acquisitions and investment we derive a simple theoretical framework in which acquisitions are treated as an alternative way of obtaining capital goods our framework predicts that both investment and acquisitions are positively related to a firm s shadow value of capital we transform our theoretical specification into an econometric model which we then estimate using a long panel data set spanning 503 us firms over 15 consecutive years our results indicate that an increase in the shadow value of capital has approximately the same proportionate effect on the level of acquisitions as it does on investment this result proves to be robust to a variety of alternative specifications recent years have witnessed a dramatic increase in the number of corporate takeovers this tide of activity raises a number of questions about the causes and consequences of acquisitions what effects do takeovers have on research and development spending do takeovers reduce employment how important are tax considerations in motivating acquisitions do management objectives and or the availability of free cash flow play a role in acquisitions although these questions have been addressed in previous research no specific optimizing model has been put forward to explain the fundamental nature of the acquisition decision in this paper we propose such a model when a firm makes an acquisition it obtains assets in this way acquisitions and investment are similar activities which one might expect to be guided at least to a substantial extent by similar economic principles in this paper we specify and estimate a simple model that explicitly links a firm s acquisition activities to its investment choices the only unusual feature of this model is that these goods can be either purchased directly investment or obtained by taking over another firm acquisitions our model is based on the firm s intertemporal optimization problem under what are with this one exception standard assumptions our specification yields a pair of equations in which a firm s choices regarding acquisitions and investment are jointly determined and are influenced by the shadow value of capital as in many models of investment we assume that firms face convex costs of adjusting their capital stocks consequently the shadow value of capital may exceed its replacement cost firms for which the shadow value of capital is high relative to its purchase price will have an incentive to make relatively large capital purchases in relation to their existing capital stock under standard assumptions the shadow value of capital is reflected in the firm s stock market

inequality and the impact of growth on poverty comparative evidence for sub saharan africa abstract this study explores the extent to which inequality affects the impact of income growth on the rates of poverty changes in sub saharan africa ssa compared to non ssa based on an unbalanced panel of 86 countries over 1977 2004 for all three measures of poverty headcount gap and squared gap the impact of gdp growth on poverty reduction is a decreasing function of initial inequality the impacts are similar in direction for ssa and non ssa so that within both regions there are considerable disparities in the responsiveness of poverty to income growth depending on inequality nevertheless the income growth elasticity is substantially less for ssa implying relatively small poverty reduction response to growth

do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods dauth w hujer r and wolf k do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods regional studies the effect of active labour market policies on all job seekers in a region is assessed using the variation in the participation in these programmes across regions over time the starting point is an augmented regional matching function which is extended by allowing for a heterogeneous search effectiveness parameter for current participants and job seekers who finished a measure recently a spatial dynamic panel data model is estimated by using a quasi ml estimation procedure it is found that job schemes in the non profit sector wage subsidies and advancement of apprenticeships significantly increase the regional number of matches

decentralisation of active labour market policy the case of swedish local employment service committees decentralisation of decision making in active labour market policy makes it possible to use local information to the fullest but may also impinge on the fulfilment of national objectives as suggested by principal agent theory the purpose of this study is to examine the effects of a swedish pilot programme in 1996 which strengthened the role of the local authorities in labour market policy in parts of the country survey evidence suggests a non negligible divergence between the objectives of the municipality representatives and the central government s goals regarding programme effects our econometric findings do not indicate any increase in geographical lock in of the unemployed but decentralisation seems to spur local initiatives in the form of labour market programmes organised by the municipalities in addition targeting on outsiders is to some extent more common in municipal projects than in others

international comovement of economic fluctuations a spatial analysis summary we consider the comovement of economic volatility across multiple countries using spatial models with data from 187 countries over the period of 1960 2007 we find a strong spatial comovement of economic volatility more interestingly the effect of geographical proximity on economic volatility comovement is strongest during the period of international shocks 1973 86 but almost disappears over the globalization era 1987 2007 by way of contrast the influence of trade relations in determining the comovement of economic volatility is significant over 1987 2007

