fixed production capacity menu cost and the output inflation relationship this paper analyses the impact of inflation when firms face frictions in both price and quantity adjustments a vast literature examines the consequences of price adjustment costs assuming frictionless quantity adjustments however temporary quantity adjustments may be expensive for example because continual adjustments of the optimal production plant are impossible moreover recent findings suggest that frictions in quantity adjustment may remove the linkage between output and inflation in this paper we show that this is not the case when inflation is anticipated on the contrary a predetermined production capacity may significantly amplify the consequences of price adjustment costs

mutual supervision in preshipment inspection programs abstract preshipment inspection psi programmes are implemented in many developing countries to assist governments in the collection of revenue at their borders these programs consist of the delegation of the inspection of imports to a private firm to study these psi programmes we develop a hierarchical agency model in which the government authority can rely on two supervisors namely the private inspection firm and the customs administration to control importers declarations the government s optimal contract is fully characterized we devote some attention to the inspection policy and its comparative statics properties in particular we identify the situations in which psi programmes are revenue enhancing we also discuss the reconciliation policy i e what to do in case of conflicting inspection reports by the inspection firm and the customs administration in the optimal mechanism mutual supervision between the inspection firm and the customs administration is used to provide adequate incentives to all parties

adapting prices or quantities in the presence of adjustment costs it is often hypothesized that costs of adjusting both price and quantities may have important implications for the macroeconomic adjustment process not least to nominal shocks we analyse this in an explicit intertemporal general equilibrium model considering the empirically relevant case of fixed costs of adjusting prices and fixed and variable costs of adjusting quantities we find that the presence of both price and quantity adjustment costs changes the response to shocks significantly it is an implication that small shocks do not support the menu cost case but rather both fixed prices and quantities rationing a numerical analysis based on available evidence on adjustment costs is used to illustrate the likelihood that the various adjustment patterns actually arise

trade policy making in a small island economy the wto review of the maldives the purpose of this paper is to examine trade policy regime and trade related development issues in the maldives on the basis of the trade policy review maldives 2003 of the wto the key theme of the paper is that given the narrow resource base and small domestic market openness to foreign trade and investment remains the natural policy choice for a small developing economy like the maldives since the late 1980s the maldivian government has made considerable progress in implementing policy reforms driven by this conviction however the reform process is far from complete high import tariffs maintained predominantly on revenue considerations a large direct role played by the public sector in foreign trade and some key sectors of the economy lack of transparency in duty concessions and other investment incentives failure to incorporate environmental concerns as part of the national development policy and delays in meeting reform commitments under the wto are among the key items of the unfinished reform agenda

a large scale mapping of territorial development dynamics in latin america summary this paper summarizes a study of changes in per capita income monetary poverty and income distribution in 9 045 subnational administrative units of nine latin american countries between the mid 1990s and mid 2000s the results largely support spatial convergence of mean household incomes although the estimates indicate it has been slow territorial inequality is found to be persistent and reduces the pro poor effect of local income growth although national context specific the estimates also indicate that territorial development dynamics are influenced by the structural features of the territories in view of the evidence territorial development policies in latin america seem well warranted

bertrand equilibria with entry limit results abstract we study the limiting behaviour of bertrand equilibria where firms must supply the whole of the demand coming to them for two different cases first when entry is exogenous and second when it is free the limit equilibrium set is characterised for both cases for a large class of cost functions

how business is done in the developing world deals versus rules what happens in the developing world when stringent regulations characterizing the investment climate meet weak government willingness or capability to enforce those regulations how is business actually done the doing business project surveys experts concerning the legally required time and costs of regulatory compliance for various aspects of private enterprise starting a firm dealing with construction permits trading across borders paying taxes getting credit enforcing contracts and so on around the world the world bank s firm level enterprise surveys around the world ask managers at a wide array of firms about their business including questions about how long it took to go through various processes like obtaining an operating license or a construction permit or bringing in imports this paper compares the results of three broadly comparable indicators from the doing business and enterprise surveys overall we find that the estimate of legally required time for firms to complete a certain legal and regulatory process provided by the doing business survey does not summarize even modestly well the experience of firms as reported by the enterprise surveys when strict de jure regulation and high rates of taxation meet weak governmental capabilities for implementation and enforcement we argue that researchers and policymakers should stop thinking about regulations as creating rules to be followed but rather as creating a space in which deals of various kinds are possible

when does growth trickle down to the poor the indian case a theoretical analysis and several econometric tests have been undertaken to examine whether the trickle down effect took place in rural india over a long time period we found little evidence to suggest that the trickle down effect had occurred at all our analysis suggests that the emergence of capital labour substitution was primarily responsible for preventing growth from reducing poverty the decline in poverty and a higher growth rate that took place during the late 1970s and 1980s were largely a result of government anti poverty measures teamed with the more equitable distribution of credit and inputs to smaller and marginal farmers

inflation costly price and quantity adjustments and time spent in the keynesian regime abstract this paper considers a menu cost firm under inflation due to costly quantity adjustments the firm is sometimes in a keynesian regime where sales are demand determined with a positive real interest rate the proportion of time in the keynesian regime is less than the inverse of the absolute value of the average elasticity of demand in that regime

the cyclical behavior of prices abstract the procyclical behavior of prices has been a staple of business cycle lore since the work of the early nber business cycle researchers this paper reexamines that empirical fact the aggregate data do not support procyclical price movements as a stable feature of the business cycle the only episode where it is a robust feature of the data is the period between the two world wars particularly the period of the great depression

