corporate social responsibility and profit volatility theory and empirical evidence corporate social responsibility csr implies extra care for the well being of stakeholders different from shareholders in our theoretical model we show that when this principle implies that more csr oriented companies incorporate stakeholders well being constraints it translates into higher sensitivity of profits to economic shocks our empirical analysis finds support for this hypothesis showing that csr attributes which relate to positive contributions to stakeholders well being significantly and positively affect idiosyncratic profit volatility our findings remain robust when controlled for endogeneity with instrumental variable estimates

more shock than therapy market transition employment and income in russia 1991 1995 sixteen predictions from market transition theory are assessed using survey data on employment earnings and income in russia during the first five years of market reform although the private sector has grown self employment is still rare incomes are down and unemployment is up a distended income distribution reflects unprecedented income inequality distinctive features of late soviet era stratification persist low returns to education a gender gap in earnings and low earnings among professionals the russian market transition offers more opportunity in trade consumer services and speculation and less in manufacturing than do other emerging makets this corresponds to merchat capitalism and contradicts the predictions of market transition theory everything the communists told us about communism was a lie everything they told us about capitalism turns out to be true popular russian joke circa 1996

innovative r d and optimal investment under uncertainty in high tech industries an implication for emerging economies abstract in order to continue on the path to convergence with advanced countries emerging countries need to strengthen their research capabilities often they try to do this through the development of strategic industries the objective of this paper is to contribute to the debate on the effectiveness of policies aimed at the development of strategic industries in emerging economies the paper develops a three phase model for product innovation with capital investment under uncertainty to study the investment decisions of a manufacturer in an industry facing a volatile market demand for new inventions the findings demonstrate the importance of interactions between market structure a firm s market power and the associated cost of adjustment the paper draws out implications for emerging economies with regard to policies striving to develop strategic industries in sectors such as semiconductors and information technology

a note on competitive investment under uncertainty uncertainty over future output prices or input costs can affect investment by a riskneutral firm in two opposing ways first it can increase the value of the marginal unit of capital which leads to more investment this only requires that the stream of future profits generated by the marginal unit be a convex function of the stochastic variable by jensen s inequality the expected present value of that stream is increased this result was demonstrated by richard hartman 1972 and later extended by andrew abel 1983 and others in their models constant returns to scale and the substitutability of capital with other factors ensure that the marginal profitability of capital is convex in output price and input costs even with fixed proportions however this convexity can result from the ability of the firm to vary output so that the marginal unit of capital need not be utilized at times when the output price is low or input costs are high if investment is irreversible and can be postponed a second effect of uncertainty is to create an opportunity cost of investing now rather than waiting for new information to arrive before committing resources this increases the full cost of investing in a marginal unit of capital which reduces investment 2 hence the net effect of uncertainty on irreversible investment depends on the size of this opportunity cost relative to the increase in the value of the marginal unit of capital the sign of the net effect is significant because of its possible policy implications pindyck 1988 and giuseppe bertola 1989 developed models in which a firm faces a downward sloping demand curve and found the net effect to be negative ricardo caballero 1991 has recently studied investment by an individual firm facing a stochastically shifting demand curve he shows that as returns to scale become constant and the elasticity of demand faced by the firm rises this opportunity cost of investing now rather than waiting approaches zero thus in the limit of constant returns and an infinitely elastic demand curve an increase in uncertainty tends to raise rather than decrease current investment even if that investment is irreversible it is important to stress that caballero s limiting result treats the firm in isolation and describes the effect of a meanpreserving increase in price uncertainty and not an increase in industry wide demand uncertainty this note shows that in a competitive market the key interactions between irreversibility and uncertainty occur at the industry level and can only be understood by making price and industry output endogenous 3 doing so restores the positive opportunity cost associated with irreversible investment in addition caballero s result is based on a model with convex adjustment costs an innovative aspect of the model is that these costs can be asymmetric thereby allowing for partial or complete irreversibility complete irreversibility corresponds to a cost of massachusetts institute of technology cambridge ma 02139 this work was supported by the national science foundation under grant no ses 8618502 and by mit s center for energy policy research my thanks to julio rotemberg and especially ricardo caballero for very helpful comments and discussions 1then the marginal profit of capital at each time t in the future is max o pt ct where ct is variable cost thus a unit of capital represents a set of all options on future production which are worth more the greater the variance of pt or ct 2for a detailed discussion of this point and a survey of the recent literature on irreversibility and its implications for investment and market evolution see pindyck 1991 3studies that make price endogenous include steven lippman and richard rumelt 1985 avinash dixit 1989 1991 and john leahy 1990

technology acquisition with technological progress effects of expectations rivalry and uncertainty abstract we study the effect of expectations regarding technological progress on a firm s technology adoption decision in a duopoly new generation technologies become available one in each period with successive generations representing better and better performance a game theoretic framework is used involving two identical firms competing in the same market over two periods it is shown that expectations retard adoption of the first period technology it is also shown that an asymmetric equilibrium results in higher social welfare and that more investment does not necessarily mean higher levels of welfare uncertainty is shown to have either no effect or a negative effect on the adoption of the current technology when nash equilibrium holds however when subgame perfect equilibrium holds uncertainty has a more complicated effect and numerical examples show that it may even encourage the adoption of the current technology relative to the deterministic equilibrium

