deposit insurance and external finance i introduction capital markets serve an essential purpose in the growth and development of modern economies they provide for the efficient channeling of funds from savers to investors there are two basic methods for financing capital investment primary issuance of equity or bonds and securing of bank loans looking around the world we see that countries differ substantially in the relative importance of banks and capital markets in providing investment financing equity market capitalization currently ranges from close to zero in countries like austria argentina and greece to nearly two times gross domestic product gdp in the united kingdom south africa and malaysia the importance of bank loan financing is essentially the mirror image of this what accounts for the cross country differences in the importance of banks and capital market financing of investment the purpose of this article is to address this question directly we contend that much of the variation across countries in the depth and breadth of capital markets can be explained by a combination of the existence of deposit insurance and the extent to which a country s banking system is state owned because of the importance of financial intermediation and the difficulties associated with potential bank failures governments in most countries have established a set of institutional structures to ensure the stability of their banking systems primary among these is the creation of deposit insurance by insuring deposits banks liability holders are significantly less likely to request the return of callable deposits reducing the chances of bank runs but at the same time deposit insurance subsidizes bank risk taking activities and allows the payment of lower interest rates to depositors 1 this channels money through banks and away from financial markets direct state bank ownership has a similar impact see barth et al 2001 la porta et al 2000 we present a simple three sector model in which the economy is composed of firms banks and households the firms require operating capital and can obtain it either through equity issuance or from bank loans banks take deposits from households and make loans to firms while households both allocate their wealth and purchase the firms output the model allows us to show how increases in deposit insurance or the percentage of the banking system that is state owned both reduces the size of the capital market and shrinks the amount of bank credit to the private sector and may decrease the number of firms seeking equity financing to examine the predictions of the model we study a data set composed of 49 countries of these 33 currently have explicit deposit insurance and 42 have some state ownership of banks ranging from less than 2 to almost 90 the data confirm the predictions of the model an increase in either state bank ownership or presence of deposit insurance both decreases the size of capital markets and the extent of bank lending for example we would predict that decreasing the percentage of the banking system that is state owned from 36 as it is in italy to zero would increase in the size of the capital market from less than 10 to over 30 of gdp and a raise in the level of bank lending from 57 to close to 90 of gdp our conclusions are in contrast with those in la porta et al 1997 who study the relationship between law and finance la porta et al note the importance of the countries legal system in determining the structure of the financial system in particular they point out that investors provide capital to firms only if they believe they will get their money back for equity holders this means that they must be able to vote out directors and managers who do not pay them for creditors and holders of bonds this means that they must have authority to repossess collateral furthermore these nominal legal rights must be accompanied by confidence that the laws will be enforced

corporate philanthropic disaster response and ownership type evidence from chinese firms response to the sichuan earthquake this article examines whether the charitable giving amount and likelihood of firm response to catastrophic events relate to firms ownership type using a unique dataset of listed firms in china where state ownership is still prevalent based on the data of chinese firms response to the 2008 sichuan earthquake we find that the extent of corporate contributions for state owned firms following this disaster is less than that for private firms state owned firms are also less likely to respond in this disaster compared to private firms the results also reveal that firm size profitability geography cash resource available and leverage affect firms philanthropic disaster response behavior in china

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

is unemployment lower if unions bargain over employment would there be more employment if unions bargained over employment and not only over wages most economists seem to answer yes 1

deregulation shock in product market and unemployment in a dynamic general equilibrium model with endogenous markups and labor market frictions we investigate the effects of increased product market competition unlike most macroeconomic models of search we endogenize the labor supply along the extensive margin we find numerically that a model with endogenous labor force participation decision produces a decline in the unemployment rate which is almost three times larger than that in a model with fixed labor force for a calibration capturing alternatively the european and the us labor markets a deregulation episode which lowers the markup by 3 percentage points results in a fall in the unemployment rate by 0 17 and 0 05 percentage point respectively while the labor share is almost unaffected in the long run the sensitivity analysis reveals that product market deregulation is more effective in countries where product and labor market regulations are high unemployment benefits are small and labor force is more responsive

fiscal consequences of structural reform under constrained monetary policy abstract structural reforms in particular reductions in mark ups in product and labour markets can entail short run output costs unless offset by a demand expansion when monetary policy is constrained and cannot carry out this short run expansion there is a potential role for fiscal policy although this idea has received a lot of attention in the policy debate there has been little formal study of the fiscal consequences of reforms under constrained monetary policy this paper uses a model to quantify the short run fiscal costs and long run fiscal benefits of reforms in order to see to what extent the latter justify the former the fiscal costs and benefits of reforms are both generally found to be small although larger reforms entail larger rises in deficit to gdp in the short run results suggest that reforms in labour markets have little effect on public finances in the long run but their short run costs can be ameliorated if combined with product market reforms