the impact of transport and transaction cost reductions on food markets in developing countries evidence for tempered expectations for burkina faso reductions in transport and transaction costs are expected to have a major effect on the functioning of food markets in developing countries for burkina faso this is a relevant issue as it may have important consequences for the food markets in urban and rural deficit areas a partial equilibrium model is presented to analyze the short term effects of reduced costs on price formation inter regional cereal trade and farmers and traders storage strategies our results show that the high expectations with regard to the direct effects of cost reductions on food prices and food availability require some nuance the effects of a reduction of transport costs will be small moreover also the unintended negative consequences on the competitive position of farmers and traders in other regions that do not profit from road construction should be taken into account finally it is concluded that only if transport and transaction costs are reduced simultaneously will both the consumers and farmers benefit significantly c 2004 elsevier b v all rights reserved

adjustment costs inventories and output this paper analyzes the optimal adjustment strategy of an inventory holding firm facing price and quantity adjustment costs in an inflationary environment the model nests both the original menu cost model that allows production to be costlessly adjusted and the later model that includes price and quantity adjustment costs but rules out inventory holdings it is shown that the firm s optimal adjustment strategy may involve stockouts at low inflation rates output is inversely related to the inflation rate and the length of time demand is satisfied increases with the demand elasticity but decreases with the storage cost and the real interest rate

causal relationships between public sector agricultural research expenditures and output allocative decisions concerning public sector agricultural research appear to be driven by both supply and politically mediated demand forces in sample granger tests along with post sample predictive tests suggest that simultaneity issues should not be ignored when modeling the research expenditure output relationship the results also provide strong evidence that the impact of research expenditures on agricultural output may persist for as long as thirty years these lags are substantially longer than those commonly used for agricultural research to date the lagged effect of output on research appears to be shorter though still between ten and twelve years in this article we analyze the empirical relationship between public sector agricultural research and agricultural output our interest in this question was spurred on two fronts first emphasis of the contemporary economic literature has shifted from an analysis of the consequences of technical change to an explanation of the observed rate and direction of inventive activity a substantial proportion of this literature has focused on appropriable technologies originating in the private sector and remained largely silent on related issues in the public sector here we analyze the dynamics of public sector research in particular publicly sponsored agricultural research in the

globalization and rural poverty as is common in most contentious public debates different people mean different things by globalization some interpret it to mean the global reach of new technology and capital movements some refer to outsourcing by domestic companies in rich countries others protest against the tentacles of corporate capitalism or us hegemony economic military or cultural in this chapter i shall limit myself to interpreting globalization simply as openness to foreign trade and long term capital flows i shall ignore here the important issues arising from the devastation caused to fragile economies by billions of dollars of volatile short term capital stampeding around the globe in herd like movements or the substantial poverty reducing potential of international unskilled labour flows from poor to rich countries even if allowed in temporary and regulated doses

unpacking the meaning of market access evidence from rural kenya summary this paper critically examines the dimensions of market access using farm panel survey data from kenya we investigate changes in ten indicators of market access during the 1997 2010 post liberalization period we find major improvements in certain market access conditions and little change in others there is generally low correlation between alternative indicators of market access all purpose indicators may not accurately reflect specific market access conditions of interest distances to physical infrastructure are often not representative of farmers access to markets changes in specific market access conditions may have more to do with the behaviors of marketing agents we consider the implications of these findings for agricultural marketing policies and for research methods

sticky price models of the business cycle can the contract multiplier solve the persistence problem we construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations these fluctuations include persistent movements in output along with the other defining features of business cycles like volatile investment and smooth consumption we assume that prices are exogenously sticky for a short time persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so we find that for a wide range of parameter values the amount of endogenous stickiness is small thus we find that in a standard quantitative model staggered price setting alone does not generate business cycle fluctuations

a genral model of dynamic labor demand this study derives and estimates a dynamic model of factor demand that includes both fixed and quadratic variable costs of adjustment using quarterly data on the employment of mechanics at seven airlines it finds that both types of adjustment costs characterize the dynamic constraints facing employers using monthly data covering production worker employment in seven manufacturing plants it shows that only fixed costs are important the apparent diversity of the underlying costs of adjustment means it is difficult to draw useful inferences from macroeconometric estimates it suggests the importance of examining broader arrays of microeconomic time series describing labor demand this abstract was borrowed from another version of this item

costs of price adjustment and the welfare economics of inflation and disinflation this paper studies the welfare consequences of inflation and disinflation in a model in which monopol istic firms incur a fixed cost of price adjustment it is shown that a moderately increasing price level is associated with higher social welfare than a perfectly stable price level and the model therefore provides theoretical support for the widespread belief that a little bit of inflation is good for the economy nevertheless it is also tr ue that the eradication of a moderate inflation leads to an increase in social welfare copyright 1988 by american economic association

output fluctuations at the plant level this paper examines the short run dynamics of manufacturing costs by detailing how plants in the u s automobile industry change output weekly data show a variety of margins on which firms adjust production these margins which are distinct from the usual factor demand choices differ in their lumpiness their adjustment costs and their variable costs the existence of these margins explains several empirical puzzles of output fluctuations using a theory of the short run dynamic cost function we are able to infer some of the characteristics of the underlying cost function from the dynamic behavior of the different margins

