decentralized and concentrated investments in china and the performance of taiwanese listed electronic companies abstractever since china surpassed taiwan to become the largest exporter of electronic products dependence between the two sides has deepened which prompts taiwanese companies to go public in china this study conducted the data envelopment analysis dea and regression analysis to analyse the impacts of the depth and breadth of investments in china on the performance of taiwanese listed electronic companies the empirical results show that the breath of the investments in china has a positive correlation with the performance of taiwanese companies while the depth of investments in china has a negative and significant effect on the performances due to the companies lack of know how which leads to a high learning cost in summary companies should strategize their decentralized and concentrated investments in china

the use of parametric and non parametric frontier methods to measure the productive efficiency in the industrial sector a comparative study abstract parametric frontier models and non parametric methods have monopolised the recent literature on productive efficiency measurement empirical applications have usually dealt with either one or the other group of techniques this paper applies a range of both types of approaches to an industrial organisation setup the joint use can improve the accuracy of both although some methodological difficulties can arise the robustness of different methods in ranking productive units allows us to make a comparative analysis of them empirical results concern productive and market demand structure returns to scale and productive inefficiency sources the techniques are illustrated using data from the us electric power industry

the adjustment cost model of the firm duality and productive efficiency we present the theoretical foundation for an adjustment cost technology that supports the intertemporal production decision making behavior using the directional distance function dynamic input efficiency measures are developed that can separate out the impact of variable and dynamic factors inefficiency levels an approach to implement this theory in a nonparametric fashion is developed and applied to an unbalanced panel of dutch glasshouse firms the application finds overuse of all variable inputs and overcapitalization of installations the overall dynamic efficiency gain of 16 remains possible with allocative inefficiencies indicating underinvestment in structures and installations a comparison of static and dynamic efficiency measures finds that the static overall cost inefficiency is overestimated with technical inefficiency being overstated and allocative inefficiency being understated

the out of sample success of term structure models as exchange rate predictors a step beyond abstract a large literature suggests that standard exchange rate models cannot outperform a random walk forecast and that the forward rate is not an optimal predictor of the spot rate however there is evidence that the term structure of forward premia contains valuable information for forecasting future spot exchange rates and that exchange rate dynamics display nonlinearities this paper proposes a term structure forecasting model of exchange rates based on a regime switching vector equilibrium correction model which is novel in this context our model significantly outperforms both a random walk and to a lesser extent a linear term structure vector equilibrium correction model for four major dollar rates across a range of horizons

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

giving money to get money how ceo stock options and ceo equity enhance ipo valuations recent research has suggested that stock options and equity ownership have different motivational implications for executive risk taking we examined investors reactions to the differing incentive

ceo characteristics and firm r d spending over the past fifteen years a number of studies have examined the determinants of firm r d spending these studies however almost invariably focus on the role of firm or external ownership characteristics in predicting r d spending while overlooking the attributes of the top managers involved in allocating corporate resources in this study we change that focus by empirically examining how r d spending as compared to industry competitors varies at firms based on the characteristics of their ceos using a sample of publicly traded firms we find that ceo characteristics explain a significant proportion of the sample variance in firm r d spending even when corporate strategy ownership structure and other firm level attributes are controlled in terms of individual ceo characteristics we find that r d spending is greater at firms where ceos are younger have greater wealth invested in firm stock and signifacant career experience in marketing and or engineering r d in contrast to existing theory we find that the amount of a ceo s formal education had no significant association with r d spending once a ceo has attained a college degree however significant r d spending increases are found at firms where ceos have advanced science related degrees from subgroup analyses we further find that ceo effects on relative r d spending increase with longer ceo tenure implying that ceos over time may mold r d spending to suit their own preferences from these results we make implications for both research on determinants of r d spending and managerial practice

management ownership and market valuation an empirical analysis we investigate the relationship between management ownership and market valuation of the firm as measured by tobin s q in a 1980 cross section of 371 fortune 500 firms we find evidence of a significant nonmonotonic relationship tobin s q first increases then declines and finally rises slightly as ownership by the board of directors rises for older firms there is evidence that q is lower when the firm is run by a member of the founding family than when it is run by an officer unrelated to the founder