corporate philanthropic giving advertising intensity and industry competition level this article examines whether the likelihood and amount of firm charitable giving in response to catastrophic events are related to firm advertising intensity and whether industry competition level moderates this relationship using data on chinese firms philanthropic response to the 2008 sichuan earthquake we find that firm advertising intensity is positively associated with both the probability and the amount of corporate giving the results also indicate that this positive advertising intensity philanthropic giving relationship is stronger in competitive industries and firms in competitive industries are more likely to donate this study thus provides evidence suggesting that even in the wake of catastrophic events corporate philanthropic giving is strategic

macroeconomic performance and collective bargaining an international perspective this paper critically reviews the research on how collective bargaining systems influence macroeconomic performance in industrialized countries the review considers effects of bargaining level coordination and corporatist institutional arrangements key empirical results turn out to be quite fragile and much of the paper explores issues of measurement and specification that account for the fragility the paper concludes that complementarities between key institutions and between institutions and the economic environment may be more important for macroeconomic performance than the effects of individual institutions and it suggests research strategies

the value of corporate philanthropy during times of crisis the sensegiving effect of employee involvement recent research suggests that philanthropy s value to the firm is largely mediated by contextual factors such as managers assumed motives for charity our article extends this contingency perspective using a sensegiving lens by which external actors interpretations of organizational actions may be influenced by the way in which the organization communicates about those actions we consider how sensegiving features in philanthropy related press releases affect whether investors value those donation decisions for the empirical investigation in this study we analyze abnormal returns to announcements by u s fortune 500 firms documenting their donations to hurricane katrina disaster relief in 2005 we expect that in general donation decisions would be controversial given the uncertainty surrounding the hurricane s economic effects at the time however we also propose that announcements emphasizing employee involvement in the donation send investors positive signals about the firm s ability to bounce back from the disaster s adverse effects we find empirical support for the proposed hypotheses and discuss the implications for theory and practice

sticky prices as coordination failure this paper links the coordination failure and menu cost approaches to the microeconomic foundations of keynesian macroeconomics if a firm s desired price is increasing in others prices then the gain from price adjustment after a nominal shock is greater if others adjust this strategic complementarity leads to multiple equilibria in the degree of rigidity welfare may be much higher in the equilibria with less rigidity thus nominal rigidity arises from a failure to coordinate price changes jel e12 e30 keynesian macroeconomics waned in the 1970 s because economists grew disenchanted with its weak microeconomic foundations the central difficulty was that keynesian models were based on ad hoc rigidities in nominal wages and prices the 1980 s produced two approaches to reviving keynesian theory the menu cost literature n gregory mankiw 1985 george akerlof and janet yellen 1985 seeks to provide rigorous explanations for nominal rigidities these papers argue that small frictions in price setting are enough to produce large nominal rigidities in contrast the coordination failure literature russell cooper and andrew john 1988 abandons nominal rigidities and seeks alternative foundations for keynesian models the central idea is that many economic activities such as production e g john bryant 1983 trade e g peter diamond 1982 and investment e g nobuhiro kiyotaki 1988 exhibit synergism or strategic complementarity one agent s optimal level of activity depends positively on others activity strategic complementarity can lead to multiple equilibria with high activity equilibria superior to low activity equilibria thus an economy may be stuck in an underemployment equilibrium even though a superior equilibrium exists models with nominal rigidities and models with coordination failures are often presented as competing paradigms 1 this paper shows that this view is incorrect we take a step toward unifying the foundations of keynesian economics by showing that the two sets of ideas are highly complementary nominal rigidity arises from a failure to coordinate price changes this failure has the essential features of coordination failures in previous models flexibility in one firm s price increases the incentives for other firms to make their prices flexible this strategic complementarity leads to multiple equilibria in the degree of nominal rigidity equilibria with less rigidity more active price adjustment are often pareto superior to equilibria with more rigidity these results contribute to our understanding both of coordination failure and of nominal rigidity the range of keynesian phenomena explained by coordination failures is greatly expanded previous coordination failure models contain only real variables and thus ascribe no role to monetary policy or other determinants of nominal spending our results suggest that coordination failure is at the root of inefficient nonneutralities of money theories of nominal rigidities gain new empirical and policy im

