absolute value in the case of adults while the role of the wage in allocation of time is not novel the existing neoclassical labour literature uses static labour supply models to interpret participation rate studies

should unemployment benefits decrease with the unemployment spell abstract in this paper we investigate whether unemployment benefits should decrease with the unemployment spell in a model where both job search intensity and wages are endogenous wages are set by collective agreements bargained by insiders it is shown that a more declining time sequence of unemployment benefits leads to wage increases when the tax rate is given such an effect may imply an increase in unemployment and counteracts the response of job search intensity that can be found in standard job search models with a given wage distribution calibration exercises suggest that it costs twice as much in terms of welfare loss for the long term unemployed workers to reduce the unemployment rate by 1 when wages are endogenous than in the standard job search model

public acceptability of personal carbon trading and carbon tax abstract climate change is one of the greatest challenges confronting the international community requiring action to achieve deep cuts in carbon emissions the implementation of potentially uncomfortable but necessary policy measures is though critically dependent upon public acceptability this paper reports a novel application of stated preference techniques to explore the influence of key design attributes on the acceptability of a personal carbon trading scheme in isolation and when compared to a carbon tax illustrative forecasts from the models developed indicate the importance of design attributes especially the basis of the initial permit allocation for personal carbon trading and the use to which revenues are put for carbon tax results indicate that the best scheme designs could be acceptable to a majority of respondents

institutions and performance in european labour markets taking a fresh look at evidence this paper presents a selective survey of the recent literature on labour market institutions and offers new empirical eu based evidence on the impact of labour market reforms on employment and labour market adjustment although the literature traditionally treats labour market institutions as exogenous attention shifted recently towards understanding the underlying causes of specific institutional arrangements as a consequence the literature highlights the great importance of an efficient policy design exploiting these interactions wisely and identifies general principles for achieving an efficient policy design at both macro and micro levels although empirical evidence does not show a major change in terms of intensity of labour market reform after the setting of the economic and monetary union and the creation of the euro the reforms aiming at strengthening the labour market attachment of vulnerable groups tend to have been successful both in raising their employment and increasing labour market adjustment

market failure and energy policy a rationale for selective conservation abstract appropriate activities for the government in the energy sector of the us economy are suggested on the basis of market failures in this sector alleged market failures are explored and specifically targeted remedies proposed where indicated the resulting government policies can be characterized as selectively conservationist designed to induce lower levels of use of particular fuels sometimes in particular industries

incentives precision technology and environmental protection abstract this paper calls for a reevaluation of the pollution problem in order to devise efficient strategies for its control it contends that a fundamental cause of pollution is inefficiency in input use during the production process this inefficiency manifests itself as input waste and polluting residues precision technologies can increase the effectiveness of inputs used in production and reduce pollution generation despite their potential economic and ecological benefits adoption of precision technologies has been slow this paper presents a conceptual framework to identify and analyze the specific factors that affect their diffusion among microunits these include various heterogeneous characteristics of microunits prices which do not reflect the relevant scarcities due to distortionary regulatory policies and lack of institutional mechanisms for efficient allocation of inputs and outputs it rationalizes the observed variations in the appropriate choice of technology across microunits and argues for the need to broaden the range of incentive based instruments for environmental protection beyond pollution taxes

interdependent behavior in foreign direct investment the multi level effects of prior entry and prior exit on foreign market entry this paper examines the interdependent foreign market entry decisions of multinational corporations mncs based on the argument that legitimacy and competition are two important forces in foreign market entry decisions we hypothesize that an mnc s market entry decisions are influenced by its own prior entry and prior exit decisions and those of other mncs we examine this general proposition at four levels of analysis the host country global industry an industry that spans host countries local industry an industry that is separately defined within each host country and parent firm level our analysis of a panel data of over 4000 market entry decisions that were made by japanese mncs shows that an mnc s market entry decision has a stronger inverted u shaped relationship with the prior entry and exit decisions of other mncs at the local industry level than the prior entry and exit decisions of other mncs at the host country and global industry levels we also find that both the prior entry and prior exit decisions of an mnc have a marginal influence on its own subsequent market entry decisions at the parent firm level

on the inefficiency of matching models of unemployment with heterogeneous workers and jobs when firms rank their applicants in a circular matching model with bargained wages firms rank their applicants and pick the most suitable one job creation appears to lower the average output as firms do not internalize this effect there are too many jobs in a laissez faire equilibrium under the hosios condition by contrast job rejection is efficient for the equilibrium value of market tightness consequently introducing unemployment compensation raises the aggregate income by lowering market tightness due to the isomorphism between the two models these results extend to match specific productivities however competitive search restores market efficiency

