endogenous business cycles and systematic stabilization policy we study the effects of fiscal policy rules on the determinacy of rational expectations equilibrium in a perfectly competitive monetary model with constant returns government spending implies a distortion of the monetary steady state due to the implied taxation we show that policy rules that let the gnp share of government spending depend sufficiently negatively on increases in gnp stabilize the economy with respect to endogenous fluctuations for arbitrarily little distortion of the steady state at which stabilization occurs the rules do not involve lump sum taxation negative income taxation or exact knowledge of the economy s laissez faire steady state

mutual fund performance an analysis of quarterly portfolio holdings this article employs the 1975 84 quarterly holdings of a sample of mutual funds to construct an estimate of their gross returns this sample which is not subject to survivorship bias is used in conjunction with a sample that contains the actual net returns of the mutual funds in addition to allowing the authors to estimate the bias in measured performance that is due to the survival requirement and to estimate total transaction costs the sample is used to test for the existence of abnormal performance the tests indicate that the risk adjusted gross returns of some funds were significantly positive copyright 1989 by the university of chicago

contrarian and momentum strategies in germany two traditional methods of managing equity portfolios are investing based on price momentum and value based contrarian investing these strategies may be motivated by a behavioral theory of under and overreaction to news or by empirical research mostly for the nyse that has found persistence in price movements over short horizons and reversion to the mean over longer horizons however the apparent success of these strategies may be due to institutional factors and the mismeasurement of risk or it may result from data mining for these reasons we studied all major german companies listed on the frankfurt stock exchange for the three decades between 1961 and 1991 the dynamics of stock prices in frankfurt are remarkably similar to new york the data suggest that equity prices reflect investor forecasts of company profits that are predictably wrong

the case against intellectual property according to a common argument the presence of strong intellectualproperty rights spurs innovation which leads to higher economic growthand increasing benefits for all the argument seems coherent theestablishment of secure property rights is a fundamental pillar of a wellfunctioning market economy no economic agent exercises productiveeffort without the certainty of controlling its fruits what is true forphysical effort must be true for the intellectual one if strong propertyrights provide good incentives for the production of potatoes they mustalso provide good incentives for the production of ideas why then do we argue a case against intellectual property are wearguing that while stealing potatoes is bad stealing ideas is good weare not economic efficiency and common sense argue that ideasshould be protected and available for sale just like any other commodity but intellectual property has come to mean not only the right to ownand sell ideas but also the right to regulate their use this creates asocially inefficient monopoly and what is commonly called intellectualproperty might be better called intellectual monopoly when you buy apotato you can eat it throw it away plant it or make it into a sculpture current law allows producers of a cds and books to take this freedomaway from you when you buy a potato you can use the idea of a potatoembodied in it to make better potatoes or to invent french fries currentlaw allows producers of computer software or medical drugs to take thisfreedom away from you it is against this distorted extension ofintellectual property rights that we argue it is a long jump from the assertion that inventors deserve the fruits oftheir efforts to the conclusion that current patent and copyrightprotection are the best way of providing such reward statements such

industry momentum and sector mutual funds recent academic research has ascribed the intermediate term 3 month to 12 month momentum present in u s stock returns to an industry effect in the intermediate term strong weak industry performance is followed by continued strong weak industry performance the industry specific aspect of momentum gives rise to profitable trading strategies that use industry sector mutual funds in this study strategies of buying previous intermediate term top performing sector funds outstripped the s p 500 index over the 10 year period from may 1989 through april 1999 on a total return basis these strategies entailed greater total and systematic risk however than the index

the winner loser anomaly recent evidence from greece abstractthis article finds evidence of significant reversals in returns over the medium term in greek stocks in contrast with previous research return reversals are more pronounced for past winners suggesting that the market overreacts to a greater extent to good news these contrarian returns are particularly elevated when portfolios are formed using quartiles and during tranquil and bull markets the optimum contrarian strategy involves skipping the first 6 months of the holding period and implementing the contrarian strategy for a period of 18 months as returns exhibit continuation followed by reversal the profitability of the contrarian investment strategy is robust to adjustments for risk and seasonalities it is the tranquil times and not the crisis volatile times that generates a significant and profitable contrarian strategy the recent credit crisis and resulting stock market falls resulted in extreme movements in some greek stocks and testing of the contrarian strategy problematic especia