borders and business cycles abstract we document that business cycles of u s census regions are substantially more synchronized than those of european countries data from regions within european countries confirm a european border effect within country correlations are substantially larger than cross country correlations these results continue to hold after controlling for exogenous factors such as distance and size we consider the role of four factors that have received attention in the debate about emu sectoral specialization the level of trade monetary policy and fiscal policy we find that the lower level of trade between european countries explains most of the observed border effect

do entrepreneurs create jobs many countries support the creation of new firms such policy is based on the presumption that the total number of jobs increases when a person moves from unemployment or regular employment to self employment in this paper the link between self employment and overall employment is analyzed the empirical analysis based on panel data of swedish counties from 1976 1995 pays particular attention to simultaneity issues the results suggest that self employment may have a significant positive effect on overall employment

business cycle comovement in the g 7 common shocks or common transmission mechanisms what are the sources of macroeconomic comovement among g 7 countries two main candidate explanations may be singled out common shocks and common transmission mechanisms in the article it is shown that they are complementary rather than alternative explanations by means of a large scale factor vector autoregressive fvar model allowing for full economic and statistical identification of all global and idiosyncratic shocks it is found that both common disturbances and common transmission mechanisms of global and country specific shocks account for business cycle comovement in the g 7 countries moreover spillover effects of foreign idiosyncratic disturbances seem to be a less important factor than the common transmission of global or domestic shocks in the determination of international macro economic comovements

functional equivalence between intertemporal and multisectoral investment adjustment costs abstract two types of adjustment cost specifications coexist in macroeconomic models with investment intertemporal adjustment costs which involve a nonlinear substitution between capital and investment in capital accumulation and multisectoral costs which are captured by a nonlinear transformation between consumption and investment this paper demonstrates a functional equivalence between these two specifications one surprising result is that an increase in multisectoral adjustment costs can be equivalent to a decrease in intertemporal adjustment costs depending upon the size of the intertemporal costs we then observe that the functional equivalence implies a problem in identifying the two types of adjustment costs and show ways to solve the problem

a bottleneck capital model of development abstract a simple augmentation of the ramsey cass koopmans growth model allows it to match observed transitions by initially poor economies a high convexity installation cost directly dampens investment demand for a first capital input the resulting scarcity acts as a bottleneck strongly dampening demand for investment in a complementary capital input as well the match to observed transitions holds both for narrow and broad interpretations of capital in either case the bottleneck capital s share of factor income need not be large

international evidence on the historical properties of business cycles we contrast properties of real quantities with those of price levels and stocks of money for ten countries over the last century although the magnitude of output fluctuations has varied across countries and periods relations among real quantities have been remarkably uniform properties of price levels however exhibit striking differences between periods inflation rates are more persistent after world war ii than before and price level fluctuations are typically procyclical before world war ii and countercyclical afterward fluctuations in money are less highly correlated with output in the postwar period but are no more persistent than in earlier periods jel e32 e31

on the sources of business cycles in the g 7 abstract this paper examines sources of cyclical movements in output inflation and the term structure of interest rates in the g 7 it employs a novel identification approach which uses the sign of the theoretical cross correlation function in response to shocks to catalog orthogonal disturbances we find that demand shocks are the dominant source of output and inflation fluctuations in several of the g 7 countries the proportion of term structure variability explained by different structural sources does not depend on the horizon apart from the us and canada structural shocks are nearly uncorrelated across countries

job matching temporary public employment and equilibrium unemployment abstract the paper presents a theoretical analysis of the macroeconomics effects of temporary public employment programs relief jobs the framework is a matching model where wages are determined by nash bargains between individual firms and workers public employment programs have a direct job placement effect which tends to reduce unemployment there is also an effect on wage pressure the direction of this effect hinges on whether the programs are aimed at increasing unemployment outflow of reducing unemployment inflow a policy targeted at unemployment outflow has in general ambiguous effects on equilibrium unemployment since the job placement effect and the wage effect work in opposite directions by contrast a policy targeted at unemployment inflow will always reduce unemployment since the job placement effect is reinforced by the induced wage moderation

does active labour market policy increase employment theoretical considerations and some empirical evidence from sweden does active labour market policy increase employment theoretical considerations and some empirical evidence from sweden