measuring protection mission impossible abstract there seems to be some confusion between openness and protection measures in the international trade literature the aim of this paper is to bring together the state of the art in quantifying trade policy measures and for this reason we focus on the extent of the protection granted by policies rather than on the degree of openness of the economy given the considerable amount of literature that deals with these issues we will limit our review as follows on the one hand we focus on trade policies implemented at the border and therefore do not consider all the other possible public interventions influencing trade flows on the other hand we only take into account indexes that explicitly adopt a metric expressed in a scalar aggregate tariff and quota equivalent measures or an index in a closed interval we distinguish between indexes that aggregate across products same barrier for more products and indexes that aggregate across instruments more barriers for the same product finally in order to classify the large number of indexes covered in our review we propose a typology based on three categories incidence outcome and equivalence

regionalism and the bias against agriculture in less developed countries panel survey data play a crucial role in producing estimates on welfare dynamics as well as insights into transformation processes in developing economies panel survey data are indispensable for effective policy advice for poverty reduction and growth fielding and maintaining a good quality panel survey requires investment in financial and technical resources as well as careful planning especially in developing countries statistical techniques can also be employed to produce estimates on poverty dynamics as an alternative methodology but a new hybrid approach can combine the advantages of both methods

differentiated products and evasion of import tariffs emerging literature has demonstrated some unique characteristics of trade in differentiated products this paper contributes to the literature by postulating that differentiated products may be subject to greater tariff evasion due to the difficulties associated with assessing their quality and price using product level data on trade between germany and 10 eastern european countries during 1992 2003 the authors find empirical support for this hypothesis they show that the trade gap defined as the discrepancy between the value of exports reported by germany and the value of imports from germany reported by the importing country is positively related to the level of tariff in 8 out of 10 countries further the authors show that the responsiveness of the trade gap to the tariff level is greater for differentiated products than for homogeneous goods a one percentage point increase in the tariff rate is associated with a 0 6 percent increase in the trade gap in the case of homogeneous products and a 2 1 percent increase in the case of differentiated products finally the data indicate that greater tariff evasion observed for differentiated products tends to take place through misrepresentation of the import prices

the economic and poverty impacts of maize research in west and central africa this article assembles the results of three multicountry surveys on variety performance and adoption patterns to measure the impacts of maize research in west and central africa from 1981 to 2005 and uses cost data since 1971 to compute social rates of return on public investments in maize research in the region adoption of modern varieties increased from less than 5 of the maize area in the 1970s to about 60 in 2005 yielding an aggregate rate of return on research and development r d investment of 43 the estimated number of people moved out of poverty through adoption of new maize varieties rose gradually in the 1980s to more than one million people per year since the mid 1990s over half of these impacts can be attributed to international maize research at iita and cimmyt the article concludes with a discussion of strategic options to enhance the impacts of maize research in the region

rural poverty and relative prices in india this paper begins with the observation that there has been a trend decline albeit small in rural poverty during 1956 83 but this is obscured by the substantial short run fluctuations around the trend it argues that while the trend is attributable to redistributive policies the short run fluctuations are adequately explained by the fluctuations in agricultural output and in relative prices of agricultural products vis a vis manufactures in view of the finding that rising relative agricultural prices increase rural poverty the paper goes on to analyze the process of determination of relative prices this analysis highlights the characteristics of the inflationary process and the role of agricultural price policy in the indian economy copyright 1989 by oxford university press

ethnic diversity and poverty we examine the relationship between ethnic diversity and poverty for a cross sectional sample of developing countries we measure diversity using indices of ethnic and linguistic fractionalization and measure poverty using the multidimensional poverty index mpi multidimensional poverty headcount mph intensity of deprivation poverty gap and poverty headcount ratio we find that ethnic and linguistic fractionalization contributes to poverty levels specifically after controlling for endogeneity we find that a standard deviation increase in ethnic fractionalization is associated with a 0 32 0 44 and 0 53 standard deviation increase in the mpi mph and the intensity of deprivation respectively moreover a standard deviation increase in ethnic fractionalization is associated with between a 0 34 and 0 63 standard deviation increase in the population living below 1 90 and 3 10 the poverty gap at 1 90 and 3 10 a day and the headcount ratio at 1 90 and 3 10 a day similar results are also observed for linguistic fractionalization with standardized coefficients between 0 53 and 0 93 we find that our results are robust to alternative ways to measure poverty and ethnic diversity including ethnic polarization as well as alternative approaches to address endogeneity

population growth and poverty another look at the indian time series data previous studies of the time trend of rural poverty in india agree in assuming that population size does not influence poverty independently of per capita agricultural output the article examines this assumption for the 1959 160 to 1970 71 period using a pooled model with variable slope coefficients to avoid the problem of collinearity between population estimates and time the results suggest that poverty in india during 1960s was a function of both agricultural production and population but that the properties of this function are significantly different from those generally posited

targeting public investments by agro ecological zone to achieve growth and poverty alleviation goals in rural india abstract this paper shows that improved technology and rural infrastructure have made important contributions to agricultural growth and poverty reduction in india however these effects have varied widely across agro ecological zones in the past the government has devoted more resources to irrigated areas and this has led to significant production growth and poverty reduction in those areas however as investments in irrigated areas continue to increase their marginal returns diminish and it is now in many of the rainfed areas including some of lower agricultural potential where the marginal returns from additional government investments in technology and infrastructure are largest