temporary stabilization a stochastic analysis abstract this paper develops a stochastic model of exchange rate based inflation stabilization in which agents have expectations of devaluation driven by a mixed diffusion jump process in a richer stochastic environment where a brownian motion drives the rate of devaluation and a poisson process determines the probability of devaluation we examine consumption and wealth equilibrium dynamics when a stabilization plan is implemented and contingent claims markets are unavailable we also assess the effects of exogenous shocks on consumption and welfare finally we use the proposed model to carry out a simulation experiment of the equilibrium dynamics

sectoral shocks and aggregate fluctuations abstract this paper presents a multisector dynamic general equilibrium model of business cycles with a distinctive feature aggregate fluctuations are driven by independent sectoral shocks the model hypothesizes that trade among sectors provides a strong synchronization mechanism for these shocks due to the limited but locally intense interaction that is characteristic of such input trade flows limited interaction characterized by a sparse intermediate input use matrix reduces substitution possibilities among intermediate inputs which strengthens comovement in sectoral value added and leads to a postponement of the law of large numbers in the variance of aggregate value added the chief virtue of this model is that reliance on implausible aggregate shocks is not necessary to capture the qualitative features of macroeconomic fluctuations building on horvath 1998 review of economic dynamics 1 781 808 which establishes the theoretical foundation for the relevance of limited interaction in the context of a stylized multisector model this paper specifies a more general multisector model calibrated to the us 2 digit standard industrial code economy simulations prove the model is able to match empirical reality as closely as standard one sector business cycle models without relying on aggregate shocks

production technologies in stochastic continuous time models abstract properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis very precise and intuition building results are obtained by working with models which provide closed form solutions closed form solutions are known for a large class of models some of which however have some undesirable features such as potentially negative output this paper offers closed form solutions for models which are just as tractable but do not suffer from these shortcomings

seasonalities in security returns the case of earnings announcements abstract we document a seasonal pattern in stock returns around quarterly earnings announcement dates small firms show large positive abnormal returns and a sizable increase in the variability of returns around these dates only part of the large abnormal returns can be accounted for by the tendency of firms with good news to announce early large firms show no abnormal returns around announcement dates and a much smaller increase in variability

time varying risk and long term reversals a re examination of the international evidence long term reversals ltrs have been extensively documented as existing in international markets the predictability of returns opens the question whether investors should continue to diversify across international markets such predictability also has implications for the corporate decision of where and when to raise capital this paper re examines the international evidence for long term contrarian profits using a longer time horizon than all previous studies 81 years of data from 1925 to 2005 and finds that the long term contrarian anomaly disappears when time varying conditional alphas are considered this is true even without transaction costs for the marginal trader conservative transaction costs subsume ltr profits whether returns are risk adjusted or not this suggests that benefits from actual trades on ltrs do not negate a strategy based on diversification although time varying beta has been extensively documented as ineffective in describing ltrs this paper demonstrates that it is important to control for time variation in alpha a full conditional capital asset pricing model captures the ltr premium this suggests that macroeconomic factors are important for understanding ltrs and their associated risk

fertility volatility and growth abstract empirically growth rates are negatively correlated with birth rates they are also correlated with production risk we argue that these stylized facts are related and arise jointly from the decision of how many children to have in a risky environment

path dependence endogenous innovation and growth the article presents a model of endogenous innovation and growth in which technological change is path dependent the historical pattern of technological development plays a central role in determining the pace of future technological change path dependence is explained using a distinction between fundamental and secondary knowledge the economy moves endogenously between periods of drastic and nondrastic innovation technological lock in is shown to be a special case of path dependence the model provides a rationale for cycles in technological leadership this rationale exists in equilibria with positive levels of fundamental research and in a world with no imitation