dynamic game results of the acquisition of new technology open and closed loop nash strategies are derived and analyzed for a differential game in which two competing firms choose prices and productive capacity where new technology reduces a firm s unit operating cost using an open loop strategy a firm makes an irreversible commitment to a future course of action for example a contract with a labor union may force a firm to commit to maintaining its entire workforce regardless of its competitor s future realized behavior in contrast using a closed loop strategy a firm s decisions evolve over time continuously responding to the competitor s behavior the dynamic nash strategies obtained for the closed loop model exhibit a more restricted acquisition of new technology and a greater reduction of existing capacity relative to the open loop solutions in addition the dynamic nash price to be charged for output is higher in the closed as opposed to open loop competitive environment numerical solutions are presented to demonstrate that if both firms apply the closed loop approach each will earn higher profits than if one or both firms choose an open loop strategy

monetary policy macro stability and growth there is greater appreciation now amongst economists of the negative effect of uncertainty on investment growth and equality especially when credit constraints are widespread this implies an important linkage between the transparency and predictability of the policy environment and growth and equality the paper begins with a literature survey on the inflation and inflation volatility link the uncertainty and investment link and the inflation volatility and growth link this framework is used to examine the experience of south africa s new monetary policy regime inflation targeting it in achieving greater macrostability south africa is an interesting case study being one of the more advanced of the emerging markets with its deep and sophisticated financial system and yet with around 35 percent unemployment and a legacy of developmental problems from the apartheid era the authors demonstrate using evidence from three sources of micro data that the new monetary regime is more credible transparent and predictable they examine the performance of monetary policy and argue it has not resulted in real interest rate levels that are a hindrance to growth they explore the better response under it to big external shocks like exchange rate depreciation as compared with the monetary regime prior to it the paradox is examined of success in achieving macro stability where greater household acquisition of debt and increased demand is both inflationary and limits saving hence constraining corporate investment the paper concludes with lessons from south africa s recent successful monetary policy experience for other emerging market countries and for less developed countries central banks e g in africa

the effect of business risk on manufacturing investment sectoral survey evidence from ireland abstract this paper analyses the results of a special sample survey on risk and investment carried out using the european union investment survey sampling frame for ireland the paper looks at decision making by large manufacturing firms located in ireland to see whether their investment decisions can be understood within the various models of risk that economists use equilibrium and disequilibrium models are examined to see what best explains the behaviour revealed by the firms responses the paper develops a categorisation of the main theoretical channels of influence from risk to investment in the light of this theory the survey replies of irish firms are used to assess the importance of the different channels of influence

fast high precision decision rules for valuing manufacturing flexibility abstract the valuation of flexible manufacturing systems is one of the most frequently undertaken productivity improvement activities in practice the introduction of an fms into industry must be done on the basis of cost justification recently developed techniques for the evaluation of the value of flexibility typically include the computation of stochastic dynamic programs however the computational effort of stochastic dynamic programs grows combinatorially and limits application to real world problems in this contribution we derive fast approximations to the stochastic dynamic program and compare their results to the exact solution the proposed methods show an excellent worst case behavior 1 for a wide range of volatility of the underlying stochastic profit margins and costs for switching the production mode the computational effort is reduced by a factor of more than 200

investment and competition this paper examines how industry structure affects corporate investment patterns real options theory shows that deferring irreversible investment in the face of uncertainty is valuable theory also shows that the value of waiting to invest falls if investment opportunities are contestable consistent with these theories we find that firms in monopolistic industries exhibit lower investment q sensitivity and are slower to invest than firms in competitive industries however we find that investment q sensitivity and investment speed are highest in oligopolistic industries suggesting that the value of investing strategically can outweigh the value of waiting indeed oligopolistic industries experience less entry and more exit than other industries

technological expectations and adoption of improved technology abstract attention is focused upon the adoption demand rather than the creation supply of new technology which improves from time to time based on the expected flow of technological progress over which the firm demander has no control it must decide either to adopt the current best available technology or to postpone adoption the distinguishing features of the model are that more than one technological innovation is anticipated and expectations about the likelihood of such innovations are revised as time passes since the last innovation our analysis shows that the firm will adopt the current best practice if its technological lag exceeds a certain threshold moreover as time passes without new technological advances it may become profitable to purchase a technology that has been available even though it was not profitable to do so in the past

product market competition and the impact of price uncertainty on investment some evidence from us manufacturing industries the authors estimate the impact of price uncertainty on investment using a panel of u s manufacturing industries pooling the data for all industries uncertainty has no impact on current investment however for industries that have low levels of seller concentration and thus are likely to be highly competitive the estimated impact is negative and statistically significant while for industries with high levels of seller concentration the impact is always small and not significantly different from zero the finding of a negative relationship between investment and price uncertainty in competitive industries is broadly consistent with models that incorporate irreversibility of capital investment copyright 1996 by blackwell publishing ltd

