efficiency in the factoring industry the efficiency and productivity in the italian factoring industry between 1993 and 1997 is investigated using dea the factoring industry is an important part of many financial systems and it has established itself as a major source of finance and credit management for a growing number of companies however as far as the authors are aware no studies have applied frontier methodologies to examine the efficiency and productivity of this industry this paper focuses on the italian market the second largest in the world after the uk the results suggest that there are substantial cost savings to be had in the italian factoring industry the mean cost inefficiency in the italian factoring industry over the period 1993 1997 ranged between 14 and 22 these inefficiencies are mainly generated by allocative rather than technical inefficiencies scale and technical inefficiencies seem to be similar in magnitude and the supposed importance of the latter typically found in the banking efficiency literature are n

nominal income targeting in an open economy optimizing model abstract this paper presents simulation results regarding the performance of nominal income targeting a monetary policy rule that sets interest rates in response to deviations of nominal gdp growth from a target path the macroeconomic model is one in which agents solve dynamic optimization problems with rational expectations but in an environment with slow price adjustments in the present version consumption choices reflect habit formation and the economy is open to international flows of goods and securities when calibrated to quarterly us data the model s results suggest that nominal income targeting performs well in relation to inflation targeting and taylor rules

policy options in a liquidity trap the specter of a liquidity trap originally proposed as a theoretical possibility by john maynard keynes 1936 but long considered to be of doubtful practical relevance has recently created alarm among the world s central banks in japan the overnight rate has been essentially at zero for most of the time since february 1999 making further interest rate cuts impossible yet until well into 2003 growth remained anemic while prices continued to fall suggesting a need for further monetary stimulus since march 2001 the bank of japan has supplemented its zero interest rate policy with a policy of quantitative easing under which additional bank reserves are supplied beyond those needed to keep overnight interest rates at zero yet an increase in base money of more than 50 percent failed to halt the deflation suggesting a liquidity trap more recently other central banks including the fed have come close enough to the zero bound to worry about how they would deal with a similar predicament here we first discuss whether monetary policy should actually become ineffective when the zero bound on interest rates is reached we argue that open market operations even of unconventional types will be ineffective if they do not change expectations about the future conduct of policy in this sense a liquidity trap is possible nonetheless a credible commitment regarding future policy can largely mitigate the distortions created by the zero bound we fully characterize the optimal commitment in a simple example

a model of target changes and the term structure of interest rates abstract we investigate the effects of short term rate targeting by the federal reserve on the term structure of interest rates and make contributions at two levels using a new series of interest rate targets made available by the federal reserve bank of new york we develop a family of models that highlight the implications of discrete changes in interest rate targets for the term structure of interest rates we show that spreads between short term rates and the overnight federal reserve funds rate are mainly driven by expectations of changes in the target not by the transitory dynamics of the overnight rate around the target hence the bias in tests of the expectations hypothesis that we document can be mainly attributed to the erroneous anticipation of future changes in monetary policy our modeling assumptions and newly available data make it possible to extract a series of market expectations of the next target change which are compared with a series of realized target changes

monetary policy inclinations we examine whether central banks should complement their inflation forecasts with interest rate projections introducing a central bank loss function that accounts for deviations from announcements we incorporate the publication of policy inclinations into a dynamic monetary model we show that in the presence of cost push shocks the publication of interest rate forecasts tends to improve welfare

total factor productivity and the convergence hypothesis in the italian regions this article is aimed at testing the catching up hypothesis for the italian regions the use of malmquist productivity indices allows to decompose productivity growth into technological progress and technical efficiency change interpreted respectively as innovation and catching up measurements the analysis leads to a conclusion that regional economies diverge at a decreasing rate

measuring hospital performance a non parametric approach abstract in this paper a technique for assessing the relative performance of firms is introduced and applied to a sample of hospitals in california hospitals are compared on the basis of their relative technical efficiency the reference technology is constructed from observed outputs and inputs including physicians using programming techniques and efficiency is assessed relative to the frontier of the technology using measures similar to those suggested by farrell the technique used here imposes no prespecified functional form allows for multiple outputs and inputs allowing for differences in case mix and yields information on the productive performance of individual hospitals this technique can also be used to determine whether different types of hospitals use different technologies our results although illustrative rather than definitive suggest that ownership affects efficiency as measured here public and nfp hospitals have different best practice frontiers and public hospitals appear to use relatively fewer resources these results could reflect differences in quality of care by ownership