risk the financial market and macroeconomic equilibrium growing recognition of the importance of stock market phenomena to the real economy underscores the need for models linking exogenous uncertainty asset market performance and the rest of the economy in an optimizing framework without certainty equivalence this paper constructs a three agent model with continuous time stochastic variables uncertain private production and government expenditure and forward looking rational agents the growth rate of output physical capital accumulation financial asset returns and uncertain inflation are determined as functions of the exogenous uncertainty in the economy analysis of the model finds that increased risk associated with government policy often reverses in an explainable way the conventional comparative static predictions of nonstochastic macro models

nonstationary expected returns abstract recent evidence reveals significant negative serial correlation in aggregate market wide stock returns we extend this result to relative market adjusted returns demonstrating negative serial correlation in five year returns we then test two competing explanations 1 market mispricing and 2 changing expected returns in an efficient market the tests are conducted using the capital asset pricing model to estimate relative returns the evidence suggests that negative serial correlation in relative returns is due almost entirely to variation in relative risks and therefore expected relative returns through time we document substantial relative risk shifts particularly for extreme performing stocks

bank foreign lending mandatory disclosure rules and the reaction of bank stock prices to the mexican debt crisis this paper examines the effects of the mexican debt mora torium in august 1982 on bank valuation the mexican default resulted in the passage of regulations requiring public disclosure of bank fo reign lending exposure the authors find that even in the absence of public disclosure regulations investors were able to discriminate a mong banks with different levels of exposure copyright 1987 by the university of chicago

money and endogenous growth the ramsey romer model of endogenous growth is extended to allow for holdings of real money balances and government debt as well as capital and for non interconnected generations of households tax financed increases in government consumption and debt depress growth prospects and boost inflation as long as a positive birth rate ensures that future taxes are shouldered by future yet unborn generations debt financed increases in government consumption depress growth and boost inflation even more money financed increases in government consumption depress growth less but increase inflation by more giving subsidies through an increase in monetary growth is non neutral since this increases real growth and thus inflation increases by a lesser amount than monetary growth bond financed increases in monetary growth lead to a larger increase in real growth and a smaller increase in inflation if there are cost adjustment for investment cuts in monetary growth and increases in government debt and government consumption induce an increase in the real interest rate copyright 1994 by ohio state university press

on sustained growth under uncertainty we analyze a stochastic one sector model of economic growth and investigate the conditions under which long run growth occurs almost surely in contrast to the deterministic version of the model the utility function plays a crucial role in determining the long run behavior of output the central purpose of theories of economic growth is to understand the factors behind long run growth of economies and to explain differences in growth performances of economies in terms of fundamental endowments and choices a wide class of endogenous growth models has been specified in the last decade and they have explored a large array of possible explanatory variables for the differences in observed growth rates between countries with some notable exceptions most of these models are deterministic and therefore ignore the fundamental uncertainties which affect productivity and cause diversity between growth of nations the exceptions which include real business cycle models that examine the consequence of productivity shocks in endogenous growth frameworks use specific utility and production functions drawn from the log linear family see among others king et al 1988 king and rebelo 1988 de hek 1999 jones et al 1999 a general analysis of the phenomenon of sustained growth in economies subject to technological shocks is not yet available and the kind of conditions needed to guarantee sustained stochastic growth are not well understood in this article we address this issue in the simple framework of a stochastic one sector convex growth model when the technology is globally productive in the sense that marginal productivity of investment is bounded above one output and consumption flows can grow indefinitely i e long run growth is feasible whether such growth actually occurs depends on the intertemporal preference structure 2 in the deterministic version of this model this problem was first discussed by gale and sutherland 1968 who extended the classical optimal growth analysis to the case of such a productive technology more recently jones and manuelli 1990 have rigorously characterized the possibility of sustained long run growth in a variant of the one sector deterministic growth model see also rebelo 1991 3 the main result is that long run growth