output and welfare effects of inflation with costly price and quantity adjustments there exists by now a burgeoning literature concerned with the consequences of a fixed cost of price adjustment due to this cost a monopolistic firm does not necessarily adjust its price even though the current price deviates from the price that would maximize the firm s current profit as a result the production generally differs from what it would be in the absence of a menu cost with the effect of inflation on the average output and welfare under monopolistic competition being ambiguous and depending in a complicated way on the profit and demand functions 1 however one strong result holds unambiguously for all profit and demand functions at low inflation rates the average output and welfare are above their levels at full price stability where firms charge the static monopoly price 2 the driving force is that discounting makes a firm more concerned with its real profits earlier in a period with a constant nominal price than with its real profits later in the period in fact as the inflation rate approaches zero the firm s initial real price converges to the profit maximizing real price while the terminal real price converges to a smaller real price at low inflation rates therefore a firm s price is most of the time below the price that would maximize the current profit since output and welfare under monopolistic competition are inversely related to price average output and welfare are higher than under full price stability the inevitable conclusion is that the economy benefits from a little bit of inflation a critical assumption underlying this result is that firms can continuously adjust their production to satisfy demand so while the menu cost literature explicitly assumes that there is a small fixed cost incurred at each price adjustment it also implicitly assumes that it is costless to continuously adjust the quantity of output 3 this is however a questionable assumption there is some empirical evidence indicating the existence of a cost of quantity adjustment part of which is fixed in that it does not depend on the size of the adjustment 4 the cost of quantity adjustment stems from the need to rearrange and reorganize the factor inputs for the new level of production and includes managerial time and effort a fixed cost of quantity adjustment rules out any continuous adjustment of the production to satisfy the increasing demand that results from a decreasing real price within a period with a constant nominal price under the reasonable assumption that the menu cost does not exceed the fixed cost of quantity adjustment 5 in an inflationary environment a firm chooses to adjust its nomi

revenue erosion through exemption and evasion in cameroon 1993 abstract the administration of tax statutes materially determines their economic effects a survey of cameroonian businesses a country seemingly typical of its economic level demonstrates widespread erosion of the tax bases paid by businesses through exemptions and evasion businesses seem willing to provide information on these potentially confidential activities the survey provides information on the number of businesses evading taxes or having exemptions on the characteristics of these businesses relative to others on whether businesses maintain information of use to the tax administration on the contacts between the administration and businesses affecting evasion and on penalties imposed by the administration

how does india s rural roads program affect the grassroots findings from a survey in orissa this paper analyzes the effects of all weather rural roads on households net output prices education and health in a poor drought prone region of india of 30 villages originally surveyed in 2001 02 when two had such roads a further nine received them between january 2007 and december 2009 under the program pradhan mantri gram sadak yojana cross section comparisons involving all villages and before and after comparisons in the nine yielded these findings i net output prices were 5 per cent or more higher ii substantially fewer days of schooling were lost due to bad weather largely because teachers had fewer absences iii the acutely sick received more timely treatment and were more likely to be treated in a hospital than in the nearest primary health clinic and iv the respondents ranked the resulting benefits in the domains of health and education at least as highly as the commercial ones

output effects of inflation with fixed price and quantity adjustment costs i introduction there is convincing evidence that fixed costs of price adjustment may be large levy et al 1997 found such costs to be 0 7 of a firm s revenue and zbaracki et al 2004 found them to be 1 22 in the presence of fixed costs of price adjustment a monopolistic firm does not adjust its nominal price continuously with the result that the real price and output generally deviate from their static monopoly level at low inflation rates the average output is higher than the static monopoly output if there is positive discounting danziger 1988 and depends on higher order derivatives of the profit and demand functions if there is no discounting benabou and konieczny 1994 1 most of the literature assumes that only price adjustments are costly while output can be continuously adjusted without cost however bresnahan and ramey 1994 document that there may be large fixed costs of quantity adjustments relatedly many publications show that adjusting labor and capital inputs involves significant fixed costs 2 such costs may derive from loss of organizational capital baily et al 2001 jovanovic and rousseau 2001 as well as from job protection rules severance pay and legal and administrative complications in a framework with both price and quantity adjustment costs andersen 1995 and andersen and toulemonde 2004 demonstrate that only intermediate size shock but not large or small shocks may affect output for a constant inflation rate danziger 2001 shows that a firm s permanent production decreases with inflation at low inflation rates if discounting is positive and danziger and kreiner 2002 that output capacity decreases with inflation if the elasticity of demand is constant and there is no discounting see also danziger 2003 the purpose of this article is to provide a simple general characterization of the output effects of a constant inflation rate if both price and quantity adjustments involve fixed costs it is assumed that quantity adjustments are at least as costly as price adjustments which implies that a firm s production is held constant at a permanent level 3 each firm then keeps its nominal price unchanged in periods of equal length and the nominal price is adjusted so that the initial real price is the same in each period thus a firm s optimal strategy consists of the initial real price the duration of the periods with unchanged nominal price and the permanent level of production the article shows that in the absence of discounting the effect of inflation on the aggregate production depends on how fast firms marginal real revenue decreases with demand and that this effect is fully determined by the elasticity of the marginal real revenue with respect to demand thus aggregate production decreases with inflation if the elasticity of the marginal real revenue always exceeds minus unity increases with inflation if the elasticity of the marginal real revenue is always less than minus unity and is invariant to inflation if the elasticity of the marginal real revenue always equals minus unity several studies have found that the comovement between output and prices is typically negative in the long run cooley and ohanian 1991 den haan 2000 den haan and sumner 2004 fiorito and kollintzas 1994 within the framework of the present model the negative comovement indicates that the empirically relevant situation is when the elasticity of the marginal real revenue always exceeds minus unity this will be the case among others if demand functions exhibit a constant price elasticity less than minus unity as assumed in danziger and kreiner 2002 ii the model consider an economy with a unit continuum of identical consumers and a unit continuum of monopolistic firms producing differentiated perishable products each firm and its product are indexed by i which is uniformly distributed on 0 1