a note on the linsanity of measuring the relative efficiency of national basketball association guards this note examines the productive efficiency of 62 starting guards during the 2011 12 national basketball association nba season this period coincides with the phenomenal and largely unanticipated performance of new york knicks starting point guard jeremy lin and the attendant public and media hype known as linsanity we employ a data envelopment analysis dea approach that includes allowance for an undesirable output here turnovers per game with the desirable outputs of points rebounds assists steals and blocks per game and an input of minutes per game the results indicate that depending upon the specification between 29 and 42 of nba guards are fully efficient including jeremy lin with a mean inefficiency of 3 7 and 19 2 however while jeremy lin is technically efficient he seldom serves as a benchmark for inefficient players at least when compared with established players such as chris paul and dwayne wade this suggests the uniqueness of jeremy lin s productive solution and may ex

assessing nominal income rules for monetary policy with model and data uncertainty nominal income rules for monetary policy have long been debated but two issues are of particular recent interest first there are questions about the performance of such rules over a range of plausible empirical models especially models with and without explicit rational inflation expectations second there are questions about the performance of these rules in real time using the type of data that is actually available contemporaneously to policy makers rather than final revised data this paper determines optimal monetary policy rules in the presence of such model uncertainty and real time data uncertainty and finds only a limited role for nominal output growth

announcements of interest rate forecasts do policymakers stick to them if central banks value the ex post accuracy of their forecasts previously announced interest rate paths might affect the current policy rate we explore whether this forecast adherence has influenced the monetary policies of the reserve bank of new zealand and the norges bank the two central banks with the longest history of publishing interest rate paths we derive and estimate a policy rule for a central bank that is reluctant to deviate from its forecasts the rule can nest a variety of interest rate rules we find that policymakers appear to be constrained by their most recently announced forecasts

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

determinacy and identification with taylor rules the new keynesian taylor rule theory of inflation determination relies on explosive dynamics by raising interest rates in response to inflation the fed induces ever larger inflation unless inflation jumps to one particular value on each date however economics does not rule out explosive inflation so inflation remains indeterminate attempts to fix this problem assume that the government will choose to blow up the economy if alternative equilibria emerge by following policies we usually consider impossible the taylor rule is not identified without unrealistic assumptions thus taylor rule regressions do not show that the fed moved from passive to active policy in 1980

measuring managerial efficiency the case of baseball in economic analysis the role of the entrepreneur is paramount to the production process the entrepreneur is engaged in a darwinian game of efficiently transforming scarce resource inputs into outputs in the modern business organization this role is delegated to managers despite the conceptual importance of the role of management in the production function very little is known about the actual effect on output of variations in managerial skill in part this is due to the lack of proprietory data in part it is due to difficulties in measuring the outputs and inputs of complex production processes in a meaningful way a number of investigators have employed the concept of the frontier production function as developed by forsund and hjalmarsson 1 and timmer 6 and more recently by schmidt and lovell 3 to measure the effect on technical and price efficiency of various property rights structures or institutional constraints to our knowledge estimates of managerial efficiency have not been obtained with firm specific data except for some regulated industries in this study we estimate managerial efficiency by manager and by firm managerial marginal revenue product the rate of change in managerial efficiency over years of experience and relative factor price efficiency we use major league baseball teams over the period 1961 1980 as our data source what is particularly appealing about the choice of major league baseball teams as the industry for analysis is that outputs win percent and inputs player skills are unambiguously measured and the production function is simply specified as shown by scully 5 our results indicate that managerial skill in baseball contributes very substantially to the production process the paper will evolve as follows first the concept of the frontier production function is briefly outlined then estimates of managerial efficiency by manager and by team are provided and discussed a managerial efficiency learning curve is estimated an estimate of managerial marginal revenue product provided and the managerial efficiency

scoring on the stock exchange the effect of football matches on stock market returns an event study we analyse the effect of results of football matches on the stock market performance of football teams we analyse 1274 matches of eight teams in the national and european competition during 2000 2004 we find that the stock market response is significant and positive for victories and negative for defeats the response is significantly stronger in the case of defeat the response is stronger for matches in the european competition than for those in the national competition unexpected results have a stronger impact for european matches than expected ones but this is not the case in the national competition

stop go monetary policy we propose and estimate several discrete choice models of monetary policy decision making that feature time varying inertia the models permit us to account for three stylized facts characterizing monetary policymaking in the united states 1 target interest rates are gradually adjusted in small discrete movements 2 there are some long stretches of time in which rates are repeatedly moved and 3 there are other long stretches in which the policy rate does not change our models are used to account for the fed s failure to adopt promptly an easier policy stance during the recession of 2001 they are also used to explain delay in tightening the policy stance during the 2003 2006 period that featured a bubble in house prices and was followed by a financial crisis in 2008

