factor use and productivity change in the alcoholic beverage industries 1 introductiondemands for wine beer and spirits are in view of their substitutable nature often studied in conjunction with one another heien and pompelli 1989 nelson 1999 yet the alcoholic beverage industries are connected by similarities in their production processes and inputs as well as by the demand substitutability of their products lea and piggott 1995 these industries are therefore usefully examined together when questions about technical change and productivity growth arise little recent attention has been given to the nature of technical adjustments in the beer sector and no such work seems ever to have been published on wine and spirits 1brewing and distilling and to a smaller extent winemaking have become increasingly mechanized during the past half century as they have in most other manufacturing sectors packaging rates are higher shelf lives longer and storage and transportation technology improved tremblay 1987 elzinga 1990 pp 216 219 iserentant 1995 piggott and conner 1995 gisser 1999 the fixed costs associated with these innovations have broadly speaking served as an incentive to build fewer and larger plants industry concentration in the beer sector rose dramatically from the mid 1930s through the mid 1980s plant numbers then expanded as microbreweries catered to the new demand for product variety and idiosyncrasy although four firm concentration continued to rise through the mid 1990s in the spirits sector domiciled largely in the south distillery numbers continue to decline spurred by declining aggregate demand as well as scale economies no such broad consolidation is taking place in the wine industry where several california and new york firms long have occupied a substantial market share instead wineries numbers have grown rapidly and uninterruptedly since 1970 proliferating in regions long thought inhospitable to wine grape production growing consumer interest in wine variety and microclimates a trend similar to that for microbrews has abetted this diversification goodhue et al 2000 prices in the alcoholic beverage industries have in real terms fallen substantially in the past 40 years net prices to brewers have dropped 37 to wineries 16 and to distillers 31 at the same time real wage rates generally have risen and except for brief instability during the 1970s so have capital rental prices real material prices in all three sectors rose from the 1950s through the 1960s fell through the 1970s then recovered by the mid 1990s to their early 1970s levels relative factor prices in the beer industry broadly representative of those in the other two sectors are shown in figure 1 wage rates rose relative to both capital and material prices until 1980 thereafter wages fell relative to capital but continued to rise relative to material prices u s bureau of the census various years expenditure shares illustrated in figure 2 suggest that the beer industry is the most capital intensive of the three sectors by the mid 1990s capital expenditures represented one third of beer production costs compared to only one fifth of wine and distilling costs on the other hand raw materials constituted little more than half of beer expenses but nearly 70 of wine and distilling costs labor accounted for only 10 12 of expenditures in any of these industries figure 2 seems to suggest that at least since the mid 1970s or early 1980s capital has substituted for labor and materials in all three sectors yet as figure 1 reveals much of these share changes are accounted for by the rising relative price of capital the substantial narrowing of output input price margins in the alcoholic beverage sector suggests that the sector has become more cost efficient through either technical change scale economies improved utilization rates or other means technical changes themselves can alter potential scale economies and productive capacities and hence prospects for future variations in industry structure

the impact of the 2008 financial crisis on dynamic productivity growth of the spanish food manufacturing industry an impulse response analysis the emergence of a financial crisis is an event that can impact the fortunes of nearly all economic agents the focus here is on the 2008 financial crisis and how firms productivity growth was impacted by this crisis in the years that followed this article focuses on dynamic productivity growth and its components using a firm level data set of spanish meat processing dairy processing and oils and fats firms the impulse response analysis shows that the impact of the crisis on dynamic productivity growth is negative and persistent in the oils and fats industry initially positive but then negative in the meat processing industry and positive in the dairy processing industry the observed magnitudes of change in indicator are between 2 and 5 for oils and fats industries and of 1 in both dairy and meat industries our analysis further confirms that firms size is an important factor in explaining how crisis impacts dynamic productivity growth and its components while we find only slight evidence regarding the firms experience in the market

econometric developments in agricultural and resource economics the first 100 years this article reviews the major contributions of agricultural and resource economists in the area of econometrics over the past 100 years early on a number of agricultural economists were in on the ground floor in terms of developing new econometric methods over time as the economics profession became more empirically oriented agricultural and resource economists increasingly assumed the role of early adopters of new econometric methods even so agricultural and resource economists continue to make useful modifications to econometric techniques in order to adapt the methods to the unique nature of the problems and applications that we study

post hoc ergo propter once more an evaluation of does monetary policy matter in the spirit of james tobin christina and david romer s paper does monetary policy matter advocates the so called narrative approach to causal inference we demonstrate that this method will not sustain causal inference first it is impossible to distinguish monetary shocks from oil shocks as causes of recessions second a world in which the fed only announces intentions to act cannot be distinguished from one in which it in fact acts third the techniques of dynamic simulation used in the romers study are inappropriate and quantitatively misleading and finally their approach provides no basis for establishing causal asymmetry

