environmental regulation and u s economic growth in this article we quantify the costs of pollution controls by reporting the results of simulations of the growth of the u s economy with and without regulation for this purpose we have constructed a detailed model of the economy that includes the determinants of long term growth we have also analyzed the interaction between industries in order to capture the full repercussions of environmental regulations however we have not attempted to assess the benefits resulting from a cleaner environment we find that pollution abatement has emerged as a major claimant on the resources of the u s economy the cost of emission controls is more than 10 of the total cost of government purchases of goods and services

incentives productivity and labor contracts the relationship between age earnings profiles and worker incentives is examined by contrasting wage and salary workers with the self employed it is argued that the steepness of wage and salary workers age earnings profiles reflects the desire to provide work incentives to those workers since self employed workers do not face this agency problem they are used as a benchmark to gauge productivity empirical support of the proposition is provided and the effects of human capital accumulation are separated empirically from incentive effects the most important conclusion is that under some strong assumptions most of the slope in age earnings profiles is accounted for by the desire to provide incentives rather than by on the job training

electric power sector reform liberalization models and electric power prices in developing countries an empirical analysis using international panel data this study aims to clarify whether the effects of electric power sector reforms should be different either across regions or between developing and developed countries an empirical model was analyzed to observe the impact of electric power prices on the selection of a liberalization model in the power sector this was achieved by the use of an ordered response fixed effect and a random effect model an instrument variable technique was also used to estimate the impact of the liberalization model on the electric power price this technique addressed the problems of simultaneity bias between the electric power price and the liberalization models selected these econometric models were designed using panel data from 78 countries in four regions developed countries asian developing countries the former soviet union and eastern europe and latin america for the period from 1985 to 2003 the research findings suggest that higher electricity prices are one of the driving forces for governments to adopt liberalization models however the development of liberalization models in the power sector does not necessarily reduce electricity prices in fact contrary to expectations there was a tendency for the price to rise in every market modeled

energy market liberalization and renewable energy policies in oecd countries abstract this paper investigates the effect of energy liberalization compared to other drivers on policies that support renewable energy in a long panel of oecd countries we estimate this effect by accounting for the endogeneity of liberalization related to joint decisions within a country s energy strategy using regulation in other industries as instruments we find that energy liberalization increases public support for renewable energy the effect of liberalization is the second largest after the effect of per capita income and is mostly driven by reductions in entry barriers while the effect of privatization is unclear this finding suggests that a reduction in the monopolistic power of state owned utilities has a positive effect on renewable energy policies when various types of actors are ensured access to the grid instead of it being provided to only a few large private firms

liberalisation and r d in network industries the case of the electricity industry abstract electricity sector liberalisation has coincided with a significant decline in r d spending this paper reviews the industrial organisation literature on r d and innovation to explore the likely causes of the decline in r d spending in the electricity sector meanwhile r d productivity and innovative outputs in utilities and equipment suppliers appear to have improved however a lasting decline in r d expenditure can have a negative long term effect on technological progress and innovation in the sector we conclude that the decline in r d could have been predicted from the literature we also discuss the need to reorient the post liberalisation technology policy

energy transition poverty and inequality in vietnam this paper investigates energy transition energy poverty and energy inequality in vietnam employing a longitudinal dataset of a nationally representative household survey we use the data on residential energy expenditure of more than 9 000 households over the period 2004 2016 we find a transition from traditional energy to modern energy but this transition varies across regions between ethnic and welfare groups and between rural and urban population the poor and ethnic minority households still rely heavily on traditional energy sources such as coal and biomass to meet their energy demands electricity poverty has decreased but energy cost poverty has increased in addition energy inequality tends to decrease at a more significant rate than income and consumption inequalities we propose a national program for energy poverty alleviation be established to devise policies to lower households energy costs further assistance to the poor and ethnic minority households is also recommended so that they can afford a higher level of electricity consumption

