fdi and taxation a meta study despite the continuing political interest in the usefulness of tax competition and tax coordination as well as the wealth of theoretical analyses it still remains open whether or when tax competition is harmful moreover the influence of tax differentials on multinationals decisions is still insufficiently analyzed thus economists have increasingly resorted to empirical analysis in order to gain insights on the elasticity of fdi with respect to company taxation as a result the empirical literature on taxation and international capital flows has grown to a similar abundance during the last 25 years as the respective theoretical literature its heterogeneity leads to a rising need for concise reviews on the existing empirical evidence in this paper we extend former meta analyses on fdi and taxation in three ways first we add the most recent publications unconsidered in meta analyses up to date second we apply a different methodology by using a broad set of meta regression estimators and explicitly discuss which one is most suitable for application to our meta data third we address some important issues in research on fdi and taxation to the clarification of which meta analysis can make valuable contributions these issues are mainly the influence of variables which might moderate effects of tax differentials e g public spending the implications of using aggregate fdi data as opposed to firm level information on measured tax effects the implications of bilateral effective tax rates and the possible presence of publication bias in primary research

substitution elasticities between ghg polluting and nonpolluting inputs in agricultural production a meta regression abstract this paper reports meta regressions of substitution elasticities between greenhouse gas ghg polluting and nonpolluting inputs in agricultural production which is the main feedstock source for biofuel in the u s we treat energy fertilizer and manure collectively as the polluting input and labor land and capital as nonpolluting inputs we estimate meta regressions for samples of morishima substitution elasticities for labor land and capital vs the polluting input much of the heterogeneity of morishima elasticities can be explained by type of primal or dual function functional form type and observational level of data input categories number of outputs type of output time period and country categories each estimated long run elasticity for the reference case which is most relevant for assessing ghg emissions through life cycle analysis is greater than 1 0 and significantly different from zero most predicted long run elasticities remain significantly different from zero at the data means these findings imply that life cycle analysis based on fixed proportion production functions could provide grossly inaccurate measures of ghg of biofuel

factors explaining local privatization a meta regression analysis this paper aims at explaining the differences in the results of empirical studies of motivations for local privatization by undertaking a meta regression our results suggest that fiscal constraints and interest groups were especially relevant in the early studies of the us which considered several services further studies that focus on one service capture the influence of scale economies more accurately finally our results show that small towns are more affected by fiscal and political factors while ideology plays a major role for european and large cities thus no clear conclusions emerge from this literature because the findings of each study are sensitive to its characteristics

financial development and economic growth a meta analysis we analyze 1334 estimates from 67 studies that examine the effect of financial development on economic growth taken together the studies imply a positive and statistically significant effect but the individual estimates vary widely we find that both research design and heterogeneity in the underlying effect play a role in explaining the differences in results studies that do not address endogeneity tend to overstate the effect of finance on growth while the effect seems to be weaker in less developed countries the effect decreases worldwide after the 1980s our results also suggest that stock markets support faster economic growth than other financial intermediaries

corruption s direct effects on per capita income growth a meta analysis corruption is a symptom of weak institutional quality and could have potentially adverse effects on economic growth however heterogeneity in reported findings makes it difficult to synthesize the evidence base with a view to test competing hypotheses and or support evidence based policy and practice to address this issue we have extracted 327 estimates of corruption s direct effect on per capita gdp growth from 29 primary studies following a peer reviewed and pre published systematic review protocol precision effect and funnel asymmetry tests indicate that corruption has a negative effect on per capita gdp growth after controlling for publication selection bias and within study dependence however multivariate meta regression analysis results indicate that the overall effect is not robust to inclusion of moderating variables through a general to specific procedure for model specification we report that the marginal effect of corruption on per capita gdp growth is more adverse when the primary study estimates relate to long run growth are based on low income country data only and extracted from journal papers the effect is less adverse in studies that use the international country risk guide corruption perceptions index and in those reporting estimates from two stage least squares estimations

