fiscal paradise foreign tax havens and american business the tax haven affiliates of american corporations account for more than 20 percent of u s foreign direct investment and nearly a third of the foreign profits of u s firms american companies report extraordinarily high profit rates on their tax haven investments in 1982 this behavior implies that the revenue maximizing tax rate for a typical haven is around 5 8 percent american and foreign investment in tax havens has an uncertain effect on u s tax revenue but since low tax rates encourage american companies to shift profits out of high tax foreign countries it is possible that low foreign tax rates ultimately enhance u s tax collections

earnings shocks and tax motivated income shifting evidence from european multinationals this paper presents a new approach to estimating the existence and magnitude of tax motivated income shifting within multinational corporations existing studies of income shifting use changes in corporate tax rates as a source of identification in contrast this paper exploits exogenous earnings shocks at the parent firm and investigates how these shocks propagate across low tax and high tax multinational subsidiaries this approach is implemented using a large panel of european multinational affiliates over the period 1995 2005 the central result is that parents positive earnings shocks are associated with a significantly positive increase in pretax profits at low tax affiliates relative to the effect on the pretax profits of high tax affiliates the result is robust to controlling for various other differences between low tax and high tax affiliates and for country pair year fixed effects additional tests suggest that the estimated effect is attributable primarily to the strategic use of debt across affiliates the magnitude of income shifting estimated using this approach is substantial but somewhat smaller than that found in the previous literature

changes in the value relevance of earnings and book values over the past forty years this paper investigates systematic changes in the value relevance of earnings and book values over time we report three primary findings first contrary to claims in the professional literature the combined value relevance of earnings and book values has not declined over the past forty years and in fact appears to have increased slightly second while the incremental value relevance of bottom line earnings has declined it has been replaced by increasing value relevance of book values finally much of the shift in value relevance fiom earnings to book values can be explained by the increasing frequency and magnitude of one time items the increasing frequency of negative earnings and changes in average firm size and intangible intensity across time

dematerialization decoupling and productivity change abstract the prospects for long term sustainability depend on whether and how much we can absolutely decouple economic output from total energy and material throughput while relative decoupling has occurred that is resource use has grown less quickly than the economy absolute decoupling has not raising the question whether it is possible this paper proposes a novel explanation for why decoupling has not happened historically drawing on a recent theory of cost share induced productivity change and an extension of post keynesian pricing theory to natural resources cost share induced productivity change and pricing behavior set up two halves of a dynamic which we explore from a post keynesian perspective in this dynamic resource costs as a share of gdp move toward a stable level at which the growth rate of resource productivity is typically less than the growth rate of gdp this provides a parsimonious explanation of the prevalence of relative over absolute decoupling the paper then presents some illustrative applications of the theory

price dynamics and production lags this paper provides a new explanation of why inflation is sluggish in response to aggregate demand shocks and why aggregate output changes as result of such shocks we argue that these phenomena are related to lags between inputs and outputs in the production process production lags for short the broad intuition is that production activities in a modern economy are interconnected through complex input output relations with production lags within individual firms and that it takes considerable time for cost and price changes to penetrate the entire input output system our analysis provides a rationale for a prolonged inverse relation between inflation and unemployment the paper suggests that the interaction of inflation persistence and unemployment persistence may offer a possible explanation of high and prolonged european unemployment this abstract was borrowed from another version of this item

climate change financial stability and monetary policy using a stock flow fund ecological macroeconomic model we analyse i the effects of climate change on financial stability and ii the financial and global warming implications of a green qe programme emphasis is placed on the impact of climate change damages on the price of financial assets and the financial position of firms and banks the model is estimated and calibrated using global data and simulations are conducted for the period 2015 2115 four key results arise first by destroying the capital of firms and reducing their profitability climate change is likely to gradually deteriorate the liquidity of firms leading to a higher rate of default that could harm both the financial and the non financial corporate sector second climate change damages can lead to a portfolio reallocation that can cause a gradual decline in the price of corporate bonds third financial instability might adversely affect credit expansion and the investment in green capital with adverse feedback effects on climate change fourth the implementation of a green qe programme can reduce climate induced financial instability and restrict global warming the effectiveness of this programme depends positively on the responsiveness of green investment to changes in bond yields

internationalization in the information age a new era for places firms and international business networks the new techno economic paradigm of the information age has brought about new structures and processes in international business ib in this article we examine the changing nature of the competitive advantages of places the competitive advantages and strategies of firms and the governance structure of ib networks in what has also been called the third industrial revolution these three areas of change in ib activities can be mapped respectively to the location l ownership o and internalization i advantages of the eclectic paradigm we interpret these oli factors as dynamic constructs in order to depict analytically the shifts in the ib environment and their implications for ib

the effect of taxes on investment and income shifting to puerto rico the income of puerto rican affiliates of u s corporations is essentially untaxed by either puerto rico or the united states this lowers the tax penalty on investment there and also makes it attractive to shift reported taxable income from the u s parent corporation to the puerto rican affiliate this paper investigates these two interrelated impacts of taxation by developing a structural econometric model of the joint decisions regarding investment and income shifting and estimating the model using firm level data on the activity u s corporations in puerto rico the results suggest that the income shifting advantages are the predominant reason for u s investment in puerto rico

research in accounting for income taxes abstract this paper comprehensively reviews the accounting for income taxes afit literature we begin by identifying four distinctive aspects of afit and briefly covering the rules surrounding afit we then review the existing studies in detail and offer suggestions for future research we emphasize the research questions that have been addressed most of which relate to whether the tax accounts are used to manage earnings and whether the tax accounts are priced by equity market participants we also highlight areas that have not received much research attention and that warrant future analysis