changes to gate closure and its impact on wholesale electricity prices the case of the uk abstract the electricity supply industry in the united kingdom underwent a number of regulatory reforms since late 80 s that have transformed the trading and pricing of the energy market herein we provide empirical evidence that the modification proposal p12 mod p12 that took place in 7 2 2002 moving the gate closure gc interval from 3 5 h to 1 h before real time has caused a permanent alteration in the uk spot price volatility using a combination of recurrence plot rp and recurrence quantification analysis rqa we find that after the the change in the gc time short term price volatility significantly decreased between 2001 and 2008 while long term price volatility is not affected by cg change similar results are obtained by means of spectral analysis on the price series showing a significant reduction in its variability the results of our analysis suggest that a dynamical regime shift of the price occurred and such shift is linked to the gc change whereby shorter gc intervals facilitate short term forecasting on electricity demand and better reliability on the supply side therefore gc closer to real time is associated to reduced price fluctuations in the wholesale market

the economic consequences of brexit energy in this paper we raise a number of issues that are important for the uk to consider in the light of its decision to leave the european union eu the first of these is the nature of the eu single market in electricity and gas and the uk s role within this the second is the nature of uk energy policy in the light of brexit and the opportunities for changing this and third we consider some of the key issues to be addressed in a negotiating position with the eu

direct measurement of popular price expectations expectations are an important determinant of economic behavior the analysis of economic expectations however has suffered from inadequate measurement throughout the literature expectations have been treated as unobservable and have therefore been measured only indirectly the object of this paper is to develop and test a direct measure of the expectations of inflation a particularly critical economic variable a direct measure of inflationary expectations is here taken to be one constructed from a sample survey in which individuals are asked to state their expectations explicitly the paper focuses on a popular forecast of the rate of change of consumer prices in the forthcoming year as calculated from responses to the survey of consumer finances scf this measure is presented in section i the scf and others like it have existed for some time but a few recent studies notwithstanding most economists continue to regard survey measures as inherently unreliable their principal criticism is that the opinions an individual expresses

conservatism and debt abstract despite the unquestionable influence of conservatism disagreement remains about what economic demands lead to financial reporting conservatism research examining lenders demands for reporting conservatism has been questioned for ignoring conservative contract modifications we document that these modifications exist but are not ubiquitous we find contract modifications are more likely when agency costs are higher and litigation tax and equity demands for conservatism are lower however we find a positive association between unexplained reporting conservatism and contract modifications suggesting contractual modifications alone do not fulfill lenders demands for conservatism

discussion of accounting standards and debt covenants has the balance sheet approach led to a decline in the use of balance sheet covenants abstract demerjian this issue argues that a shift by u s standard setters towards the balance sheet approach reduces the usefulness of balance sheet numbers for contracting consistent with this argument he provides evidence of a decline in the use of balance sheet based covenants in debt contracts a useful finding nevertheless i argue that the evolution of standard setting is more complex than this argument implies and evaluate the economic basis of demerjian s arguments for how debt contracts respond to changes in accounting rules one conclusion that emerges is that there are still some important open issues regarding the economic determinants of debt contracts

technical change and efficiency measures the post privatisation in the gas distribution sector in argentina abstract in this paper we use a stochastic frontier approach to analyse the technical change in the post privatisation period in the gas distribution sector in argentina we found that there is both a catching up effect and a shift in the frontier which shows that the sector as a whole improved its efficiency in the reviewed period moreover this phenomenon holds not only for the average but also for every firm in the sample

real wages over the business cycle evidence from panel data one topic on which keynes did not disagree with classical economists was the cyclical behavior of real wages keynes 1936 as well as various classical writers predicted that real wages should move countercyclically quoting the general theory p 17 in general an increase in employment can only occur through the accompaniment of a decline in real wages thus i am not disputing this vital fact which the classical economists have rightly asserted as indefeasible this prediction is based on the premise of competition and a given short run capital stock increases in employment then correspond to more intensive use of capital and through diminishing product lower real wages for this reason evidence by dunlop 1938 and tarshis 1939 that real wages move procyclically was viewed as paradoxical both dunlop and tarshis based their findings on an observed positive correlation between real and money wages which given the procyclical movement of money wages implies a positive correlation between