real wage determination and labour market policies the swedish experience it is a common view that labor market programs reduce unemployment and restrain wages by increasing the competition for jobs the swedish case is often advanced as a blueprint to follow this article questions the conventional wisdom on the swedish labor market policies it finds empirical evidence in favor of the hypothesis that job creation and training programs weaken the incentives for wage restraint as a consequence it appears likely that labor market programs have strong crowding out effects on regular employment copyright 1991 by royal economic society

effectiveness of active labor market tools in conditional cash transfers programs evidence for argentina summary this paper examines the impact of the program seguro de capacitacion y empleo sce implemented to provide support in skills upgrading job seeking and job placement to eligible beneficiaries of the argentinian conditional cash transfer program plan jefes the sce is an example of a growing trend observed in latin america where labor activation components have been increasingly included into cash transfers programs to support beneficiaries in finding more stable income opportunities despite this growing trend not enough is known regarding the effectiveness of these components especially on job quality in this context this paper sheds light on whether the provision of a comprehensive package of active labor market measures contributes to a successful labor market integration of cash transfers beneficiaries taking advantage of the panel structure of the permanent household survey and exploiting the time variation in the assignment of the program as identification strategy we apply difference in difference estimators to measure the impact on a number of labor market indicators we find that the program affects positively the job quality of participants by increasing the probability of having a formal job and raising hourly wages moreover the intervention is associated with a lower probability of having a low paid job and working an excessive number of hours these effects are however not homogeneous across all groups of participants while the program is more successful among the younger beneficiaries it does not contribute to an improvement in the labor market conditions of female beneficiaries who in fact are the majority of sce participants our results suggest that reducing dependency on monetary transfers through programs such as the sce that are rich in activation components is beneficial for participants labor market trajectories and therefore it constitutes a satisfactory exit strategy to more universal cash transfer programs

the determinants of uk business cycles this paper considers the causes of post war uk business cycles using an extended stochastic growth model we construct estimates of productivity and preference shocks both of which are highly persistent volatile and potentially capable of explaining uk business cycles we find the productivity term is the dominant explanation of uk output fluctuations but our estimated preference shift is crucial in understanding employment movements a variety of granger causality tests establish whether these productivity and preference terms are unpredictable and so can be potentially considered as the cause of uk business cycles or whether they are themselves granger caused by other variables the aim of business cycle theory is to identify the causes of business cycles and outline the various propagation mechanisms through which these produce cyclical fluctuations the purpose of this paper is to study the former using uk data we investigate the main sources of uk post war business cycles our aim in doing so is to discriminate between competing theories of the business cycle as well as to increase our understanding of particular episodes of uk post war economic history to achieve this aim we focus on two fundamental sources of business cycle fluctuations productivity shocks and a preference shift or more generally a supply and demand shock we choose these because i they can be easily calculated using only published data avoiding the need for any econometric identification assumptions ii they represent the simplest extension to the neoclassical stochastic growth model which can explain observed uk business cycle patterns they therefore form a natural benchmark with which to assess prescott s 1986 claim that this model can account for both growth and business cycles however while our main focus is on these two shocks our methodology is broad enough to allow for a wide range of potential causes of uk business cycles in section 1 of the paper we outline some stylised facts of the uk business cycle and motivate more rigorously our focus on productivity and preference shocks in section 2 we provide estimates of these shocks discuss their univariate properties and examine their correlation with key business cycle variables we find both shocks to be very volatile and persistent with the productivity variable accounting for a large proportion of output fluctuations and preference shifts more important in explaining employment movements simulations show that in combination with a neoclassical growth model these shocks are capable of matching uk business cycles however if

how does globalization affect the synchronization of business cycles this paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries the results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles the evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries one striking result is that on average cross country consumption correlations have not increased in the 1990s precisely when financial integration would have been expected to result in better risk sharing opportunities especially for developing countries this abstract was borrowed from another version of this item

dynamic effects of permanent and temporary tax policies in a q model of investment abstract this paper incorporates the tax policy analysis of hall and jorgenson into a dynamic optimizing model with adjustment costs to develop a q model of investment this framework is particularly useful for analyzing the dynamic effects on investment of permanent and temporary changes in tax policy it is shown that contrary to the conventional intertemporal substitution argument a temporary investment tax credit need not be nore expansionary than a permanent investment tax credit the role of depreciation allowances in determining the dynamic response of investment to temporary changes in the tax rate is also investigated

