to float or to fix evidence on the impact of exchange rate regimes on growth we study the relationship between exchange rate regimes and economic growth for a sample of 183 countries over the post bretton woods period using a new de facto classification of regimes based on the actual behavior of the relevant macroeconomic variables in contrast with previous studies we find that for developing countries less flexible exchange rate regimes are associated with slower growth as well as with greater output volatility for industrial countries regimes do not appear to have any significant impact on growth the results are robust to endogeneity corrections and a number of alternative specifications borrowed from the growth literature

observable and unobservable determinants of replacement of home appliances despite the dominant role of replacement purchases in many consumer durable categories the research in this area has not been extensive only in the last few years has the economic theory made progress towards a more rigorous analysis of the dynamic nature involved in replacement decisions as a consequence of this applied researchers have switched from conventional discrete choice models to new econometric techniques e g duration analysis that allow for richer relationships between socioeconomic variables characteristics of the durable good and the likelihood of its replacement over time our study focuses on two home appliances taken from the residential energy consumption survey recs based on a duration model that allows for unobserved heterogeneity across households we conclude that household demographics and product features both observable and unobservable in general have statistical power to explain replacement decisions over time

currency unions in africa is the trade effect substantial enough to justify their formation using estimates that currency unions double trade we quantify the welfare effects of forming currency unions for the african regional economic communities and for the african union as a whole the potential increase in trade is shown to be small and much less than that resulting from the adoption of the euro allowing for increased african trade does not overturn the negative assessment of african currency unions due to asymmetries in countries terms of trade shocks and their degree of fiscal discipline

exchange rate policy for developing countries according to the imf in the mid 1970 s approximately 85 percent of developing countries had pegged exchange rate arrangements since then the situation has changed drastically today most developing countries have either managed floats or flexible exchange rates argentina hong kong and a few others may persevere with their currency boards additional nations may well imitate them and movements toward common currencies a la the european union may gain strength here and there nonetheless it seems clear that the political and financial prerequisites to adopt such hard pegs are extremely stringent new attempts are the exception not the rule the question for most emerging market economies is no longer to float or not to float but how to float in this note we review some key issues in defining the right answer to this question

a normative model of behavior based upon an activity hierarchy this paper integrates the psychological framework of a preference hierarchy with the economic framework used to analyze the allocation of time and commodities residual income available to an activity is found to be the primary determinant of the level of an activity s time and commodity demands and the most important variable affecting marginal consumption of new commodities

a faith based initiative meets the evidence does a flexible exchange rate regime really facilitate current account adjustment it is often asserted that a flexible exchange rate regime would facilitate current account adjustment using data on over 170 countries over the 1971 2005 period we examine this assertion systematically we find no strong robust or monotonic relationship between exchange rate regime flexibility and the rate of current account reversion even after accounting for the degree of economic development and trade and capital account openness this finding presents a challenge to the friedman 1953 hypothesis and a popular policy recommendation by international financial institutions

price dispersion and seller heterogeneity in retail food markets price dispersion i e a homogeneous product being sold at different prices by different sellers is among the most replicated findings in empirical economics the paper assesses the extent and determinants of spatial price dispersion for 14 perfectly homogeneous food products in more than 400 retailers in a market characterized by the persistence of a large number of relatively small traditional food stores alongside large supermarkets the extent of observed price dispersion is quite high when prices in an urban area where the spatial concentration of sellers is higher are compared with those in smaller towns and rural areas differences in search costs and the potentially higher degree of competition do not yield lower prices other counteracting factors including differences in seller costs and consumer incomes make prices on average higher in the urban area for 11 of the 14 products considered for many but not all the products supermarkets proved to be less expensive than traditional retailers although average savings from food shopping at supermarkets were extremely low finally the results of the study provide evidence that retailers have different pricing strategies and these differences also emerge for supermarkets belonging to the same chain the results presented in the paper suggest that a variety of factors play a role in explaining price dispersion in addition to differences in seller costs the contemporaneous heterogeneity of retailers in terms of services provided and consumers in terms of search costs and preferences makes the emergence of monopolistic competition possible as well as allowing small traditional food retailers to remain in business