valuation effect of emotionality in corporate philanthropy despite receiving a great deal of research attention the effect of corporate philanthropy on shareholder value remains inconclusive to address this issue the present paper examines emotionality as an important factor based on which investors infer about the firm s motive as well as the beneficiary s worthiness and react accordingly consistent with attribution theory our event study shows that announcements with more emotional expressions are associated with higher cumulative abnormal stock returns and the effect is stronger when investor attention is greater we further find that the positive interaction effect between emotionality and investor attention is more pronounced for scandal free firms than for firms with corporate social irresponsibility csi the empirical evidence remains consistent under various robustness tests the paper concludes with implications for future research and managerial practices

the transatlantic productivity gap a survey of the main causes abstract during the last 2 decades europe s economy experienced a productivity slowdown whereas the united states us economy exhibited a marked acceleration the result is that since the early 1990s the relative productivity levels between the two regions have continuously diverged leading to a transatlantic productivity gap much of the explanation for this is the strong performance of the us in the so called new economy or knowledge economy and in particular the underinvestment in r d and as a result productivity and innovation has been at the forefront in the european policy agenda however various explanations for the us european union transatlantic productivity gap suggest that the picture is rather more complex than simply the effects on or the result of particular technology driven sectors

can imperfect competition explain the difference between primal and dual productivity measures estimates for u s manufacturing it is well known that under the assumptions of constant returns to scale perfect competition and the absence of factor hoarding primal and dual productivity measures should be highly correlated the apparent lack of correlation is usually attributed to fixed factors of production in this paper i propose an alternative explanation by relaxing the assumption of perfect competition by controlling for the presence of a markup component i demonstrate that both productivity measures are in fact highly correlated for u s manufacturing the analysis also provides an alternative method of estimating a markup of prices over marginal cost that avoids certain difficulties inherent in some existing methods of estimation

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

does entry regulation hinder job creation evidence from the french retail industry are product market and entry regulation key sources of low employment growth in many european countries we investigate this question in the context of the french retail trade industry since 1974 approval by regional zoning boards has been required for the creation or extension of any large retain store in france we exploit a unique database that provides time and region specific variation in boards approval decisions we show that stronger deterrence of entry by the boards increased retailer concentration and slowed down employment growth in france

macroeconomic effects of regulation and deregulation in goods and labor markets product and labor market deregulation reduce and redistribute rents leading economic players to adjust to this new distribution it typically comes with distribution and dynamic effects to study these effects we build a macroeconomic model on two central assumptions monopolistic competition in the goods market which determines the size of rents and bargaining in the labor market which determines the distribution of rents product market regulation determines entry costs and the degree of competition labor market regulation determines the bargaining power of workers we show the effects of deregulation we then use our results to discuss the political economy of deregulation and recent macroeconomic evolutions in europe

interactions of commitment and discretion in monetary and fiscal policies we consider monetary scal interactions when the monetary authority is more conservative than the scal with both policies discretionary 1 nash equilibrium yields lower output and higher price than the ideal points of both authorities 2 of the two leadership possibilities scal leadership is generally better with scal discretion monetary commitment yields the same outcome as discretionary monetary leadership for all realizations of shocks but scal commitment is not similarly negated by monetary discretion second best outcomes require either joint commitment or identical targets for both authorities output socially optimal and price level appropriately conservative or complete separation of tasks jel e61 e63

competition and the capital labor conflict abstract this paper analyzes the distributional effects of changes in the intensity of product market competition the focus is on the interaction between imperfect competition in product markets and bargaining in the labor market the main result is that while a uniform intensification of product market competition increases employment it may cause real wages to fall in the short run as well as in the long run this is especially likely if labor market regulations are favorable to workers therefore product market and labor market regulations tend to reinforce each other politically and compensatory fiscal transfers may be needed in order to enact employment enhancing deregulation policies

labour market implications of eu product market integration eu labour markets effects of greater product market integration european labour markets are in a state of flux due to the changing market situation induced by international integration this process affects wage formation through more fierce product market competition and increased mobility of jobs this development is by some observers taken to enforce labour market flexibility while for others it signals an erosion of social standards and in turn possibly the welfare society since labour is not very mobile in europe the effects of international integration on labour markets are mostly indirect via product market integration we review the channels through which product market integration affects labour markets and perform an empirical analysis of the convergence and interdependencies in wage formation among eu countries we find that integration is changing labour market structures and inducing wage convergences as well as stronger wage interdependencies but it is a gradual process moreover the present study does not support the view that international integration will lead to a race to the bottom and rapidly erode domestic labour markets standards nor that it will relieve politicians of the need to consider labour market reforms to improve labour market performance torben m anderson niels haldrup and jan rose sorensen