the economic consequences of accounting choice implications of costly contracting and monitoring abstract in this paper we review research into the economic consequences of voluntary and mandatory choices of accounting techniques and standards we discuss how the predictions of extant economic consequence theories are driven by contracting and monitoring costs associated with management compensation contracts bond covenants regulation and or political visibility we review empirical tests of economic consequence theories categorize those tests and discuss their strengths and weaknesses the empirical tests reveal two systematic associations with accounting choice size a proxy for political visibility and leverage a proxy for contracting and monitoring costs of lending agreements interpretation of the results is difficult due to general limitations of the tests we conclude by suggesting some directions for future research based on our analysis of the potential payoffs associated with different types of empirical tests

implications for gaap from an analysis of positive research in accounting based on extant literature we review the positive theory of gaap the theory predicts that gaap s principal focus is on control performance measurement and stewardship and that verifiability and conservatism are critical features of a gaap shaped by market forces we recognize the advantage of using fair values in circumstances where these are based on observable prices in liquid secondary markets but caution against expanding fair values to financial reporting more generally we conclude that rather than converging u s gaap with ifrs competition between the fasb and the iasb would allow gaap to better respond to market forces

the role of policy in energy transitions lessons from the energy liberalisation era the aim of this paper is to discuss the period of energy privatisation and liberalisation which began in the 1980s within its wider historical context the key issues are what has been learned from this recent period and how significant is it in the light of an energy transition to low carbon energy system by 2050 energy liberalisation has led to positive and globally widespread but modest efficiency gains but a lack of clearly visible direct benefits to households in many countries it has significantly improved the governance of monopoly utilities via independent regulators the prospects for competition and innovation and the quality of policy instruments for environmental emissions control through the emergence of trading mechanisms we conclude that it is not liberalisation per se that will determine the movement towards a low carbon energy transition but the willingness of societies to bear the cost which will be significant no matter what the extent of liberalisation

winners and losers from the privatization and regulation of utilities lessons from a general equilibrium model of argentina a computable general equilibrium cqe model is used to estimate the macroeconomic and distributional effects of the privatization and regulation of utilities in argentina begun in 1989 based on data available after the privatization that indicate different kinds of efficiency gains in electricity gas water and telecommunications both the privatization and effective regulation are estimated to yield significant macroeconomic benefits gains from the privatization accrue mainly to high income classes while gains from the effective regulation of newly privatized utilities accrue mainly to low income classes computable general equilibrium cge estimates of overall employment effects suggest that privatization was not a major contributor to the dramatic rise in unemployment in argentina between 1993 and 1995 this rise was more likely due to the tequila effect of an interest rate shock

the impact of minimum wages in mexico and colombia there are diverging views about how minimum wages affect labor markets in developing countries advocates of minimum wages hold that they redistribute resources in a welfare enhancing way and can thus reduce poverty improve productivity and foster growth opponents on the other hand contend that minimum wage interventions result in a misallocation of labor and lead to depressed wages in the very sectors the rural and informal urban sectors where most of the poor are found with the effect of wasting resources and reducing the growth rate data from colombia and mexico for the 1980s provide an opportunity to evaluate the impact of minimum wages in mexico in the 1980s the minimum wage fell in real terms roughly 45 percent by 1990 mexico s minimum wage was about 13 percent of the average unskilled manufacturing wage during the same period the minimum wage in colombia increased at nearly the same rate reaching roughly 53 percent of the average unskilled wage the author charts how the mandated minimum wage affected the demand for skilled and unskilled labor in both countries during that decade findings are as follows in mexico minimum wages have had virtually no effect on wages or employment in the formal sector the main reason the minimum wage is not an effective wage for most firms or workers in the informal sector in turn there is considerable noncompliance with the mandated minimum wage especially among part time and female workers as a result significant numbers of workers are paid at or below minimum wages in colombia minimum wages have a much stronger impact on wages judging from their proximity to the average wage and both cross section and time series estimates the estimates imply that the elasticity of low paid unskilled employment with respect to minimum wages is in the range of 2 to 12 percent