sales at risk a test of the mutual forbearance theory of conglomerate behavior in seeking to understand the implications of the large amount of diversification and conglomeration that has occurred in the united states since the mid 1960s some economists have revived the mutual forbearance hypothesis first presented by edwards 1955 several papers have attempted to formalize or test this hypothesis which states that multimarket contacts mmcs among firms have the potential for facilitating collusion in one or more of the markets where these contacts occur using 1976 data from the federal trade commission s line of business study an earlier paper feinberg 1982 developed a framework for evaluating mmcs and inthis paper tests the mutual forbearance theory of conglomerate behavior at both company and industry levels using 1976 data from the federal trade commission s line of business program this theory states that companies meeting rivals in more than one market will be able to facilitate collusion in one or all of those markets at the company level the evidence supports the theory showing salesat risk a measure of the importance of multimarket contacts to increase price cost margins in the moderate range of concentration where collusion is feasible but difficult to achieve without mutual forbearance the industry level results are weaker casting some doubt on the hypothesis associate professor of economics pennsylvania state university this paper was begun while i was a consultant to the line of business program at the federal trade commission the manager of the line of business program has certified that he has reviewed and approved the disclosure avoidance procedures used by the staff of the line of business program to insure that the data included in this paper do not identify individual company line of business data views expressed here are my own and not necessarily those of the federal trade commission i would like to thank william long george pascoe david ravenscraft melvin reder and an anonymous referee for their help on this project 1 these studies often refer to terms other than mutual forbearance e g spheres of influence extended interdependence they include adams 1974 reynolds 1976 heggestad and rhoades 1978 areeda and turner 1979 strickland 1980 feinberg 1982 1984 scott 1982 and feinberg and sherman 1985

search mismatch and unemployment abstract this paper explores the efficiency of the equilibrium allocation in a matching model with heterogeneous workers and jobs in the basic setup there are two types of workers with different skill levels both types can perform the simple tasks of unskilled jobs while the complex tasks of skilled jobs require a high ability worker we demonstrate that the equilibrium outcome with random search and ex post bargaining is never efficient under the hosios condition the average wage is correct but bargaining compresses the wage distribution relative to workers shadow values this feature distorts the relative profits of jobs making it too attractive for firms to create skilled jobs furthermore due to the low skill premium the high ability workers may accept too many jobs finally in an extension we show that the introduction of separate markets for the two types of jobs is not sufficient to guarantee efficiency

the structure of competition how competition between one s rivals influences imitative market entry this paper investigates how the pattern of encounters between a firm s competitors affects the firm s inclination to follow its competitors into a new market we theorize that direct encounters between a firm s rivals lead to a herding effect making imitative market entry more likely past mutual forbearance between a firm s competitors resulting from asymmetric multimarket competition further strengthens this herding effect by enhancing the firm s expectations of market attractiveness in contrast aggressive past rivalry between the competitors resulting from symmetric multimarket contact dampens these expectations producing a competition effect that makes herding less probable we test our idea in two distinct contexts the chinese pharmaceutical industry and the taiwanese computer hardware industry and find consistent support in both settings we discuss how our analysis of what we call the structure of competition can be extended to research on other forms of firm behavior

the split incentives energy efficiency problem evidence of underinvestment by landlords abstract due to asymmetric information between landlords and renters landlords with tenants who pay the utility bill underinvest in energy efficiency measures using data from the 2009 residential energy consumption survey i present empirical evidence that this underinvestment occurs in multiple categories of residential energy efficiency space heating water heating window thickness insulation and weatherization because these landlords did not invest at the same rate as homeowners and landlords who pay the energy bill their tenants energy bill was higher by nearly 2 when combined with other researchers estimations for appliances davis 2010 insulation and thermostat responsiveness for tenants gillingham et al 2012 our results imply that renters use approximately 2 7 more energy overall due to the landlord tenant split incentive issue

excess worker reallocation workers face a trade off between macroeconomic and individual incentives to work in different occupations industries namely between search frictions and personal comparative advantages workers endowed with heterogeneous multi dimensional skills search for jobs that require different skill combinations in equilibrium specialized individuals contact few selected types of vacancies where they are likely to be hired those with weak comparative advantages are seldom chosen among competing applicants thus seek any job type in a tight labour market comparative advantages dominate waiting costs offsetting labour mobility across industries occupations excess worker reallocation is lower and matches are more successful consistently with direct and indirect evidence