theoretical developments in the light of macroeconomic policy and empirical research macroeconomics is surveyed with emphasis on the implications of the new classical and rational expectations critiques for the keynesian paradigm and the role of macro policies at the background are the main macro developments of the 1 970s and 1 980s as well as the specific lessons of recent high chronic inflation processes a synthesis is emerging in which the basic keynesian view of the existence of market and price coordination failures as well as room for pareto improving policy intervention are maintained at the same time the theoretical underpinnings are undergoing substantial change mainly due to a rational expectations reformulation

asymmetric effects of money supply shocks and trend inflation in recent years a number of empirical studies have presented evidence that money supply shocks have asymmetric effects that is unexpected negative changes in the money supply slow the economy more than unexpected positive changes accelerate the economy evidence of asymmetry was documented by cover 1992 for the postwar u s economy and his finding was confirmed by de long and summers 1988 morgan 1993 rhee and rich 1995 and karras 1996a b stimulated by these empirical works several attempts have been made to provide microeconomic foundations for the asymmetric effects of money supply shocks 1 among those theories this paper examines the one that focuses on asymmetric price adjustment and let us call it a sticky price theory money supply shocks will have asymmetric effects on real output if prices are less flexible downward than upward this sticky price theory was proposed by tsiddon 1993 ball and mankiw 1994 and caballero and engel 1992 by employing a menu cost model the above researchers show that positive trend inflation can produce the asymmetric effects of money supply shocks the logic of their theory is the following along with price adjustment costs positive trend infla

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

managerial incentives and product market competition are imperfectly competitive leibenstein 1966 claims that there may be a substantial amount of x inefficiency where x inefficiency measures the degree to which actual profits depart from the maximum of profits that could be obtained if all operations in the firm were carried out at minimal costs he offers empirical evidence from case studies showing that the welfare loss due to organizational slack is of an order of magnitude bigger than the welfare loss due to monopolistic price distortions on imperfectly competitive markets these results support the common presumption that increasing competition reduces organizational and in particular managerial slack however this early literature does not offer a theoretical explanation for the link between competition and managerial incentives in particular it ignores the fact that managerial incentives can be affected by the design of an incentive scheme in this paper i derive the optimal incentive scheme for a manager as a function of the competitiveness of the environment in which his firm operates the basic impact of increased competition is that it reduces the profits of a firm this has two effects in the model first if a firm has high costs then the reduction of profits may be sufficient to render the firm unprofitable so the probability that it has to be liquidated goes up this unambiguously induces the manager of the firm to work harder for a cost reduction in order to avoid liquidation and to keep his job second the reduction in profits may affect

unemployment at risk the policy determinants of labour market exposure to economic shocks this paper examines the vulnerability of labour markets to adverse economic shocks we define labour market exposure as the cumulated amount of excess unemployment generated by a shock before unemployment returns to steady state we use a panel of 19 countries covering the period 1985 2010 to assess the influence of labour market policies on labour market exposure which is also calculated country by country we find that less generous unemployment insurance more active labour market policies or a lower minimum wage imply a trade off between average unemployment and labour market exposure as they help low skilled workers to get out of unemployment at the cost of increased vulnerability to adverse shocks on the other hand reducing the tax wedge is conducive to both lower steady state unemployment and labour market exposure alain de serres and fabrice murtin

the efficiency of firms what difference does competition make in cournot oligopoly the efficiency of a firm relative to others determines its market share this relationship gives an incentive to improve efficiency the incentives are greater in markets where firm behaviour is more competitive components of firm efficiency are identified by frontier production function techniques in 19 uk manufacturing sectors technical change average efficiency of each firm relative to the frontier and the efficiency of each firm relative to its own best practice in each period short run declines in market shares and profits induce the firm to improve efficiency relative to its best practice long run differences in efficiency are correlated with differences in gross investment

beat em or join em export subsidies versus international research joint ventures in oligopolistic markets this paper compares adversarial with cooperative industrial and trade policies in a dynamic oligopoly game in which a home and foreign firm compete in r d and output and because of spillovers each firm benefits from the other s r d when the government can commit to an export subsidy such a policy raises welfare relative to cooperation except when r d is highly effective and spillovers are near complete without commitment however subsidisation may yield welfare levels much lower than cooperation and lower even than free trade though qualifications to the dangers from no commitment are noted