menu costs and dynamic duopoly examining a state dependent pricing model in the presence of menu costs and dynamic duopolistic interactions this paper claims that the assumption regarding market structure is crucial for identifying the menu costs for price changes prices in a dynamic duopolistic market can be more rigid than those in more competitive markets such as a monopolistic competition market therefore the estimates of menu costs under monopolistic competition are potentially biased upward due to the price rigidity from strategic interactions between dynamic duopolistic firms by developing and estimating a dynamic discrete choice model with duopoly to correct for this potential bias this paper provides empirical evidence that dynamic strategic interactions as well as menu costs play an important role in explaining the observed degree of price rigidity in weekly retail prices

alcohol consumption and human capital a retrospective study of the literature grossman proposed an individual s health can be viewed as one aspect of their human capital following this line of thought a number of recent papers have reported a positive impact of alcohol consumption on earnings the rationale for the existence of such a relationship is the positive impact of alcohol on physical and mental health we conduct a meta analysis to determine whether such factors as the estimation technique the presence of ex drinkers in the sample possible sample selection bias and publication bias may all contribute to these findings an additional suggestion for the positive relationship between alcohol and wages is the presence of a common set of personality traits that determines drinking behaviour and also leads to higher earnings we examine this relationship by reviewing the literature that investigates if the personality influencing aspects of alcohol consumption influences measures of human capital we also survey the significant body of research that has examined how alcohol consumption has been found to influence educational outcomes and the work force participation of problem drinkers

nonconventional costs of rent seeking x inefficiency in the political process there is relatively little controversy about the expenditures of time and money devoted to lobbying campaign contributions and so on that bias the political process however these traditional rent seeking costs appear to be quite different from nonconventional costs of rent seeking such as those associated with the lack of information about policies that distort the democratic process it is likely that deviations from the ideal pattern of behavior arise not only in markets but also in the democratic process as tullock suggests because voters are not properly informed the problem of identifying waste due to lack of motivation and or information is similar whether in the political arena or in market activities in neither situation is x efficiency observable ex post there will always be situations in which it is obvious that potential opportunities were foregone but to the extent that such wastes either in markets or in the political process cannot be avoided they have no importance for identification of inefficiency or for public policy the conclusion is that x efficiency theory contributes little to our understanding of rent seeking actions by individuals and groups to obtain transfers of wealth through the political process

a meta analysis of the international gender wage gap abstract since the early 1970s a number of authors have calculated gender wage differentials between women and men of equal productivity this meta study provides a new quantitative review of this vast amount of empirical literature on gender wage differentials as it concerns not only differences in methodology data and time periods but also different countries we place particular emphasis on a proper consideration of the quality of the underlying study which is done by a weighting with quality indicators the results show that data restrictions i e the limitation of the analysis to new entrants never marrieds or one narrow occupation only have the biggest impact on the resulting gender wage gap moreover we are able to show what effect a misspecification of the underlying wage equation like the frequent use of potential experience has on the calculated gender wage gap over time raw wage differentials worldwide have fallen substantially however most of this decrease is due to better labor market endowments of females

collusion and price rigidity we consider an in nitely repeated bertrand game in which prices are publicly observed and each rm receives a privately observed i i d cost shock in each period we focus on symmetric perfect public equilibria sppe wherein any punishments are borne equally by all rms we identify a tradeoff that is associated with collusive pricing schemes in which the price to be charged by each rm is strictly increasing in its cost level such fully sorting schemes offer efficiency bene ts as they ensure that the lowest cost rm makes the current sale but they also imply an informational cost distorted pricing and or equilibrium path price wars since a higher cost rm must be deterred from mimicking a lower cost rm by charging a lower price a rigid pricing scheme where a rm s collusive price is independent of its current cost position sacri ces efficiency bene ts but also diminishes the informational cost for a wide range of settings the optimal symmetric collusive scheme requires i the absence of equilibrium path price wars and ii a rigid price if rms are sufficiently impatient however the rigid pricing scheme cannot be enforced and the collusive price of lower cost rms may be distorted downward in order to diminish the incentive to cheat when the model is modi ed to include i i d public demand shocks the downward pricing distortion that accompanies a rm s lower cost realization may occur only when current demand is high