economic reforms and democracy evidence of a j curve in latin america this article explores the relationship between economic reforms and democracy in latin america between 1970 and 1995 existing theories suggest divergent effects across time horizons the implementation of reforms economic liberalization may initially destabilize democracy due to popular backlash or overzealous reformers usurpation of democratic institutions however the potential outcome of reforms greater economic liberalism may later foster or reinforce democracy by dispersing economic assets making rulers more susceptible to international constraints or demobilizing social groups that may otherwise make politically destabilizing redistributive demands time series cross section analyses using an error correction model provide evidence of this j curve relationship although countries engaging in economic reforms may experience a temporary deterioration of democracy they tend to become more democratic in the long run findings are robust to numerous control variables country and time fixed effec

flexibility and firm diversity with demand fluctuations abstract this paper examines how demand induced output fluctuations are distributed by competitive firms within industries it shows that competitive equilibria in fluctuation prone industries may support technologically diverse firms some firms are more flexible than others and absorb a disproportionate share of industrywide output fluctuations others are less flexible and have output levels more stable than the industry as a whole their coexistence in competitive equilibrium is due to a tradeoff between flexibility and static efficiency within the discrete set of available production technologies

it pays to be different endogenous heterogeneity of firms in an oligopoly abstract heterogeneous firms can be supported by familiar conditions of technology and demand in a two stage duopoly game firms choose technologies simultaneously in stage i from a continuous technology set in stage ii once technological commitments have been made firms choose quantities and the equilibrium price is determined if the technology set is insufficiently convex firms choose only the extreme production technologies in some cases they choose the same technology in others they choose different technologies when compared to socially optimal industry structures equilibria tend to have too little heterogeneity uncertainty about demand or costs favors the emergence of heterogeneous firms

integrating financial theory and methods in electricity resource planning decision makers throughout the world are introducing risk and market forces in the electric power industry to lower costs and improve services incentive based regulation ibr which replaces cost of service ratemaking with an approach that divorces costs from revenues exposes the utility to the risk of profits or losses depending on their performance regulators also are allowing for competition within the industry most notably in the wholesale market and possibly in the retail market two financial approaches that incorporate risk in resource planning are evaluated risk adjusted discount rates radr and options theory ot these two complementary approaches are an improvement over the standard present value revenue requirement pvrr however each method has some important limitations by correctly using radr and ot and understanding their limitations decision makers can improve their ability to value risk properly in power plant projects and integrated resource plans

the trade balance and fiscal policy in the oecd abstract we explore the short run impact of movements in different components of fiscal policy on the trade balance exports and imports for a panel of oecd countries over 1960 1995 we find that the composition of a shift in fiscal policy and the exchange rate regime matter for its transmission to the external account the strongest result is that an expansion in wage government consumption causes a contraction in exports and a deterioration of the trade balance especially under flexible exchange rates we discuss the implications of our results for fiscal and current account adjustment

real options delay vs pre emption do industrial characteristics matter this paper presents an empirical study of the channels of influence from uncertainty to fixed investment suggested by real options theory using panel data from the confederation of british industry cbi industrial trends survey we report ols estimates of the impact of uncertainty on investment where the regressors are augmented by cross sectional averages of the dependent variable and of the individual specific regressors as recently suggested by pesaran pesaran m h 2006 estimation and inference in large heterogeneous panels with a multifactor error structure econometrica 74 967 1012 the cross industry pattern of results is checked for consistency with the pattern predicted by real options theory using a specially constructed data set of industrial characteristics we find that irreversibility is able to predict the pattern detected but only when combined with a measure of the information advantage of delay there is also evidence for expansion options effects industries with high r d and advertising intensities tend to have positive uncertainty effects

continuous time methods in finance a review and an assessment i survey and assess the development of continuous time methods in finance during the last 30 years the subperiod 1969 to 1980 saw a dizzying pace of development with seminal ideas in derivatives securities pricing term structure theory asset pricing and optimal consumption and portfolio choices during the period 1981 to 1999 the theory has been extended and modified to better explain empirical regularities in various subfields of finance this latter subperiod has seen significant progress in econometric theory computational and estimation methods to test and implement continuous time models capital market frictions and bargaining issues are being increasingly incorporated in continuous time theory the roots of modern continuous time methods in finance can be traced back to the seminal contributions of merton 1969 1971 1973b in the late 1960s and early 1970s merton 1969 pioneered the use of continuous time modeling in financial economics by formulating the intertemporal consumption and portfolio choice problem of an investor in a stochastic dynamic programming setting merton 1973b also showed how such a framework can be used to develop equilibrium asset pricing implications thereby significantly extending the asset pricing theory to richer dynamic settings and expanding the scope of applications of continuous time methods to study problems in financial economics 1 within a span of about 30 years from the publication of merton s inf luential papers continuous time methods have become an integral part of financial economics indeed in certain core areas in finance such as e g asset pricing derivatives valuation term structure theory and portfolio selection continuoustime methods have proved to be the most attractive way to conduct research and gain economic intuition the continuous time approach in these areas has produced models with a rich variety of testable implications the econometric theory for testing continuous time models has made rapid strides in the last decade and has thus kept pace with the impressive progress on the theoretical front one hopes that the actual empirical investigations and estimation using the new procedures will follow suit soon