on real and sticky price theories of the business cycle after presenting some facts about the growth of government in western industrialized countries possible causes of this development are analyzed from a public choice perspective next some empirically tested theories which seek to explain this growth are discussed finally possible consequences for efficiency and individual liberty are examined it is shown that both the number and size of interest groups age of democracy as stated by mancur olson 1982 and the increasing share of government expenditure in gdp seem to exert a negative influence on the growth rate of gdp copyright 1986 by ohio state university press

the incidence of nominal and real wage rigidities in great britain 1978 98 this paper analyzes the extent of rigidities in wage setting in great britain over the 1980s and 1990s our estimation strategy which generalizes the work of altonji and devereux 2000 models the notional wage growth distribution the distribution of nominal wage growth that would occur in the absence of rigidities in pay while allowing for the presence of measurement error in the data the model then allows for the possibility that the nominal wage growth of a fraction of the workforce may be subject to a nominal or real downward rigidity our model suggests that real rigidities in wage setting are more prevalent than nominal rigidities although the incidence of these real wage rigidities has fallen gradually over time if firms cannot cut real wages in response to negative demand shocks they may resort to laying off workers our results support this microfoundation of the wage unemployment phillips curve workers who are more likely to be protected from wage cuts are also more likely to lose their jobs

understanding real business cycles he 1 960s were a time of great optimism for macroeconomists many economists viewed the business cycle as dead the keynesian model was the reigning paradigm and it provided all the necessary instructions for manipulating the levers of monetary and fiscal policy to control aggregate demand inflation occurred if aggregate demand was stimulated excessively and unemployment arose if demand was insufficient the only dilemma faced by policymakers was determining the most desirable location along this inflation unemployment tradeoff or phillips curve the remaining intellectual challenge was to establish coherent microeconomic foundations for the aggregate behavioral relations posited by the keynesian framework but this was broadly regarded as a detail that should not deter policymakers in their efforts to stabilize the economy the return of the business cycle in the 1970s after almost a decade of economic expansion and the accompanying high rates of inflation came as a rude awakening for many economists it became increasingly apparent that the basic keynesian framework was not the appropriate vehicle for understanding what happens during a business cycle nor did it seem capable of providing the empirically correct answers to questions involving changes in the economic environment or changes in monetary or fiscal policy the view that keynesian economics was an empirical success even if it lacked sound theoretical foundations could no longer be taken seriously the essential flaw in the keynesian interpretation of macroeconomic phenomenon was the absence of a consistent foundation based on the choice theoretic framework of microeconomics two important papers one by milton friedman 1968 and the other by robert lucas 1976 forcefully demonstrated examples of

are prices too sticky nominal price rigidity has a negative externality rigidity in one firm s price increases the variability of aggregate real spending which harms all firms this paper investigates whether this externality is large which would imply that stabilization policy can be highly beneficial even if the costs of making prices flexible are small there are three conclusions first both the private cost of price rigidity and the externality are second order in the size of fluctuations second the externality can nonetheless be arbitrarily large third in a simple model the externality is small for plausible parameter values

the economics of technical change this paper reviews the recent rapidly growing literature on technical change in the economy it concentrates on innovations and their diffusion at firm and industry level since this was the area designated as relatively weak in earlier literature surveys the review argues that the extensive empirical evidence and theoretical analysis now available presents a basic challenge to neoclassical theory after indicating some weaknesses in the neo schumpeterian literature the paper concludes by advocating an experiment with a new form of assessment by neighboring disciplines to economics itself which would take full account of the fundamental issues at stake in this modern methodenstreit c 1994 academic press inc copyright 1994 by oxford university press

recent developments in macroeconomics underlying the existence of macroeconomics as a separate field of study are the phenomena of economy wide fluctuations of output and prices and sometimes persistent high levels of unemployment two basic views of macroeconomic behavior have persisted even as conceptual innovati ons and the application of more powerful analytic and empirical techn iques have brought significant changes in understanding of the macroe conomy copyright 1988 by royal economic society

why u s wage and employment behavior differs from that in britain and japan if a poll were to be conducted among american academic economists to select the most mystifying economic phenomenon of our time surely the sticky nominal wage rate would emerge at or near the top of the list the slow and partial response of the nominal wage rate to changes in aggregate nominal spending has been a central postulate of macroeconomic theory for the past 45 years from keynes general theory down to the standard postwar textbook keynesian paradigm to the more modern fixed wage price models of robert barro and herschel grossman i976 and edmond malinvaud i977 unwilling passively to accept nominal wage rigidity as an unexplained assumption many labour market theorists have followed the lead of costas azariadis i975 and martin baily i974 in building models to explain rigid wages and layoff unemployment as the rational outcome of a profit maximising calculus as i pointed out in an early critique of the azariadis baily model i976a their assumptions cannot explain cycles in employment but rather why workers would want fixed incomes i e a fixed wage rate and fixed employment soon thereafter barro i977 went one step further and argued that contract theory is a facade which cannot explain why workers would choose a rigid wage and variable employment in preference to the classical equilibrium quantity of employment that equates the marginal product of labour with the marginal value of time now an examination of the evidence has led me to the realisation that rigid wages cannot provide the underpinnings for a universally valid theory of the business cycle simply because wages are not universally rigid i document below with postwar quarterly data that the share of fluctuations in the manufacturing wage bill taking the form of nominal wage changes as compared to changes in hours worked is five to ten times greater in britain and japan than in

wages and employment in a segmented labor market this paper analyzes the impact of business cycle fluctuations on a labor market segmented into a unionized primary sector and a competitive secondary sector either permanent or temporary changes in real aggregate demand are shown to widen the intersectoral wage differential in recession and under reasonable specifications of key parameters to cause greater fluctuations of primary sector employment than secondary sector employment this pattern agrees with the stylized facts of the u s economy