menu costs and phillips curves this paper develops a model of a monetary economy in which individual firms are subject to idiosyncratic productivity shocks as well as general inflation sellers can change price only by incurring a real menu cost we calibrate this cost and the variance and autocorrelation of the idiosyncratic shock using a new u s data set of individual prices due to klenow and kryvtsov the prediction of the calibrated model for the effects of high inflation on the frequency of price changes accords well with international evidence from various studies the model is also used to conduct numerical experiments on the economy s response to various shocks in none of the simulations we conducted did monetary shocks induce large or persistent real responses

prices rise faster than they fall output prices tend to respond faster to input increases than to decreases this tendency is found in more than two of every three markets examined it is found as frequently in producer goods markets as in consumer goods markets in both kinds of markets the asymmetric response to cost shocks is substantial and durable on average the immediate response to a positive cost shock is at least twice the response to a negative shock and that difference is sustained for at least five to eight months unlike past studies which documented similar asymmetries in selected markets gasoline agricultural products etc this one uses large samples of diverse products 77 consumer and 165 producer goods accordingly the results suggest a gap in an essential part of economic theory as a start on filling this gap the study finds no asymmetry in the resonse of an individual decision maker a supermarket chain to its costs but it finds above average asymmetry where a cost shock is filtered through a fragmented w

what s to know about hypothetical bias in stated preference valuation studies abstract hypothetical bias arises in stated preference valuation studies when respondents report a willingness to pay wtp that exceeds what they actually pay using their own money in laboratory or field experiments although this bias is not found in all stated preference surveys hypothetical wtp typically exceeds the actual value by a factor of two to three unfortunately there is no widely accepted general theory of respondent behaviour that explains hypothetical bias therefore two meta analyses are reviewed to test current hypotheses regarding the causes of this overstatement of wtp and the associated recommendations to mitigate the bias suggestions for future research are made including the development of a general theory

successful in the long run a meta regression analysis of persistent firm profits we study the profit persistence literature by applying meta regression analysis mra to a set of 36 empirical papers which analyze the persistence of abnormal firm profits over time the analyzed literature provides evidence for a mediocre degree of persistence in abnormal profits an initial analysis of the distribution of reported profit persistence estimates reveals some degree of excess variation this points toward publication bias that favors significant results independent of their algebraic sign the mra however reveals that publication bias is particularly favoring results that indicate profit persistence and thus contradict the neoclassical model of perfect competition moreover the mra enables to control for heterogeneity driven by the study design we find that the analyzed country developing vs developed the applied econometric approach as well as the analyzed period of time are significant drivers of heterogeneity in reported persistence estimates

demand fluctuations in the ready mix concrete industry i investigate the role of demand shocks in the ready mix concrete industry using census data on more than 15 000 plants i estimate a model of investment and entry in oligopolistic markets these estimates are used to simulate the effect of eliminating short term local demand changes a policy of smoothing the volatility of demand has a market expansion effect the model predicts a 39 increase in the number of plants in the industry since bigger markets have both more plants and larger plants a demand smoothing fiscal policy would increase the share of large plants by 20 finally the policy of smoothing demand reduces entry and exit by 25 but has no effect on the rate at which firms change their size

declining bias and gender wage discrimination a meta regression analysis this paper extends tests and revises a previous meta regression analysis of the gender wage gap stanley and jarrell 1998 we find that there remains a strong though dampened tendency for discrimination estimates to fall and male researchers still report significantly larger amounts of wage discrimination against women this extensive research base containing 104 estimates suggests that there is less need to correct for selection bias an indirect sign of lessened discrimination there is evidence that gender research is changing and improving although gender wage discrimination has lessened the research base still finds a significant gender wage inequality