market reaction to the thrift bailout abstract this paper examines the share price reaction of depository institutions to the financial institutions reform recovery and enforcement act firrea passed august 1989 we find a favorable share price response for thrifts which could be attributed to enhanced depositor confidence reduced risk premiums on deposits reduced agency costs or reduced loan losses among other reasons however the effects of firrea on commercial banks were negligible an intra industry analysis revealed that the variation in share price responses could not be explained by cross sectional differences in thrift capital levels

macroeconomic policies growth and welfare in a stochastic economy an integrated stochastic equilibrium growth model is constructed and directed to various questions pertaining to monetary and tax policy two main issues addressed include 1 the tradeoff between the rate of capital accumulation and inflation in a stochastic environment and 2 economic welfare and optimal policy making the key result is that policy variables impact on welfare through their effect on the after tax nominal interest rate which therefore serves as an intermediate policy target the welfare maximizing interest rate target is derived and the author discusses its attainment through appropriate monetary and tax policies tradeoffs between policy instruments are also addressed copyright 1993 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

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

on endogenous growth under uncertainty this paper incorporates uncertainty in two distinct models of endogenous growth in both models the representative agent is uncertain about the productivity of knowledge creation as represented by a probability measure over the relevant parameter the main purpose of this paper is to analyze the effects of risk or volatility in productivity of knowledge creation on the decision variables and the expected long run growth rate both the first and the second models may explain part of the observed negative link between volatility and growth

consequences of debt policy in a stochastically growing monetary economy the effects of open market operations and long versus short bond financing on risk in financial markets in a stochastically growing economy are studied an increase in short bonds resulting from exchanging long bonds increases the riskiness of long bonds and raises their real rate of return an open market purchase of either long or short bonds raises the price of long bonds and lowers their risk and real return however debt policy adjustments that affect the real return to long bonds do not affect real investment or growth so that overall the welfare consequences of debt policy are neutral copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

long term market overreaction the effect of low priced stocks conrad and kaul 1993 report that most of de bondt and thaler s 1985 long term overreaction findings can be attributed to a combination of bid ask effects when monthly cumulative average returns cars are used and price rather than prior returns in direct tests we find little difference in test period returns whether cars or buy and hold returns are used and that price has little predictive ability in cross sectional regressions the difference in findings between this study and conrad and kaul s is primarily due to their statistical methodology they confound cross sectional patterns and aggregate time series mean reversion and introduce a survivor bias their procedures increase the influence of price at the expense of prior returns

increasing returns and increasing rates of growth romer 1986b documented that industrial economies have tended to have growth rates that increase over time having explained why the aggregate growth models of ramsey 1928 cass 1965 and koopmans 1965 fail to account for this observation romer proposed an alternative view of long run prospects for growth combining three elements externalities increasing returns in the production of output and decreasing returns in the production of new knowledge he constructed an equilibrium model of growth in his infinite horizon continuous time analysis qualitative conclusions were reached using the geometry of the phase plane no examples with an explicit dynamic solution were given the present paper provides a fully worked out example that fills this gap and that can serve as a confirmation of romer s claim that monotonically increasing growth rates for the capital stock and for consumption can arise in the framework he specified this paper also presents an example that can generate increasing growth rates without imposing some of the restrictions essential to romer s model those restrictions are not appealing on economic grounds and were added to his paper purely for technical reasons any infinite horizon model with increasing returns to scale must impose some restrictions to ensure the existence of both a social optimum and a competitive equilibrium otherwise the discounted sum of utility could go to infinity romer 1986b used a production function of the form f k k akvkw with v y 1 where k is the capital stock at the level of the firm and k is aggregate capital the

alternative government financing and stochastic endogenous growth abstract this paper addresses a stochastic endogenous model in which the stock of securities both money and bonds are required to finance the government budget we study how the expected rate of real growth the expected inflation rate and economic welfare are influenced by changes in the first and second moments of public spending the analyses will enable us to assess the merits and demerits of mixed financing case of money and bonds relative to financing one of taxes on wealth examined in grinols and turnovsky j econom dyn control 17 1993 1 and turnovsky int econom rev 34 1993 953 in addition we construct a model where government relies on a larger ratio of bonds to money to raise the necessary revenue and show how the consequences of mixed financing are affected by the policy decision of government