grouping durable goods modelling consumer preferences has a long history of interest in the literature several approaches that have been proposed consider consumer behaviour to be hierarchical products are divided into groups and preferences within a group are modelled independently an important question that arises in these efforts concerns the development of appropriate higher level groups this paper replicates and extends an earlier study by pickering et al 1973 in which product groups were developed based on consumer perceptions of product attributes we collect survey data perceived product attributes and similarity ratings for a set of durable products multiple measures are thus used to test the stability and consistency of product groups a matrix of product similarity values is constructed for each of these two survey based measures cluster analysis is then performed to develop a grouping scheme for these durable goods althought differences are observed the product composition of the resulting product groups a

german dominance in the ems evidence from interest rates abstract the paper presents an empirical analysis of german dominance and asymmetries in the ems based on a dynamic system of equations explaining national money market interest rates the hypothesis of strict german dominance of the ems is rejected however there are some noticeable asymmetries in the ems germany is a relatively strong player and has been the least dependent country in the early phase of the system since 1983 german independence has diminished in contrast france throughout and italy in the early phase of the ems have been relatively weak players in the system

exchange rate regimes and fdi in developing countries a propensity score matching approach abstract theory suggests that regimes of relatively fixed exchange rates encourage inward foreign direct investment fdi relative to regimes of more flexible exchange rates we use propensity score matching psm to investigate the relationship between the exchange rate regimes of 70 developing countries and fdi into such countries using de facto regime classifications we include a large number of variables in the logit equation that estimates the propensity score the probability of regime choice we also use general to specific modeling to get alternative parsimonious versions based on four matching procedures the average treatment effects suggest with overall modest statistical significance that relatively fixed de facto regimes do encourage fdi compared with relatively floating regimes in addition the estimated effects are sometimes economically large

modelling the consumer s decision to replace durable goods a hazard function approach this article analysis the consumer s durable good replacement decision using hazard models in contrast to the typical limited dependent variable model often used in durable good demand studies hazard models allow for much richer replacement to illustrate the technique a recursive system consisting of a regression equation and a hazard model is used to examine home heating system replacement decisions by residencial customers of a major southeasten us electric utility the results indicate that overall system replacement rates decline over time and that the probability of replacement for specific households depends negatively on the age of the head of household abd the availability of natural gas and positively on system age and higher than expected household energy use

exchange rate behaviour under the ems regime was there any systematic change abstract most empirical studies fail to detect any systematic effects of the ems regime on the economic performance of member countries this reveals the difficulty of constructing controlled experiments which can distinguish what is due to the ems from that due to common external pressures we argue that the crucial step is to examine the exchange rates distribution since no performance improvements will appear if exchange rate behaviour does not change within the ems we find that there are changes in the third and fourth moments which imply that ems currencies have become more fragile and susceptible to shocks particularly negative shocks relative to non ems currencies

patterns of retail price variation we examine retail price variation across a range of goods and regions of the united states we find that the typical grocery product has a regular price and stays at that price at least 50 of the time and that most deviations from that regular price are downward temporary discounts or sales while infrequent account for 20 to 50 of the annual variation in retail prices for most product categories although existing models of retail sales yield predictions consistent with some aspects of the retail pricing distributions all of these models fail to explain other important aspects of retail pricing identified here

current account balance and dollar standard exploring the linkages abstract this paper examines whether the international role of the dollar as main global reserve currency has contributed to persistent current account imbalances to this end we analyse how central banks accumulation of reserve assets affects the current account balance of both reserve accumulating and reserve providing countries based on a simple portfolio balance model we show theoretically that the global demand for reserve assets by central banks may lower the current account balance of the reserve issuing country our panel data analysis over the period 1970 2009 confirms this hypothesis any dollar of provided reserve assets decreases the us current account by more than one dollar on average the demand for dollar reserves has lowered the us current account by 1 2 percentage points relative to gdp the flip side of this effect is a higher current account balance in reserve accumulating countries these novel findings show that the worldwide demand for international reserves has contributed to the buildup of global imbalances

general to specific modelling using pcgets this review examines the facilities provided by pcgets version 1 0 an oxmetrics module designed to implement automated general to specific model selection in the context of cross section or dynamic time series models that are linear in the parameters a cross section empirical example is used to illustrate the steps involved the output produced and the options available for modellers copyright blackwell publishing ltd 2003