size and productivity in the u s milling and baking industries from the late 1950s through mid 1990s productivity growth in u s grain milling and feed manufacturing has been consistently strong and positive in grain milling approximately 15 of the growth is due to size economies technical change has been capital using increasingly material saving and in recent years decreasingly labor saving or increasingly labor using the quality of capital has risen relative to that of labor and materials in all but the baking industry capital intensification and incentives for plant size growth remain unabated copyright 2000 oxford university press

a financial portfolio approach to inventory behaviour japan and the uk abstract the paper analyses the determinants of the inventory to assets ratio in panel data sets of japanese and uk firms in the period 1960 1985 the analytical framework sets inventory decisions in the context of decisions by the firm about other assets and liabilities in contrast to traditional models of inventories investment in inventories in japan is found to be particularly related to sector specific inflation rates and expected sales negatively to expected profits and not much affected by interest rates by contrast uk inventories are generally positively related to profit rates and respond to short term interest rates once other variables are taken into account the coefficient on a time trend is positive for japan negative for britain which casts some doubt on the widely held view of japanese innovation in inventory holding

structural change capital investment and productivity in the food processing industry investment in new technology affects structural change and economic performance through its effect on capital and input composition this is particularly important for capital intensive industries such as food processing which lack short run flexibility due to adjustment costs this study considers the impacts of capital quasi fixity on capital and noncapital input decisions made in the u s food and kindred products industry from 1965 to 1991 a cost based production theory model is used to evaluate investment motivations for three capital components productivity growth accompanying changing input patterns is then discussed focusing on capital and farm input demand

how does the stock market respond to changes in bank lending standards i investigate the industry level responses of u s stock returns to unanticipated changes in bank lending standards exploiting cross industry variation in the levels of dependence on external finance i document that on average cumulative stock returns fall significantly by 1 36 percentage points two years after an unexpected one standard deviation tightening in lending standards moreover moving from an industry at the 10th percentile of financial dependence to one at the 90th percentile adds between 1 24 and 2 19 additional percentage points to this effect

should we be worried about the green paradox announcement effects of the acid rain program this paper presents the first empirical test of the green paradox hypothesis according to which well intended but imperfectly implemented environmental policies may lead to detrimental outcomes due to supply side responses we use the introduction of the acid rain program in the u s as a case study the theory predicts that owners of coal deposits expecting future sales to decline would supply more of their resource between the announcement of the acid rain program and its implementation moreover the incentive to increase supply would be stronger for owners of high sulfur coal this would all else equal induce an increase in sulfur dioxide emissions using data on prices heat input and sulfur content of coal delivered to u s power plants we find strong evidence of a price decrease and of an increase in the sulfur premium some indication that the amount of coal used might have increased and no evidence of fuel switching towards higher sulfur coal overall our evidence suggests that while the mechanism indicated by the theory might be at work market conditions and concurrent regulation largely prevented a green paradox from arising these results have implications for the design of climate policies

the green paradox and budgetary institutions abstract we examine oil production strategies in response to the rise of alternative energy in context of saudi arabia and the united states in a unified simultaneous equation model sem over the period 1976 2015 we investigate the extent to which budget balance behaviour explains the nature of oil production strategies we find that green regulations have a positive impact on u s oil production while an inverse relationship holds for saudi arabia we argue that the nature of budgetary institutions prevents saudi arabia from following a profit maximising behaviour saudi arabia is incentivised to ensure political cohesion through adopting a procyclical fiscal policy rather regulators seem incentivised to channel surplus towards individuals to gain popularity in the united states a thriving shale oil industry is a plausible rationale for u s production strategies also known as a weak green paradox this is problematic for climate change initiatives to reduce global emissions climate experts may wish to pay more attention to the supply side of oil markets when designing decarbonisation plans the results challenge conventional wisdom of the green paradox neglecting the role of incentive structure between different types of oil producers

potential pitfalls for the purchasing power parity puzzle sampling and specification biases in mean reversion tests of the law of one price the ppp puzzle is based on empirical evidence that international price differences for individual goods loop or baskets of goods ppp appear highly persistent or even nonstationary the present consensus is these price differences have a half life that is of the order of five years at best and infinity at worst this seems unreasonable in a world where transportation and transaction costs appear so low as to encourage arbitrage and the convergence of price gaps over much shorter horizons typically days or weeks however current empirics rely on a particular choice of methodology involving i relatively low frequency monthly quarterly or annual data and ii a linear model specification in fact these methodological choices are not innocent and they can be shown to bias analysis towards findings of slow convergence and a random walk intuitively if we suspect that the actual adjustment horizon is of the order of days then monthly and annual data cannot be expected to reveal it if we suspect arbitrage costs are high enough to produce a substantial band of inaction then a linear model will fail to support convergence if the process spends considerable time random walking in that band thus when testing for ppp or loop model specification and data sampling should not proceed without consideration of the actual institutional context and logistical framework of markets