incomes policy and wage differentials periodic incomes policies have by now become a feature of most western economies it has also become clear that there is a trade off between the features of an incomes policy that make it initially acceptable and the features that make it ultimately effective for example most british incomes policies of the 1970s have provided higher permissible proportionate wage increases for low wage than for high wage workers as we argue in section ii below the primary advantage and perhaps cause of such policies is that they can more readily secure the ex ante support of a majority of workers for any specified overall increase in the wage bill or inflation target if they are effective however such policies also result in the narrowing of wage differentials and this results in new problems some economists consider such wage equalization the inevitable cost that an economy must bear for the sake of an effective incomes policy others believe the arbitrary narrowing of wage differentials creates industrial relations problems that ultimately cause the incomes policy to fail in either case it is important to know how much equalization has been caused by the actual incomes policies and how this compares with what would have been expected from strictly adhered to policies in consequence the first and major part of this paper contains a simple analysis of the movement of differentials in britain in the last decade most incomes policies have been explicitly equalizing but how much equalization occurred compared with the equalization that would have occurred if the policies had been explicitly adhered to we show that the 1973 formula of 1 plus 4 per cent was associated with the full equalizing effect it implied but the 1975 6 a week was largely submerged in other changes and was associated with less than a third of the equalization implied by the formula indeed such mild equalization as occurred between 1975 and 1977 may be explained partly by the lower inflation rate which reduced that part of the inequality of instantaneous earnings that is caused by different groups of workers settling at different times of year against this higher unemployment may have been tending to increase inequality at the same time in 1974 threshold payments were associated with an effect of about one half of their predicted level the main force that offset the equalizing nature of the threshold formula and the 6 a week was we believe the pressure of employers bidding up the relative earnings of the more skilled workers having looked at the overall picture we then examine more closely which groups have gained and lost from recent changes in relative wages and what equalization has occurred within the different groups the groups are defined by occupation and by collective agreement our general conclusion is that however finely the labour force is subdivided equalization between groups has played a very small role in the overall equalization and the main changes

malmquist indices of productivity change in the uk gas industry before and after privatization the uk government s privatization programme was justified in terms of potential efficiency gains this paper concentrates on measures of technical efficiency in the regions of the uk natural gas industry before and after privatization and the associated regulatory changes it uses non parametric frontier analysis and malmquist indices to show that the rate of productivity growth increased significantly after privatization however the differences in technical efficiency amongst regions remain suggesting that failure to break up the industry has sacrificed potential gains from direct competition or indirect competition through yardstick regulation

inflation stabilization and the vanishing size wage effect the author examines wage patterns under an incomes policy in mexico in 1987 94 the policy specified increases in the minimum wage rate but also guided salary negotiations more generally the author finds indications of a substantial but largely temporary effect on wage rates and evidence consistent with more intensive monitoring of compliance in large firms than in smaller ones for example three years after policy implementation public sector wages had fallen approximately 10 relative to private sector wages and wages in the largest private firms had fallen 15 relative to those in the smallest private firms these relative wage effects are consistent with the centralized administration of the policy

a reconsideration of import substitution this paper studies the origins of an import substitution strategy of development summarizes the consequences of that strategy and reviews the problems that led to its failure the fundamental difficulty was its discouragement of the indigenous social learning necessary for sustained independent development the emergence of an outward oriented minimal government strategy is due to the success of korea and taiwan this strategy fails to recognize that social learning requires a strong role for national agents and that this role can be penalized by undue openness an effective strategy must protect and induce domestic learning without penalizing exporting

varieties of capitalism and the internationalization of state owned enterprises this article sheds light on how the internationalization of state owned enterprises is influenced by the state involvement in ownership and by the home country s institutional settings integrating international business literature with the debate on the varieties of capitalism we contend that state dominated enterprises internationalize more less than privately owned enterprises in coordinated liberal market economies whereas they exhibit an inconstant behavior in state influenced market economies our analysis on a sample of enterprises pertaining to 20 oecd countries supports our hypotheses this article adds to studies on the influence of institutions on firms internationalization and has implications for both managers and policymakers

economic prescriptions for environmental problems how the patient followed the doctor s orders o ne of the dangers with ivory tower theorizing is that it is easy to lose sight of the actual set of problems which need to be solved and the range of potential solutions as one who frequently engages in this exercise i can attest to this fact in my view this loss of sight has become increasingly evident in the theoretical structure underlying environmental economics which often emphasizes elegance at the expense of realism in this paper i will argue that both normative and positive theorizing could greatly benefit from a careful examination of the results of recent innovative approaches to environmental management the particular set of policies examined here involves two tools which have received widespread support from the economics community marketable permits and emission charges pigou 1932 dales 1968 kneese and schultze 1975 both tools represent ways to induce businesses to search for lower cost methods of achieving environmental standards they stand in stark contrast to the predominant command and control approach in which a regulator specifies the technology a firm must use to comply with regulations under highly restrictive conditions it can be shown that both of the economic approaches share the desirable feature that any gains in environmental quality will be obtained at the lowest possible cost baumol and oates 1975 until the 1960s these tools only existed on blackboards and in academic journals as products of the fertile imaginations of academics however some countries have recently begun to explore using these tools as part of a broader strategy for managing environmental problems