level slope curvature of the sovereign yield curve and fiscal behaviour abstract we study fiscal behaviour and the sovereign yield curve in the us and germany we obtain the latent factors level slope and curvature with the kalman filter and use them in a var with macro fiscal and financial stress variables in the us fiscal shocks generate an immediate response of the short end of the yield curve associated with monetary policy lasting 6 8 quarters followed by a response of the whole yield curve lasting 3 years with an implied elasticity of long term yields of 80 for the government debt shock and 48 for the budget balance shock in germany fiscal shocks have entailed no significant reactions of the yield curve shape and no response of the monetary policy interest rate notably after 1999 only in the case of debt shocks there is a short lived decrease in the medium end of the yield curve in the following 2nd and 3rd quarters

the impact of foreign board membership on firm value abstract this study examines the effect of foreign anglo american board membership on corporate performance measured in terms of firm value tobin s q using a sample of firms with headquarters in norway or sweden the study indicates a significantly higher value for firms that have outsider anglo american board member s after a variety of firm specific and corporate governance related factors have been controlled for we argue that this superior performance reflects the fact that these companies have successfully broken away from a partly segmented domestic capital market by importing an anglo american corporate governance system such an import signals a willingness on the part of the firm to expose itself to improved corporate governance and enhances its reputation in the financial market

exchange rate puzzles and distorted beliefs abstract we propose a new explanation for the foreign exchange forward premium and delayed overshooting puzzles we show that both puzzles arise from a systematic distortion in investors beliefs about the interest rate process accordingly the forward premium is always a biased predictor of future depreciation the bias can be so severe as to lead to negative coefficients in the fama regression delayed overshooting may or may not occur depending upon the persistence of interest rate innovations and the degree of misperception we document empirically the extent of this distortion using survey data for g 7 countries against the u s and find that it is strong enough to account for these irregularities

corporate governance and innovation a survey abstract the traditional economics of innovation inspired by schumpeter and more recent advances on his work seem unable to explain why firms with similar external conditions may show greatly different performance in innovation contrastingly the literature on corporate governance provides some useful insights for understanding corporate innovation activity to the extent that such literature examines the economic effects of different modes of coordination between firm members the process through which individuals integrate their human and physical resources within the firm is central to the dynamics of corporate innovation this paper provides the first survey of the literature on this issue we start by discussing how various theoretical approaches to the analysis of the firm deal with technological innovation we then describe three main channels corporate ownership corporate finance and labour through which a system of corporate governance shapes a firm s innovation activity finally we examine the relationship between country level institutional settings national patterns of corporate governance and the aggregate innovation activity of corporations we conclude by suggesting that future research should focus more deeply on the interrelation between the various dimensions of corporate governance and on their joint effect on firm innovation

nonparametric efficiency analysis under uncertainty using data envelopment analysis abstract production and cost frontiers of a firm in an industry are directly affected by the uncertainty of market demand and the uncertainty of input availability the nonparametric approach of data envelopment analysis dea is generalized here in both static and dynamic directions by incorporating these uncertainties the paper addresses an extension of the convex hull method of dea for determining a production frontier in the presence of demand and supply uncertainty of outputs and inputs respectively this is illustrated by an empirical application to the computer industry

equity valuation under bull and bear market regimes in south east asia firms a switching regression approach a switching regression approach is used to analyse the market equity value of firms in the three south east asia countries with a comparison to japan two regimes are used to optimally sort the firms in a given country based on a switching function using profit rate net income to book equity as its variable the regimes are identified as a bear security market or a bull security market depending on the value of the profit rate two financial ratios are used in the regime regressions it was found that the optimum scaled switch point separating the bulls from the bears for the countries was a positive profit rate ranging between 6 and 24 the notion that a zero or negative profit rate identifies a bear market is not supported in general the results across countries and for the long term debt ratio were quite consistent the post asian financial crisis of 1997 had a depressing effect on firm market equity values regardless of the market type and the country the bulls and the bears are not cousins whe

dynamic data envelopment analysis modeling intertemporal behavior of a firm in the presence of productive inefficiencies abstract this study extends data envelopment analysis dea to a dynamic framework our dynamic dea not only provides a measure of dynamic productive efficiency but can also be used as a nonparametric alternative to the econometric modeling of the intertemporal behavior of a firm