tax rates and tax evasion evidence from missing imports in china tax evasion by its very nature is difficult to observe we quantify the effects of tax rates on tax evasion by examining the relationship in china between the tariff schedule and the evasion gap which we define as the difference between hong kong s reported exports to china at the product level and china s reported imports from hong kong our results imply that a one percentage point increase in the tax rate is associated with a 3 percent increase in evasion furthermore the evasion gap is negatively correlated with tax rates on closely related products suggesting that evasion takes place partly through misclassification of imports from higher taxed categories to lower taxed ones in addition to underreporting the value of imports

adjustment costs and price and quantity adjustment abstract the role of prices and quantities in the adjustment process changes qualitatively when both price and quantity adjustment are costly not only relative adjustment costs but also structural characteristics affect the adjustment process which is asymmetric and implies rationing

a century of economic growth in latin america abstract this paper makes a contribution to the study of economic growth in developing countries by analyzing the six largest latin american economies over 105 years within a two equation framework confirming previous findings physical and human capital prove to be key determinants of gdp per head growth however a more controversial result is an overall negative conditional correlation between trade openness and gdp per head growth though openness has a positive link via investment the evidence also shows that macroeconomic instability has been a drag on long term growth in the region

growth inequality and poverty looking beyond averages the evidence is compelling that the poor in developing countries do typically share in the gains from rising aggregate affluence and in the losses from aggregate contraction but how much do poor people share in growth do they gain more in some settings than others do some gain while others lose does pro poor growth mean more or less aggregate growth recent theories and evidence suggest some answers but deeper microeconomic empirical work is needed on growth and distributed change only then will we have a firm basis for identifying the specific policies and programs needed to complement and possibly modify growth oriented policies

bertrand edgeworth equilibria with unobservable output uncoordinated consumers and large number of firms abstract we examine a bertrand edgeworth model of price competition where the output levels of the firms are unobservable and consumers are uncoordinated we show that if the number of firms is large enough then any price greater than the competitive one can be sustained as a pure strategy nash equilibrium

gaining more by stocking less a competitive analysis of product availability the price competition between two firms can affect their decisions about product availability with occasional stockouts a firm loses from foregone sales yet it may indirectly benefit from the higher price a competitor is able to charge the more prone customers are to search elsewhere for the product upon encountering a stockout the greater is the gain from the reduced price competition between firms this paper establishes conditions whereby the strategic interaction of reduced price competition between firms outweighs the loss from foregone sales in such cases a firm can increase its expected profits by choosing to stock less these results provide a competitive rationale for the high stockout levels observed in some retail situations and have implications for the analysis of product availability in public policy settings

production prices and poverty in rural india this paper challenges the view that increases in agricultural production have reduced poverty in rural india rural poverty is related directly to the consumer price index number for agricultural labourers and inversely to agricultural production the underlying time trend term indicates a residual rising trend in rural poverty after accounting for the influence of these two factors there are plausible though conjectural reasons for believing that to a significant extent the price factor as well as the variables implicit in the time trend term both derive their strength if not their existence from the nature of the growth processes which have generated the observed growth in agricultural production these results contradict ahluwalia s earlier conclusions even though they are themselves based on essentially the same data set

the comovement between real activity and prices in the g7 in this paper we study the short run and long run comovement between prices and real activity in the g7 countries during the postwar period using var forecast errors and frequency domain filters we find several patterns of the correlation coefficients that are robust across countries and time periods typically the correlation coefficients at long run horizons are significantly negative and the correlation coefficients at short run horizons are substantially higher additionally there is evidence of positive correlation at short run forecast horizons for some countries

government spending growth and poverty in rural india using state level data for 1970 93 a simultaneous equation model was developed to estimate the direct and indirect effects of different types of government expenditure on ruralpoverty and productivity growth in india the results show that in order to reduce rural poverty the indian government shoul d give highest priority to additionalinvestments in ruralroads and agricul turalresearch these types of investment not only have much larger poverty impacts per rupee spent than any other government investment but also generate higher productivity growth apart from government spending on education which has the third l argest marginalimpact on ruralpoverty and produc

poverty agricultural production and prices in rural india a reformulation the empirical analysis at the all india level demonstrates that while the level of agricultural production and rural poverty were inversely related unanticipated consumer price increases aggravated rural poverty whether the advent of the new agricultural technology in the late 1960s altered the relationships in question is also considered during the new technology phase the coefficient of agricultural production ceased to be significant while that of unanticipated price changes continued to be significant rationalization of the absence of a significant inverse relationship between rural poverty and agricultural production at the state level in terms of distress migration between neighboring states is questioned and an alternative explanation is provided copyright 1989 by oxford university press