accounting information in financial contracting the incomplete contract theory perspective this paper reviews theoretical and empirical work on financial contracting that is relevant to accounting researchers its primary objective is to discuss how the use of accounting information in contracts enhances contracting efficiency and to suggest avenues for future research we argue that incomplete contract theory broadens our understanding of both the role accounting information plays in contracting and the mechanisms through which efficiency gains are achieved by discussing its rich theoretical implications we expect incomplete contract theory to prove useful in motivating future research and in offering directions to advance our knowledge of how accounting information affects contract efficiency

the impact of regulatory quality and corruption on residential electricity prices in the context of electricity market reforms abstract the european electricity markets have been undergoing significant regulatory reforms since the introduction of the first liberalisation directive in 1996 theory predicts that liberalisation promotes cost efficient production and competition and hence leads to lower prices the goal of this paper is to assess the impact of regulatory quality and non compliance with the law on electricity prices in the context of electricity market reforms we address problems of endogeneity by using the blundell blond system gmm estimator and find that vertical integration and market concentration lower end user prices all else equal moreover improving regulatory quality and reducing corruption both have a negative impact on prices when holding other factors constant the intensity of the reforms has limited impact on electricity prices when these reforms are introduced in an institutional environment characterised by high levels of corruption and low quality regulation

do mergers improve efficiency evidence from restructuring the us electric power sector abstract this paper analyses the performance impact of the merger wave which took place in the us electricity industry during the period 1994 2003 it does so by analyzing the impact on operating and total cost in electricity distribution while there are past studies of efficiency and productivity effects as well as of prices profits and other outcomes this study differs in several ways first the database consists of many merging and non merging firms rather than only a few on which to base inferences second all of these mergers arise in a single industry greatly facilitating controlled comparison third we have data on the several years of pre merger and post merger efficiency of the specific merging units unlike virtually all past studies finally we employ a powerful nonparametric technique data envelopment analysis to measure the efficiency of each operating unit the results indicate that electricity mergers are not consistent with improved cost performance

socio technical analysis of the electricity sector of mexico its historical evolution and implications for a transition towards low carbon development abstract the electricity sector of mexico has been found itself in continuous transitions since its beginning in the 19th century however the historical reform to the sector that recently took place together with new energy market configurations around the globe may pose an important challenge to transitioning towards a low carbon sector the work presented here was aimed at understanding in a qualitative manner the complex interactions between the main social technical and environmental aspects that have guided the sector in the past their influence on the current structure and its future development through the application of the multi level perspective mlp with a governance and agency perspective additionally the work tried to elucidate the implications of the incumbent position of the natural gas industry and the possibilities for low carbon technologies the conclusions remark the importance of previous sector configurations in the present structure the important role of government in promoting low carbon technologies together with investment by market actors and the possible window of opportunity that the natural gas industry in mexico may provide to low carbon energy technologies

the role of employer employee interactions in labor market cycles evidence from the self employed self employed workers are less likely to be affected by implicit contracts efficiency wages and other forces that mute wage cyclicality and exacerbate employment cyclicality this observation motivates our comparison of the cyclical experience of the self employed with wage and salary workers who clearly have an employer we find negligible or small differences in annual hours cyclicality between the two groups but hourly wages and annual earnings are much more cyclical for the self employed these results are consistent with efficient contracting models where employers smooth workers income without causing inefficiencies in hours of work