meta regression analysis a quantitative method of literature surveys abstract pedagogically literature reviews are instrumental they summarize the large literature written on a particular topic give coherence to the complex often disparate views expressed about an issue and serve as a springboard for new ideas however literature surveys rarely establish anything approximating unanimous consensus ironically this is just as true for the empirical economic literature to harmonize this dissonance we offer a quantitative methodology for reviewing the empirical economic literature meta regression analysis mra is the regression analysis of regression analyses mra tends to objectify the review process it studies the processes that produce empirical economic results as though they were any other social scientific phenomenon mra provides a framework for replication and offers a sensitivity analysis for model specification in this brief essay we propose a new method of reviewing economic literature mra and discuss its potential

creating micro marketing pricing strategies using supermarket scanner data micro marketing refers to the customization of marketing mix variables to the store level this paper shows how prices can be profitably customized at the store level rather than adopting a uniform pricing policy across all stores historically there has been a trend by retailers to consolidate independent stores into large national and regional chains this move toward consolidation has been driven by the economies of scale associated with these larger operations however some of these large chains have lost the adaptability of independent neighborhood stores micro marketing represents an interest on the part of managers to combine the advantages of these large operations with the flexibility of independent neighborhood stores a basis for these customized pricing strategies is the result of differences in interbrand competition across stores these changes in interbrand competition are measured using weekly store level scanner data at the product level obviously this presents a huge estimation problem since we wish to measure substitution between each product at a store level for a chain with 100 stores and 10 products in a category we would need to estimate over 100 000 parameters to reliably estimate these individual store differences we phrase our problem in a hierarchical bayesian framework essentially each store level parameter can be thought of as a combination of chain level and random store specific effects the improvement in estimating this model comes from exploiting the common chain level component in addition we relate these store specific changes to demographic and competitive characteristics of the store s trading area which helps explain why these differences are present these estimated differences in price response are in turn used to set store level prices to simplify and focus the problem we limit our attention to everyday price changes i e the prices of products that are not advertised there are many marketing variables that can be adjusted at a storelevel e g promotions and product assortments the reason we concentrate upon everyday pricing is driven by its importance in the marketing mix that most profits are earned on products sold at their everyday price and the amenability of everyday prices to store level customizations a limitation of this approach is that it yields only a partial solution to the retailer s global optimization problem a challenge for the retailer in implementing micro marketing pricing strategies is to retain a consistent image while altering prices that adapt to neighborhood differences in demand our approach is to search for price changes that leave image unchanged we argue that a sufficient condition for holding the input to store image constant from everyday pricing is to hold average price and revenues at their current levels we implement this condition by introducing constraints into the profit maximization problem future research into store choice may yield more efficient conditions a benefit of holding the retailer s image constant is that it does not require costly new information about competitors and promotional activity instead retailers are able to derive these store level customizations based largely upon scanner data this is very advantageous since this information is already being collected and is readily available our results indicate that micro marketing pricing strategies would be profitable and could increase gross profit margins by 4 percent to 10 percent when these gross profit gains are considered after administrative and operating costs are taken into account they could increase operating profit margins by 33 percent to 83 percent these gains come from encouraging consumers through everyday price changes to switch to more profitable bundles of products and not through overall price changes at the chain level these results show that the information contained in the retailer s store level scanner data is an under utilized resource by exploiting this information using newer and more powerful computational techniques managers can better appreciate its value the implication is that profits could be increased and gains can be made by using this information as the basis for micro marketing

patterns in parameters of buyer behavior models generalizing from sparse replication elasticities calculated from estimates of parameters in four consumer behavior system models are pooled in order to assess systematic differences related to variables and to study characteristics the pooling proves to be plausible because the elasticities from particular variable pairings do not vary systematically with study characteristics few elasticities other than those associated with controllable exogenous variables price and distribution differ significantly from the overall mean although the mean elasticity is significantly different from zero the magnitudes of estimated elasticities indicate that the system would tend to converge after being subjected to external shock