habit formation in consumption and its implications for monetary policy models this paper explores a monetary policy model with habit formation for consumers in which consumers utility depends in part on current consumption relative to past consumption the empirical tests developed in the paper show that one can reject the hypothesis of no habit formation with tremendous condence largely because the habit formation model captures the gradual hump shaped response of real spending to various shocks the paper then embeds the habit consumption specication in a monetary policy model and nds that the responses of both spending and inflation to monetary policy actions are signicantly improved by this modication jel d12 e52 e43

solution and estimation of re macromodels with optimal policy macro models of monetary policy typically involve forward looking behavior except in rare circumstances we have to apply some numerical method to find the optimal policy and the rational expectations equilibrium this paper summarizes a few useful methods and shows how they can be combined with a kalman filter to estimate the deep model parameters with maximum likelihood simulations of a macro model with staggered price setting interest rate elastic output and optimal monetary policy illustrate the properties of this estimation approach

analysing the technical efficiency of the spanish football league first division with a random frontier model this article analyses technical efficiency of football clubs in the spanish football league division 1 primera liga from the seasons 1995 1996 to 2004 2005 with an unbalanced panel data the random frontier model is used allowing the identification of random variables in the cost frontier it is concluded that the price of capital investment the number of points won and attendance are heterogeneous variables therefore no common public policy aiming to improve efficiency can embrace all of the clubs so that policies by clusters are required

does publication of interest rate paths provide guidance abstract does the central bank practice of publishing interest rate projections irps improve how market participants map new information into future interest rates using high frequency data on forward rate agreements fras we compute market forecast errors differences between expected future interest rates and ex post realizations we assess their change in narrow windows around monetary policy announcements and macroeconomic releases in norway and sweden overall communication of future policy plans does not improve markets response to information irrespective of whether or not irps are in place a decomposition of market reactions into responses to the current monetary policy action target and responses to signals about the future path reveals that only policy actions lead to improvements in market forecasts

the un importance of forward looking behavior in price specifications the seminal work of edmund s phelps 1978 john b taylor 1980 and guillermo a calvo 1983 developed forward looking models of price determination that imparted inertia to the price level these models incorporate expectations of future prices and excess demand by imposing constraints typically lag lead symmetry constraints that force future variables to enter the specification in this paper the author tests the empirical significance of future prices in specifications like those of taylor he finds that expectations of future prices are empirically unimportant in explaining price and inflation behavior however the dynamics of a model that includes a purely backward looking inflation specification differ substantially and not altogether pleasingly from those with a forward looking specification copyright 1997 by ohio state university press

malmquist indices of productivity change in the uk gas industry before and after privatization the uk government s privatization programme was justified in terms of potential efficiency gains this paper concentrates on measures of technical efficiency in the regions of the uk natural gas industry before and after privatization and the associated regulatory changes it uses non parametric frontier analysis and malmquist indices to show that the rate of productivity growth increased significantly after privatization however the differences in technical efficiency amongst regions remain suggesting that failure to break up the industry has sacrificed potential gains from direct competition or indirect competition through yardstick regulation

monetary policy shifts and long term interest rates the pure expectations hypothesis peh serves as the benchmark model for the relationship between yields on bonds of different maturities when coupled with rational expectations however empirical renderings of the model fail miserably i explore the possibility that failure to account for changes in monetary policy regime explains much of the failure of the peh estimating changing monetary regimes in conjunction with the peh significantly improves its performance the predicted spread between the long and short rates is highly correlated with the actual spread the standard deviation of the theoretical spread is nearly identical to that of the actual spread

inflation targeting some extensions previous analyses of the implementation of inflation targeting are extended to monetary policy responses to different shocks consequences of model uncertainty and effects of interest rate smoothing and stabilization model uncertainty output stabilization and interest rate stabilization or smoothing all call for a more gradual adjustment of the conditional inflation forecast toward the inflation target the conditional inflation forecast is the natural intermediate target during inflation targeting the optimal way of reacting to shocks is hence to check how they affect the inflation forecast and then take the appropriate action jel classification e42 e52 e58