roads to prosperity assessing the link between public capital and productivity does the positive correlation between infrastructure and productivity reflect causation if so in which direction the author finds that when growth in roads the largest component of infrastructure changes productivity growth changes disproportionately in u s industries with more vehicles that vehicle intensive industries benefit more from road building suggests that roads are productive at the margin however road investments do not appear unusually productive intuitively the interstate system was highly productive but a second one would not be road building thus explains much of the productivity slowdown through a one time unrepeatable productivity boost in the 1950s and 1960s

q and the tax bias theory abstract a growing body of literature analyzes the variation in q the ratio of financial market value to asset current replacement cost and makes inferences about attributes such as monopoly power profitability managerial performance etc these studies ignore potential biases embedded in q that result from non neutral tax policies this study examines the association between q and tax biases and establishes that differences in accumulated depreciation tax shields explain significant variation in q the implication that q should be adjusted for tax biases before use in empirical research is examined further adjusting q for tax biases at least with the factors herein leads only to minor changes in econometric analyses

determinants of business cycle comovement a robust analysis abstract this paper investigates the determinants of business cycle comovement between countries our dataset includes over 100 countries both developed and developing we search for variables that are robust in explaining comovement using the approach of leamer amer econom rev 73 1983 31 variables considered are i bilateral trade between countries ii total trade in each country iii sectoral structure iv similarity in export and import baskets v factor endowments and vi gravity variables we find that bilateral trade is robust however two variables that the literature has argued are important for business cycles industrial structure and currency unions are found not to be robust

institutional causes macroeconomic symptoms volatility crises and growth countries that have pursued distortionary macroeconomic policies including high inflation large budget deficits and misaligned exchange rates appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period does this reflect the causal effect of these macroeconomic policies on economic outcomes one reason to suspect that the answer may be no is that countries pursuing poor macroeconomic policies also have weak institutions including political institutions that do not constrain politicians and political elites ineffective enforcement of property rights for investors widespread corruption and a high degree of political instability this paper documents that countries that inherited more extractive institutions from their colonial past were more likely to experience high volatility and economic crises during the postwar period more specifically societies where european colonists faced high mortality rates more than 100 years ago are much more volatile and prone to crises based on our previous work we interpret this relationship as due to the causal effect of institutions on economic outcomes europeans did not settle and were more likely to set up extractive institutions in areas where they faced high mortality once we control for the effect of institutions macroeconomic policies appear to have only a minor impact on volatility and crises this suggests that distortionary macroeconomic policies are more likely to be symptoms of underlying institutional problems rather than the main causes of economic

nonlinear response of firm investment to q abstract abel and eberly 1994 study optimal investment behavior in the presence of flow fixed costs proportional costs and convex costs a clear prediction is that investment will alternate between regimes of insensitivity and responsiveness to q separated by unknown threshold levels of q at the firm level we find evidence for different regimes of sensitivity to q but not for a regime of zero sensitivity our finding that investment has a nonlinear relationship to q is important because it implies an elasticity of aggregate investment to q and fundamentals that is high and variable over time

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

the q theory of investment with many capital goods the q theory of investment which relates investment to the ratio of market to replacement value of capital has attracted considerable attention in a recent series of papers for instance a q variable has been used as an independent variable in empirical investment equations estimated by george von furstenberg 1977 von furstenberg et al 1980 burton malkiel et al 1979 and others these papers however leave somewhat unclear the theoretical rationale for using q as an investment determinant this has motivated work by hiroshi yoshikawa 1980 lawrence summers 1981 michael salinger and summers 1981 and fumio hayashi 1982 who show that under certain conditions the rate of investment of a sharevalue maximizing firm is indeed a function of q this is an important result because it shows that investment equations with q an independent variable are not ad hoc constructions rather they are grounded in a theory of the firm with an appealing behavioral hypothesis viz value maximization an important assumption underlying this research is that capital can be treated as a homogeneous good of course this is an extremely common assumption in the analysis of investment and is not particularly more bothersome in the q theory context than elsewhere nonetheless there are certain situations where it may be desirable or even essential to be able to study investment disaggregated by type of capital good thus the purpose of this paper is to examine whether and how the q theory can be extended to this more general case 1 intuitively one would expect some difficulty with the q theory in the many capitalgood context as already noted by james tobin and william brainard 1977 p 243 and by salinger and summers p 12 one way to see why is to recall the tobin brainard distinction between marginal and average q as hayashi writes