the wealth effects of the risk based capital requirement in banking the evidence from the capital market abstract the imposition of risk based capital requirements has been advocated by some regulatory authorities as a means of mitigating the incentive problems created by fixed premium deposit insurance however their imposition also constitutes a requirement to maintain an exogenously influenced capital structure which may adversely affect the values of the firms involved this paper examines the wealth effects of the announcement of the basle committee s intention to impose across international boundaries a pre determined minimum level of risk adjusted capital we find that in general the equity values of a sample of large publicly traded banks decrease at the time of the announcement further those banks with capital levels which are deficient relative to the mandated levels suffer the largest relative losses

an examination of the impact of the garn st germain depository institutions act of 1982 on commercial banks and savings and loans this paper evaluates the effects of events leading to the passage of the garn st germain depository institutions act of 1982 the evidence suggests that the call for reform by president reagan s housing commission and the senate passage of the bill produced positive abnormal returns to stockholders of large savings and loans and commercial banks stockholders of small s ls and banks on the other hand generally experienced negative abnormal returns furthermore when hopes of passage of the act faded significant negative positive abnormal returns were experienced by stockholders of large small s ls and banks this study examines the impact of the passage of the garn st germain depository institutions gsgdi act of 1982 on commercial bank and savings and loan stockholder returns the gsgdi act represents one of two major revisions of the financial system over the last twenty years the other being the depository institutions deregulation and monetary control act of 19801 the proposal for such a change reflected the growing inadequacy of the regulatory structure of financial institutions to adapt to rapid changes in technology shifting consumer demands for financial services and extremely volatile interest rates efforts to reform the financial system resulted in passage of the gsgdi act of 1982 which included provisions seeking to improve both the implementation of monetary policy and the degree of equity in the regulation of financial institutions such improvements were intended to reduce the operational and financial risk of financial institutions a central issue in the economics of regulation is whether regulatory actions benefit the economic agents they are intended to benefit a large body of literature exists which examines the economic effects of regulation much of this literature has utilized the concepts and methods of welfare economics to assess the extent

productivity growth and the structure of the business cycle abstract over the recent years opportunity cost oc models of growth have argued that recessions are times when firms engage in productivity improving activities because of intertemporal substitu tion this paper tests whether this approach is correct the technique used to disentangle the trend from the cycle is semi structural vector autoregression the results are mildly supportive of the oc theory there tends to be a negative impact of demand shocks on productivity both in the short run and in the long run and the short run impact is stronger in those countries where fluctuations are more transitory however there is no significant response of r d to demand shocks

capital income taxation and risk taking in a small open economy abstract how do capital income taxes affect household portfolio choice and growth we approach this question within the context of a stochastic model of a small open economy in which taxes on income from domestic capital equity and foreign bonds affect household portfolio choice welfare and the growth rate of the economy the theoretical and numerical analysis demonstrates the important role that risk plays in determining the mean and variability of growth as well as the conditions under which a higher tax rate can be welfare improving to shed more light on the complex theoretical interaction between taxes and risk taking we estimate a reduced form multinomial probit model of household portfolio choice using the method of simulated moments the empirical evidence is in stark contrast to the conventional wisdom we find that higher taxes make it less likely that the household will hold risky assets

growing through cycles the neoclassical growth model focuses on factor accumulation as an engine of growth while the neo schumpetarian growth model stresses innovation this paper argues that these two views of growth may capture different phases of a single growth experience in the model presented below the balanced growth path is unstable and the economy achieves sustainable growth through cycles under an empirically plausible condition perpetually moving back and forth between two phases one phase is characterized by higher output growth higher investment no innovation and a competitive market structure the other phase is characterized by lower output growth lower investment high innovation and a more monopolistic market structure both investment and innovation are essential in sustaining growth indefinitely and yet they move in an asynchronized way only one of them appears to play a dominant role in each phase the economy grows faster along the cycles than along the unstable balanced growth path