time consistent collection of optimal seigniorage a unifying framework this paper reviews the existing literature on the time consistency problem of seigniorage collection when monetary policy is determined by optimal taxation considerations it develops a unifying accounting framework and suggests a general measure for seigniorage which encompasses the standard measures employed in the literature in addition the ex ante optimal solution to the optimal taxation problem is derived and interpreted in relation to the ramsey principle we show that the different recommendations of the public finance literature i e the friedman rule of optimal deflation moderately positive inflation and seigniorage maximizing inflation are specific solutions to the optimal taxation problem the paper continues with a formal illustration of the time consistency problem of the ex ante optimal policy and the characterization of the time consistent solution under discretion as possible solutions to the time consistency problem we consider reputational forces institutional reforms that establish central bank independence and specific ways of asset and debt management in particular it is formally shown that a modified version of the asset and debt management scheme suggested by persson persson and svensson is not only necessary but also sufficient for optimality although this did not hold in their model

current accounts and oil price fluctuations in oil exporting countries the role of financial development abstract oil exporting countries usually experience large current account improvements following a sharp increase in oil prices in this paper we investigate this oil price current account relationship on a sample of 27 oil exporting economies relying upon the estimation of panel smooth transition regression models over the 1980 2010 period we provide evidence that refines the traditional interpretation of oil price effects on current accounts while current accounts are positively affected by oil price variations this effect is nonlinear and depends critically on the degree of financial development of oil exporting economies more specifically oil price variations exert a stronger impact on the current account position for less financially developed countries this influence diminishing with financial deepness

capital controls and balance of payments crises abstract the theory of balance of payments crises shows that under perfect foresight a system of fixed exchange rate is not sustainable in the presence of diverging economic policies in this paper it is shown how and why capital controls succeed in maintaining the principle of a fixed but adjustable parity both cases of a devaluation and a revaluation are considered and a condition for a parity change to be credible is presented

delegation in international monetary policy games abstract in this paper we show that delegation of monetary policy to an independent and more conservative central banker is an optimal policy in a multi country framework with monetary spillovers among countries even in the absence of time inconsistency credibility issues we also study the welfare implications of delegating monetary policy and extend our analysis to the case of coordination of monetary policies

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed

rough and lonely road to prosperity a reexamination of the sources of growth in africa using bayesian model averaging this paper takes a fresh look at africa s growth experience by using the bayesian model averaging bma methodology bma enables us to consider a large number of potential explanatory variables and sort out which of these variable can effectively explain africa s growth experience posterior coefficient estimates reveal that key engines of growth in africa are substantially different from those in the rest of the world more precisely it is shown that mining primary exports and initial primary education exerted differential effect on african growth these results are examined in relation to the existing literature copyright 2008 john wiley sons ltd

retail price dynamics and retailer heterogeneity uk evidence we examine retailer heterogeneity in price adjustment in uk supermarkets considerable variation in the price change frequency of identically bar coded products among retail chains is found decomposition analysis suggests that price adjustment is evenly split between sales and reference prices with substantive variation across retailers

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

credibility and disinflation in the european monetary system analysis of interest differentials in the european monetary system has suggested a widespread lack of credibility of the exchange rate mechanism in the sense that in most countries the implicit expected rate of devaluation was significant and not far short of inflation differentials vis a vis the deutschmark we present and test a model in which prices reflect expectations of exchange rate behaviour the results provide mixed evidence that price setting in countries which participated in the erm was influenced by the exchange rate discipline

political business cycles and macroeconomic credibility a survey there is clear evidence that government popularity and election performance is affected in part by economic performance suggesting that governments may manipulate the economy to political advantage simple models incorporating adaptive expectations which allowed the government to exploit this relationship were developed in the 1970s but fell out of fashion with the advent of new classical economics however modern theories of the political business cycle which are closely related to the macroeconomic policy game literature assume rational expectations and lead to forms of political business cycle driven by the existence of uncertainty of one type or another the international evidence suggests that some aspects of the theories apply although definitive conclusions are as we might expect hard to come by

classifying exchange rate regimes deeds vs words abstract most of the empirical literature on exchange rate regimes uses the imf de jure classification based on the regime announced by the governments despite the recognized inconsistencies between reported and actual policies in many cases to address this problem we construct a de facto classification based on data on exchange rates and international reserves from all imf reporting countries over the period 1974 2000 which we believe provides a meaningful alternative for future empirical work on the topic the classification sheds new light on several stylized facts previously reported in the literature in particular we find that the de facto pegs have remained stable throughout the last decade although an increasing number of them shy away from an explicit commitment to a fixed regime hidden pegs we confirm the hollowing out hypothesis but show that it does not apply to countries with limited access to capital markets we also find that pure floats are associated with only relatively minor nominal exchange rate volatility and that the recent increase in the number of de jure floats goes hand in hand with an increase in the number of de facto dirty floats fear of floating