the mercantilist index of trade policy we introduce an index of trade policy restrictiveness defined as the uniform tariff that maintains the same trade volume as a given tariff quota structure our index overcomes the problems of the trade weighted average tariff it avoids substitution bias correctly accounts for general equilibrium transfers and takes import volume instead of welfare as benchmark empirical applications to international cross section and time series comparisons of trade policy confirm our theoretical results trade weighted average tariffs generally underestimate the true height of tariffs as measured by the trade volume equivalent index this in turn always underestimates the welfare equivalent index

contract adjustment under uncertainty abstract consider trade in continuous time between two players the gains from trade are divided according to a contract and at each point in time either player may unilaterally induce a costly adjustment of the contract players payoffs from trade under the contract as well as from trade under an adjusted contract are exogenous and stochastic we consider players choice of whether and when to adjust the contract payment we show that there exists a nash equilibrium in thresholds where each player adjusts the contract whenever the contract payment relative to the outcome of an adjustment passes the threshold there is strategic substitutability in the choice of thresholds so that if one player becomes more active by choosing a threshold closer to unity the other player becomes more passive

estimating border tax evasion in mozambique abstract the relationship between border tax rates and evasion is examined for mozambique using the methodology developed by fisman and wei 2004 we find that high tax rates are associated with high levels of under reporting of import values and that tax rates have a strong and positive effect on tax evasion results also strongly confirm the presence of fraudulent classification of merchandise into lower taxed product categories finally analysis of the revenue implications of lower trade taxes finds that the revenue curve is quite flat but remains upward sloping with respect to the tax rate when only evasion is considered

wage premia price cost margins and bargaining power in belgian manufacturing abstract an asymmetric nash bargaining model as developed by j svejnar 1986 is empirically tested on industry wage negotiations in belgium union s relative bargaining power emerges from this model as the fraction of firm s profits per worker which the unions are able to capture in excess of the alternative wage the estimates of the bargaining power coefficients for blue as well as white collar workers reject the symmetric split the difference outcome determinants of the cross industry variation of bargaining power are explored as well

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

zeros and lumps in investment empirical evidence on irreversibilities and nonconvexities the objective of this paper is to investigate if and how capital adjustment departs from the smooth pattern implied by standard model based on convex adjustment costs using norwegian micro data we start by documenting the intermittent and lumpy nature of investment rates we then present two pieces of econometric evidence on these issues first we estimate a discrete hazard model to determine the probability of having an episode of high investment conditional on the length of the interval from the last high investment episode second we estimate a switching regression model that allows for the response of the investment rate to fundamentals to differ across regimes in both cases we investigate the aggregate implications of our results

price adjustment costs and the output inflation trade off when prices are costly to adjust there is a trade off between the rate of inflation and the firm s average level of output this trade off is the result of fully optimizing behaviour by the firm sufficient conditions are developed for inflation to have no effect on output however these conditions are unlikely to be met in practice this suggests that the superneutrality of money hypothesis is incompatible with the type of demand and cost curves normally encountered in economic theory if the discount rate is positive moderate rates of inflation will always lead to higher levels of output

a dynamic economy with costly price adjustments this paper studies a general equilibrium model of a dynamic economy with menu costs each firm s productivity is exposed to idiosyncratic and aggregate productivity shocks around a trend and the money supply to monetary shocks around a trend all consumption pricing and production decisions are based on optimizing behavior there exists a staggered markov perfect equilibrium with prices determined by a two sided s s markup strategy the paper analyzes the optimal markup strategy and investigates the dynamics of the price index and the aggregate output the welfare consequences of the uncertain aggregate productivity and money supply are also examined

machine replacement and the business cycle lumps and bumps this paper explores investment fluctuations due to discrete changes in a plant s capital stock the resulting aggregate investment dynamics are surprisingly rich reflecting the interaction between a replacement cycle the cross sectional distribution of the age of the capital stock and an aggregate shock using plant level data lumpy investment is procyclical and more likely for older capital further the predicted path of aggregate investment that neglects vintage effects tracks actual aggregate investment reasonably well however ignoring fluctuations in the cross sectional distribution of investment vintages can yield predictable nontrivial errors in forecasting changes in aggregate investment

search price setting and inflation a model of monopolistic competition in an inflationary environment is developed which embodies optimal sequential search price dynamics and entry on the part of consumers and firms respectively equilibrium price strategies are s s these bounds increase continuously with consumer search costs and so does price dispersion indeed the whole equilibrium varies smoothly from the competitive bertrand to the monopolistic diamond 1971 end of the spectrum the latter s paradoxical result is explained as a limiting case where frictions on firms side of the market price adjustment costs but not on buyers search costs tend to zero a positive relationship between smooth and perfectly anticipated inflation and price dispersion or uncertainty is established

what has luck got to do with it a regional analysis of poverty and agricultural growth in rural india this article explores the role of agro ecological factors associated with agricultural growth and poverty outcomes in india using a new operationalisation of agro ecological factors and incorporating within state variations in poverty and other variables we show that agricultural growth and poverty reduction appear to depend on underlying agro ecological conditions which are favourable to the spread of irrigation and hence agricultural development which in turn in associated with poverty reduction promotion of agriculture in less favoured areas in unlikely to have similar effects on agriculture in less favoured areas is unlikely to have similar effects on agricultural growth even if the effects of agricultural growth on poverty remain similar unless conditions for irrigation are favourable or rainfall is sufficiently abundant and reliable this suggests that considerable caution may be needed in drawing policy conclusions from empirical analysis by state alone and without regard to their underlying f