the regulation of international lending imf support the debt crisis and bank stockholder wealth abstract in a recent article cornell landsman and shapiro 1986 provide insight in to the impact of selected regulatory responses to the international debt crisis on bank stock prices the current study concentrates on the reaction of bank shareholders to the legislative events that ultimately led to the passage of the international lending supervision act ilsa and to greater u s support of the international monetary fund imf while cornell landsman and shapiro restricted their legislative analysis to when the relevant bills were passed this study also examines when such legislation was introduced in the house or the senate the empirical results indicate that the introduction of such legislation materially influenced bank stockholder expectations in contrast to cornell landsman and shapiro the effect of these events on the risk return complexion of banks is measured furthermore the sensitivity of bank stockholders reactions to the above legislative events is appraised in light of banks latin american loan portfolio risk analysis of the expected impact of greater imf support and the ilsa on bank stockholders supplements the work of cornell landsman and shapiro by providing additional insight into the expected impact of such legislation on bank industry risk unlike cornell landsman and shapiro this study provides evidence that the joint effect of a greater imf quota and the ilsa was a net benefit to stockholders analysis suggests that the perceived benefit of a greater imf quota was apparently diminished by the ilsa however stockholders evidently perceived a general decrease in the risk of the banking industry as a result of the legislative events

taxation risk taking and growth a continuous time stochastic general equilibrium analysis with labor leisure choice abstract this paper investigates the equilibrium relationship between taxation portfolio choice risk taking and capital accumulation specifically it examines how taxes affect risk taking and capital accumulation we extend the existing literature by relaxing two crucial assumptions in modelling risk taking behavior i that the investment opportunity set is fixed and ii that there is no distinction between attitudes towards risk and behavior towards intertemporal substitution we extend the investment opportunity set of individuals through optimally determined human capital and distinguish intertemporal substitution from attitudes towards risk via a recursive utility function in the presence of these extensions the paper successfully derives a closed form solution to the stochastic growth model with stochastic wage income

bank acquisition and stockholders wealth abstract bank mergers are a control mechanism for reallocating resources because regulation has a pervasive influence on bank decision making unlike industrial firms bank mergers are subject to regulatory approval bank shareholder returns are analyzed at the time of federal reserve approval of mergers to assess whether regulation reduces differential information between bank managers and outsiders or reduces managers ability to take advantage of differential information empirical tests indicate there are negative returns to acquiring banks for external mergers but normal returns for internal mergers emergency mergers generate positive returns before and upon announcement more negative results occur in states with branching restrictions and in cases when equity financing is used

r d expenditure in g7 countries and the implications for endogenous fluctuations and growth abstract the literature on endogenous growth cycles predicts countercyclical r d expenditure aggregate r d expenditure in g7 countries from 1973 to 2000 tends to be procyclical implications for future theoretical research are discussed

growing through cycles in an infinitely lived agent economy abstract this paper extends the analysis of k matsuyama econometrica67 1999 335 347 to the case of an infinitely lived representative agent economy the economy grows endogenously through endogenous fluctuations perpetually moving back and forth between two phases in one phase there is no innovation the market structure is competitive and the economy grows solely by capital accumulation in the other phase new goods are introduced and the market structure is monopolistic in the long run both investment and innovation grow at the same rate but the economy alternates between the periods of high investment and the periods of higher innovation journal of economic literature classification numbers e32 o11

market structure and transaction costs implied spreads in the german stock market abstract in this paper the short run behavior of stock prices in the german stock market is investigated and an implied bid ask spread is calculated the german stock market operates for the most part according to auction market principles and bid and ask prices are not continuously posted by dealers yet implied spreads calculated from the serial covariance of transaction prices are positive and exhibit the same characteristics as implied spreads on u s dealer markets