a contribution to event study methodology with an application to the dutch stock market abstract this paper proposes an extended market model for event studies based on daily stock returns for actual data the assumptions of the simple market model are violated the return distribution is not normal and neither the variance of the error term nor the risk parameter beta are constant our model incorporates the generalized autoregressive conditional heteroskedasticity garch model with t distributed errors and a time dependent beta we test for anomalies by adding dummy variables in the regression equation our model is fairly general and could be used in a wide variety of event study situations we illustrate the model by an analysis of the weekend and the option expiration effect we use return data from the dutch stock market the weekend effect on stock returns is significant but no expiration effect could be detected

announcing climate policy can a green paradox arise without scarcity unintended consequences of a pre announced climate policy are studied within a framework that allows for competition between polluting and clean energy sources we show that early announcement of a carbon tax gives rise to a green paradox in that it increases emissions in the interim period between announcement and actual implementation irrespective of the scarcity of fossil fuels the paradoxical outcome is driven by consumption saving tradeoffs facing households who seek to smooth consumption over time and holds both when the announced implementation date is taken as a credible threat and when households are skeptical about the political will or capability of the government to implement the policy as announced

is addiction rational theory and evidence this paper makes two contributions to the modeling of addiction first we provide new and convincing evidence that smokers are forward looking in their smoking decisions using state excise tax increases that have been legislatively enacted but are not yet effective and monthly data on consumption second we recognize the strong evidence that preferences with respect to smoking are time inconsistent with individuals both not recognizing the true dife culty of quitting and searching for self control devices to help them quit we develop a new model of addictive behavior that takes as its starting point the standard rational addiction model but incorporates time inconsistent preferences this model also exhibits forward looking behavior but it has strikingly different normative implications in this case optimal government policy should depend not only on the externalities that smokers impose on others but also on the internalities imposed by smokers on themselves we estimate that the optimal tax per pack of cigarettes should be at least one dollar higher under our formulation than in the rational addiction case

taking stock a critical assessment of recent research on inventories empirical and theoretical aspects of inventory behavior became hot topics in the 1950s and early 1960s no one seemed to notice the tension that was developing between the emerging macroeconomic and microeconomic views of inventories macroeconomists routinely thought of inventories as a destabilizing factor yet the prevailing micro theory viewed inventories as a stabilizing factor it was a fascinating question that was barely explored instead somewhat inexplicably interest in inventories dried up as if inventories were of minor economic significance and little intrinsic interest by the early 1980s then economists once again knew something they had known in the 1950s that inventory investment is of first order importance in business cycles but they were also beginning to realize that the standard production smoothing buffer stock model of inventories was in deep trouble this paper focuses on developments since that realization

aggregation without separability tests of the united states and mexican agricultural production data the generalized composite commodity theorem gcct and testing procedure is extended to test for consistent aggregation of the united states and mexican agricultural production data in each category for which earlier tests rejected homothetic separability nonrejected gcct and separability hypotheses provide empirical support for aggregating all the united states agricultural outputs into as few as two categories crops and livestock mexican agricultural outputs also can be aggregated into as few as two categories support for aggregating all outputs into a single category is ambiguous in both countries and is only provided by the gcct

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

identifying the macroeconomic effect of loan supply shocks the inability to clearly distinguish the effects of shocks to loan supply from those to loan demand has made it difficult to quantify the economic importance of the credit channel in the transmission mechanism of monetary policy this study provides an innovative approach to identifying loan supply shocks three different results confirm that loan supply shocks have been successfully isolated from shifts in loan demand our measure is particularly important for explaining inventory movements the component of gdp most dependent on bank lending the effect is present even during periods with strong loan demand and the effect remains even when the unpredictable part of the loan supply shock is isolated this identification enables us to show that loan supply shocks have had economically important effects on the u s economy

convenience yield without the convenience a spatial temporal interpretation of storage under backwardation a mathematical programming model of the wheat marketing system of western australia manifests a typical pattern of regionwide stocks held at a negative intertemporal spread measured at the port no stocks are held at a monetary loss in terms of local prices any apparent loss is an illusion from spatial aggregation of stocks and attribution of incentives at one locality to storers at all locations moreover as the premium for immediate delivery at the port rises stocks increase at relatively inaccessible inconvenient locations where prices are low allowing more to be shipped from locations more convenient to the port