measuring dynamic efficiency under risk aversion abstract problems of measuring the efficiency of decision making units are discussed here in an intertemporal framework where both current and capital inputs are used to produce outputs it is assumed that the units are risk averse and they attempt to adjust their short run input decisions so as to attain the intertemporally optimal expansion paths by using an adjustment cost approach the influence of risk aversion and output fluctuations on the dynamic production frontier are analyzed by a set of optimal control models

the use of foreign currency derivatives corporate governance and firm value around the world abstract this paper examines the impact of currency derivatives on firm value using a broad sample of firms from thirty nine countries with significant exchange rate exposure derivatives can be used for managers self interest for hedging or for speculative purposes we hypothesize that investors can appeal to a firm s internal firm level and external country level corporate governance to draw inferences on a firm s motive behind the use of derivatives since well governed firms are more likely to use derivatives to hedge rather than to speculate or pursue managers self interest consistent with this explanation we find strong evidence that the use of currency derivatives for firms that have strong internal firm level or external country level governance is associated with a significant value premium

corporate capital expenditure decisions and the market value of the firm abstract this paper is an event time study of the common stock prices of a sample of 658 corporations around the dates on which they publicly announced their future capital expenditure plans for industrial firms announcements of increases decreases in planned capital expenditures are associated with significant positive negative excess stock returns for public utility firm neither increases nor decreases in planned capital expenditures are associated with significant excess stock returns we interpret the evidence as being consistent with the hypothesis that managers seek to maximize the market value of the firm in making their corporate capital expenditure decisions

determinants of sovereign yield spreads in the eurozone a bayesian approach abstract we analyze the determinants of sovereign yields spreads of emu member states applying bayesian model averaging bma to annual panel data from 1999 to 2009 bma is well suited in cases of small samples and high model uncertainty this seems to be the case in modeling sovereign yield spreads in the eurozone since the literature reports heterogeneous results with respect to significant explanatory variables we are testing a number of variables reported to be significant in the literature and find that the most likely country specific drivers of yield spreads are fiscal variables such as budget balance and government debt as well as external sector variables such as terms of trade trade balance and openness global financing conditions indicated by the us interest rate and market sentiments indicated by corporate bond spreads are likely to influence sovereign yield spreads

linked cone dea profit ratios and technical efficiency with application to illinois coal mines data envelopment analysis dea profit ratios and technical efficiency measures require separate treatment as proved in newly developed theory of thompson and thrall this point is illustrated here by analysis of an example problem it shows that dea technical efficiency does not necessarily imply a dea maximum profit ratio and vice versa a dea maximum profit ratio does not necessarily imply dea technical efficiency the essence of the mathematical framework underlying this argument is provided application of the concepts to illinois coal mining data previously reported lends support to the need for separate treatment of dea technical efficiency and dea profit ratios

corporate governance environmental regulations and technological change abstract this paper investigates the relationship between environmental regulations and innovation by focusing on the automobile industry in a cross country setting we provide empirical evidence that the presence of agency problems mitigates the negative effects of environmental regulations on overall r d activity which leads to full compensation when the degree of agency problems is sufficiently high guiding our empirical analysis we provide a general model consistent with the structure of existing ownership data specifically we model ownership structure as a combination of two extreme corporate governance types on the one extreme there are profit maximizers and on the other extreme there are managers who are only concerned with their private benefits the model leads to a simple country level ownership indicator and shows that if an economy is dominated by firms with higher agency problems then pollution tax might even increase overall r d while reducing pollution according to our estimations such an outcome is possible only for out of sample values of the ownership indicator where the degree of agency problems is extremely high

a partial adjustment approach to evaluating and measuring the business value of information technology abstract in this paper we develop a partial adjustment approach based on the theory of partial adjustment to assess the value of information technology we also propose a performance measure derived from the approach the constrained structural or implicit and unconstrained non structural or explicit models derived from the approach are fitted into a set of panel data at the country level covering the period from 1993 to 2006 for a sample of 12 countries including the g7 nations and are estimated by the seemingly unrelated regression estimation the results produced by the models are robust with respect to the choice of the production function representing the true desired or maximum output and challenge the widely held belief that the productivity paradox has disappeared and the view that the productivity paradox exists in developing economies only the proposed approach compares favorably with the time varying stochastic production frontier approach since it is easier and simpler to apply but unlike the non parametric data envelopment analysis approach it is parametric