divergence in economic performance transitional dynamics with multiple equilibria abstract special pairs of the utility functions and the production functions are used in this paper to uncover the transitional dynamics in a lucas model of growth the main findings are as follows a continuum of equilibria exists if the external effect of human capital in goods production is sufficiently large the process of lagging behind catching up with and overtaking that we often observe in the world economy can be explained finally some equilibrium paths are shown to have such complicated patterns that the dynamics conjectured by lucas are too simple to be correct journal of economic literature classification numbers o41 c61

optimal timing of technology adoption abstract in a dynamic programming framework this paper investigates the optimal timing of technology adoption by a competitive firm when technology choice is irreversible and the firm faces a stochastic innovation process with uncertainties about both the speed of the arrival and the degree of improvement of new technologies a numerical example illustrates how the optimal timing decision is affected by changes in parameter values reflecting market conditions the firm s initial technological attributes and the characteristics of the stochastic innovation process some of these effects turn out to be in sharp contrast to common intuition contrasting the optimal decision rule derived here with the rule obtained under the net present value shows that the former implies a slower pace of adoption than implied by the latter the optimal decision rule is generalized for the case of multiple technology switches and it is shown that for all the switching decisions except the last one the optimal rule satisfies the net present value criterion

infrastructure alternative government finance and stochastic endogenous growth abstract this paper constructs a stochastic version of an endogenously growing economy with a public good that raises the productivity of private capital we explore how growth and welfare are influenced by changes in the mean and variance of productive public spending under two alternative financing methods mixed money bond financing and wealth tax financing in addition to evaluate the differences between money financing and bond financing we consider mixed money bond financing under which a larger ratio of bonds to money is utilized to finance a given increase in public spending

long run implications of investment specific technological change an attempt is made to disentangle its effects from the more traditional hicksneutral form of technological progress the balanced growth path for the model is characterized and calibrated to u s national income and product account nipa data the quantitative analysis suggests that investment specific technological change accounts for the major part of growth jel e13 030 041 047

endogenous growth cycles current explanations why a growing economy necessarily goes through periods of high and low growth predict countercyclical r d investment as this is very controversial from an empirical perspective a stochastic poisson model of endogenous growth cycles is presented where the determinants of the cyclical behaviour of r d investment are analytically studied providing an explicit expression for the expected length of a cycle shows that high frequency fluctuations can indeed be understood by this approach it is also shown how small technological improvements translate into large aggregate fluctuations

the impact of an unexpected political resignation on exchange rates based on the theory of economic regulation political shocks are examined as unexpected events in the light of the efficient markets hypothesis and a political resignation is taken as an example of such an event the hon j dawkins mp resigned as the federal treasurer of the australian government on friday 17 december 1993 there have been a number of studies on the effect of economic and political events on stock prices this study considers the impact of dawkin s resignation on the foreign exchange rates of the major traded currencies in australia the traditional event study methodology based on the market model and the lesser used multivariate methodology of seemingly unrelated regressions are used for the analysis the sample of currencies is considered both as a portfolio and on an individual basis with efficiency of the currency markets being tested for anticipatory event related and persistence effects the paper concludes by contrasting the findings of the two methodologies the study repo

the impact of the 1980 depository institutions deregulation and monetary control act on market value and risk evidence from the capital markets the depository institutions deregulation and monetary control act of 1980 brought about major changes in the banking industry this study employs capital market data to examine the act s impact on the relative competitive positions of distinct classes of firms within the industry the evidence supports the hypothesis that federal reserve system banks profited from the regulatory change at the expense of nonmember banks and savings and loans copyright 1988 by ohio state university press

the economic determinants of technology shocks in a real business cycle model abstract creative destruction due to new technologies causes both long run growth and short run business fluctuations new technologies push the economy on a higher productivity level but also imply partial obsolescence of old production units obsolescence induces an adjustment period during which growth rates gradually fall at some endogenously determined point research for the next technology starts once the new technology is discovered a technology shock occurs and the next cycle starts this is shown in a continuous time rbc model with risk averse agents where savings can be used for financing deterministic capital accumulation and stochastic r d for new technologies