how stable are corporate capital structures leverage cross sections more than a few years apart differ markedly with similarities evaporating as the time between them lengthens many firms have high and low leverage at different times but few keep debt to assets ratios consistently above 0 500 capital structure stability is the exception not the rule occurs primarily at low leverage and is virtually always temporary with many firms abandoning low leverage during the post war boom industry median leverage varies widely over time target leverage models that place little or no weight on maintaining a particular ratio do a good job replicating the substantial instability of the actual leverage cross section

labor unions and tax aggressiveness abstract we examine the impact of unionization on firms tax aggressiveness we find a negative association between firms tax aggressiveness and union power and a decrease in tax aggressiveness after labor union election wins this relation is consistent with labor unions influencing managers in one or both of two ways 1 constraining managers ability to invest in tax aggressiveness through increased monitoring or 2 decreasing returns to tax aggressiveness that arise from unions rent seeking behavior we also find preliminary evidence that the market expects these reductions around union elections and discounts firms that likely add shareholder value via aggressive tax strategies

remaining puzzles and neglected issues in macroeconomics this paper analyses the chain of transmission mechanisms of economic policy actions to financial markets output and employment and finally unemployment in an attempt to identify remaining puzzles and neglected issues in macroeconomics the paper emphasizes the consequences of fiscal and monetary policy actions on real variables including real interest rates and real exchange rates an attempt is made to explain why product demand shocks often tend to have faster effects on output and employment than on prices the paper also discusses why demand induced increases in output and employment are not systematically connected with a reduction in the product wage rate the paper ends with a discussion of various supply side considerations in macroeconomics

the double bubble at the turn of the century technological roots and structural implications this paper argues that the two boom and bust episodes of the turn of the century the internet mania and crash of the 1990s and the easy liquidity boom and bust of the 2000s are two distinct components of a single structural phenomenon they are essentially the equivalent of 1929 developed in two stages one centred on technological innovation the other on financial innovation hence the frequent references to that crash to the 1930s and to bretton woods are not simple journalistic metaphors for interpreting the credit crunch and its solution but rather the intuitive recognition of a fundamental similarity between those events and the current ones the paper holds that such major boom and bust episodes are endogenous to the way in which the market economy evolves and assimilates successive technological revolutions it will discuss why it occurred in two bubbles on this occasion it examines the differences and continuities between the two episodes and presents an interpretation of their nature and consequences

are declining effective tax rates indicative of tax avoidance insight from effective tax rate reconciliations abstract effective tax rates etrs are often used to compare tax avoidance across firms and time using firms detailed tax footnote data we find that the effect of valuation allowances va related to prior period losses biases gaap etrs this downward bias explains almost all of the downward trend in domestic firms etrs over the last 20 years we also find that vas explain cross sectional differences in etrs for both domestic and multinational firms we show this bias extends to cash etrs and the henry and sansing 2018 tax avoidance measure we develop a methodology for substantially reducing the bias in both time series and cross sectional analyses of cash and gaap etrs overall our results suggest firms loss histories and gaap rules influence inferences from tax avoidance proxies

menu costs and the neutrality of money a model of endogenous price adjustment under money growth is presented firms follow s s pricing policies and price revisions are imperfectly synchronized in the aggregate price stickiness disappears and money is neutral the connection between firm price adjustment and relative price variability in the presence of monetary growth is also investigated the results contrast with those obtained in models with exogenous fixed timing of price adjustment

predetermined wages and prices and the impact of expansionary government policy this paper characterizes the monetary equilibria of an economy with commodity and labour contracts if government policy is not too variable there may exist an equilibrium with predetermined wages and prices in this equilibrium observed changes in the money supply to finance government purchases have persistent real effects the paper also provides theoretical support for an inverse relationship between the degree of indexation in contracts and the persistence of policy effects

a near rational model of the business cycle with wage and price inertia this paper presents a model in which insignificantly suboptimal behavior causes aggregate demand shocks to have significant real effects the individual loss to agents with inertial price wage behavior is second order in terms of the parameter describing the shock while the effect on real economic variables is first order thus significant changes in business activity can be generated by anticipated money supply changes provided that some agents are willing to engage in nonmaximizing behavior which results in small losses

the wage price spiral this paper rehabilitates the old wage price spiral it shows that after an increase in aggregate demand the process of adjustment of nominal prices and nominal wages results from attempts by workers to maintain or increase their real wage and by firms to maintain or increase their markups of prices over wages under continuous price and wage setting the process of adjustment would be instantaneous under staggering of price and wage decisions the adjustment takes time the more inflexible real wages and markups are to shifts in demand the higher is the degree of price level inertia and the longer lasting are the effects of aggregate demand on output

exploring the role delaware plays as a domestic tax haven abstract we examine whether delaware is a domestic tax haven we find that taxes play an economically important role in determining whether u s firms locate subsidiaries in delaware and that a delaware based state tax avoidance strategy lowers state effective tax rates by between 0 7 and 1 1 percentage points on average the tax savings represent a 15 24 decrease in the state income tax burden and translate to an increase in net income of 1 04 1 47 however we find that the tax benefits of delaware tax strategies are diminishing over time in response to initiatives by state governments to limit multistate tax avoidance