aggregate employment dynamics building from microeconomic evidence this paper studies quarterly employment flows of approximately 10 000 u s manufacturing establishments the authors use establishments hours week to construct measures of the deviation between desired and actual employment and use these as the establishments main state variables the main findings are 1 microeconomic adjustment functions are nonlinear with plants adjusting disproportionately to large shortages 2 adjustments are often either large or nil suggesting the presence of nonconvexities in the adjustment cost technologies 3 the bulk of average employment fluctuations is accounted for by aggregate rather than reallocation shocks and 4 microeconomic nonlinearities amplify the impact of large aggregate shocks copyright 1997 by american economic association

trade liberalisation poverty and inequality in vietnam a quantile regression approach abstractthis study examines the effects of trade liberalisation on rural household welfare poverty and inequality in vietnam with the use of multiple estimation strategies including the panel quantile regression approach based on canay s two step estimator taking account of the multi faceted nature of trade liberalisation we consider a set of household level trade related variables including employment in export import competing and manufacturing sectors a unique panel data set is constructed from the vietnam household living standards surveys conducted in 2002 2004 and 2006 we find that employment in trade related sectors contributes significantly to rural household welfare moreover the effects of trade related employment on welfare are heterogeneous across the welfare income distribution in that trade related employment sectors have different influences on different groups quantiles of households

the comovement between output and prices abstract in this paper i analyze the comovement of us prices and output in the postwar period i use a new set of statistics to characterize the comovement between variables the statistics capture important information about the dynamics in the system the estimation procedure does not require assumptions about the order of integration or the types of assumptions needed for var decompositions i find that the comovement between output and prices is positive in the short run and negative in the long run i show that a model in which demand shocks dominate in the short run and supply shocks dominate in the long run can explain these empirical results while sticky price models with only demand shocks cannot

bertrand edgeworth equilibria when firms avoid turning customers away this paper provides a simple solution to the problem of nonexistence of pure strategy equilibria in bertrand edgeworth models with strictly convex costs the voluntary trading constraint in standard bertrand edgeworth models is generalized to allow for there being costs incurred when customers are turned away so long as the industry is sufficiently large the presence of such costs ensures that the competitive price will be an equilibrium there will be other single price equilibria but if the offense costs are small all equilibria will be close to the competitive outcome

the impact of agricultural research on productivity and poverty in sub saharan africa while it is widely recognized that agricultural research is a key driver of broad based technological change in agriculture that benefits the poor in many different ways little is known about its aggregate impacts on productivity growth and poverty reduction in sub saharan africa ssa using a polynomial distributed lag structure for agricultural research within a simultaneous system of equations framework this paper first demonstrates that agricultural research contributes significantly to productivity growth in ssa productivity growth is again shown to raise per capita incomes with income increases finally having significant poverty reducing effects with an aggregate rate of return of 55 the payoffs to agricultural research are also impressive agricultural research currently reduces the number of poor by 2 3 million or 0 8 annually while the actual impacts are not large enough to more than offset the poverty increasing effects of population growth and environmental degradation the potential impacts of agricultural research are far greater apart from low research investments ssa faces several constraints outside the research system that hinder realization of potential research benefits the results show that doubling research investments in ssa would reduce poverty by 9 annually however this would not be realized without more efficient extension credit and input supply systems

trade openness and economic growth a cross country empirical investigation abstract this paper demonstrates that trade liberalization does not have a simple and straightforward relationship with growth using a large number of openness measures for a cross section of countries over the last three decades we use two groups of trade openness measures the regression results for numerous trade intensity ratios are mostly consistent with the existing literature however contrary to the conventional view on the growth effects of trade barriers our estimation results show that trade barriers are positively and in most specifications significantly associated with growth especially for developing countries and they are consistent with the findings of theoretical growth and development literature

colluding on excluding abstract in an oligopoly characterized by barriers to re entry a finite horizon complete information convex costs and the presence of three identical firms i show that in subgame perfect equilibrium two of them the predators can choose to charge an initial price that is so low that the third the prey decides to exit immediately in this predatory pricing equilibrium the predators can enjoy higher profits than in the best collusive equilibrium with three firms thus a coalition of two firms can benefit from colluding on excluding

on inflation and output with costly price changes a simple unifying result we analyze the effect of inflation on the average output of monopolistic firms facing a small fixed cost of changing nominal prices using taylor expansions we derive a general closed form solution for the slope of the long run phillips curve this very simple unifying formula allows us to evaluate and clarify the role of three key factors the asymmetry of the profit function the convexity of the demand function and the discount rate these partial equilibrium effects remain important components of any general equilibrium model with s s pricing this abstract was borrowed from another version of this item

tariff rates tariff revenue and tariff reform some new facts this article compares the statutory and valorem tariff rates official rates with the ratio of tariff revenues to import values collected rates for jamaica kenya and pakistan it identifies four general features of the tariff codes considers whether these features apply to all developing countries and discusses four implications of these features for tariff reform first the collected rate for any given item in the tariff code is only weakly related to the official rate for the item second the variation of collected rates on average increase much less than the official rates fourth the relation between official rates and collected rates is nonlinear because the slope is lower at higher levels of the official rate