competition in a multimarket environment the case of market exit studies of competition typically have two underlying assumptions that competition occurs within the boundaries of industries or markets and that all firms in a market or industry are affected equally by competitive pressures the concept of multipoint competition challenges both assumptions multipoint theory addresses how different levels of contact between firms across multiple markets affect competition in individual markets its main argument is that high levels of contact between firms across markets will induce mutual forbearance causing multipoint competitors to refrain from aggressively attacking each other the restraint stems from the fact that high levels of intermarket contact enable a firm to respond to an aggressive action by a multipoint rival in markets other than the one in which the action takes place that possibility raises the potential costs of aggressive moves and serves as a credible deterrent especially if a firm can respond in several markets in addition multipoint competiti

does child labour displace schooling evidence on behavioral responses to an enrollment subsidy this brief summarizes the results of a gender impact evaluation study entitled does child labour displace schooling evidence on behavioral responses to an enrollment subsidy conducted between 1995 and 1996 in bangladesh the study observed that the subsidy increases schooling but its effect on child labour is ambiguous the subsidy increased schooling by far more than it reduced child labour substitution effects helped protect current incomes from the higher school attendance induced by the subsidy substitution effects helped protect current incomes from the higher school attendance induced by the subsidy the reduction in the incidence of child labour by boys girls represents about one quarter eighth of the increase in their school enrollment rate

two questions about european unemployment a general equilibrium search model makes layoff costs affect the aggregate unemployment rate in ways that depend on equilibrium proportions of frictional and structural unemployment that in turn depend on the generosity of government unemployment benefits and skill losses among newly displaced workers the model explains how before the 1970s lower flows into unemployment gave europe lower unemployment rates than the united states and also how after 1980 higher durations have kept unemployment rates in europe persistently higher than in the united states these outcomes arise from the way europe s higher firing costs and more generous unemployment compensation make its unemployment rate respond to bigger skill losses among newly displaced workers those bigger skill losses also explain why u s workers have experienced more earnings volatility since 1980 and why especially among older workers hazard rates of gaining employment in europe now fall sharply with increases in the duration of unemployment

two views on the deterioration of european labor market outcomes this paper challenges the consensus view on the deterioration of european labor market outcomes relative to the united states when looking at employment to population ratios rather than unemployment rates i find that the deterioration begins in the mid 1950s and continues through the mid 1990s i also present evidence to suggest that the key to understanding this deterioration is to understand why europe has not developed a market service sector similar to the united states jel e2 j2

on the unprofitability of utility demand side conservation programmes abstract this paper analyses the economic prospects of demand side conservation programmes the essence of various proposals is that conservation measures should be a part of least cost planning at least if marginal production costs are high and consumers decisions are distorted market failures the weakness of this literature is that it assumes that the consumers remain passive when the utilities invest in conservation this paper remedies this deficiency and considers strategic interactions between consumers and a public utility stackelberg equilibria it will be shown that strategic interactions render unprofitable demand side conservation programmes that appear profitable by conventional criteria the reason is that rational consumers will respond strategically to the prevalence of utility sponsored conservation programmes by minimizing their own expenses for energy efficiency

a review of demand side management policy in the uk abstract demand side management dsm refers to actions undertaken on the demand side of energy metres a broad definition of dsm is proposed to include current policy objectives for emissions reduction energy security and affordability and encompasses energy efficiency demand response and on site back up generation and storage the paper reviews the concept of dsm outlines the historical impacts of dsm globally since the energy crises of the 1970s analyses uk dsm policy and examines the influence of eu directives on uk dsm policy as the country is currently deciding on how to include the demand side in its electricity market reform proposals and wider energy policy much of the focus of previous research has been on dsm technological trials and modelling studies rather than dsm policy and the paper contributes to filling this gap policy recommendations for the uk context are discussed and it is clear that the success of dsm policies is determined primarily by regulatory support and utility financial incentives it is important that policy clarity is provided and that current and new policies do not overlap

unemployment insurance and cultural transmission theory and application to european unemployment this paper emphasizes the two way causality between the provision of unemployment insurance and the cultural transmission of work ethic values affect the size of the moral hazard problem and hence the policy to be implemented conversely when parents rationally choose how much effort to exert to raise their children to work hard they form expectations on the policy that will be implemented by the next generation in this context we show that the different cultural traits are complementary and that there is some cultural heterogeneity in all steady state equilibria the model could generate a lag between the introduction of unemployment insurance and a deterioration of the work ethic relying on a calibration we argue that it can account for a substantial fraction of the history of european unemployment since world war ii as our explanation is compatible with the co existence of generous unemployment insurance and low unemployment in the 1950s and 1960s it could be seen as an alternative to the dominant story that relies on the occurrence of large shocks since the 1970s supportive empirical evidence is provided