the transition to a market economy pitfalls of partial reform we present a theory of a partial economic reform of a planned economy similar to the one that took place in russia since 1988 and in china earlier in such a reform some markets are liberalized in the sense that producers can sell output to whomever they want including private firms at free prices but at the same time must sell to state firms at state prices we show that such a reform can result in a substantial diversion of subsidized inputs away from state firms and toward private firms even when state firms value these inputs more the result may be a reduction of total output the simple analysis sheds light on many consequences of the soviet reform such as breakdown of coordination of production increased state policing of delivery quotas prohibitions of trading cooperatives and opposition to privatization the model also explains why partial reform failed in russia but worked in china

investment with uncertain tax policy does random tax policy discourage investment we consider the impact of tax policy uncertainty on firm level and aggregate investment comparing investment behaviour when uncertainty is due to a shock following geometric brownian motion gbm versus when random discrete jumps in tax policy occur expectations of the likelihood of a tax policy switch have an important negative impact on the gain to delaying investment in the latter model and time to investment can fall with increasing tax policy uncertainty aggregate investment simulations indicate that capital formation is adversely affected by increases in uncertainty in the traditional gbm model but can be enhanced in the jump process model

industry wide versus firm specific uncertainty and investment british company panel data evidence this paper presents evidence on the prediction that the impacts of firm specific and industry wide uncertainty on investment will be different results show that these work in opposing directions and that the effect of industry specific uncertainty is stronger in concentrated industries

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

the role of technological expectations in a mixed model of international diffusion of process innovations the case of open end spinning rotors abstract in the years following the introduction of open end rotors a major innovation in cotton spinning technological change in spinning has been characterized by fast rates of introduction of incremental innovations this has made possible considerable improvements in the quality of products as well as reductions in the cost of spinning this case seems especially appropriate for analysing the effects of incremental innovations on the rate of diffusion one the one hand expectations of continuing incremental change may have actually slowed the diffusion of open end rotors contrarily increased profitability from their adoption may have reinforced the rate of diffusion a mixed model of diffusion one that is able to evaluate the role of supply forces such as the introduction of incremental innovations and at the same time the role of bounded rationality and learning by imitating has been developed it draws on the behavioural literature and upon the epidemic approach due to mansfield results of an econometric test on international data available for 26 countries confirm that the rate of introduction of incremental innovations has reduced the rate of diffusion this is especially the case in countries where the technological change in spinning was originated and consequently technological expectations were higher

democratization and economic liberalization in the postcommunist world how does economic liberalization affect political regime economic liberalization is widely regarded as inimical to democratization the washington consensus which generally endorses shock therapy and envisions a basic compatibility between economic liberalization and democratization is widely disdained in social science many scholars hold that neoliberal economics depresses popular living standards and exacerbates socioeconomic inequalities thereby compromising democratization focusing on the postcommunist region this article tests this hypothesis it examines the data that have been used to assess the relationship between economic liberalization and political democratization and presents analyses using more appropriate and differentiated techniques the authors find that economic liberalization advances rather than undermines democratization using engle granger analysis they find that although economic liberalization has no discernible impact on democratization in the short term democratiza

reputations in the adoption of a new technology abstract this paper studies the effects of uncertainty on the timing of adoption of a new technology in a duopoly firms are uncertain of the innovative capabilities of their rivals and about the profitability of adoption these features lead to a richer and in some respects more plausible theory of adoption in which rents from delayed adoption are always realized and returns are not equalized across adoption times

investment under uncertainty and the value of the firm abstract the investment behavior of a monopolistic firm with a constant returns to scale production function facing a randomly shifting elastic demand is examined uncertainty can have a negative effect on the value of the firm and on investment

the effects of government expenditure on imports in the eurozone reconsidered evidence from panel data abstractthis study examines the impact of government expenditure on imports the empirical analysis is based on annual data of the euro area countries for the period 1995 2015 we employ econometric methods that mitigate heterogeneity and cross sectional dependence we provide empirical indications that the components of expenditure have different impact on imports demand the findings of this study indicate that the import context of government expenditure is lower than the import context of others expenditure components finally we find that an increase in government expenditure leads to an increase in imports this implies that ceteris paribus that it can lead to a deterioration of the trade balance

timing of investment under technological and revenue related uncertainties the effects of two forms of uncertainty on the timing of irreversible investment are considered technological uncertainty is modeled as a poisson arrival process that reduces the cost of investment while revenue uncertainty is modeled as a diffusion process technological uncertainty has no effect on the optimal investment policy when revenue uncertainty is absent however when combined with revenue uncertainty increased technological uncertainty makes investment less attractive relative to waiting the paper also makes a more general point in clarifying the difference in how diffusion type of uncertainty and unidirectional stochastic progress affect investment timing