average q marginal q and the relation between ownership and performance abstract using average performance measures as the literature does to investigate the relation between ownership structure and performance suffers from severe drawbacks we propose a marginal tobin s q and argue for its superiority

estimating most productive scale size using data envelopment analysis abstract the relation between the most productive scale size mpss for paparticular input and output mixes and returns to scale for multiple inputs multiple outputs situations is explicitly developed this relation is then employed to extend the applications of data envelopment analysis dea introduced by charnes cooper and rhodes ccr to the estimation of most productive scale sizes for convex production possibility sets it is then shown that in addition to productive inefficiencies at the actual scale size the ccr efficiency measure also reflects any inefficiencies due to divergence from the most productive scale size two illustrations of the practical applications of these results to the estimation of most productive scale sizes and returns to scale for hospitals and stem electric generation plants are also provided emphasize the advantage of this method in examining specific segments of the efficient production surface

the agency problems embedded in firm s equity investment we find that agency problems are embedded in firm s excess and abnormal equity investments that are mainly dictated by controlling shareholder s motives and ethical choices manifested in ownership and board structure the excess equity investment is gauged with respect to industry average the abnormal equity investment is specifically referred to the number of nominal investment companies that are fully controlled by the controlling owners while subject to little governance our empirical evidences of 345 taiwanese non financial listed firms show that firm s excess and abnormal equity investments are negatively correlated with controlling shareholder s cash flow rights while are positively correlated with the control cash flow deviation and board affiliation the results are supportive of the positive incentive hypothesis and the negative entrenchment hypothesis put forth by la porta et al 2002 journal of finance57 1147 1171 and claessen et al 2002 journal of finance57 2741 2742 the negative relation between equity investment and firm s value further supports the agency postulation that corporate excess and abnormal equity investments represent a leeway for controlling shareholder to exploit wealth of minority shareholders this study potentially contributes to the literature of business ethics by portraying an empirically testable linkage from controlling owner s ethical choices to his actions and therefore firm s value

ownership and firm innovation in a transition economy evidence from china we examine innovation performance of firms in a transition economy from an ownership perspective we focus specifically on the relationship between ownership structures and firm innovation performance drawing on data from 548 chinese firms we find volume of patent registration to be most strongly influenced by foreign ownership in the firm along with firm affiliation within a business group the influence of state and institutional ownership on innovation performance is positive but lagged contrary to expectations insider ownership leads to lower innovation performance and concentrated ownership has no significant impact our study has two principal contributions firstly we utilize a comprehensive treatment of ownership characteristics overcoming weakness in previous studies that have used a more narrow focus on ownership type secondly we contribute to understanding of how firms in transition economies build indigenous capabilities for innovation by drawing attention to the interplay of foreign and domestic control of agents innovation

does ownership structure of emerging market firms affect their outward fdi the case of the indian automotive and pharmaceutical sectors this paper examines the impact of ownership structures of emerging market firms which are shaped by local institutions on the decision of these firms to undertake outward fdi our results suggest that family firms and firms with concentrated ownerships both ubiquitous in emerging markets are less likely to invest overseas and that strategic equity holding by foreign investors facilitates outward fdi we conclude that organisational forms such as family firms which are optimal outcomes of institutions prevailing in emerging markets may be suboptimal in a changing business environment in which outward fdi is necessary for access to resources and markets

macro factors and the term structure of interest rates this paper presents an essentially affine model of the term structure of interest rates making use of macroeconomic factors and their long run expectations the model extends the approach pioneered by kozicki and tinsley 2001 by modeling consistently long run inflation expectations simultaneously with the term structure application to the u s economy shows the importance of long run inflation expectations in the modeling of long term bond yields the paper also provides a macroeconomic interpretation for the latent factors found in standard finance models of the yield curve the level factor represents the long run inflation expectation of agents the slope factor captures business cycle conditions and the curvature factor expresses a clear independent monetary policy factor