the effectiveness of qualification measures for employed workers an evaluation study for saxony this article investigates whether and to what extent employment policy measures co financed by the european social fund in germany meet their objective specifically it is analysed whether qualification programs for employed workers in the german state of saxony were effective in terms of employment protection to this end a control function approach is implemented which utilizes a unique firm level dataset this model explicitly accounts for unobserved heterogeneity between participating and nonparticipating companies by modelling the participation decision process our results suggest a positive effect of program participation however this positive treatment effect varies considerably across different sub groups of the treatment as well as the comparison group

financial openness and business cycle volatility abstract this paper discusses whether the integration of international financial markets affects business cycle volatility in the framework of a new open economy macro model we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock empirical evidence supports this conclusion our results also show that the link between business cycle volatility and financial openness has not been stable over time

transitional dynamics and economic growth in the neoclassical model neoclassical transitional dynamics are a central element of standard macroeconomic theory quantitative experiments with the fixed savings rate models of the 1960s showed lengthy transitions thus potentially rationalizing sustained differences in growth rates across countries the authors investigate quantitative transitional dynamics in various neoclassical models with intertemporally optimizing households lengthy transitions occur only with very low intertemporal substitution generally when one tries to explain sustained economic growth with transitional dynamics there are extremely counterfactual implications these result from the fact that implied marginal products are extraordinarily high in the early stages of development copyright 1993 by american economic association

fdi in space spatial autoregressive relationships in foreign direct investment abstract there are a number of theoretical reasons why foreign direct investment fdi into a host country may depend on the fdi in proximate countries such spatial interdependence has been largely ignored by the empirical fdi literature with only a couple recent papers accounting for such issues in their estimation this paper conducts a general examination of spatial interactions in empirical fdi models using data on us outbound fdi activity we find that estimated relationships of traditional determinants of fdi are surprisingly robust to inclusion of terms to capture spatial interdependence even though such interdependence is estimated to be significant however we find that both the traditional determinants of fdi and the estimated spatial interdependence are quite sensitive to the sample of countries one examines

the relation between firm growth and q with multiple capital goods theory and evidence from panel data on japanese firms we derive from a model of investment with multiple capital goods a one to one relation between the growth rate of the capital aggregate and the stock market based q we estimate the growth q relation using a panel of japanese manufacturing firms taking into account the endogeneity of q identification is achieved by combining the theoretical structure of the q model and an assumed serial correlation structure of the technology shock which is the error term in the growth q equation for early years of our sample cash flow has significant explanatory power over and above q the significance of cash flow disappears for more recent years for the heavy industry when japanese capital markets was liberalized the estimated q coefficient implies that the adjustment cost is less than a half of gross profits net of the adjustment cost

foreign direct investment in china a spatial econometric study foreign direct investment fdi began to flow into china with advent of reforms in 1978 following a period of relatively slow growth fdi inflows to china picked up after 1990 as china surpassed every other nation but the united states in attracting foreign investment in particular coastal regions of china have received the bulk of fdi inflows to the country in this paper we use province level data to explain the pattern of fdi location across china we build upon previous research introducing new potential determinants using more recent fdi data and incorporating spatial econometric techniques in doing so we test for potential econometric problems arising from the spatial pattern of the data and correct for them by running more appropriate models we find that economic size labor productivity and coastal location attract fdi while higher wages and illiteracy rates deter it the transportation infrastructure variables we try are not found to have statistically significant relationships with the level of fdi inflows across provinces this abstract was borrowed from another version of this item

a simple time series test of endogenous vs exogenous growth models an application to the united states this paper presents evidence supporting endogenous growth models that emphasize public structural capital the authors apply a simple test of endogenous vs exogenous growth models in exogenous growth economies temporary innovations to policy variables lead only to temporary changes in gnp levels while in endogenous growth economies the innovations can lead to permanent changes in gnp levels of the seven u s policy variables they examine only non military equipment capital and non military structural capital have a statistically and economically significant effect upon long run gnp levels further estimation suggests that the non military equipment capital result is not robust and that several disaggregate components of structural capital contribute significantly copyright 1996 by mit press