the effects of public spending shocks on trade balances and budget deficits in the european union we investigate the consequences of an increase in public spending for trade balances and budget deficits in the european union using a panel var approach whereas the literature tends to treat the trade balance gdp ratio as a single variable we include exports and imports as separate variables this allows us to track in more detail the sources of trade balance movements further we use annual rather than quarterly data this facilitates the interpretation of the shocks and reduces potential anticipation effects of fiscal policy changes however the identification assumptions become stronger and we extensively check their validity according to our baseline estimate a 1 gdp increase in public spending produces a 1 2 on impact with a 1 6 peak rise in gdp rising imports and falling exports are responsible for a fall of the trade balance by 0 5 of gdp on impact and a peak fall of 0 8 in addition the spending increase produces a 0 7 impact and peak budget deficit thereby pointing to the potential relevance of the twin deficits hypothesis for the european union jel e62 h60

hedging the value of waiting abstract we analyze the optimal hedging policy of a firm that has flexibility in the timing of investment conventional wisdom suggests that hedging adds value by alleviating the under investment problem associated with capital market frictions however our model shows that hedging also adds value by allowing investment to be delayed in circumstances where the same frictions would cause it to commence prematurely thus hedging can have the paradoxical effect of reducing investment we also show that greater timing flexibility increases the optimal quantity of hedging but has a non monotonic effect on the additional value created by hedging these results may help explain the empirical findings that investment rates do not differ between hedgers and non hedgers and that hedging propensities do not depend on standard measures of growth opportunities

research and development cash flow agency and governance uk large companies this paper investigates the determinants of r d expenditure using a sample of uk listed companies with the highest spend from 2000 to 2005 we investigate the effect of corporate governance and ownership on r d using panel data the results provide some evidence that more governance tends to depress r d activity a finding that is robust to whether a composite or disaggregated index of governance is used one innovation of the paper is that we treat agency and finance effects interactively the ownership stake of the ceo appears to be supportive for r d

contrasting effects of risk on investment in two sectors evidence from ireland on real options abstract this note contrasts investment behaviour under risk in the two main indigenous manufacturing sectors of the irish economy this is of interest because these sectors display pronounced contrasting characteristics which facilitate the testing of theories of real options and irreversible investment

an evolutionary pattern of innovation diffusion the case of flexible automation abstract the aim of this paper is to provide evidence supporting an evolutionary model of the process of innovation diffusion relying on an extensive field study the paper analyses the pattern of adoption of the entire set of innovations deriving from the flexible automation paradigm on the part of a large sample of italian metalworking firms owing to the relevance of the technology examined and to the size of the sample the case illustrates quite representatively the dynamics of the early stage of development of radical and complex innovations the main results of the paper confirm the importance of firm size and market structure to explain the characteristics of the innovation diffusion process at the same time they emphasize that the localized search procedures on the part of potential users involve a step by step approach to adoption namely the technological and organizational profile of firms turns out to play a decisive role in favouring diffusion moreover empirical support is provided for the existence of persistent market disequilibria along the diffusion paths witnessed by the extent of the retrofitting phenomenon

modeling strategic investment decisions under sequential technological change strategic decisions to invest in new equipment are critical not only because of the large initial capital costs incurred but even more importantly because they affect future unit production costs revenues and the ability of the firm to perform operations that were not possible earlier thus these decisions determine the very competitiveness of the firm further decisions regarding the choice of technology are very expensive to correct if incorrect decisions are identified these decisions have become increasingly urgent and complex because the state of the art in technology is changing rapidly however many models available for evaluating these decisions are either too complex and inefficient or too restrictive in the number types and the way appearance of future technologies is modeled this research attempts to relax some of these restrictions using forecast horizon procedures to model capital investment decisions where any number of technologies may appear in the future with purchase costs and revenues that may vary over time the appearance of these future technologies are considered uncertain with probabilities that may also vary with time however we assume that the order in which they appear is sequential much like the different generations of microchips for microcomputers we develop a new approach using nonunique terminal rewards to solve a dynamic programming model of the problem by introducing converse difference functions and present an algorithm that is both simple and efficient despite the increase in state space from the use of converse functions we show that the computational burden of the algorithm does not increase numerical examples are given to illustrate our algorithm sensitivity of the optimal decision to changes in probabilities costs and revenues are also discussed

the state and economic involution russia through a china lens abstract why has the russian economy declined at the rate the chinese economy has grown in china the party state has made possible the decentralization of property relations and the hardening of budget constraints whereas in russia the disintegration of the party state has led to privatization and soft budget constraints whereas the former combination entailed accumulation the latter combination entailed involution that is an economy that eats away at its own foundations by funnelling resources from production to exchange russia s involution has proceeded in a combined mode that is through a series of phases in which government policies try to rectify the unintended consequences of previous policies involution is also uneven as different industries adopt different strategies some rapidly exited from the old order and then disintegrated while others voiced their demands to the state and declined more slowly