exchange rate predictability the main goal of this article is to provide an answer to the question does anything forecast exchange rates and if so which variables it is well known that exchange rate fluctuations are very difficult to predict using economic models and that a random walk forecasts exchange rates better than any economic model the meese and rogoff puzzle however the recent literature has identified a series of fundamentals methodologies that claim to have resolved the puzzle this article provides a critical review of the recent literature on exchange rate forecasting and illustrates the new methodologies and fundamentals that have been recently proposed in an up to date thorough empirical analysis overall our analysis of the literature and the data suggests that the answer to the question are exchange rates predictable is it depends on the choice of predictor forecast horizon sample period model and forecast evaluation method predictability is most apparent when one or more of the following hold the predictors are taylor rule or net foreign assets the model is linear and a small number of parameters are estimated the toughest benchmark is the random walk without drift

efficiency and its determinants in pharmaceutical industries ownership r d and scale economy the purpose of this article is to measure the efficiency of pharmaceutical firms and identify their determinants using korean and american samples from 1992 to 2004 we document some stylized facts in the patterns and sources of efficiency change in korean and american pharmaceutical firms the evidence shows that ownership structure can substantially influence the efficiency of pharmaceutical firms especially institutional ownership rate affects corporate efficiencies negatively corroborating the myopic institutional investor hypothesis the hypothesis is supported by both korean and american samples however we find evidence that foreign ownership in korea promotes efficiency of pharmaceutical firms it is shown that r d intensity is positively related to contemporaneous largest ownership rate and prior foreign ownership rate in korean pharmaceutical firms in contrast little evidence is found on the relationship between ownership structure and r d intensity in the american pharmaceutical industry

measurement of multiperiod aggregative efficiency abstract this article proposes a new method for measuring an aggregative efficiency of multiple period production systems every organization or firm generates a time series of data that represent its performances in the resource utilization and output production over multiple periods and often desires an aggregated measure of efficiency for several periods of interest data envelopment analysis dea has become an accepted and well known approach to evaluating efficiency performance in a wide range of cases however most of the dea studies have dealt primarily with ways to gauge the efficiency of production in only a single period so this efficiency reflects the insufficient or partial performance of multiple period productions the new method is developed through extensions of the concept of debreu farrell technical efficiency and is applied to evaluating the efficiency of cable tv service units with 3 year data

dominant institutional owners and firm value abstract this research analyzes the impact of control by dominant institutional owners banking institutions and investment funds on firm value the analysis considers the level of voting rights in the hands of the dominant institutional owner and other large shareholders the results reveal a different effect on value depending on whether the dominant institutional investor is a banking institution or an investment fund moreover the results show that the presence of other large shareholders affects firm value when a dominant institutional owner controls the firm

structural models and endogeneity in corporate finance the link between managerial ownership and corporate performance this paper presents a parsimonious structural model that isolates primary economic determinants of the level and dispersion of managerial ownership firm scale and performance and the empirical associations among them in particular variation across firms and through time of estimated productivity parameters for physical assets and managerial input and corresponding variation in optimal compensation contract and firm size combine to deliver the well known hump shaped relation between tobin s q and managerial ownership to assess the effectiveness of standard econometric approaches to the endogeneity problem we apply those remedies to panel data generated from the model the unfortunate conclusion is that at least in the ownership performance context proxy variables fixed effects and instrumental variables do not generally provide reliable solutions to simultaneity bias

a macro finance model of the term structure monetary policy and the economy this paper develops and estimates a macro finance model that combines a canonical affine no arbitrage finance specification of the term structure with standard macroeconomic aggregate relationships for output and inflation from this new empirical formulation we obtain several interesting results 1 the latent term structure factors from finance no arbitrage models appear to have important macroeconomic and monetary policy underpinnings 2 there is no evidence of monetary policy inertia or a slow partial adjustment of the policy interest rate by the federal reserve and 3 both forward looking and backward looking elements play important roles in macroeconomic dynamics

term structure surprises the predictive content of curvature level and slope summary this paper analyzes the predictive content of the term structure components level slope and curvature within a dynamic factor model of macroeconomic and interest rate data surprise changes of the three components are identified using sign restrictions and their macroeconomic underpinnings are studied via impulse response analysis the curvature factor is found to carry predictive information both about the future evolution of the yield curve and the macroeconomy in particular unexpected increases of the curvature factor precede a flattening of the yield curve and announce a significant decline of output more than 1 year ahead copyright 2010 john wiley sons ltd