negotiated measurement rules in debt contracts this paper investigates contractual definitions of net income and net worth and the cross sectional variation in definitions of net income in a large sample of private debt contracts to shed light on the debt contracting demand for accounting numbers the descriptive evidence indicates that removing transitory earnings is one principal concern in the measurement of earnings but not in the measurement of net worth in the extreme contracts are never written on comprehensive income as an earnings concept whereas accumulated other comprehensive income is included in net worth in most contracts in contrast conservative adjustment in the sense of including certain types of negative earnings but not the corresponding positive earnings does not seem to be a primary consideration in measuring net income and net worth cross sectionally i find that net income is more likely to be defined differently from the gaap when net income plays a more important role in a contract when the loan maturity is longer and when transitory earnings are less useful for debt contracting collectively the evidence shows that debt contracting parties choose contracting variables in a manner consistent with efficient contracting and that transitory earnings are relatively less useful in measuring firm performance for debt contracting

bridging the gap the design of bank loan contracts and distance how do the distance constraints faced by lenders in acquiring borrower information affect the design of bank loan contracts theoretical studies posit that greater information asymmetry leads to the allocation of stronger ex ante decision rights to the lender the uninformed party consistent with this hypothesis we find that upon inception contracts tend to be more restrictive when firms seek loans from remote lenders this finding is robust to potential endogeneity bias and simultaneity of various loan terms overall we establish a strong informational link between distance and loan contract design

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

the financial and operating performance of privatized firms during the 1990s this study compares the pre and postprivatization financial and operating performance of 85 companies from 28 industrialized countries that were privatized through public share offerings for the period from 1990 through 1996 we document significant increases in profitability output operating efficiency and dividend payments and significant decreases in leverage ratios for our full sample of firms after privatization and for most subsamples examined capital expenditures increase significantly in absolute terms but not relative to sales employment declines but insignificantly combined with results from two previous directly comparable studies these findings strongly suggest that privatization yields significant performance improvements during the past two decades the privatization of state owned enterprises has moved from being a radical almost desperate policy initiative of the thatcher government in britain to being an accepted economic policy for governments of all ideological stripes according to gibbon 1998 860 billion has been raised by governments worldwide through privatizations with the bulk of this total coming since 1987 and at least one commentator roche 1996 predicts that no less than 6 trillion will be raised through privatizations over the next two decades in 1997 alone sales of public enterprises totaled a record 161 billion worldwide with more than 110 billion of the total coming during the second half of the year and 1998 s total of almost 140 billion indicates that the pace shows no sign of slackening as we approach a new millennium

objectives and incentives evidence from the privatisation of great britain s power plants abstract does privatization increase plant productivity because the private owner s objective is different or because they are better able to control management and is privatization sufficient to improve productivity or is it only effective in combination with competition we answer these questions using the quasi experiment of great britain s electricity industry privatization to separate the effect of a change in objectives from a change in incentives we assume that the former only affects labor but not fuel productivity and assuming that effective competition was only introduced after privatization we are able to separately identify the effects of privatization and competition we find that privatization increased labor but not fuel productivity evidence for the importance of objectives there is no evidence that the introduction of effective competition after privatization increased labor or fuel productivity evidence that privatization increases productivity by itself

privatisation discontent and utility reform in latin america abstract privatisation faces strong and increasingly popular opposition in latin america this paper uses individual data on social attitudes socioeconomic status and demographic information from three waves of latinobarometro surveys 1998 2000 and 2002 in 17 countries to study the role of privatisation of utilities and its distributional impact we find that disagreement with privatisation is most likely when the respondent is on a low to middle income and when it involves a high proportion of public services such as water and electricity this complements recent empirical research that points to distributional concerns in the implementation of privatisation in latin america particularly because of inadequate regulation of utilities

why are wages cyclical in the 1970 s this article investigates cyclicality in real wages between 1969 and 1982 using panel study of income dynamics data there is little evidence that movements in and out of the labor market induced aggregate wage cyclicality during these years however cyclicality in the movement of workers between heterogeneous labor market sectors affected aggregate wage cyclicality while sector location is important sector selectivity is not correlated with wages yet even within sectors cyclicality is present in real wages over this time period and is the result of cyclicality in overall wage levels as well as in the coefficients associated with particular worker characteristics