growth cycles and market crashes abstract market booms are often followed by dramatic falls to explain this requires an asymmetry in the underlying shocks a straightforward model of technological progress generates asymmetries that are also the source of growth cycles assuming a representative consumer we show that the stock market generally rises punctuated by occasional dramatic falls with high risk aversion bad news causes dramatic increases in prices bad news does not correspond to a contraction of existing production possibilities but to a slowdown in its expansion this economy provides a model of endogenous growth cycles in which recoveries and recessions are dictated by the adoption of innovations journal of economic literature classification numbers o40 g12 o41 o30

the profitability of momentum strategies momentum strategies based on continuations in stock prices have attracted a wide following among money managers and investors we evaluated the profitability of price momentum strategies based on past return and earnings momentum strategies based on standardized unexpected earnings and revisions of consensus forecasts the strategies proved to be profitable for intermediate horizons chasing momentum can generate high turnover however hence implementation of momentum strategies requires a focus on managing trading costs comparing the strategies yielded evidence that they reflect distinct phenomena and provided information about the sources of profits the results indicate that the market is slow to incorporate the full impact of information in its valuations

the speed of convergence and alternative government financing abstract in this paper we are concerned with the speed of convergence in the sidrauski monetary optimizing model sidrauski am econ rev 57 1967 534 in which the steady state capital stock is not influenced by a change in public spending the paper studies how different the speed of convergence to the steady state is affected by a change in government spending under the various ways of financing in exploring the transitional adjustment to the public policy shock it will be convenient to focus upon the degree of relative risk averse

alternative government financing and aggregate fluctuations driven by self fulfilling expectations abstract using woodford s finance constrained model woodford m 1986 stationary sunspot equilibria in a finance constrained economy journal of economic theory 40 128 137 with external effects in production as in barinci and cheron 2001 sunspots and business cycle in a finance constrained economy journal of economic theory 97 30 49 this paper investigates the effects of alternative government financing methods on the range of values of increasing returns leading to an indeterminate steady state it will be shown that indeterminacy may easily arise at a wide range of values of increasing returns if constant government expenditure is financed through labor income taxes and with difficulty if constant government expenditure is financed by taxes on capital in addition we explore how the consequences of endogenous income taxes are changed if tax rates on labor and capital income are kept constant and government expenditure is endogenously adjusted to satisfy the budget constraint

animal spirits through creative destruction we show how a schumpeterian process of creative destruction can induce rational herd behavior by entrepreneurs across diverse sectors as if fueled by animal spirits consequently a multisector economy in which productivity improvements are made by independent profit seeking entrepreneurs exhibits regular booms slowdowns and downturns as part of the long run growth process our cyclical equilibrium has higher average growth but lower welfare than the corresponding acyclical one we show how a negative relationship can emerge between volatility and growth across cycling economies and assess the extent to which our model matches several features of actual business cycles

analysis of a two sector model of endogenous growth with capital income taxation this paper addresses a two sector model of endogenous growth in which one sector produces final goods and the other produces new human capital both sectors employ human as well as physical capital under constant returns to scale technologies unlike existing studies of this type of model that have mostly concentrated on steady state analysis or on numerical simulations of calibrated models this paper presents an analytical argument concerning the dynamic behavior of the growth path and the effects of capital income taxation in and out of the steady growth equilibrium it is demonstrated that the dynamic behavior of the economy and some policy effects depend heavily upon the magnitude of factor intensity used in each production sector copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the accumulation of wealth and the cyclical generation of new technologies a search theoretic approach in this paper sustained technological progress results from the feedback between technical change and the accumulation of wealth the production technology is affected by a productivity factor which ensues from research and development the research and development process is described as a sequential search problem in which optimal decisions depend on current levels of wealth and technology the resulting growth path displays invention cycles a discovery of a significant technological improvement at the end of a search phase is followed by periods of growth without search eventually sufficient wealth is accumulated research and development resumes and a new cycle begins copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association