revisiting the expectations hypothesis of the term structure of interest rates the expectations hypothesis of the term structure has been decisively rejected in a large empirical literature that spans several decades in this paper using a newly constructed dataset of synthetic zero coupon bond yields we show that evidence against the expectations hypothesis is substantially weaker in data generated after the widespread publicity of its failure these results are consistent with the idea that asset pricing anomalies tend to disappear once they are widely recognized

sovereign bond yield spreads a time varying coefficient approach abstract we study the determinants of sovereign bond yield spreads across 10 emu countries between q1 1999 and q1 2010 we apply a semiparametric time varying coefficient model to identify to what extent an observed change in the yield spread is due to a shift in macroeconomic fundamentals or due to altering risk pricing we find that at the beginning of emu the government debt level and the general investors risk aversion had a significant impact on interest differentials in the subsequent years however financial markets paid less attention to the fiscal position of a country and the safe haven status of germany diminished in importance by the end of 2006 two years before the fall of lehman brothers financial markets began to grant germany safe haven status again one year later when financial turmoil began the market reaction to fiscal loosening increased considerably the altering in risk pricing over time period confirms the need of time varying coefficient models in this context

profits persistence and ownership evidence from the italian banking sector the hypothesis that ownership structure affects persistence of profits in the italian banking industry is tested the time invariant components of roa and roe are regressed against ownership concentration and the fraction of shares held by the major shareholders the results show that abnormal profits increase if ownership is concentrated in foundations and banks and decrease if market forces are allowed to operate

temporal technical and profit efficiency measurement definitions duality and aggregation results abstract the shortage function an important tool in production theory measures potential increases in outputs and decreases in inputs for a given direction g at a given date to develop a temporal version of technical efficiency measurement we introduce the concept of a temporal shortage function this temporal efficiency measure is easily computed using linear programming we also establish a duality result stating that the temporal profit function and the temporal shortage function are dual to one another this result has two consequences first one can derive a shadow price path via the shadow prices of the temporal shortage function second transposing the classic farrell inefficiency decomposition temporal profit efficiency is decomposed into temporal technical and temporal allocative efficiency components finally in line with the recent literature on aggregation over firms this contribution treats the possibilities and limits of the aggregation of efficiency measures over time

common factors in international bond returns in this paper we estimate and interpret the factors that jointly determine bond returns of different maturities in the us germany and japan we analyze both currency hedged and unhedged bond returns for currency hedged bond returns we find that five factors explain 96 5 of the variation of bond returns these factors can be associated with changes in the level and steepness of the term structures in some of these countries in particular it turns out that changes in the level of the term structures are correlated across countries while changes in the steepness of the term structures are country specific the five factor model also provides a good fit of the expected returns of bond returns in all countries we find similar results for bond returns that are not hedged for currency risk finally we show how the model can be used to calculate the value at risk for international bond portfolios and to price cross currency interest rate derivatives and compare the results with simpler models

corporate performance and managerial remuneration an empirical analysis abstract economic theories of efficient compensation predict a positive relationship between executive pay and corporate performance and yet efforts to document this relationship have been largely unsuccessful in this paper we argue that previous cross sectional studies have omitted important variables which seriously bias their results using data that focus on individual executives over time we find that executive compensation is strongly positively related to corporate performance as measured by shareholder return and growth in firm sales the results are robust to the stock market performance measure utilized

a dynamic efficiency model using data envelopment analysis abstract changes in productivity due to technological progress or regress are incorporated in models of data envelopment analysis dea in two ways either through a network technology or in terms of a capacity variable or capital input embodying technical progress the second way is analyzed here in terms of time varying capital inputs due to the changes in input prices over time this provides an optimal control theoretic view of the time path of capital inputs which minimizes a discounted sum of total input costs for each dmu the cost of risk aversion and the adjustment cost of input price fluctuations may then be minimized in an extended dea model framework these extensions of the dea model are analyzed here and illustrated by an empirical application to international airlines data