electricity sector liberalisation and innovation an analysis of the uk s patenting activities abstract liberalisation has had a marked effect on innovative activities in the electricity industry in particular electricity reforms have resulted in a reduction in r d spending in the sector r d and patenting activities are respectively regarded as innovative inputs to and outputs from technological progress the present paper examines the effect of the reforms on patenting activity in the uk electricity sector the results indicate that electricity related patents in non nuclear and renewable technologies have increased in the post liberalisation period we attribute this trend to the increased commercialisation of the sector while this development is positive we argue that a lasting decline in r d will in the longer run reduce technological progress and innovation in the sector in order to maintain the pace of innovation we discuss the need to design a new framework for innovation systems that is commensurate with the functioning and incentive mechanisms of a liberalised sector

determinants of hourly earnings in ecuador the role of labor market regulations ecuadorian labor costs are said to be high because of the existence of many mandated benefits using the 1994 living standards measurement survey we show that the effect of these benefits is actually mitigated by a reduction of base earnings that is of the foundation on which they are paid the reduction is larger in the private than in the public sector and is negligible for unionized workers we also show that in spite of mandated benefits interindustry wage differentials are comparable to those of bolivia a country characterized by flexible labor markets but otherwise similar to ecuador

consumer discrimination and self employment self employment rates and incomes differ significantly by race we show that these differentials arise in markets with consumer discrimination and incomplete information about the price of the good and the race of the seller equilibrium income distributions have two properties mean black incomes are lower than mean white incomes and the returns to ability are lower for black than for white sellers able blacks therefore are less likely to self select into the self employment sector than able whites using the 1980 census data we find that observed racial differences in the self employment income distributions are consistent with the theoretical predictions

wages and unemployment in an urban african labour market this paper argues that urban labor markets in africa exhibit a wage curve similar to those found in the united states britain canada and other developed countries drawing on data from the ivory coast the author finds that urban wages are depressed by higher levels of unemployment this result is robust to changes in model specification and level of aggregation it is consistent with the model of wage determination developed by c shapiro and j stiglitz 1984 and d blanchflower and a oswald 1995 but not with claims that urban wages are invariant to unemployment copyright 1996 by royal economic society

ownership agency and wages an examination of franchising in the fast food industry this paper estimates the difference in compensation between company owned and franchisee owned fast food restaurants the contrast is of interest because contractual arrangements give managers of company owned outlets less of an incentive to monitor and supervise employees estimates based on two data sets suggest that employee compensation is slightly greater at company owned outlets than at franchisee owned outlets the earnings gap is 9 percent for assistant and shift managers and 2 percent for full time crew workers furthermore the tenure earnings profile is steeper at company owned restaurants these findings suggest that monitoring difficulties influence the timing and generosity of compensation

some recent developments in labor economics and their implications for macroeconomics this paper reviews three recent directions of research on labor markets and the macroeconomy models of sectoral shifts and unemployment efficiency wage theories and insider outsider models of wage and employment determination sectoral shifts models show how permanent intersectoral shifts in labor demand and the slow process of labor reallocation across sectors may play an important role in explaining aggregate fluctuations efficiency wage and insider outsider models have in common the property that in equilibrium firms may pay wages in excess of market clearing these models provide potential explanations for persistent involuntary unemployment and segmented labor markets copyright 1988 by ohio state university press

implicit contracts a survey 7mplicit contracts resolve the distribution of uncertainty and utilization of specific human capital between risk averse workers and less risk averse firms incomplete contracts are required to yield involuntary layoffs in contract markets otherwise contracts are efficient and pareto optimal by construction there is a close relation between contract theory and neoclassical labor market theory contracts smooth consumption but increase the volatility of labor supply and labor utilization to demand disturbances because contractural insurance eliminates the income effects of socially diversifiable risks this result is similar to the intertemporal substitution hypothesis however the price mechanism in a contract is substantially different contracts embody a nonlinear two part pricing scheme the lump sum part allocates the income consumption consequences of risks and the marginal pricing part allocates production and labor utilization this implicit pricing mechanism is in all respects flexible though the observed average hourly wage combines both parts and may give the outward appearanceof rigidity furthermore the observed average wage rate in a contract does not reflect marginal conditions necessary for structural econometric estimation indivisibilities appear necessary to account for the split between work sharing and layoffs contracts with private information are also considered in the nonlinear pricing context this abstract was borrowed from another version of this item