organizational processes to meet new performance criteria chinese pharmaceutical firms in transition abstract the current crisis in china s state owned enterprises presents a paradox of performance since reforms began in the early 1980s many state owned enterprises are producing and selling more some even reporting increasing profits recent discussions of the crisis facing these firms however reveal that most of the gains in these performance outcomes has been achieved without regard for efficiency in many cases simply by increasing inputs only now has the government explicitly recognized the need to shift emphasis from measures of performance based on scale whether output sales or profits to those incorporating considerations of efficiency return on output sales and assets we investigate the managerial and policy implications of such a shift in key performance criteria using longitudinal data on 66 chinese pharmaceutical manufacturers we find that both the level and growth in physical assets are the strongest correlates of scale based performance measures in contrast activities which bring in engineering skills lead to new product development and increase the proportion of output that is actually sold are the strongest correlates of efficiency based performance measures for managers and policymakers these results have important implications for the timing and level of investment in particular organizational activities and resources

how to deal with the rebound effect a policy oriented approach policy makers and environmental agencies have echoed concerns brought forward by academics about the need to address the rebound effect for achieving absolute energy and environmental decoupling however such concerns have generally not been translated into tangible policy action the reasons behind this inaction are not fully understood and much remains unknown about the status of the rebound effect issue on the policy agenda and policy pathways available such knowledge gaps may hamper the development of effective policies to address this issue in this paper we examine the extent to and ways in which the rebound effect is considered in policy documents and analyse thirteen specific policy pathways for rebound mitigation the effectiveness of the pathways is scrutinised and conclusions are offered to mitigate rebound effects the main policy conclusions of the paper are that an appropriate policy design and policy mix are key to avoiding undesired outcomes such as the creation of additional rebound effects and environmental trade offs from the discussion economy wide cap and trade systems as well as energy and carbon taxes when designed appropriately emerge as the most effective policies in setting a ceiling for emissions and addressing energy use across the economy

labor search and matching in macroeconomics abstract the labor search and matching model plays a growing role in macroeconomic analysis this paper provides a critical selective survey of the literature four fundamental questions are explored how are unemployment job vacancies and employment determined as equilibrium phenomena what determines worker flows and transition rates from one labor market state to another how are wages determined what role do labor market dynamics play in explaining business cycles and growth the survey describes the basic model reviews its theoretical extensions and discusses its empirical applications in macroeconomics the model has been developed against the background of difficulties with the use of the neo classical frictionless model of the labor market in macroeconomics its success includes the modelling of labor market outcomes as equilibrium phenomena the reasonable fit of the data and when inserted into business cycle models improved performance of more general macroeconomic models at the same time there is evidence against the nash solution used for wage setting and an active debate as to the ability of the model to account for some of the cyclical facts

living by the golden rule multimarket contact in the u s airline industry this paper examines empirically the effects of multimarket contact on pricing in the u s airline industry the analysis of the time series and cross sectional variability of airline fares in the 1000 largest domestic city pair routes reveals the presence of statistically significant and quantitatively important multimarket effects fares are higher in city pair markets served by carriers with extensive interroute contacts these findings are consistent with the claims of industry experts that airlines live by the golden rule i e that they refrain from initiating aggressive pricing actions in a given route for fear of what their competitors might do in other jointly contested routes during his testimony mr steven b elkins senior director of marketing systems development for northwest airlines cited an example in which northwest lowered fares on night flights that were flying with empty seats in a number of routes from minneapolis and upper midwest cities to various west coast cities he said that continental airlines swiftly responded by cutting prices in important northwest markets mr elkins s memo advises northwest pricing analysts we will live by the golden rule in his testimony he explained that the golden rule in that context was that i did not want my pricing analyst initiating actions in another carrier s market like chicago for fear of what that other carrier might do to retaliate wall street journal october 9 1990 p b1

experience imitation and the sequence of foreign entry wholly owned and joint venture manufacturing by south korean firms and business groups in china 1987 1995 the evolution of foreign entry in the form of joint ventures and wholly owned manufacturing operations is examined as a staged process shaped by experience and imitation dynamics at the firm group and industry levels of analysis the expansion of south korean firms into china between 1987 and 1995 lends support to the staged view of foreign entry over time technology intensive firms are more likely to abandon joint venture entry modes owing to contractual hazards firms in the same business group are found to imitate each other s choice of joint ventures and wholly owned plants firms in the same industry mimic each other s choice of wholly owned plants though not of joint ventures

the determinants of equilibrium unemployment the paper takes the search and matching model of the aggregate labor market to the data it tests the model s empirical validity and employs structural estimation to generate a characterization of the optimal behavior of firms and workers the model is applied to israeli data that are uniquely suited for this kind of empirical investigation the structural estimates are used to quantify the frictions embodied in the model including the costs of search the congestion and trading externality effects and the matching process a calibration simulation analysis then studies the effect of several key variables on equilibrium unemployment