the production and inventory behavior of the american automobile industry understanding inventory movements is central to an understanding of business cycles this paper presents an empirical study of the behavior of inventories in the automobile industry it finds that inventory behavior is well explained by the assumption of intertemporal optimization with rational expectations the underlying cost structure appears to have substantial costs of changing production as well as substantial costs of being away from target inventory thelatter being a function of current sales given this cost structure whether inventory behavior is stabilizing or destabilizing depends on the characteristics of the demand process in the automobile industry inventory behavior is destabilizing the variance of production is larger than the variance of sales

ordering the extraction of polluting nonrenewable resources energy markets are often characterized by the use of multiple nonrenewable resources such as coal and natural gas with different pollution characteristics the same resource may have different qualities as when high and low sulfur coal is used to generate electricity multiple resources are used in providing transportation services such as cars running on gasoline or plug in hybrids that may be fueled by electricity produced from coal when these nonrenewable resources contribute differentially to pollution what is the opti mal sequence of extraction over time harold hotelling 1931 developed the classical theory of extraction of a nonrenewable resource orris c herfindahl 1967 extended the hotelling model by considering many resources with different unit costs of extraction and proposed the least cost first principle extraction must be ordered by cost with the cheapest resource used first others have examined whether herfindahl s model remains valid in a variety of situations in a general equilibrium setting see murray kemp and ngo v long 1980 tracy r lewis 1982 in the presence of setup costs g rard gaudet moreaux and stephen w salant 2001 under het erogeneous demands chakravorty and darrell l krulce 1994 and when the extraction rate is constrained jean pierre amigues et al 1998 stephen p holland 2003 in these studies following hotelling and herfindahl resources were differentiated by cost alone in this paper we abstract from cost considerations and focus on how the sequence of extraction may be affected when resources are differentiated only by their pollution character istics we consider two resources one more polluting than the other without loss of generality consider coal to be the dirty resource and natural gas the clean one both may be used to generate electricity environmental regulation is imposed through a cap on the stock of pollution this may be a stylized approximation of an international agreement such as the kyoto protocol which aims to stabilize the concentration of greenhouse gases in the atmosphere 1 with heterogeneity in pollution the results are nonintuitive and do not depend on the emis sion rates of the resources when the economy is already at its allowable stock of pollution the clean natural gas is used first and use of the dirty coal is postponed to the future this is what one would expect armed with insights from the herfindahl model however when the economy starts from below the ceiling and accumulates pollution coal may be used first and use of the clean natural gas is postponed the optimal strategy is to benefit from natural dilution by build ing the stock of pollution as quickly as possible this is done by burning coal rather than natural

dynamic measures of scope and scale economies an application to german agriculture static concepts of multiproduct economies of scale and scope are extended into a dynamic setting within the cost of adjustment framework important properties of the dynamic measures are developed and the foundations of a dynamic theory of the firm generalizing static neoclassical theory are presented dynamic measures of scope and scale as well as shadow costs are estimated empirically for multiple output multiple input german dairy farms operating under a production quota causes of scope economies are explored and a conceptual model to predict the evolution of the production structure of german farms is formulated

joint production quasi fixed factors of production and investment in finished goods inventories inventory investment has long been an important area of inquiry for empirical work in macroeconomics this is due in large measure to the fact that inventory investment is a major source of fluctuations in aggregate output empirical work on inventories however has been dominated by the use of simple univariate flexible accelerators 1 the major objective of this paper is to propose and test a multivariate flexible accelerator model for inventory investment the model is tested with data on finished goods inventories from the manufacturing sector of the u s economy there are two reasons for undertaking such a task first at a theoretical level a univariate flexible accelerator model asserts that investment in say finished goods inventories is proportional to the gap between the desired and actual stocks of finished goods such a model presumes that decisions by firms on finished goods inventories are made independently of decisions on other stocks but theory suggests that when firms make simultaneous decisions on a variety of stocks which includes not only finished goods but also goods in process inventories the size of the work force etc decisions on finished goods will interact with decisions on

inventories as factors of production and economic fluctuations this paper presents a theory of inventory investment by stage of processing and uses it to examine the role of inventory investment in economic fluctuations the model in which inventories are treated as factors of production is estimated for four durable goods industries three conclusions emerge from the estimation first the estimates generally satisfy the theoretical restrictions second the elasticity of inventory demand with respect to output is high indicating an important accelerator effect finally the estimates suggest that shifts in the demand for inventories are an important source of economic fluctuations copyright 1989 by american economic association