adoption of competing inventions by united states steel producers a hstract this research investigates innovative behavior in the u s steel industry under the assumption that basic oxygen and large electric furnaces are competing technologies the empirical model of innovation is based on recent theoretical research the coefficients are estimated by a seemingly unrelated tobit approach the research finds innovation is strongly influenced by a demonstration effect adoption is also influenced by potential cost savings and technical progress there is no evidence that large u s steel producers modernized more slowly than their smaller rivals the large electric furnace becomes sufficiently attractive by 1980 that firms choose not to adopt basic oxygen

fiscal policy the real exchange rate and traded goods we estimate the effects of government spending shocks on the cpi real exchange rate the trade balance and their co movements with gdp and private consumption we decompose the variations of the cpi real exchange rate into variations of the traded goods real exchange rate and the relative price of traded to non traded goods we reach three main conclusions a rise in government spending induces a depreciation of the cpi real exchange rate and a trade balance deficit private consumption rises in response to a government spending shock and therefore co moves positively with the real exchange rate both components of the cpi real exchange depreciate we employ vector auto regression var techniques to estimate the effects of fiscal policy and in particular government spending on the cpi real exchange rate and the trade balance in the us and three other oecd countries our empirical analysis delivers two key results first a rise in government spending tends to induce a real exchange rate depreciation and a trade balance deficit although especially in the us the latter effect tends to be small second in all countries private consumption rises in response to a government spending shock and therefore co moves positively with the real exchange rate two important implications follow from these results our evidence provides support for a traditional twin deficit hypothesis in stark contrast with a recent study by kim and roubini 2008 a second implication concerns the consistency of facts and theory both the response of the real exchange rate and its co movement with private consumption and the trade balance are at odds with a benchmark general equilibrium open economy model featuring complete financial markets in fact while the model is successful in replicating the negative response of the trade balance to a government spending shock that we observe in the data and also in linking the magnitude of that response to the degree of openness it has counterfactual predictions on the response of the real exchange rate and of private consumption we argue that the key failure of the model lies in the equilibrium behaviour of private consumption in the model as a result of a typical wealth effect on labour supply private consumption falls in response to a rise in government spending whereas the opposite is true in the data this in turn explains the behaviour of the real exchange rate in the reference model with complete asset markets a risk sharing arbitrage condition ties the ratio of the marginal utilities of consumption across countries to the real exchange rate via this condition and provided that deviations from purchasing power parity are feasible the fall in consumption is accompanied by an equilibrium appreciation of the real exchange rate we proceed by investigating further the sources of the cpi real exchange rate movements in the data a traditional approach decomposes the real exchange rate into two terms

firms investment decisions in response to demand and price uncertainty we investigate the effect of demand and price uncertainty on firms planned and realized investment from a panel of manufacturing firms uncertainty measures are derived from firms own expectations about demand and prices and firm s sales we find that demand uncertainty at the time of planning depresses planned and subsequent realized investment firms do not revise their plans due to demand uncertainty at the time of spending suggesting that reducing demand uncertainty will only have lagged effects on investment we do not find any effect of price uncertainty our results are consistent with the behaviour of monopolistic firms with irreversible capital

on the sign of the investment uncertainty relationship understanding the effects of uncertainty over any decision variable has fascinated economists for a long time risk aversion and incomplete markets are likely to make the investment uncertainty relationship negative e g roger craine 1989 joseph zeira 1989 what happens in the absence of risk aversion and incomplete markets is however ambiguous richard hartman 1972 and andrew b abel 1983 1984 1985 found that in the presence of symmetric convex costs of adjustment mean preserving increases in price uncertainty raise investment of a competitive firm as long as the profit function is convex in prices on the other hand the recent literature on irreversible investment e g robert s pindyck 1988 giuseppe bertola 1988 has shown that increases in uncertainty lower investment all these results have been derived under either risk neutrality or complete markets intuition suggests that the explanation for such a difference lies with the asymmetric nature of adjustment costs in the irreversible investment case as compared with the symmetry of the adjustment cost mechanisms proposed by abel and hartman although this intuition is confirmed in this paper asymmetric adjustment costs are shown not to be sufficient to explain why the results differ in fact a more hidden but at least as important difference between these two literatures is that the former assumes perfect competition and constant returns to scale whereas the latter assumes either imperfect competition or decreasing returns to scale or both 2 the purpose of this paper is to highlight the role of the decreasing marginal return to capital assumption due to either imperfect competition or decreasing returns to scale or both in determining the effects of adjustment cost asymmetries on the sign of the response of investment to changes in uncertainty under risk neutrality for this the paper develops a simple model with a cost of adjustment mechanism general enough to consider both symmetric convexity and irreversibility as special cases one of the most important findings is the lack of robustness of the negative relationship between investment and uncertainty under asymmetric adjustment costs3 to changes in the degree of competition in fact when firms are nearly competitive the conclusion of hartman and of abel holds no matter how asymmetric adjustment costs are studying adjustment cost mechanisms has a central role in understanding the dynamics of investment and its business cycle implications but conclusive results about the sign of the instantaneous relationship between uncertainty and investment should not be department of economics columbia university new york ny 10027 i am grateful to giuseppe bertola prajit dutta glen hubbard anil kashyap richard lyons and the referees for their useful comments 1the financial literature on investment has considered risk aversion through a premium in the discount rate determined by the capm capital asset pricing model intertemporal capm or consumption capm however often this discount rate is left unchanged when studying the response of investment to uncertainty changes e g pindyck 1988 pp 974 5 thereby omitting the effect of changes in uncertainty on investment due to risk aversion and incomplete markets 2in the typical version of the irreversible investment problem there is no cost of upward adjustments thus imperfect competition and or decreasing returns to scale are required to bound the size of the firm 3in this paper asymmetric adjustment cost refers to the case in which it is more expensive to adjust downward than upward certainly the opposite case is a trivial extension of the case studied in this paper