the history of the phillips curve consensus and bifurcation while the early history of the phillips curve up to 1975 is well known less well understood is the post 1975 fork in the road the left fork developed a theory of policy responses to supply shocks in the context of price stickiness in the non shocked sector its econometric implementation interacts shocks with backward looking inertia the right fork approach emphasizes forward looking expectations that can jump in response to anticipated policy changes the left fork approach is better suited to explaining the postwar us inflation process while the right fork approach is essential for understanding behaviour in economies with unstable macroeconomic environments the history of the phillips curve pc has evolved in two phases before and after 1975 with a widespread consensus about the pre 1975 evolution which is well understood bifurcation begins in 1975 when the pc literature split down two forks of the road with little communication or interaction between the two forks the major contribution of this paper and hence the source of bifurcation in its subtitle is to examine contrast and test the contributions of the two post 1975 forks the pre 1975 history is straightforward and is covered in section i the initial discovery of the negative inflation unemployment relation by phillips popularized by samuelson and solow was followed by a brief period in which policy makers assumed that they could exploit the trade off to reduce unemployment at a small cost of additional inflation then the natural rate revolution of friedman phelps and lucas overturned the policy exploitable trade off in favour of long run monetary neutrality those who had implemented the econometric version of the trade off pc in the 1960s reeled in disbelief when sargent demonstrated the logical failure of their test of neutrality and finally were condemned to the wreckage of keynesian economics by lucas and sargent following the twist of the inflation unemployment correlation from negative in the 1960s to positive in the 1970s the architects of neutrality and the opponents of the keynesian trade off emerged triumphant with two major caveats that their own models based on information barriers were unconvincing and that their core result that business cycles were driven by monetary or price surprises floundered without supporting evidence after 1975 the evolution of the pc literature split in two directions each of which has largely failed to recognize the other s contributions section ii reviews the left fork of the road the revival of the pc trade off in a coherent and integrated dynamic aggregate supply and demand framework that emerged in the late 1970s in econometric tests in theoretical contributions and in intermediate macro textbooks this approach which i have called mainstream is resolutely keynesian because the inflation rate is dominated by persistence and inertia in the form of long lags on past inflation an important difference between the mainstream approach and other post 1975 developments is that the role of past inflation is not limited to the formation of expectations but also includes a pure persistence effect due to fixed duration wage and price contracts and lags between

sticky prices new evidence from retail catalogs this paper presents new results on the size frequency and synchronization of price changes for twelve selected retail goods over the past 35 years three basic facts about the data are uncovered first nominal prices are typically fixed for more than one year although the time between changes is very irregular second prices change more often during periods of high overall inflation third when prices do change the sizes of the changes are widely dispersed both large and small changes occur for the same item and the sizes of these changes do not closely depend on overall inflation

integrating finance into the multi level perspective technology niche finance regime interactions and financial policy interventions abstract any major socio technical transition requires a fundamental re direction of financial capital from incumbent to new technologies and practices while the transitions literature conceptually covers financial markets the role of finance is marginalized and has scarcely been analysed empirically to address this gap here we build on the multi level perspective mlp which considers financial markets as part of the existing regime we argue that the role of finance is highly relevant for the niche regime interaction redirecting finance towards new niche technologies requires that either the niche is fit for and conforms to the financial regime s expectations or the financial regime is stretched and transformed in order to accept and finance niche technologies based on 56 interviews we identify factors that determine interactions between the financial regime and technology niches these include acceptable risk and transaction size an abundance of knowledge and heuristics in both the regime and niche and an extensive existing industry network we further analyse how state investment bank sib interventions in germany the uk and australia aimed to mobilise private finance into low carbon project development affect the interaction between the technology niche and financial regime i e whether they resulted in fitting and conforming the technological niche for the financial regime or stretching and transforming the financial regime our results point to several important effects of sib interventions with most effects fitting the niche to the regime however we also detect effects that stretch and transform the financial regime through evolutionary processes importantly some effects occur as a consequence of the primary effects based on our findings we discuss policy implications on how to accelerate transitions through policies aiming at finance as well as theoretical insights gained through our analysis

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

nominal rigidities without literal menu costs evidence from e commerce abstract using price data from online book retailers amazon com and barnes and noble com we show that nominal rigidities persist in an environment that is free from literal menu costs menu costs therefore are not the prime reason for nominal rigidities

what marshall didn t know on the twentieth century s contributions to economics some of this century s many valuable contributions to economics like macroeconomics econometrics and game theory are widely recognized however arguably equally important is the enhanced role of empirical study permitted by more abundant data and improved methods also insufficiently recognized are the increased rigor and use of applied economics in public finance regulation corporation finance etc employing abstract theory and sophisticated data analysis the striking contrast with earlier intuitively based applied economics and empirical study is illustrated comparison with marshall s principles also indicates that except for macroeconomics remarkably little space in today s texts deals with some of the rich contributions of this century what has twentieth century economics accomplished a great deal as will be shown here but the discussion needs an illuminating starting point in 1946 after arriving at the london school of economics as an entering graduate student 1 i soon found that in

real business cycles a new keynesian perspective the debate over the source and propagation of economic fluctuations rages as fiercely today as it did 50 years ago in the aftermath of keynes s the general theory and in the midst of the great depression today as then there are two schools of thought the classical school emphasizes the optimization of private economic actors the adjustment of relative prices to equate supply and demand and the efficiency of unfettered markets the keynesian school believes that understanding economic fluctuations requires not just studying the intricacies of general equilibrium but also appreciating the possibility of market failure on a grand scale

keeping the keynesian faith this wide ranging discussion takes in the development of macroeconomics and the influence of ideas and events on that development the nature and causes of the great depression keynesianism lessons from the high inflation period of the 1970s the role of macroeconomic policy and the idea of the new economy

technological revolutions and techno economic paradigms this paper locates the notion of technological revolutions in the neo schumpeterian effort to understand innovation and to identify the regularities continuities and discontinuities in the process of innovation it looks at the micro and meso foundations of the patterns observed in the evolution of technical change and at the interrelations with the context that shape the rhythm and direction of innovation on this basis it defines technological revolutions examines their structure and the role that they play in rejuvenating the whole economy through the application of the accompanying techno economic paradigm this over arching meta paradigm or shared best practice common sense is in turn defined and analysed in its components and its impact including its influence on institutional and social change