productivity growth and environmental regulation in mexican and u s food manufacturing many argued during the nafta debate that trade liberalization would favor mexican over u s food processors especially because of lax environmental laws south of the border we find through an examination of profit functions that productivity growth in mexico has outstripped that in the united states suggesting free trade indeed will benefit mexican suppliers u s pollution regulations have had no impact on the profitability or productivity of u s food manufacturing in contrast mexico s swiftly rising environmental standards have enhanced food processors productivity growth corroborating the porter hypothesis pollution law therefore has favored mexican over u s food processing but for reasons few had anticipated

consumer credit liquidity and the transmission mechanism of monetary policy i introduction despite calls for its obsolescence the lending channel of the monetary transmission mechanism continues to generate interest among monetary economists recently den haan sumner and yamashiro 2007 find the loan supply effect is evident for consumer lending and real estate loans in data up to 2004 the loan supply effect or lending channel arises in the transmission mechanism if tight monetary policy forces banks to contract the supply of loans independent of a direct interest rate effect i e the liquidity effect and such a contraction has real effects for bank dependent borrowers although some such as perez 1998 and ashcraft 2006 have emphasized the lending channel s lack of relevance for the monetary transmission mechanism den haan sumner and yamashiro s 2007 results support a number of recent papers that offer detailed and disaggregated reasons why the channel is alive and well for certain lenders and borrowers for recent examples see nilsen 2004 and peek rosengren and tootell 2003 den haan sumner and yamashiro s 2007 findings suggest that the role of the consumer in the lending channel may be deserving of more attention 1 this paper asks whether consumer lending is or has become a significant component of the lending channel even if it was not thought crucial in lending channel studies published in the 1990s specifically i take a closer look at the statistical and possible economic significance of the consumer loan supply effect with disaggregated monthly consumer credit data from both commercial bank and nonbank sources and for the nonrevolving and revolving components of consumer credit from each source with this array of data i test the assumptions of the channel by considering whether households are forced to use more expensive nonbank credit as bank credit declines or that a household might switch into more costly revolving credit as installment loans decline to examine the consumer lending channel i estimate impulse response functions for the disaggregated consumer loan components mentioned above with the monthly data spanning 1968 2006 the sources of which are discussed later this strategy follows the examples of numerous lending channel studies that analyze the responses of disaggregated data to a monetary policy shock to discern evidence of the loan supply effect den haan sumner and yamashiro 2007 e g compare the behavior of commercial and industrial loans with real estate and consumer loans i follow the methods of previous studies in order to compare as closely as possible the results of this paper with the rich body of lending channel literature for robustness this paper estimates the impulse response functions from both a typical vector autoregression var model and using jorda s 2005 linear projection technique the latter method provides impulse response functions less prone to misspecification than in a var along with conditional standard errors to aid in the statistical inference of the responses see also jorda 2009 and further discussion in section iii finally for additional robustness i employ den haan sumner and yamashiro s 2007 identification strategy for isolating the loan supply effect in preview of the results ultimately the consumer credit data analyzed in this paper suggest that both the statistical and by extension the economic significance of the consumer loan supply effect is weak in the least the effect has weakened over time although monthly consumer credit data from commercial banks from 1968 through 2006 substantiate previous research on consumer lending matching the decline documented by gertler and gilchrist 1993 and den haan sumner and yamashiro 2007 after 1984 the responses of both nonrevolving and revolving consumer bank credit are not consistent with the lending channel instead both series increase similar to the result found by den haan sumner and yamashiro 2007 for commercial lending in fact total nonrevolving and revolving consumer credit increase for 2 yr after the monetary shock

banks funding stress lending supply and consumption expenditure we employ a unique identification strategy linking survey data on household consumption expenditure to bank level data to estimate the effects of bank funding stress on consumer credit and consumption expenditures we show that households whose banks were more exposed to funding shocks report lower levels of nonmortgage liabilities this however only translates into lower levels of consumption for low income households hence adverse credit supply shocks are associated with significant heterogeneous effects

quantifying tax effects under policy foresight abstract studies of tax effects make the conventional information assumption that changes in period t taxes become known at t legislative lags however imply that news arrives before tax changes take place under policy foreknowledge the conventional information structure is therefore misspecified simulations of a standard neoclassical growth model suggest that foresight of only one quarter can distort substantially the estimates of tax effects obtained under the no foresight assumption also it is crucial to model capital and labor taxes separately anticipated changes in these two tax policies have opposite effects on consumption investment labor and output before policy realization