heterogeneity under competition a standard prediction of neoclassical microeconomics is that with perfect competition free entry and atomistic firms producing a homogeneous product equilibrium finds all firms employing that technology which has minimum average cost that competition drives out inefficient producers and reduces heterogeneity within industries is consequently a commonplace rule of thumb in economic thinking this paper demonstrates that demand uncertainty is sufficient to produce heterogeneity in the equilibrium employment of production technologies and to permit the coexistence of producers exhibiting different minimum average costs this heterogeneity is ubiquitous because the conditions for its presence are not stringent

time to build and fluctuations in bulk shipping abstract this paper explores the nature of fluctuations in world bulk shipping by quantifying the impact of time to build and demand uncertainty on investment and prices we examine the impact of both construction lags and their lengthening in periods of high investment activity by constructing a dynamic model of ship entry and exit a rich dataset of secondhand ship sales allows for a new estimation strategy resale prices provide direct information on value functions and allow their nonparametric estimation we find that moving from time varying to constant to no time to build reduces prices while significantly increasing both the level and volatility of investment jel g31 l11 l62 l92

the political foundations of post communist regimes marketization agrarian legacies or international influences this article explores the causes of differing post communist regime transitions in eastern europe and the former soviet union emphasizing the increasingly prominent thesis that economic liberalization promotes political democratization we explore this argument in light of findings from other regions that have emphasized modernization agrarian class structure and international influences our results are based on a multilevel design strategy first analyzing data on 26 post communist countries over a 7 to 9 year period using time series cross sectional methods and then turning to a comparative analysis of four purposively selected cases to explore the causal mechanisms implied but not tested in the quantitative analysis our results suggest that faith in economic liberalization as a cause of democratization may be misplaced however there is support for the notion that large agrarian sectors are unfavorable to democratic development whereas positive democratic conditionality from outside agents can p

investment decisions in manufacturing assessing the effects of real oil prices and their uncertainty summary we investigate the effects of real oil prices and their uncertainty on investment decisions making use of plant level data we estimate dynamic discrete choice models that allow modeling investment inaction under different assumptions related to initial conditions and unobserved heterogeneity we find that increases in real oil price changes and in real oil price uncertainty significantly reduce the likelihood of investment action in line with the predictions of irreversible investment theory we also document that investment decisions exhibit strong pure state dependence and are also significantly affected by initial conditions copyright 2012 john wiley sons ltd

an exact solution for the investment and value of a firm facing uncertainty adjustment costs and irreversibility this paper derives closed form solutions for the investment and value of a competitive firm with a constant returns to scale production function and convex costs of adjustment solutions are derived for the case of irreversible investment as well as for reversible investment optimal investment is a non decreasing function of q the shadow value of capital relative to the case of reversible investment the

aggregate imports and expenditure components in the uk an empirical analysis this paper examines the long run relationship between uk aggregate imports and the macroeconomic components of final expenditure using the johansen multivariate cointegration analysis it is found that there are significant differences between the long run elasticities of import demand with respect to the different components of final expenditure over the period 1972 to 1990 an error correction model is proposed for short run forecasting of uk aggregate imports the short run model appears to track the data well

on the diffusion of new technology a game theoretic approach this paper is an attempt at a rigorous albeit not exceedingly general analysis of the diffusion of new technology in particular consider an industry composed of two firms each using the current best practice technology the firms are assumed to be operating at nash equilibrium output levels generating a market price given demand and profit allocations when a cost reducing innovation is announced each firm must determine when if ever to adopt it based in part upon the discounted cost of implementing the new technology and in part upon the behavior of the rival firm if either firm adopts before the other it can expect to make substantial profits at the expense of the other firm on the other hand the discounted sum of purchase price and adjustment costs may decline with the lengthening of the adjustment period as various quasi fixed factors become more easily variable therefore although waiting costs the firm more in terms of foregone profits it may save money on the cost of purchasing the new technology thus the firm must weigh the costs and benefits of delaying adoption as well as take account of its rival s strategic behavior

preemption and rent equalization in the adoption of new technology we study the adoption of a new technology to illustrate the effects of preemption in games of timing we show that the threat of preemption equalizes rents in a duopoly but that this result does not extend to the general oligopoly game if the gain to preemption is sufficiently small then the optimal symmetric outcome which involves late adoption is an equilibrium this contrasts with reinganum s result that in precommitment equilibria there must be diffusion we develop a new and richer formalism for modeling games of timing which permits a continuoustime representation of the limit of discrete time mixed strategy equilibria