the magnitude of menu costs direct evidence from large u s supermarket chains we use store level data to document the exact process of changing prices and to directly measure menu costs at five multistore supermarket chains we show that changing prices in these establishments is a complex process requiring dozens of steps and a nontrivial amount of resources the menu costs average 105 887 year per store comprising 0 70 percent of revenues 35 2 percent of net margins and 0 52 price change these menu costs may be forming a barrier to price changes specifically 1 a supermarket chain facing higher menu costs due to item pricing laws that require a separate price tag on each item changes prices two and one half times less frequently than the other four chains 2 within this chain the prices of products exempt from the law are changed over three times more frequently than the products subject to the law in principle fixed costs of changing prices can be observed and measured in practice such costs take disparate forms in different firms and we have no data on their magnitude so the theory can be tested at best indirectly at worst not at all alan blinder 1991 p 90

the real debt resistance hypothesis and persistence of unemployment in the oecd countries according to friedman 1968 p 10 unemployment above the natural rate should sooner or later lead to deflation and an accelerating deflation at that as table 1 shows until the mid 1980s the course of movement of the rate of unemployment and inflation in the oecd countries is in conformity with this hypothesis however since the mid 1980s and in spite of continuing high unemployment the rate of inflation remained at a significantly positive level there is certainly not evidence of accelerated deflation as predicted by friedman the most popular explanation offered is the possibility of presence of the hysteretic tendencies in the nairu three famous models in this respect are the insider outsider hypothesis of blanchard and summers 1986 the capacity constraint hypothesis of sneessens and dreze 1986 and the declining search effectiveness long term unemployment hypothesis of layard nickell and jackman 1991 all these explanations rely on the real wage rigidity as table 1 shows however the rigidity of real wages seems to be more due to the downward rigidity of the rate of growth of nominal wages and prices for example the average weekly earnings of the production workers in the us manufacturing sector has steadily increased since 1946 1 thus contrary to the dominant view in the new keynesian school see gordon 1990 what needs to be explained is the long term downward rigidity of nominal wages

a discussion of belgian unemployment combining traditional concepts and disequilibrium econometrics with a gdp of less than 100 billion and exports of more than 60 billion belgium comes perhaps closer than any other country to being a small open economy consequently trends in world trade and export performance have a major impact on domestic activity whereas the impact of domestic fiscal policy is damped by import leakages table 1 presents a few figures confirming these observations

differences in the rates of return to r d for european and us young leading r d firms this paper examines the sources of europe s lagging business r d performance relative to the us particularly the role played by missing young leading innovators in high technology intensive sectors in europe it investigates through econometric analysis differences in the rates of return to r d of european and us large r d firms it finds that while in the us young firms succeed in realizing significantly higher rates of return to r d as compared to their older counterparts including in high tech sectors european firms fail to generate significant rates of return even if they are yollies and even if they are in high tech sectors these findings can at least partly explain why europe has less r d intensive young leading innovators in high technology intensive sectors

origins and pathways of innovation in the third industrial revolution this study examines the factors that shaped the long term evolution of the ict industry in sweden 1950 2013 using a new historical microdatabase on actual innovation output the driving forces and technological interdependencies in the third industrial revolution are chronicled the results of this study support some stylized facts about technological interdependencies in general purpose technologies a closely knitted set of industries have provided positive and negative driving forces for the development of ict innovations the historical evolution of gpts can in this perspective be described as a sequence of development blocks

the national system of innovation in historical perspective contrary to some recent work on so called globalisation this paper argues that national and regional systems of innovation remain an essential domain of economic analysis their importance derives from the networks of relationships which are necessary for any firm to innovate whilst external international connections are certainly of growing importance the influence of the national education system industrial relations technical and scientific institutions government policies cul tural traditions and many other national institutions is fundamental the historical examples of germany japan and the former ussr illustrate this point as well as the more recent contrast between east asian and latin american countries introduction the national system of friedrich list according to this author s recollections the first person to use the expression national system of innovation was bengt ake lundvall and he is also the editor of a highly original and thought provoking book 1992 on this subject however as he and his colleagues would be the first to agree and as lundvall himself points out the idea actually goes back at least to friedrich list s conception of the national system of political economy 1841 which might just as well have been called the national system of innovation the main concern of list was with the problem of germany overtaking england and for underdeveloped countries as germany then was in relation to england he advocated not only protection of infant industries but a broad range of policies designed to accelerate or to make possible industrialisation and economic growth most of these policies were concerned with learning about new technology and applying it the racialist and colonialist overtones of the book were in strong contrast to the inter nationalist cosmopolitan approach of the classical free trade economists and list s belief that holland and denmark should join the german bund and acquire german nationality because of their descent and whole character reads somewhat strangely in the european community of today nevertheless despite these unattractive features of his outlook he clearly anticipated many contemporary theories after reviewing the changing ideas of economists about development in the years since the second world war the world bank 1991 concludes that it is intangible investment in knowledge accumulation which is decisive rather than physical capital investment as was at one time believed pages 33 35 the report cites the new growth theory

relative wages efficiency wages and keynesian unemployment while modern economic theorists have produced a variety of explanations for the failure of wages to fall in the face of unemployment keynes emphasis on relative wages has not been reflected in most contemporary discussions this short paper suggests that relative wage theories in which workers productivity depends primarily on their relative wage provide the best available apparatus for understanding actual unemployment and its fluctuations such theories are very closely related to the efficiency wage theories that have received widespread attention in recent years this abstract was borrowed from another version of this item

a test of dual labor market theory despite substantial differences in their views of the appropriate policy response to the existence of poverty neither the proponents of dual market theory nor its critics have proposed potentially conclusive tests of the dual market hypothesis this paper presents a test of the two central propositions of dual market theory 1 the existence of two distinct labor markets with different wage setting mechanisms and 2 the existence of barriers to mobility between the labor markets we find considerable support for both hypothesis estimation of a switching model of wage determination with unknown regimes yields two distinct wage equations the one which most workers are associated with closely resembles the standard human capital regression with significant returns to education and experience the other equation is flat with no returns to human capital these two equations resemble the predictions of dual market theory for the primary and secondary markets respectively further we present evidence that at least some non white workers are involuntarily confined to the secondary market this crowding of minority workers into the low wage labor market accounts for a substantial portion of white non white wage differences we interpret these results as providing empirical support for the dual market hypothesis and for recent theoretical work on efficiency wagemodels in addition combining the efficiency wage argument with the observation that much of the white non white wage difference is explained by the exclusion of non whites from the primary sector suggests an explanation for the persistance of wage differences this abstract was borrowed from another version of this item