price points and price rigidity abstract we study the link between price points and price rigidity using two data sets weekly scanner data and internet data we find that 9 is the most frequent ending for the penny dime dollar and ten dollar digits the most common price changes are those that keep the price endings at 9 9 ending prices are less likely to change than non 9 ending prices and the average size of price change is larger for 9 ending than non 9 ending prices we conclude that 9 ending contributes to price rigidity from penny to dollar digits and across a wide range of product categories retail formats and retailers

households vulnerability from trade in vietnam abstract this paper assesses vulnerability from trade in vietnam by presenting an extended version of ligon and schechter s 2003 vulnerability as low expected utility veu measure it uses the vietnam household living standard surveys vhlss panel data covering the period 2002 06 the empirical results show that risk induced vulnerability and heterogeneity in trade exposure matter in determining household overall vulnerability and that this is not linked to the actual manifestation of shocks although it does not represent by any means an argument against free trade this work is relevant for policymaking since it contributes to deepen our knowledge on the subtle links between trade openness and vulnerability and informs us about suitable instruments to accompany it

trade liberalisation and poverty reduction in vietnam this paper investigates the impacts of trade liberalisation on poverty reduction in vietnam during the period of economic reform using a combined approach dealing with four transmitting channels from trade to poverty the major findings are summarised as follows first vietnam s trade liberalisation has fostered economic growth which has helped to raise per capita gdp and reduce poverty second trade liberalisation has directly benefited the poor through creating pro poor employment and raising wages third another impact of trade liberalisation on poverty is income and substitution effects associated with reduced domestic prices of importables and increased domestic prices of exportables such as coffee and rice fourth trade liberalisation has indirectly benefited the poor because it raises government revenue which enhances the government s ability to subsidise the poor finally although the poverty rate in vietnam has been reduced impressively there is an increasing disparity between urban and rural areas and among the latter concern does exist regarding ethnic minorities

inflation output and labour productivity when prices are changed infrequently when prices are changed infrequently the effect of inflation on output depends on the form of profit and demand functions this paper provides a general taxonomy at small inflation rates output falls rises stays the same if the demand function is concave convex linear in terms of the log of real price this holds when the frequency of price changes is fixed in case of a catalogue firm as well as when it is chosen optimally in case of a menu cost firm with fixed and variable price adjustments costs with some specifications inflation increases output but reduces labor productivity copyright 1990 by the london school of economics and political science

the impacts of information on returns from farming evidence from a nationally representative farm survey in india using a nationally representative sample of farm households from india this paper examines the impact of use of information on net farm incomes employing methodologies that mitigate potential biases in the estimation of the impact the empirical results show that farmers who use information realize over 12 higher net returns per hectare the paper also establishes a pecking order in access to information small farmers and those at the bottom of social hierarchy based on caste have access to fewer information sources and they depend more on informal social networks and input dealers for their information needs the larger farmers and those from upper caste rely relatively more on sources such as radio television and newspaper

bertrand edgeworth equilibrium with a large number of firms abstract we examine a model of price competition with strictly convex costs where the firms simultaneously decide on both price and quantity are free to supply less than the quantity demanded and there is discrete pricing if firms are symmetric then for a large class of residual demand functions there is a unique equilibrium in pure strategies whenever for a fixed grid size the number of firms is sufficiently large moreover this equilibrium price is within a grid unit of the competitive price the results go through to a large extent when the firms are asymmetric or they are symmetric but play a two stage game and the tie breaking rule is weakly manipulable

integrity for hire an analysis of a widespread customs reform abstract can governments improve bureaucratic performance by hiring integrity from the private sector in the past 2 decades a number of developing countries have hired private firms to conduct preshipment inspections of imports generating independent data on the value and tariff classification of incoming shipments i find that countries implementing such inspection programs subsequently experience large increases in import duty collections by contrast the growth rate of other tax revenues does not change appreciably additional evidence suggests that declines in falsification of import documentation are behind the import duty improvements the programs also lead to declines in undervaluation and misreporting of goods classifications historically this hired integrity appears to have been cost effective with improvements in import duty collections in the first 5 years of a typical inspection program amounting to 2 6 times the program s costs

comparing cournot and bertrand in a homogeneous product market abstract this paper examines some general notions relating to the comparison of cournot and bertrand equilibrium outcomes results obtained by vives in this connection are reconsidered in a homogeneous product market and it is shown that these results are sensitive to the market sharing rules it is found that the results are always true under those market sharing rules which have the property of including the competitive equilibrium in the set of bertrand equilibria for example the capacity sharing rule if however the sharing rule does not have this property for example the equal sharing rule then the results referred to above may not hold when costs are asymmetric journal of economic literatureclassification numbers l13

land rights gender equality and household food security exploring the conceptual links in the case of india this paper seeks to critically examine the conceptual linkages between the issue of land rights for women with household food security on the one hand and gender equality on the other after a brief analysis of shifts in both international and national policy discourse and practice in terms of control over land as vital for food security it seeks to analyse the implications of this for gender relations the paper argues that in a context of diversified rural livelihoods the contribution of agricultural production to household subsistence has been declining this trend has been reinforced by a decline in public investment stagnant growth and fluctuating prices for agricultural products men have been able to access the better paid non farm jobs while leaving women behind to manage agricultural production the renewed link between production and food security in agricultural policy has however meant allowing men not to have responsibility for household food security while a right to land for women is a positive development it appears also to be leading to an enhancement of work burdens without much change in terms of status or decision making authority