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

sticky prices new evidence from retail catalogs this paper presents new results on the size frequency and synchronization of price changes for twelve selected retail goods over the past 35 years three basic facts about the data are uncovered first nominal prices are typically fixed for more than one year although the time between changes is very irregular second prices change more often during periods of high overall inflation third when prices do change the sizes of the changes are widely dispersed both large and small changes occur for the same item and the sizes of these changes do not closely depend on overall inflation

investigating policy and r d effects on environmental innovation a meta analysis in the last decades a wide research effort has been devoted at the analysis of the determinants of environmental innovation ei whereas agreement seemed to emerge around a cluster of determinants mainly technology push market pull policy push pull and firm specific factors empirical analyses have failed to provide strong confirmation on the relevance of some core variables after a qualitative discussion of this literature we empirically assess it by exploiting meta regression analysis techniques to test the effectiveness of two determinants policy and r d our findings are clear as for the first we show that only certain types of policy have proven to affect ei in particular regulatory stringency as for r d we show that the use of estimation methods is not neutral to the outcome of the primary studies

equilibrium exchange rates in central and eastern europe a meta regression analysis abstract this paper analyses the ever growing literature on equilibrium exchange rates in the new eu member states of central and eastern europe in a quantitative manner using meta regression analysis the results indicate that the real misalignments reported in the literature are systematically influenced inter alia by the underlying theoretical concepts balassa samuelson effect behavioral equilibrium exchange rate fundamental equilibrium exchange rate and by the econometric estimation methods the important implication of these findings is that a systematic analysis is needed in terms of both alternative economic and econometric specifications to assess equilibrium exchange rates

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

optimal pricing with costly adjustment evidence from retail grocery prices in many theoretical models it is assumed that there are costs associated with adjusting prices in this paper the existence type and magnitude of such costs are investigated empirically a discrete choice dynamic programming model that nests fixed and variable costs is developed and econometric estimates of the adjustment cost function are obtained the data used to implement the model consist of weekly retail prices and sales of three brands of saltine crackers sold by four chains of grocery stores in a small u s town the study has several distinguishing characteristics first the data are highly disaggregate at the level of brand and store second variables are sampled at weekly intervals third the model nests fixed and variable adjustment costs and can therefore determine their relative importance finally the discrete choice model is both structural and dynamic

the magnitude of menu costs direct evidence from large u s supermarket chains we use store level data to document the exact process of changing prices and to directly measure menu costs at five multistore supermarket chains we show that changing prices in these establishments is a complex process requiring dozens of steps and a nontrivial amount of resources the menu costs average 105 887 year per store comprising 0 70 percent of revenues 35 2 percent of net margins and 0 52 price change these menu costs may be forming a barrier to price changes specifically 1 a supermarket chain facing higher menu costs due to item pricing laws that require a separate price tag on each item changes prices two and one half times less frequently than the other four chains 2 within this chain the prices of products exempt from the law are changed over three times more frequently than the products subject to the law in principle fixed costs of changing prices can be observed and measured in practice such costs take disparate forms in different firms and we have no data on their magnitude so the theory can be tested at best indirectly at worst not at all alan blinder 1991 p 90

the dynamics of markups and inventories in retailing firms this paper is concerned with the interaction between price and inventory decisions in retailing firms and its implications for the dynamics of markups and the existence of sales pro motions we consider a model where a monopolistically competitive retailer decides price and inventories and assumes lump sum costs when placing orders or changing nominal prices tn this model the existence of stockout probabilities and fixed ordering costs generate a cyclical price behaviour characterized by long periods without nominal price changes and short periods with very low prices i e sales promotions we estimate this model using a unique longitudinal dataset with information about retail and wholesale prices inventories orders and sales for several brands in a supermarket chain based on the estimated model we perform several counterfactual experi ments that show the important role that inventories and fixed ordering costs play in the dynamics of retail prices and the frequency of sales promotions in this dataset