the role of regulatory learning in energy transition the case of solar pv in brazil abstract an important problem that has attracted significant amount of attention within the context of energy transitions is the carbon lock in a situation in which energy systems are locked in to high carbon technologies through a path dependent process several measures to avoid the carbon lock in involve technology specific measures which in turn implies that those measures may result in an energy system locked in to certain low carbon technologies we consider that the brazilian system needs policies to escape the carbon lock in which are based on providing incentives to low carbon technologies we develop an analytical framework to analyze the role of regulatory institutions in the possible lock in to utility scale photovoltaic in the sense that they create barriers to the adoption of distributed generation photovoltaic we show that the definition of a process to adapt the institutional framework in a context of stress in the innovation system is crucial for the adoption of new technologies applying our framework to the brazilian power sector we observe that only when regulators consider the possibility that the system is locked in to centralized production technologies and not when they just consider the carbon lock in they manage to eliminate barriers to distributed generation based on solar pv

the keynesian recovery although modem macro economic analysis has almost immortalized keynes s is lm framework it has largely ignored the central message of the general theory this is attributable at least in part to keynes s failure to provide a clear concept of market organization as an alternative to the walrasian auction paradigm recent developments however in the theory of search and transaction externalities may ultimately provide that missing concept also work on indeterminacy in rational expectations models may direct the profession s attention away from wage stickiness and back towards the intertemporal co ordination problems that keynes saw as lying at the root of unemployment la reprise keynesienne meme si l analyse macroeconomique moderne a presque immortalis6 le cadre d analyse is lm de keynes elle a en gros ignore le message central contenu dans sa theorie generale cela est attribuable au moins en partie au fait que keynes n a pas propose une notion claire d organisation du marche qui puisse remplacer le paradigme de l encan a la walras cependant certains developpements recents dans la theorie des cofuts de la recherche d un emploi des cofuts de transaction et des effets extemes que ce phenomene entraine pourraient fournir un des ces jours le chainon manquant i1 se pourrait aussi que les travaux sur l indetermination dans les modeles d anticipations rationnelles puissent aider a faire que l attention des membres de la profession economiste cesse d etre braquee sur les problemes de rigidit6 des salaires pour se fixer de nouveau sur les problemes de coordination intertemporelle qui etaient pour keynes au coeur du probleme du chomage it is an honour to be giving the harold innis memorial lecture for 1986 i m especially happy to be giving it in 1986 because this is the fiftieth anniversary of keynes s general theory of employment interest and money and i d like to take this occasion to speak on the subject of the influence keynes s central the 1986 harold innis memorial lecture presented at the canadian economics association meetings in winnipeg 29 may 1986 robert clower david laidler michael parkin and douglas purvis provided useful comments on the original lecture canadian journal of economics revue canadienne d economique xix no 4 november novembre 1986 printed in canada imprime au canada 0008 4085 86 626 641 1 50 canadian economics association this content downloaded from 157 55 39 244 on fri 17 jun 2016 05 48 33 utc all use subject to http about jstor org terms the keynesian recovery 627 message in the general theory has had on contemporary macro economics and the influence it is likely to have in coming years if i had been asked to address this subject five or ten years ago i would have made the lecture very short although the keynesian is lm apparatus was still the main organizing device of all intermediate macro textbooks and of most policy oriented economists keynesian theoretical ideas had virtually disappeared from the leading journals having been displaced by unkeynesian ideas such as perfect wage flexibility perfect foresight the absence of involuntary unemployment the pareto optimality of business cycle fluctuations and so forth keynesian policy advice had become downright disreputable in some academic circles and was clearly on the defensive everywhere as for the status of keynesian ideas in society at large keynes once expressed the wish that some day economists could get themselves thought of as humble competent people on a level with dentists 1930 332 by 1979 keynesian economists had become thought of the way i used to think of my dentist when i was ten years old with a mouth full of cavities and he could see no reason for using novocaine not humble or competent but a menace to society who was all the more dangerous because of his belief that he knew better than others what was good for them and because he now had his hands on some of the crucial policy instruments since 1979 the public status of keynesian ideas has fallen even further the madmen in authority are now distilling their frenzy from other defunct economists but i see signs of some recovery in the status of those ideas within the discipline of economics signs that at least they aren t yet completely dead what i d like to argue is that there is an important aspect of keynes s central message that was never incorporated into the mainstream of macro economic theory that the failure to incorporate this aspect is largely responsible for the decline of keynesian theoretical ideas but that some recent theoretical developments offer hope that that failure may finally be rectified

the equilibrium and optimal timing of price changes this paper studies the welfare properties of the equilibrium timing of price changes staggered price setting has the advantage that it permits rapid adjustment to firm specific shocks but the disadvantages that it causes unwanted fluctuations in relative prices and that by creating price level inertia it can increase aggregate fluctuations because each firm ignores its contribution to these problems staggering can be a stable equilibrium even if it is highly inefficient in addition there can be multiple equilibria in the timing of prices changes indeed whenever there is an inefficient staggered equilibrium there is also an efficient equilibrium with synchronized price setting