exchange rate regimes and current account adjustment an empirical investigation the acceleration in the formation of global imbalances in the period preceding the last financial crisis prompted a revival of the debate on whether exchange rate regimes affect the flexibility of the current account i e its degree of mean reversion as originally proposed by friedman 1953 i analyse this relation systematically using a panel of 180 countries over the 1960 2007 period i find robust evidence that flexible exchange rate arrangements deliver a faster current account adjustment among non industrial countries additionally i try to identify channels through which this effect could be taking place the results suggest that exports respond to expenditure switching behaviour by consumers when faced with changes in international relative prices configuring a potential channel

delegation in a general equilibrium model of customs unions abstract a difference in the objectives of members of a customs union may be a unifying rather than a divisive force if countries outside the union behave strategically one union member may want to delegate to its partner the ability to set the common external tariff we demonstrate these results in the context of a pure exchange general equilibrium trade model we show that if tariffs are strategic substitutes the union country which is relatively less well endowed in the exported good may be willing to delegate to its partner which behaves more aggressively in setting the union s policy the delegation decision is reversed if tariffs are strategic complements the model extends the standard results on the appropriate level of the union policy by adding another dimension that of the optimal decision making agent

the effectiveness of monetary policy anchors firm level evidence analyses of monetary policy posit that exchange rate pegs inflation targets and central bank independence can help anchor private sector inflation expec tations yet there are few direct tests of this argument we offer cross national micro level evidence on the effectiveness of monetary anchors in controlling private sector inflation concerns using firm level data from eighty one countries approximately 10 000 firms we find evidence that international anchors exchange rate commit ments correlate significantly with a substantial reduction in private sector concerns about inflation while domestic anchors inflation targeting and central bank inde pendence do not our conjecture is that private sector inflation expectations are more responsive to exchange rate anchors because they are more transparent more con straining and more costly than domestic anchoring arrangements the literature on monetary policy highlights the role of monetary institutions in stabilizing private sector inflation expectations central bank independence cbi inflation targeting it and fixed exchange rates pegs are widely viewed as insti tutions that have the capacity to mitigate private sector concerns that policymak ers will exploit them after they have locked in their price wage and investment decisions while other empirical research explores the institutional correlates of inflation and its variability yielding mixed results we use firm level data in our study to directly assess the impact of monetary anchors on private sector inflation concerns we find evidence that pegs mitigate firm owners concerns with infla tion but that domestic anchors such as it and cbi are uncorrelated with our micro indicators of inflation expectations considerable research has investigated the use of it cbi and pegs as institu tions that establish monetary policy credibility whereas these anchors are expected

exchange rate regimes in developing and emerging economies and the incidence of imf programs summary the global economic crisis will compel many countries to revise key economic policies including their exchange rate regime the international monetary fund will have significant influence on their choices and has exhibited a bias against intermediate regimes we examine the link between exchange rate regimes and imf program use and find no evidence that countries with intermediate exchange rate regimes require more frequent imf assistance rather they appear somewhat less dependent especially when compared to fixed exchange rates our results suggest that intermediate regimes should remain a viable and possibly desirable exchange rate choice for some countries

hard or soft pegs choice of exchange rate regime and trade in africa summary this paper revisits the link between fixed exchange rate regimes and trade in the context of africa s exchange rate arrangements differentiating the effects of hard pegs currency unions from conventional soft pegs using a novel dataset of exchange rate regime classification the paper augments the gravity model of bilateral trade flows with measures of currency unions and conventional pegged arrangements and benchmarks africa s experience against the rest of the world we find that in both samples currency unions and pegs increase trade vis a vis more flexible exchange rate arrangements through channels in addition to reduced exchange rate volatility however the effect is almost twice as large for africa in addition the trade generating effect of pegs is at least as large for africa as that of currency unions suggesting that pegs could present a viable option perhaps an alternative to currency unions to promote trade in the region

sales and monetary policy this paper analyses the efiect of monetary policy in a model where sales occur in equilibrium some consumers are loyal to a particular brand of a good others are bargain hunters as a result producers flnd it optimal to sell their goods at a normal price through some retailers and at a sale price through others the margin of adjusting the amount sold on sale is potentially very important if producers can adjust the fraction sold on sale with sticky prices and wages money is approximately neutral if we ignore the reasons behind sales but that result changes dramatically when we consider that producers optimally choose to sell some of their goods on sale owing to strategic substitutabilities in the sales decision money has strong procyclical efiects