rational expectations and the smoothing properties of inventories of finished goods abstract this paper formulates and estimates a dynamic rational expectations equilibrium model of inventories of finished goods and employment of labor the view that the primary role of inventories of finished goods is to act as a buffer stock in the face of fluctuating demand is examined both the model and estimation results indicate that this is the case because of differences in the costs involved for firms in changing their inventory stocks and labor force in addition to providing some new evidence on the behavior of inventories of finished goods and employment the paper illustrates a technology for maximum likelihood estimation of structural parameters under the hypothesis of rational expectations

climate policy and the optimal extraction of high and low carbon fossil fuels we study how restricting co2 emissions affcts resource prices and depletion over time we use a hotelling style model with two nonrenewable fossil fuels that differ in their carbon content e g coal and natural gas and that are imperfect substitutes in final good production we study both an unexpected constraint and an anticipated constraint both shocks induce intertemporal substitution of resource use when emissions are unexpectedly restricted it is cost effective to use high carbon resources relatively more less intensively on impact if this resource is relatively scarce abundant if the emission constraint is anticipated it is cost effective to use relatively more less of the low carbon input before the constraint becomes binding in order to conserve relatively more less of the high carbon input for the period when climate policy is active in case the high carbon resource is relatively scarce abundant

testing the rationality of price forecasts new evidence from panel data this paper tests the rationality of individual price forecasts in a panel of professional forecasters here unlike in most previous studies rationality is not rejected the results here differ because 1 using individual forecasts avoids aggregation bias 2 comparison of forecasts to initial data avoids bias due to data revision 3 the professional forecasters have economic incentives to state their expectations accurately and 4 a new covariance matrix estimator consistent when forecast errors are correlated across individuals is used copyright 1990 by american economic association

international spillovers from euro area and us credit and demand shocks a focus on emerging europe abstract in this paper we examine the international effects of contractions in loan supply loan demand and aggregate demand in the euro area and the usa all three shocks have been at the forefront in spreading stress during the period of the global financial crisis and in particular so to countries that are strongly integrated with the euro area we find that these shocks decrease international output and total credit to a varying degree loan demand and aggregate demand shocks in the euro area trigger significant negative spillovers on output in most other regions evidence for global negative output effects of euro area loan supply shocks is fraught with considerable estimation uncertainty when these three types of shocks emanate from the usa we find significant negative spillovers on output also for loan supply shocks in general international effects on total credit are an order of magnitude larger than those on output with again more evidence that is significant for us than euro area shocks last and taking a regional stance our results indicate that economies from emerging europe are most vulnerable to all shocks considered through their strong economic integration with the euro area these economies are likewise exposed to euro area and us shocks and spillover effects are often larger than the domestic response in the country of shock origin

tracing the effects of agricultural commodity prices and food costs we estimate a system of product and input demand equations for food processing industries to trace the links among farm commodity prices food processing costs and food prices disembodied technical change which likely reflects increasing consumer demand for convenience and product variety has sharply reduced agricultural materials demand relative to most other food processing inputs this implies weakening impacts of farm price shocks on food prices but improving quality and falling relative prices for agricultural inputs in combination with increasing factor substitution has counteracted these forces to encourage greater usage of agricultural inputs in food processing and limit these trends food prices today often appear less responsive to farm price shocks than in the past a development sometimes attributed to failures in market institutions however powerful long run technological and social changes leading to adaptations in production processes and food consumption patterns have also altered the demand for primary agricultural materials by changing the structure of food processing industries the social shifts surrounding the expanded role of women in the labor force represent one striking example of such changes the fraction of married women in the labor force less than one third in 1960 rose sharply through the next three decades before stabilizing at around 61 in the 1990s such demographic shifts increased the demand for food products requiring less home preparation time which in combination with enhanced technology has led to more in plant processing of agricultural materials and likely a growing share of nonagricultural inputs in

dynamic factor demands and the effects of energy price shocks a dynamic model is used to understand how sharp changes in energy prices affect investment behavior employment and energy use the authors discuss the theory behind their model selection model specifications estimation methods and data list parameter estimates and elasticities for the selected model and describe the simulations they conclude that 1 the data strongly reject the hypothesis of constant returns to scale within their specification of aggregate production 2 the data indicate adjustment costs on labor are small and 3 their results help reconcile some of the conflicting estimates of energy demand elasticities appearing in recent literature 23 references 3 figures 3 tables

the real effects of financial sector interventions during crises we assess the importance of supply side credit market frictions by studying the impact of bank recapitalization on firm growth in 50 countries during the recent crisis our identification strategy exploits the crisis as a shock to credit supply and combines an exogenous measure of firms dependence on external financing with policy interventions aimed at restoring bank capital we find that the growth of financially dependent firms is disproportionately positively affected by bank recapitalization this effect is quantitatively important and robust to controlling for other policies these results provide new evidence of the influence of credit market frictions on economic activity