union wage settlements during a disinflation this paper examines the role of union wage contracts in the persistence of inflation and the implication of these contracts for the problem of disinflation in the united states a quantitative model of overlapping con tracts explicitly oriented toward the major union sector is developed the model takes account of expectations of future wage price and employment conditions as in more aggregated models that have been used in macroeconomic research in addition the distribution of workers according to contract length as well as deferred wage increases and escalator clauses are explicitly used in the model the main aim of the model is to determine the constraints which these contracts impose on disinflation paths the model indicates that the maximum speed of disinflation is extremely slow in the early phases if a rise in unemployment is to be avoided but increases considerably before the new lower rate of inflation is reached the disinflation path is considerably slower than that observed after hyperinflation periods however the existence of a path of inflation reduction raises questions about whether the institution of union wage con tracts is really the direct cause of costly disinflations or whether their influence works indirectly by raising credibility problems about a monetary disinflation this abstract was borrowed from another version of this item

deep transitions emergence acceleration stabilization and directionality abstract industrial society has not only led to high levels of wealth and welfare in the western world but also to increasing global ecological degradation and social inequality the socio technical systems that underlay contemporary societies have substantially contributed to these outcomes this paper proposes that these socio technical systems are an expression of a limited number of meta rules that for the past 250 years have driven innovation and hence system evolution in a particular direction thereby constituting the first deep transition meeting the cumulative social and ecological consequences of the overall direction of the first deep transition would require a radical change not only in socio technical systems but also in the meta rules driving their evolution the second deep transition this paper develops a new theoretical framework that aims to explain the emergence acceleration stabilization and directionality of deep transitions it does so through the synthesis of two literatures that have attempted to explain large scale and long term socio technical change the multi level perspective mlp on socio technical transitions and techno economic paradigm tep framework

changes in corporate effective tax rates over the past 25 years abstract we investigate systematic changes in corporate effective tax rates over the past 25 years and find that effective tax rates have decreased significantly contrary to conventional wisdom the decline in effective tax rates is not concentrated in multinational firms effective tax rates have declined at approximately the same rate for both multinational and domestic firms moreover within multinational firms both foreign and domestic effective rates have decreased finally changes in firm characteristics and declining foreign statutory tax rates explain little of the overall decrease in effective rates

the rigidity of prices this paper uses evidence on individual transaction prices to analyze price behavior the evidence shows that for many transactions pricesremain rigid for periods exceeding one year the rigidity of price ispositively correlated with industry concentration for several productsthe correlation of price changes across buyers is low the paper alsoinvestigates the relationship between price rigidity price change andthe length of time a buyer and seller have been doing business together the author interprets the evidence as emphasizing the importance of nonprice rationing and the inadequacy of models in whichprice movements alone clear markets copyright 1986 by american economic association

sectoral systems of innovation and production the concept sectoral system of innovation and production provides a multidimensional integrated and dynamic view of sectors it is proposed that a sectoral system is a set of products and the set of agents carrying out market and non market interactions for the creation production and sale of those products a sectoral systems has a specific knowledge base technologies inputs and demand agents are individuals and organizations at various levels of aggregation they interact through processes of communication exchange co operation competition and command and these interactions are shaped by institutions a sectoral system undergoes change and transformation through the co evolution of its various elements 2002 elsevier science b v all rights reserved

real effects of accounting rules evidence from multinational firms investment location and profit repatriation decisions we analyze survey responses from nearly 600 tax executives to better understand corporate decisions about real investment location and profit repatriation our evidence indicates that avoiding financial accounting income tax expense is as important as avoiding cash income taxes when corporations decide where to locate operations and whether to repatriate foreign earnings this result is important in light of the recent research about whether financial accounting affects investment and in light of the decades of research on foreign investment that examines the role of cash income taxes but heretofore has not investigated the importance of financial reporting effects our analysis suggests that financial reporting is an important factor to be considered in the policy debates focused on bringing investment to the united states

optimum pricing policy under stochastic inflation we describe aggregate inflation as a stochastic process in which the rate of change of the price level can be positive or zero where the times spent in each state are of random duration this class of processes includes two state markov chains and renewal processes as special cases it is shown that the optimal pricing policy of a monopolistic firm with non convex costs of price adjustment is s s in its real price i e its nominal price relative to the price level a basic certainty equivalence result is proved i e the firm behaves as if it faces a certain and fixed rate of inflation higher than the actual expected rate the difference between the two rates being a risk premium which depends on the real interest rate and the parameters of the stochastic process one can thus apply previous results from the case of certainty sheshinski and weiss review of economic studies 1977 to obtain comparative static results in particular one finds that an increase in the variance of expected inflation leads firms to choose a pricing policy with larger amplitude in real price the paper also addresses the question of consistency in firms expectations when the price level is determined by the firms actions in this paper we consider pricing policies of individual firms in an inflationary environment each firm expects the general price level to increase and must determine the rate of increase of its own price it is assumed that the firm incurs an adjustment cost when it changes its nominal price consequently firms choose to change prices occasionally rather than continuously

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

goodwin cycles and the bopc growth paradigm a macrodynamic model of growth and fluctuations abstract the paper builds a non linear macrodynamic model to study the relation between the functional distribution of income technological progress and economic growth in the short term the interaction between the productivity regime the demand regime and the distributive conflict generates cyclical paths a la goodwin in the long term output growth rate is constrained by the balance of payments a la thirlwall in which the elasticities of foreign trade are modeled as a function of the complex relation between the wage share and the innovation capabilities of theeconomy

surprise party estimating the consequences of unexpected presidential election results alesina s quarterly journal of economics 102 651 678 1987 influential model of presidential elections with ideologically motivated parties attributes higher growth and lower unemployment under democratic presidents to the surprise inflation a democratic victory entails in contrast to the published literature we test this hypothesis using calcula tions of presidential election surprises consistent with the assumption of rational economic actors we confront the econometric complications attending a time series approach tak ing into account economic growth dynamics we ultimately fail to confirm the hypothesis that the level of uncertainty associated with presidential election results has an effect on economic outcomes