switching costs in frequently repeated games abstract we add small costs of changing actions and frequent repetition to finitely repeated games making some surprising commitments credible naturally switching costs make it credible not to change action however this can occur for small switching costs and gives a unique subgame perfect equilibrium in coordination games when pareto dominance and risk dominance coincide in the prisoners dilemma switching costs reduce the incentive to deviate from mutual cooperation but reduce the incentive to switch from cooperation to punish defection hence whether switching costs enable cooperation depends on which effect dominates switching costs can make complex threats credible enabling a player to earn more than his stackelberg payoff journal of economic literature classification numbers c7 c73

is the environmental kuznets curve for deforestation a threatened theory a meta analysis of the literature abstract although widely studied deforestation remains a common research topic the relationship between economic development and deforestation is still in question this paper presents a meta analysis of environmental kuznets curve ekc studies for deforestation using 69 studies offering 547 estimations we shed light on why ekc results differ we investigate the incidence of choices made by authors such as econometric strategy measure of deforestation geographical area and presence of control variables on the probability of finding an ekc after a phase of work corroborating the ekc we find a turning point after the year 2001 building on our results we conclude that the ekc story will not fade until theoretical alternatives are provided

the rigidity of prices this paper uses evidence on individual transaction prices to analyze price behavior the evidence shows that for many transactions pricesremain rigid for periods exceeding one year the rigidity of price ispositively correlated with industry concentration for several productsthe correlation of price changes across buyers is low the paper alsoinvestigates the relationship between price rigidity price change andthe length of time a buyer and seller have been doing business together the author interprets the evidence as emphasizing the importance of nonprice rationing and the inadequacy of models in whichprice movements alone clear markets copyright 1986 by american economic association

sticky prices in a dynamic oligopoly an investigation of s s thresholds abstract the strategic implications of costly price adjustment are investigated empirically i assume that managers are engaged in a state space game and ask if the dynamic considerations that arise when they condition their choices on the state cause prices to be more or less rigid than when players use more myopic pricing rules the answer to this question depends on a parametric specification of the problem that lends itself to empirical assessment the micro panel data used to investigate this issue consist of weekly prices sales costs and promotional activity for three brands of saltine crackers sold by four chains of grocery stores in a small us town i find that in this market strategic behavior exacerbates price rigidity the thresholds are wider and the time between changes is longer than would be observed in a more myopic setting

a meta analysis on the price elasticity and income elasticity of residential electricity demand abstract price elasticity and income elasticity can quantitatively measure the impact of price volatility and income diversity on household electricity demand to analyze household electricity demand and better identify the main factors affecting residential electricity demand elasticity in previous literature a meta analysis based on a comprehensive and systematic summary of 103 articles is presented in this study the influencing factors are identified with a weighed least squares wls linear regression model to evaluate their strength the price elasticities and income elasticities are discussed from three dimensions namely short term long term and unmarked the results show that residential electricity demand is almost price inelastic and income inelastic in the short term but in the long term some residential electricity demand is price elastic and income elastic the results also reveal that residential electricity demand elasticity is affected by many factors such as time interval and sample period these conclusions can support the formulation of more effective electricity price and energy policy

accounting for incomplete pass through recent theoretical work has suggested a number of potentially important factors in causing incomplete pass through of exchange rates to prices including markup adjustment local costs and barriers to price adjustment we empirically analyze the determinants of incomplete passthrough in the coee industry the observed pass through in this industry replicates key features of pass through documented in aggregate data prices respond sluggishly and incompletely to changes in costs we use microdata on sales and prices to uncover the role of markup adjustment local costs and barriers to price adjustment in determining incomplete pass through using a structural oligopoly model that nests all three potential factors the implied pricing model explains the main dynamic features of short and long run pass through local costs reduce long run pass through by a factor of 59 relative to a ces benchmark markup adjustment reduces pass through by an additional factor of 33 where the extent of markup adjustment depends on the estimated super elasticity of demand the estimated menu costs are small 0 23 of revenue and have a negligible eect on long run pass through but are quantitatively successful in explaining the delayed response of prices to costs we nd that delayed passthrough in the coee industry occurs almost entirely at the wholesale rather than the retail level