loan supply shocks during the financial crisis evidence for the euro area this paper employs a panel vector autoregressive model for the member countries of the euro area to explore the role of banks during the slump of the real economy that followed the financial crisis in particular we seek to quantify the macroeconomic effects of adverse loan supply shocks which are identified using sign restrictions we find that loan supply shocks significantly contributed to the evolution of the loan volume and real gdp growth in all member countries during the financial crisis however concerning both the timing and the magnitude of the shocks our results also indicate that the euro area was characterized by a considerable degree of cross country heterogeneity

dynamic factor demands under rational expectations we model the industrial demands for structures equipment and blue and white collar labor in a manner consistent with rational expectations and stochastic dynamic optimization in the presence of adjustment costs but allowing generality of functional form we represent the technology by a translog input requirement function that specifies the amount of blue collar labor needed to produce an output level given quantities of three quasi fixed factors nonproduction workers equipment and structures a complete description of the production structure is obtained by simultaneously estimating the input requirement function and three stochastic euler equations we find adjustment costs are small in total but large on the margin and differ considerably across factors

tax reform and adjustment costs the impact on investment and market value this paper provides an effective tax rate measure that is valid in the presence of adjustment costs and anticipated tax changes and a measure of the impact of tax changes on market value that may be decomposed into the effects on discounted pure profits and normal returns to capital changes in the value of capital may in turn be decomposed further into changes in the marginal value of new capital and changes in the relative value of new and existing capital these new measures are used to evaluate tax changes similar to those introduced by the recent u s tax reform copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

is bank supervision central to central banking whether central banks should play an active role in bank supervision and regulation is being debated both in the united states and abroad while the bank of england has recently been stripped of its supervisory responsibilities and several proposals in the united states have advocated removing bank supervision from the federal reserve system other countries are considering enhancing central bank involvement in this area many of the arguments for and against these proposals hinge on the effect this change would have on the ability of the central bank to conduct monetary policy we find that confidential supervisory information on bank ratings significantly improves

an economic analysis of technology in the meat products industry the meat products industry underwent significant structural change during the last two decades the relocation and expansion of commercial cattle feeding stimulated development of new single species slaughtering facilities to replace older multi species plants an essentially new processing industry arose specializing in breaking and packaging carcasses this forward integration has significantly changed distribution methods of slaughtering and fabricating firms increased emphasis on coordination of inputs led to interest in backward integration from packing into cattle feeding the steer and heifer slaughtering sector which was decentralized and competitive in the 1950s has turned toward centralization and concentration although the largest firm accounted for only 13 of total u s steer and heifer slaughter in 1977 it had more than doubled its share since 1970 in 1978 this firm slaughtered more than twice as many steers and heifers as its nearest competitor in addi

financial structure production and productivity evidence from the u s food manufacturing industry this study integrates production and financing to examine the impacts of financial structure change on the production profitability and productivity growth in the u s food manufacturing industry empirical results show that during the period covered by this study agency cost associated with increased debt use by this industry negatively affected its output growth input demand profitability and overall productivity growth dividend payment positively contributed to the production and performance of this industry via signaling benefit however the negative effects of increased debt use by this industry far outweighed the positive contribution of dividend payment the u s food industry achieved a 0 9 average annual productivity growth which came primarily from technological progress and capital adjustment the rapid increase in debt use by this industry was responsible for slowing down the pace of productivity growth via its negative contribution to the total factor productivity growth capital expansion was the principal driver of output growth and profitability in this industry

the relation between forward prices and futures prices abstract this paper consolidates the results of some recent work on the relation between forward prices and futures prices it develops a number of propositions characterizing the two prices these propositions contain several testable implications about the difference between forward and futures prices many of the propositions show that equilibrium forward and futures prices are equal to the values of particular assets even though they are not in themselves asset prices the paper then illustrates these results in the context of two valuation models and discusses the effects of taxes and other institutional factors

the welfare cost of factor taxation in a perfect foresight model this paper examines the marginal efficiency cost of various factor taxes in a dynamic general equilibrium model the au thor solves for the excess burden of anticipated and unanticipated t emporary and permanent tax policies using a range of estimates for taste and technology parameters he finds excess burdens larger than those indicated by previous studies that use static models these exc ess burdens are sensitive to parameter values and timing however th e rankings of alternative tax policies turn out to be insensitive to structural parameter values copyright 1987 by university of chicago press