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

monetary policy trade offs and the correlation between nominal interest rates and real output the authors present a structural model of the u s economy that combines their price contracting specification with a term structure relationship an aggregate demand curve and a monetary policy reaction function the model matches important features of postwar data well and provides a structural explanation of the correlation between real output and the short term nominal rate of interest the authors perform a battery of monetary policy experiments that show that as viewed through the lens of this model monetary policy has struck a good balance recently among competing monetary policy objectives copyright 1995 by american economic association

monetary policy surprises and interest rates evidence from the fed funds futures market abstract this paper estimates the impact of monetary policy actions on bill note and bond yields using data from the futures market for federal funds to separate changes in the target funds rate into anticipated and unanticipated components interest rates response to anticipated target rate changes is small while their response to unanticipated changes is large and highly significant these responses are generally consistent with the expectations hypothesis of the term structure surprise target rate changes have little effect on expectations of future actions however which helps to explain the lack of empirical support for the expectations hypothesis at the short end of the yield curve

comparing french and us hospital technologies a directional input distance function approach french and us hospital technologies are compared using directional input distance functions the aggregation properties of the directional distance function allow comparison of hospital industry level performance as well as standard firm level performance with regard to productive efficiency in addition the underlying constituents of efficiency in the short run congestion and technical inefficiency and in the long run scale inefficiency are analysed by decomposing the overall measure by virtue of using the directional distance function it is also possible to obtain an estimate of a lower bound on allocative inefficiency it is found that french and us hospitals use quite different technologies long run scale inefficiencies cause most of the french hospitals inefficiency while short run technical inefficiency is the main source of overall productive inefficiency in the us hospitals

the behavior of interest rates implied by the term structure of eurodollar futures this paper considers an equilibrium model of the term structure that is determined by two stochastic factors a short term interest rate and a target level to which the short rate is expected to revert a kalman filter technique that uses a time series cross section of eurodollar futures prices is developed to estimate the parameters of the model the term structures of spot libor and eurodollar futures volatility are compared to that predicted by the model the empirical results indicate that the two factor specification represents a significant improvement over its one factor version copyright 1996 by ohio state university press

term structure evidence on interest rate smoothing and monetary policy inertia abstract numerous studies have used quarterly data to estimate monetary policy rules or reaction functions that appear to exhibit a very slow partial adjustment of the policy interest rate the conventional wisdom asserts that this gradual adjustment reflects a policy inertia or interest rate smoothing behavior by central banks however such quarterly monetary policy inertia would imply a large amount of forecastable variation in interest rates at horizons of more than 3 months which is contradicted by evidence from the term structure of interest rates the illusion of monetary policy inertia evident in the estimated policy rules likely reflects the persistent shocks that central banks face

does the fed act gradually a var analysis abstract the tendency for changes in the federal funds rate to be implemented gradually has been considered evidence of an interest rate smoothing objective for the federal reserve this paper investigates whether gradual funds rate movements can be explained by the dynamic structure of the economy and the uncertainty surrounding that structure without recourse to including an ad hoc interest rate smoothing argument in the fed s objective function in the absence of parameter uncertainty the optimal policy involves more aggressive movements in the funds rate than observed parameter uncertainty however limits the responsiveness of the interest rate as a result the optimal policy under parameter uncertainty can account for a considerable portion of the gradualism observed

an analysis of the risk in discretely rebalanced option hedges and delta based techniques the stochastic properties of discretely rebalanced option hedges have been studied extensively beginning with black and scholes 1973 in each analysis hedges were delta neutral after rebalancing we argue that the distributional properties of discretely rebalanced hedges are such that delta based hedging is not the variance minimizing strategy this paper obtains analytical expressions for the variance minimizing option hedge ratios we also evaluate the hedge variance to assess the magnitude of the variance reduction over delta based hedges for representative parameter values we show that systematic departures from delta based hedges can yield significant reductions in hedge variance even for one day rebalancing intervals

more on the speed of adjustment in inventory models when empirical stock adjustment models of manufacturers inventories of finished goods are estimated there appear to be two local minima in the sum of squared residuals functions at one local minimum the estimated adjustment speed is typically quite high at the other it is typically quite low furthermore finding two sets of estimates that fit the data almost equally well does not appear to be a quirk of this particular application rather it stems from a fundamental identification problem that afflicts partial adjustment models of all kinds in the specific context of manufacturers inventories of finished goods the estimation procedure employed by maccini and rossana seems to pick out the solution with rapid adjustment and high serial correlation in the disturbances whereas the solution with slow adjustment and little serial correlation is more often the global minimum this abstract was borrowed from another version of this item