a dynamic oligopoly with collusion and price wars we provide a collusive framework with heterogeneity among jirms investment entry and exit it is a symmetric information model in which it is hard to sustain collusion when there is an activejim that is likely to exit in the near future numerical analysis is used to compare a collusive to a noncollusive environment only the collusive industry generates price wars also the collusive industry offers both more and higherquality products to consumers albeit often at a higher price the positive effect of collusion on variety and quality more than compensates consumers for the negative effect of collusive prices so that consumer surplus is larger with collusion

x efficiency rent seeking and social costs this paper investigates shifts in cost functions of monopoly and regulated firms operating under conditions of x inefficiency and rent seeking behavior we show that x inefficiency and rent seeking have significantly different implications for economic welfare distinctions are drawn between pecuniary and real x inefficiency and between sunk and continuing rent seeking costs in general for a given cost shift rent seeking behavior implies larger social costs than does x inefficiency theory however cost shifts caused by either x inefficiency or rent seeking are observationally equivalent this implies empirically measured cost shifts cannot unambiguously be attributed to either cause

state dependent pricing and the general equilibrium dynamics of money and output economists have long suggested that nominal product prices are changed infrequently because of fixed costs in such a setting optimal price adjustment should depend on the state of the economy yet while widely discussed statedependent pricing has proved difficult to incorporate into macroeconomic models this paper develops a new tractable theoretical state dependent pricing framework we use it to study how optimal pricing depends on the persistence of monetary shocks the elasticities of labor supply and goods demand and the interest sensitivity of money demand

meta analysis of empirical evidence on energy poverty the case of developing economies abstract energy poverty has evolved as an important issue of research from academic and policy perspectives during the last two decades the energy poverty estimates exhibit widespread variations across regions methodologies and datasets making the task of energy and development policies challenging the variations in energy poverty estimates necessitate a systematic and rigorous analysis of these empirical studies to obtain a true measure of energy poverty the present study conducts a meta analysis of 30 studies and 103 estimates of energy poverty on average 71 1 percent of the population in the overall sample studies has been identified as energy poor high i square statistic values suggest heterogeneity bias in the sample studies therefore analysis at the subgroup level has been conducted meta regression analysis of overall sample and subgroups has identified type of methodology citations impact factor of the journal regional dummies average key crude oil price and gross domestic product as significant factors that explain heterogeneity in the energy poverty effect sizes we recommend inclusion of local and regional factors in assessment of energy poverty for developing a uniform methodology to assess energy poverty across developing economies

replication in empirical economics the journal of money credit and banking project this paper examines the role of replication in empirical economic research it presents the findings of a two year study that collected programs and data from authors and attempted to replicate their published results the research provides new and important information about the extent and causes of failures to replicate published results in economics the findings suggest that inadvertent errors in published empirical articles are a commonplace rather than a rare occurence copyright 1986 by american economic association

the effects of exchange rate variability on international trade a meta regression analysis the trade effects of exchange rate variability have been an issue in international economics for the past 30 years the contribution of this article is to apply meta regression analysis mra to the empirical literature on average exchange rate variability exerts a negative effect on international trade yet mra confirms the view that this result is highly conditional by identifying factors that help to explain why estimated trade effects vary from significantly negative to significantly positive mra evidence on the pronounced heterogeneity of the empirical findings may be instructive for policy first by establishing that average trade effects are not sufficiently robust to generalize across countries and second by suggesting the importance of hedging opportunities hence of financial development for trade promotion for the practice of mra we make a case for checking the robustness of results with respect to estimation technique model specification and sample