competitiveness and technical efficiency determinants in the groundnut oil sector of india india imports about half of its domestic consumption needs of edible oils groundnuts are a major source of edible oils in india one of the central problems of groundnut production and processing is huge inefficiencies due to an uncertain production environment owing to rainfed cultivation the low resource base of smallholder farmers and processors and the low adoption rates of improved technology this paper addresses critical issues that impair the groundnut sector s international competitiveness and efficiency the paper uses primary data collected from indian farmers and processors of groundnuts to measure efficiency and it suggests policies for reducing yield gaps and increasing efficiency specific policies suggested from the study are a the harnessing of improved varieties with attributes like drought tolerance high oil content high productivity for large scale seed multiplication and distribution by public and private agencies b viable village seed banks and seed networks through cycles of post rainy season seed multiplication to meet the seed requirements in the rainy season and vice versa c adoption of low cost technologies to increase profitability and reduce risk d oilseed clusters to facilitate scale and scope economies in processing units and e capital subsidies to accelerate technological upgrading to shed inefficiency in the processing sector the expected gains in efficiency in the production and processing of oilseeds are expected to result in producer and consumer gains which would justify the proposed incentives for seeds and for technological upgrading in the processing sector

policy shocks and market based regulations evidence from the renewable fuel standard the renewable fuel standard mandates large increases in u s biofuel consumption and is implemented using tradable compliance credits known as rins in early 2013 rin prices soared causing the regulator to propose reducing future mandates we estimate empirically the effect of three policy shocks that reduced the expected mandates in 2013 we find that the largest of these shocks decreased the value of the fuel industry s 2013 compliance obligation by 7 billion we then study the effects of the shocks on commodity markets and the market value of publicly traded biofuel firms results show that the burden of the mandate reductions fell primarily on advanced biofuel firms and commodity markets of the marginal compliance biofuel we argue that the policy shocks reduced the incentive to invest in the technologies required to meet the future objectives of the rfs and discuss alternative policy designs to address the problems that arose in 2013

the stylized facts about the behavior of manufacturers inventories and backorders over the business cycle 1959 1980 recent theoretical work has highlighted the role of inventories in propagating business cycles this paper attempts to provide an empirical foundation for current and future research on the role inventories play in business cycles the evidence presented here indicates that inventories and backorders are major variables in predicting output fluctuations further the evidence is that disaggregating inventories by stage of fabrication is important in predicting output in concert with previous findings our results suggest that disaggregated inventories ought to be a component of models of the business cycle

can the production smoothing model of inventory behavior be saved the production smoothing model of inventory behavior has a long and venerable history and theoretical foundations that seem very strong yet certain overwhelming facts seem not only to defy explanation within the production smoothing framework but actually to argue that the basic idea of production smoothing is all wrong most prominent among these is the fact that the variance of detrended production exceeds the variance of detrended sales this paper first documents the stylized facts then it derives the production smoothing model rigorously and explains how the model can be amended to make it consistent with the facts finally it reviews the theoretical and empirical evidence and tries to draw some tentative conclusions

event studies in economics and finance the event study is an important research tool in economics and finance the goal of an event study is to measure the effects of an economic event on the value of firms event study methods exploit the fact that given rationality in the marketplace the effects of an event will be reflected immediately in security prices thus the impact can be measured by examining security prices surrounding the event in this paper event study methods are described including some of the potential complications an example is included to illustrate the approach

capital regulation and the macroeconomy empirical evidence and macroprudential policy abstract we present new evidence on the macroeconomic effects of changes in microprudential bank capital requirements using confidential regulatory data from the basel i and ii regimes in the united kingdom our central result is that an increase in capital requirements lowered lending to firms and households reduced aggregate expenditure and raised credit spreads a financial accelerator effect is found to have amplified the macroeconomic responses to shifts in bank credit supply results from a counterfactual experiment that links capital requirements to house prices and mortgage spreads indicate that tighter macroprudential policy would have had a moderating effect on house price and mortgage lending growth in the early 2000s with easier monetary policy acting to offset its contractionary effects on output

absolute abundance and relative scarcity environmental policy with implementation lags we study the effectiveness of environmental policy in a model with nonrenewable resources and an unavoidable implementation lag we find that a time lag between the announcement and the implementation of an emissions quota induces an increase in emissions in the period between the policy s announcement and implementation since a binding constraint on emissions restricts energy use during the implementation phase more of the resources must be extracted outside of it we call this the abundance effect in the case of multiple resources that differ in their pollution intensity a second channel emerges since cleaner sources are relatively more valuable when the policy is implemented it is optimal to conserve them before the cap is enforced this ordering effect tends to induce a switch to dirtier resources before the policy is implemented compounding the increase in emissions via the abundance channel using the announcement lag in title iv of the 1990 caaa as a case study we are able to empirically show that the abundance effect and ordering effect are both statistically and economically significant we discuss a number of alternative policy options to deal with these undesirable side effects of policy announcements