the formation of the european common market and changes in market structure and performance abstract this paper examines the effects of the formation of the common market on changes in seller concentration and price cost margins in the member states using nace 3 digit industry data for west germany france italy belgium and the netherlands the paper first seeks to identify the effect of the removal of intra ec tariffs on changes in national concentration the paper than tests the hypothesis that concentration measured at the ec wide level is becoming a relevant structural variable which affects the national price cost margin

product market reforms labour market institutions and unemployment we analyze the impact of product market competition on unemployment and wages and how this depends on labour market institutions we use differential changes in regulations across oecd countries over the 1980s and 1990s to identify the effects of competition we find that increased product market competition reduces unemployment and that it does so more in countries with labour market institutions that increase worker bargaining power the theoretical intuition is that both firms with market power and unions with bargaining power are constrained in their behaviour by the elasticity of demand in the product market we also find that the effect of increased competition on real wages is beneficial to workers but less so when they have high bargaining power intuitively real wages increase through a drop in the general price level but workers with bargaining power lose out somewhat from a reduction in the rents that they had previously captured

liability of foreignness natural disasters and corporate philanthropy this study examines how philanthropy can mitigate liability of foreignness lof in the aftermath of a national disaster a major disaster restructures the social landscape creating an avenue for corporate contributions to play a role in recovery and relief efforts this social restructuring offers a valuable opportunity for multinational enterprises mnes to establish strong local ties in turn mne contributions at such times have a stronger impact on their local acceptance thus mnes can use these events to strengthen their position in the community and mitigate lof using the context of a national disaster in india i test these arguments with a sample of 190 mnes and 660 domestic firms i found that in the aftermath of the disaster the increase in mne contributions was much larger and less strongly tied to promotional activities than the increase in contributions from domestic firms and this difference persisted over time moreover the performance implication of post disaster philanthropy was stronger for mnes than for domestic firms these findings suggest that philanthropy plays a more strategic role for mnes in the aftermath of a disaster and it has a pronounced effect on mitigating lof

what determines aggregate returns to scale abstract this paper develops a unified framework that incorporates four features important in existing models with increasing returns fixed costs decreasing marginal costs product variety and market power when fixed costs are not allowed to vary and profits are imposed to be zero in every period only the degree of returns to variety determines the degree of aggregate increasing returns to scale when fixed costs respond to changes in aggregate activity or the zero profit condition does not hold in the short run aggregate returns depend not only on product variety but also on diminishing marginal costs or market power the degree of market power however does not affect input prices which are critical to determine the uniqueness of equilibrium

social responsiveness profitability and catastrophic events evidence on the corporate philanthropic response to 9 11 in this study we seek to determine whether catastrophic events lead to corporate charitable giving unrelated to levels of firm profitability we examine the issue relative to the corporate philanthropic response to the 9 11 terrorist attacks of 2001 based on a sample of 489 fortune 500 companies we find that differences in the extent of corporate contributions following 9 11 are positively and significantly associated with differences in firms profitability further while the degree of connection to the catastrophic event led to higher levels of giving in comparison to the contributions of less connected firms differences in the extent of philanthropy are still related to short term profitability for the more connected firms the study thus provides evidence suggesting that even in the wake of catastrophic events corporate philanthropic giving is constrained by economic concerns

revisiting the okun relationship our article revisits the okun relationship between observed unemployment rates and output gaps we include in the relationship the effect of labour market institutions as well as age and gender effects our empirical analysis is based on 20 oecd countries over the period 1985 2013 we find that the share of temporary workers which includes a high and rising share of young workers played a crucial role in explaining changes in the okun coefficient the impact of the output gap on the unemployment rate over time the okun coefficient is not only different for young prime age and older workers but also it decreases with age from a policy perspective it follows that an increase in economic growth will not only have the desired outcome of reducing the overall unemployment rate but it will also have the distributional effect of lowering youth unemployment

price rigidities and market structure conventional wisdom has it that a large part of the explanation of keynesian unemployment is the observed rigidities of wages and prices what has been lacking however is a satisfactory theory or conjunction of theories which explains how wages and prices can be at non market clearing levels the objective of this paper is to sketch out several alternative theoretical explanations of this phenomenon each in contrast with keynesian theory is consistent with the observation that as the economy goes into a recession real product wages do not increase and may in fact decrease all of the theories assume rational profit maximizing firms and all entail some important departure from the standard competitive paradigm the first three explanations represent minor adaptations of standard models