aggressive tax avoidance by managers of multinational companies as a violation of their moral duty to obey the law a kantian rationale managers of multinational companies often favour an aggressive tax avoidance strategy that pushes the legal limits onto the advantage of shareholders and the disadvantage of the spirit of democratically legitimized tax laws the public and media debate whether such aggressive behaviour is immoral aggressive tax avoidance is a subset of the aggressive legal interpretations potentially observable in all fields which places little weight on the will of a democratically legitimized legislation a thorough ethical analysis based on the deontological approach of kant demonstrates that aggressive tax avoidance as a special case of operating on the edge of legal boundaries is potentially immoral applying the kantian contradiction of conception or will test shows that this maxim might not be conceived or willed as a general law of nature if all natural or legal persons aggressively interpret laws on all subjects and in every imaginable situation then central principles of the system of law we all rely upon would be severely compromised therefore aggressive tax avoidance by managers of multinational companies may violate the managers moral duty to obey not only the letter but also the intention or spirit of the law the validity of the argumentation depends critically on the formulation and interpretation of the respective maxims and on assumptions about the legal system preserving central elements of kantian philosophy the article demonstrates the complexity of a philosophical argumentation which tries to justify the moral intuitions that underpin the common negative evaluation of aggressive legal strategies in business

monetary policy rules targets and shocks the proper conduct of monetary policy is now once again wide open to discussion an immediate practical controversy concerns the role of central banks in recovery from the world depression underlying that debate are some unresolved fundamental issues regarding the responsibilities goals targets and operating procedures of central banks monetarism won the hearts and minds of many economists and most central bankers in the 1970s now it seems to be losing adherents and influence partly because it is blamed for the severe depression partly because regulatory institutional and technological changes have altered the meanings and velocities of monetary aggregates last summer chairman volcker and his federal reserve colleagues suspended their monetarist targets to almost universal relief the severity of the recession the international debt crisis and the pace of change in financial structure were all good reasons it is doubtful though possible that money stock targets will regain their previous status if not what philosophy of monetary control what framework for the conduct of policy will replace them a host of monetary architects are ready to fill the vacuum some would restore the gold standard or make paper money convertible into other commodities some would replace intermediate monetary aggregates with other targets the monetary base nominal gnp or final sales total domestic credit price indexes or their rates of change exchange rates some advocate irrevocable commitment to announced

have financial statements lost their relevance the authors explore the concern that financial statements no longer have the same relevance to investors that they had in the past they test for value relevance by measuring the total return that could have been earned from prior knowledge of financial statement information and by examining the explanatory power of accounting information on market values and annual market adjusted returns both analyses are applied to a broad sample of exchange listed and nasdaq firms for the 1952 94 period the authors find mixed evidence on value relevance of financial statement reporting during the test period

price inertia and policy ineffectiveness in the united states 1890 1980 this paper introduces a new approach to the empirical testing of the lucas sargent wallace lsw policy ineffectiveness proposition which compares the lsw hypothesis with an alternative that states that prices respond fully in the long run but only gradually in the short run to nominal aggregate demand disturbances the empirical equations estimated for a new set of quarterly data extending back to 1890 exhibit uniformly high responses of real output and low responses of price changes to anticipated changes in nominal gnp the paper compares and tests three alternative methods of introducing persistence effects into the lsw framework

the estimation of prewar gross national product methodology and new evidence the paper develops new methodology for the estimation of prewar gnp taps previously unused data sources and develops new estimates for the periods 1869 1908 and 1869 1928 primary among the new data sources are direct measures of output in the transportation communications and construction sectors and estimates of the consumer price index new measures of real gnp nominal gnp and the gnp deflator are developed the new estimates of real gnp are as volatile on average over the business cycle as the traditional kuznets kendrick series but dampen the amplitude of some cycles while raising the amplitude of others the new estimates of the gnp deflator are distinctly less volatile than the traditional series and in fact no more volatile than those in the postwar period

international profit shifting within multinationals a multi country perspective abstract we model the opportunities and incentives generated by international tax differences for international profit shifting by multinationals the model considers not only profit shifting arising from international tax differences between affiliates and parent companies but also from tax differences between affiliates in different host countries our model yields the prediction that a multinational s profit shifting in a country depends on a weighted average of international tax rate differences between all countries where the multinational is active using a unique dataset containing detailed firm level information on the parent companies and subsidiaries of european multinationals and information about the international tax system we test our model and empirically examine the extent of intra european profit shifting by european multinationals on average we find a semi elasticity of reported profits with respect to the top statutory tax rate of 1 3 while shifting costs are estimated to be 0 6 of the tax base international profit shifting leads to a substantial redistribution of national corporate tax revenues many european nations appear to gain revenues from profit shifting by multinationals largely at the expense of germany

the nairu unemployment and monetary policy this paper examines the precision of conventional estimates of the nairu and the role of the nairu and unemployment in forecasting inflation the authors find that although there is a clear empirical phillips relation the nairu is imprecisely estimated forecasts of inflation are insensitive to the nairu and there are other leading indicators of inflation that are at least as good as unemployment this suggests deemphasizing the nairu in public discourse about monetary policy and instead drawing on a richer variety of leading indicators of inflation

on sluggish output adjustment and exchange rate dynamics abstract this paper develops a model of exchange rate dynamics which incorporates sluggish output adjustment into the dornbusch variable output model in this more complex system monetary expansion initially lowers interest rates because of sluggish output adjustment but quite surprisingly still can produce either overshooting or undershooting of the exchange rate as in the basic model however if undershooting occurs the exchange rate subsequently moves away from its new long run equilibrium level furthermore the perfect foresight exchange rate expectations scheme now contains a perversely signed parameter thus variable output does not appear to be a reasonable basis for exchange rate undershooting jel f31