working capital and fixed investment new evidence on financing constraints this article presents new tests for finance constraints on investment by emphasizing the often neglected role of working capital as both a use and a source of funds the coefficient of endogenous working capital investment is negative in a fixed investment regression as expected if working capital competes with fixed investment for a limited pool of finance this finding addresses a criticism of previous research on finance constraints that cash flows may simply proxy shifts in investment demand in addition previous studies may have underestimated the impact of finance constraints on growth and investment because firms smooth fixed investment in the short run with working capital

economics of efficiency measurement by the dea approach three aspects of efficiency measurement by data envelopment analysis are discussed here analytically these aspects comprise output specific input allocations by each firm flexibility in the production process and the role of learning by doing in efficiency improvement

an alternative conditioning scheme to explain efficiency differentials in banking abstract we investigate whether specialization ownership type or size bias bank efficiency the approach we apply focusing on the entire distributions of efficiency scores sheds light on the firms precise relative positions when controlling for these firms characteristics results suggest that conclusions related to this topic should consider these techniques given efficiency scores generated by nonparametric techniques are clearly dependent on each other in the statistical sense

corporate structure liquidity and investment evidence from japanese industrial groups this paper presents evidence suggesting that information and incentive problems in the capital market affect investment we come to this conclusion by examining two sets of japanese firms the first set has close financial ties to large japanese banks that serve as their primary source of external finance and are likely to be well informed about the firm the second set of firms has weaker links to a main bank and presumably faces greater problems raising capital investment is more sensitive to liquidity for the second set of firms than for the first set the analysis also highlights the role of financial intermediaries in the investment process

a joint measurement of efficiency and effectiveness for non storable commodities integrated data envelopment analysis approaches efficiency and effectiveness for non storable commodities represent two distinct dimensions and a joint measurement of both is necessary to fully capture the overall performance this paper proposes two novel integrated data envelopment analysis idea approaches the integrated charnes cooper and rhodes iccr and integrated banker charnes and cooper ibcc models to jointly analyze the overall performance of non storable commodities under constant and variable returns to scale technologies the core logic of the proposed models is simultaneously determining the virtual multipliers associated with inputs outputs and consumption by additive specifications for technical efficiency and service effectiveness terms with equal weights we show that both iccr and ibcc models possess the essential properties of rationality uniqueness and benchmarking power a case analysis also demonstrates that the proposed novel idea approaches have higher benchmarking power than the conventional separate dea approaches more generalized specifications of idea models with unequal weights are also elaborated

a reconsideration of the uncovered interest parity relationship abstract this paper argues that the uncovered interest parity uip relationship is distinct from and more important than the unbiasedness of forward exchange rates as predictors of future spot rates the standard finding that the slope estimate b is roughly 3 in regressions of s t on t 1 s t 1 implies rejection of unbiasedness but not necessarily uip the hypothesis that monetary authorities manage interest rates so as to smooth their movements while also resisting changes in exchange rates is attractive conceptually and is capable of explaining not only the b 3 finding but also several other notable features of the data

ownership structure investment and the corporate value an empirical analysis this paper examines the relation among ownership structure investment and corporate value focusing on whether ownership structure affects investment ordinary least squares regression results suggest that ownership structure affects investment and therefore corporate value however simultaneous regression results indicate that the endogeneity of ownership may affect these inferences suggesting that investment affects corporate value which in turn affects ownership structure the evidence shows that corporate value affects ownership structure but not vice versa these findings raise questions regarding the assumption that ownership structure is exogenously determined and bring into question the results in studies that treat ownership structure as exogenous

a multivariate latent factor decomposition of international bond yield spreads a factor analysis of long term bond spreads is performed by decomposing international interest rate spreads into national and global factors the factors are latent and are assumed to have garch type specifications as well as exhibiting serial dependence an indirect estimator is used to compute estimates of the unknown parameters the sampling performance of this estimator is investigated and compared with an alternative direct estimator based on the kalman predictor the factor model is applied to weekly data on long bond spreads between five countries australia japan germany canada and the uk and the usa over the period 1991 to 1999 the resulting factor decomposition is used to examine the international investor s optimal portfolio decision in a mean variance framework copyright 2000 john wiley sons ltd