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

liability management of financial intermediaries in a dynamic and uncertain perspective this paper examines the effect of rate uncertainty first for the loan rate alone next for both asset and liability rates on the liability funding decisions of a risk neutral intermediary in this model a la pindyck rates evolve according to stochastic processes convex adjustment costs arise from the dichotomy of existing core deposits and new savings balances and the intermediary s cash flow is embedded into capital market theory then we show that the stationary equilibrium obtains at the intersection of the locus of no change in deposit holdings with the isocline of zero change in savings balances loan rate uncertainty alone shifts the savings isocline outward when marginal adjustment costs are rising at an increasing rate but when asset and liability rates are uncertain their impact on the mean intermediation spread core deposit holdings and adjustment costs depends on whether they are correlated or not

understanding the evolution of world business cycles abstract this paper studies the changes in world business cycles during the period 1960 2003 we employ a bayesian dynamic latent factor model to estimate common and country specific components in the main macroeconomic aggregates output consumption and investment of the g 7 countries we then quantify the relative importance of the common and country components in explaining comovement in each observable aggregate over three distinct time periods the bretton woods bw period 1960 1 1972 2 the period of common shocks 1972 3 1986 2 and the globalization period 1986 3 2003 4 the results indicate that the common g 7 factor explains on average a larger fraction of output consumption and investment volatility in the globalization period than it does in the bw period

trade interdependence and the international business cycle a stochastic general equilibrium model of the world economy is developed to analyze the contribution of trade interdependence to international business cycles we test some of the implications of the model using data from ten major industrial countries and a variety of detrending techniques to calculate the cyclical component of output we find that the significance of trade in the transmission of economic disturbances across countries is not robust to the choice of the detrending method in general the role of trade interdependence is moderate and seem to have been stronger in the period before 1973

an intertemporal model of saving and investment this paper characterizes a market economy with infinitely long lived consumers and value maximizing firms which face costs of adjustment for capital the temporary equilibrium of this economy is similar to the short run equilibrium of standard macroeconomic models consumption is a function of wealth investment is related to the value of firms equilibrium between aggregate demand and aggregate supply is achieved by the endogenous adjustment of the sequence of current and future interest rates the dynamic behavior of output consumption and investment in this economy is the same as in an optimal growth model with adjustment costs the paper shows this equivalence and then uses it together with the equivalence of taxes to technological shocks to study the dynamic effects of fiscal policy

monopolistic competition and the q theory of investment abstract in this paper we analyse the implications for q models of investment of replacing the assumption of perfect competition in the output market with the assumption of monopolistic competition the structural investment equation that can be derived in this case has a richer dynamic structure than the conventional one and it contains in addition to present and future q output as an explanatory variable in the applied section we discuss the extent to which monopolistic competition helps in providing a remedy for the empirical weaknesses of q models the estimates are obtained using aggregate data for u k industrial and commercial companies for the period 1951 1979

labor market slack and the wage curve abstract the unemployment rate might not serve as an accurate measure of labor market slack when analysing countries with large scale labor market programs we replicate and extend the wage curve for east germany the results are in favor of the incorporation of such policy measures

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association

the governance of financial supervision recent developments this paper examines the evolution of financial supervision as a policy tool over the last three decades with a focus on the issues raised by the global crisis it considers a sample of advanced and emerging economies to discuss the four main questions debated in the literature and addressed in the economic policy arena the architecture of supervision the role of the central bank as supervisor the governance of supervision and financial supervision vs the internationalization of finance our survey finds that on each of these issues theory and practice do not offer clear cut answers and unambiguous optimal solutions at the same time the most promising approach is to tackle financial supervision as a principal agent problem where economics and political economy approaches must be used in combination to improve both positive and normative analyses of supervisory governance