twin deficit or twin divergence fiscal policy current account and real exchange rate in the u s abstract in spite of concerns about twin deficits fiscal and the current account deficits for the united states economy empirical evidence suggests that twin divergence is a more usual feature of the historical data i e when fiscal accounts worsen the current account improves and vice versa this paper empirically studies the effects of fiscal policy government budget deficit shocks on the current account and the real exchange rate during the flexible exchange rate regime period based on var vector auto regression models we identified exogenous fiscal policy shocks after controlling for business cycle effects on fiscal balances in contrast to the predictions of most theoretical models the u s results suggest that an expansionary fiscal policy shock or a government budget deficit shock improve the current account and depreciate the real exchange rate increases in private savings and declines in investment contribute to the current account improvement while a nominal exchange rate depreciation as opposed to a relative price level change is mainly responsible for the real exchange rate depreciation the twin divergence of fiscal balances and current account balances is also explained by the prevalence of output shocks i e output shocks more than fiscal shocks appear to drive the co movements of the current account and the fiscal balance

import demand in heterogeneous panel data with cross sectional dependence we investigate the long run income and price elasticity of import demand functions with a heterogeneous unbalanced panel of 34 countries over the period 1985 q1 2018 q3 to estimate world elasticit

optimal investment with lumpy costs abstract in this paper we analyze a continuous time model of investment with uncertainty irreversibility and a broad class of lumpy adjustment costs we show that the two components of the optimal investment strategy the investment trigger and the investment increment can be found sequentially and that the optimal investment increment maximizes a closed form function solving the model numerically we find that adding a relatively small amount of variable adjustment costs often leads firms to invest in much smaller increments we derive a measure of user cost that incorporates lumpy investment and use it to show that as firms invest in bigger increments the investment trigger increases as well

heterogeneous firms and the organization of production firms in the same industry exhibit systematic differences in the organization of production and the structure of employment entrepreneurial ability is the specific scarce input that limits the size of a firm this input must be allocated to two activities coordinating production and monitoring workers able entrepreneurs can convert calendar time into larger supplies of coordinating effort that enable them to assemble large firms greater ability implies a higher shadow price of time which increases the implicit costs of monitoring a dispersion of entrepreneurial abilities generates an equilibrium size distribution of firms differences in monitoring costs affect the choice of worker productivities the design of products and the organization of production the monitoring cost hypothesis advanced in this paper goes a long way in explaining the equilibrium of an industry containing heterogeneous firms that differ in size and behavior

investment irreversibility and financing constraints evidence from a panel of transition economies abstract focusing on a panel of unlisted firms from transition economies we observe that only firms facing low irreversibility exhibit high and significant investment cash flow sensitivities our findings provide a new explanation for why some financially constrained firms may exhibit low sensitivities

on the real effects of inflation and inflation uncertainty in mexico we estimate an augmented multivariate garch m model of inflation and output growth for mexico at business cycle frequencies the main findings are 1 inflation uncertainty has a negative and significant effect on growth 2 once the effect of inflation uncertainty is accounted for lagged inflation does not have a direct negative effect on output growth 3 however as predicted by friedman and ball higher average inflation raises inflation uncertainty and the overall net effect of average inflation on output growth in mexico is negative that is average inflation is harmful to mexican growth due to its impact on inflation uncertainty 4 the mexican presidential election cycle significantly raises inflation uncertainty both during the year of the election and the year following the election which has correspondingly negative effects on output growth

twin deficits squaring theory evidence and common sense in this paper we reconsider the twin deficit hypothesis that fiscal shocks generating budget deficits also worsen external trade both from a theoretical point of view and by analyzing data for australia canada the uk and the us first we assess the joint dynamics of budget and trade deficits along the business cycle uncovering a strikingly recurrent s shaped relation between the two the correlation is actually negative suggesting twin divergence this observation however cannot rule out the possibility that government spending expansions and or tax cuts may cause trade deficits as the overall correlation is likely to be dominated by cyclical factors second we reconsider the transmission of government spending in a standard two country two good model we find that openness and the persistence of fiscal shocks are major determinants of the magnitude or even sign of the response of the trade balance to fiscal shocks for a given persistence of the fiscal shock the closer an economy the larger the crowding out effect on investment the lower the deterioration of the trade balance third we take this insight to the data investigating the transmission of fiscal shocks in a var framework in the four countries in our sample our empirical findings tend to support our view in the us and australia which are relatively less open than canada and the uk and where government spending shocks are less persistent we find that the external impact of fiscal policy is rather limited instead private investment responds substantially the reverse is true for canada and the uk these findings confirm and put into perspective earlier results whereas fiscal expansions in the us are found to have on average a negligible effect on the country s trade balance however we emphasize that these results are consistent with a call for a us fiscal retrenchment to address global imbalances the impact of budget cuts on the us external trade is muted by their positive effect on domestic investment strengthening the us ability to generate resources against future interest and debt repayment