yield factor volatility models the term structure of interest rates is often summarized using a handful of yield factors that capture shifts in the shape of the yield curve in this paper we develop a comprehensive model for volatility dynamics in the level slope and curvature of the yield curve that simultaneously includes level and garch effects along with regime shifts we show that the level of the short rate is useful in modeling the volatility of the three yield factors and that there are significant garch effects present even after including a level effect further we find that allowing for regime shifts in the factor volatilities dramatically improves the model s fit and strengthens the level effect we also show that a regime switching model with level and garch effects provides the best out of sample forecasting performance of yield volatility we argue that the auxiliary models often used to estimate term structure models with simulation based estimation techniques should be consistent with the main features of the yield curve that are identified by our model

the contribution of economic fundamentals to movements in exchange rates starting from the asset pricing approach of engel and west we examine the degree to which fundamentals can explain exchange rate fluctuations we show that it is not possible to obtain sharp inferences about the relative contribution of fundamentals using only data on observed monetary fundamentals money minus output differentials across countries and exchange rates we use additional data on interest rate and price differentials along with the implications of the monetary model of exchange rates to decompose exchange rate fluctuations in general we find that money demand shifts along with observed monetary fundamentals are an important contributor to exchange rate fluctuations

rational inefficiency adjustment costs and sequential technologies abstract in this paper we propose a novel approach to estimate the rational inefficiency of decision making units in the presence of adjustment costs using sequential definitions of the production technology we show how cost inefficiency can be decomposed into rational and residual inefficiency as well as inefficiency caused by technical change furthermore we estimate lower bounds for the unobserved adjustment costs based on unexploited cost reductions due to rational inefficiency these adjustment costs are used to evaluate the feasibility of exploiting cost reductions caused by residual inefficiency we demonstrate the empirical applicability of our model by estimating and decomposing the cost inefficiency of u s coal fired power plants using panel data which cover the period between 1994 and 2009

economic efficiency and frontier techniques abstract most of the literature related to the measurement of economic efficiency has based its analysis either on parametric or on non parametric frontier methods the choice of estimation method has been an issue of debate with some researchers preferring the parametric and others the non parametric approach the aim of this paper is to provide a critical and detailed review of both core frontier methods in our opinion no approach is strictly preferable to any other moreover a careful consideration of their main advantages and disadvantages of the data set utilized and of the intrinsic characteristics of the framework under analysis will help us in the correct implementation of these techniques recent developments in frontier techniques and economic efficiency measurement such as bayesian techniques bootstrapping duality theory and the analysis of sampling asymptotic properties are also considered in this paper

accounting for a shift in term structure behavior with no arbitrage and macro finance models this paper examines a shift in the dynamics of the term structure of interest rates in the u s during the mid 1980s we document this shift using standard interest rate regressions and using dynamic a ne no arbitrage models estimated for the pre and post shift subsamples the term structure shift largely appears to be the result of changes in the pricing of risk associated with a level factor using a macro nance model we suggest a link between this shift in term structure behavior and changes in the dynamics and risk pricing of the federal reserve s in ation target as perceived by investors

factors of the term structure of sovereign yield spreads abstract we investigate the term structure of sovereign yield spreads for five advanced economies against the us and provide novel insights on the key drivers of the term structure we show that the spread term structure dynamics are driven by three latent factors which can be labeled as spread level slope and curvature similar to common interpretations found in the yield curve literature we further show that these estimated spread factors have predictive power for exchange rate movements and excess returns above the predictability of an uncovered interest rate parity approach as the yield curve contains information about expected future economic conditions we conjecture that these yield spread factors reflect expected macroeconomic differentials which in turn drive exchange rates using the information content of yield spread curves may thus be a promising approach to improve the forecasting accuracy of exchange rate models

dynamic data envelopment analysis a relational analysis abstract this paper proposes a dynamic data envelopment analysis dea model to measure the system and period efficiencies at the same time for multi period systems where quasi fixed inputs or intermediate products are the source of inter temporal dependence between consecutive periods a mathematical relationship is derived in which the complement of the system efficiency is a linear combination of those of the period efficiencies the proposed model is also more discriminative than the existing ones in identifying the systems with better performance taiwanese forests where the forest stock plays the role of quasi fixed input are used to illustrate this approach the results show that the method for calculating the system efficiency in the literature produces over estimated scores when the dynamic nature is ignored this makes it necessary to conduct a dynamic analysis whenever data is available