increasing returns and the foundations of unemployment theory current approaches to macroeconomic theory divide roughly into two basic schools of thought one approach typically associated with rational expectations views the economy as basically at or near walrasian market clearing equilibrium in which case it becomes very difficult to explain away convincingly the undeniable persistence at times of involuntary unemployment another approach views the underemployed economy as being in a state of temporary fixed price disequilibrium in which case aside from having to repress suspicions that the essence of effective demand failure might not have to do with prices fixed at wrong values there is a lot of rationalising to be done about why profitable adjustments are so slow this paper argues that something like an internally consistent theory of steady state involuntary unemployment is possible and even plausible the cornerstone of this third approach is increasing returns to scale which blocks unemployed agents from breaking out of a low level equilibrium trap unless there is overall coordination or stimulation a simple model is presented which contains the basic ideas

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

employment effects of product and labour market reforms are there synergies this article investigates the effect of product market liberalisation on employment allowing for interactions between policies and institutions in product and labour markets using panel data for oecd countries over the period 1980 2002 we present evidence that product market deregulation is more effective at the margin when labour market regulation is high the data also suggest that product market liberalisation may promote employment enhancing labour market reforms

corporate philanthropy and stock price crash risk evidence from china how to mitigate stock price crash risk has become a focus in the theoretical and practical fields building on the work of kim et al j bank finance 43 1 13 2014b this paper investigates the relation between corporate philanthropy and crash risk under the unique chinese institutional background the results show that both state ownership and the 2005 split share reform attenuate the mitigating effect of corporate philanthropy on crash risk specifically the negative relation between corporate philanthropy and crash risk is less pronounced for state owned enterprises than for non state owned enterprises and it is also less pronounced after firms accomplish the split share reform further this effect is more pronounced for firms with greater financial risks and poorer performance our paper contributes to the growing literature on the determinants of stock price crash risk and the economic consequences of corporate philanthropy it also offers useful guidance to firms that are seeking to reduce stock price crash risk in emerging markets

wage setting and the tax system theory and evidence for the united kingdom abstract this paper analyses the effects of a non linear tax system on wage bargaining the main conclusions are an increase in the marginal income or payroll tax rate reduces the pre tax wage in the isoelastic case an increase in the average tax rate increases the pre tax wage by more than the tax increase and a measure of the progressivity of the tax system residual income progression is a sufficient measure of the effect of the tax system on wage pressure empirical evidence is presented to support these propositions and the predictions of the model regarding the effect of recent changes to the u k tax system on the distribution of earnings discussed

taxation unemployment and growth dynamic welfare effects of green policies abstract this paper analyzes the effects of environmental tax reforms on a small open economy the labor market is characterized by union wage setting the carbon tax acts as an implicit tariff which gives rise to terms of trade gains the terms of trade effect together with the union wage setting leads to a positive relationship between the capital labor ratio and net foreign wealth in the short run the disinvestments in real and financial capital give temporary room for higher consumption and instantaneous utility the long run effect on instantaneous utility is more uncertain a strong double dividend may exist

donate money but whose an empirical study of ultimate control rights agency problems and corporate philanthropy in china using empirical evidence gathered from chinese listed companies this article explores the relationship between micro governance mechanisms and corporate philanthropy from a corporate governance perspective in china s emerging market ultimate controlling shareholders of state owned enterprises soes are reluctant to donate their assets or resources to charitable organizations in private enterprises pes marked by more deviation in voting and cash flow rights such donations tend to be more likely however the ultimate controllers in pes refuse to donate assets or resources they control or own which implies that corporate philanthropy by pes comes at the cost of others through assets or resources owned by minority shareholders even after devastating natural disasters such as the 2008 wenchuan earthquake the controlling shareholders continue to express reluctance to donate any assets they control despite widespread evidence that corporate philanthropy boosts corporate growth and profitability these ultimate controllers indicate no intention to donate their own money as a means to improve corporate performance

patent protection southern innovation and welfare in a north south trade model in a north south trade model we analyse the implications of southern patent protection on southern innovation profits and welfare southern patent protection may make the northern firm worse off and the southern firm better off by increasing the southern firm s incentive for innovation and affecting the nature of competition in the world market the impact of southern patent protection on a country s welfare and on world welfare depends on the cost of southern innovation and the degree of product substitutability we provide important insights into the outcomes of international negotiations regarding patent enforcement in the southern countries