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

heterogeneous policies heterogeneous technologies the case of renewable energy this paper investigates empirically the effect of market regulation and renewable energy policies on innovation activity in different renewable energy technologies for the eu countries and the years 1980 to 2007 we built a unique dataset containing information on patent production in eight different technologies proxies of market regulation and technology specific renewable energy policies our main finding is that compared to privatisation and unbundling reducing entry barriers is a more significant driver of renewable energy innovation but that its effect varies across technologies and is stronger in technologies characterised by potential entry of small independent power producers in addition the inducement effect of renewable energy policies is heterogeneous and more pronounced for wind which is the only technology that is mature and has high technological potential finally ratification of the kyoto protocol which determined a more stable and less uncertain policy framework amplifies the inducement effect of both energy policy and market liberalisation

explaining rules based characteristics in u s gaap theories and evidence despite debate on the desirability of rules based standards no studies provide evidence on why accounting standards take on rules based characteristics we identify and test five theories from prior research litigation risk constraining opportunism complexity transaction frequency and age that could explain why some u s accounting standards contain rules based characteristics litigation risk and complexity are most consistently related to cross sectional and time series variation in rules based characteristics we find more limited evidence that frequent transactions age and desires by regulators to constrain opportunistic reporting are related to rules based standards we note however that our findings are necessarily descriptive because standards arise endogenously from market and political forces limiting causal interpretation further it is difficult to perfectly separate rules based characteristics of the standard from both the complexity of the standard and the characteristics of the underlying transaction including the complexity of the transaction

minimum wage effects under endogenous compliance evidence from peru latin american labor markets feature large informal sectors in practice however the simple duality formal informal has many different shades firms tend to comply more with certain legislation than with other recent evidence has suggested that minimum wages have significant effects on the informal sector bell 1997 for mexico gindling and terrell 2004 for costa rica lemos 2004 and fajnzylver 2001 for brazil and maloney and nunez 2004 for colombia further some of this evidence suggests effects throughout a large part of the wage distribution this has been interpreted as evidence of lighthouse or numeraire effects we test this hypothesis using panel data from peru to identify effects throughout the wage distribution although there are some effects on informal sector workers overall results provide little support for numeraire or lighthouse effects labor monthly earnings are affected only at the bottom of the distribution 0 25 0 60 of the minimum wage made up mostly of informal workers and for formal workers earning between the old the new minima negative effects on the probability of retaining employed status after a minimum wage shock are either weak or non significant for wage earners below the minimum wage but significant for formal workers trapped between minima and for both formal and informal earning between 1 2 and 2 times the minimum wage independent workers earning below minimum suffer negative effects on both earnings and employment

electricity costs in irrigated agriculture a case study for an irrigation scheme in spain abstract electricity prices have risen sharply in spain in recent years to the point where they are now among the highest in the eu the scant competition between power utilities changes in the law and the tariff deficit accumulated debt in favour mainly of the electricity firms have driven up the cost of electricity affecting numerous other industries such as irrigated agriculture a sector that has significantly increased its electricity consumption as a result of modernization processes over the past twenty five years we examine these issues through a case study of an irrigation scheme in spain that provides irrigation water and infrastructure to 58 farming communities in north eastern spain and is highly representative of the ebro valley based on the results of direct estimations and simulations of different tariffs we propose the lowering of capacity based tariffs to reduce sector problems and cut energy costs especially for farmers we also raise the possibility of increasing self consumption a complementary measure for many farmers and for medium size firms

from state to private ownership issues from strategic industries abstract this paper investigates the effects of privatization for a panel of 189 firms from strategic industries headquartered in 39 countries and privatized between 1984 and 2002 strategic firms can hardly be compared to manufacturing or competitive industries as they are generally under state monopoly and involve specific issues such as regulation political and institutional constraints we examine the change in ownership and postprivatization means of control by the government and assess whether positive changes in performance obtain in these particular industries that include firms from the financial mining steel telecommunications transportation utilities and oil sectors we document that governments continue to exert influence on former state owned firms after three years by retaining golden shares and or appointing politicians to key positions in the firm our multivariate results reveal a negative effect of state ownership on profitability and operating efficiency which the presence of a sound institutional and political environment moderates