credibility and exchange rate management in developing countries abstract the paper discusses the role of credibility factors in the conduct of exchange rate policy in developing countries the analysis is based on a simple framework in which policymakers are concerned about inflation and external competitiveness price setters in the nontradable sector of the economy engage in a strategic game against the authorities the model generates a devaluation bias which undermines the credibility of a fixed exchange rate the role of reputational factors signaling considerations and joining a currency union as possible solutions to this bias is examined

workers remittances and the real exchange rate a paradox of gifts abstract we test the impact of workers remittances on the real exchange rate using a panel of 13 latin american and caribbean countries the analysis reveals that workers remittances have the potential to inflict economic costs on the export sector of receiving countries by reducing its international competitiveness our findings raise concerns parallel to those raised by dutch disease or resource boom models where resource discoveries result in real exchange rate appreciation and shifting of resources from the traded to the nontraded sectors of the economy

seigniorage and the case for national money in countries with high rates of inflation there is typically movement away from the use of the local currency the paper analyzes the costs and benefits of using a local currency with emphasis on the seigniorage foregone by using a foreign money even if it should be desirable for a country to fix its exchange rate it still loses seigniorage if it does not use its own money the case for using a foreign money then turns largely on the superior discipline imposed on domestic policymakers by removing their control over the money supply alternative methods of imposing discipline are discussed estimates of the amount of seigniorage raised by different governments are presented seigniorage amounts in some cases to about 10 percent of government revenue estimates are also presented of both the annual flow and one time stock costs of giving up use of domestic currencies and instead using the dollar the flow cost is typically about 1 percent of gnp and the stock cost is around 10 percent of gnp

preference trees preference hierarchies and consumer behavior n a recent article coursey 1985 i considered consumer behavior in a model in which preferences are described by an activity hierarchy using this activity hierarchy description consumers were found to sequentially satisfy higher ranked activities in their preference ordering up to the point that their monetary and time resources were exhausted among the more interesting implications of this behavior were that 1 if a consumer s economic resources are subsequently increased then additional consumption will commence at the point where the consumer s resources were initially exhausted 2 a change in the price of a commodity used in an activity will have a pure substitution effect in the production of that activity and a spillover income effect at the point of resource exhaustion and 3 comparative statics effects of any change are unidirectional and will affect behavior only from the point where the effects enter the consumer s sphere forward to the point of exhaustion of economic resources the results were derived under the assumption that each commodity can be used in the production of only one activity in their follow up article brooks and earl 1987 relaxed this assumption and considered the implications of jointness in consumption in the context of the activity hierarchy model in their extension a commodity may be used as a perfect substitute at different places in the activity hierarchy they concluded that my general results become less clear when commodities can be used in this fashion i fully concur with their motive for this extension and welcome their remarks as a further contribution to the field of choice regarding priorities 2 in this brief article i wish to outline fully how their results should be interpreted one interpretation involves the theoretical relationship between the activity hierarchy model and the more traditional to economists utility maximization model the second interpretation involves the use of the activity hierarchy model and its extensions for empirical analysis

hierarchical choice in economics abstract the paper examines the relevance for economic issues of choice which is not characterized by unlimited substitutability after showing that hierarchical choice is common in other social sciences like psychology the paper proceeds with an examination of such choice and of its different categories subsequently the implications for hierarchical choice for specific economic issues are analysed in particular there is discussion and literature review of demand theory engel curves the theory of the firm and social choice theory finally some suggestions for the application to other economic problems are considered

modelling profitability using survival combination scores abstract the paper presents the first empirical investigation of the relationship between present value of net revenue from a revolving credit account and times to default and to second purchase the analysis is based on the data for a store card which is used to buy white durable goods in germany it is demonstrated that there exists a relationship between the above given measures it appears that there is a scope for improving profit if an application for a store card is assessed by using a model which estimates the revenue and includes the survival probability of default and the survival probability of second purchase a survival combination model rather than merely a static probability of default predicted by a logistic regression

pass through in retail and wholesale this paper studies how prices comove across products firms and locations to gauge the relative importance of retailer versus manufacturer level shocks in determining prices i make use of a large panel data set on prices for a cross section of retailers in the u s i analyze prices at the barcode or universal product code upc level for individual stores i find that only 16 of the variation in prices is common across stores selling an identical product 65 of the price variation is common to stores within a particular retail chain but not across retail chains while 17 is completely idiosyncratic to the store and product product categories with frequent temporary sales exhibit a disproportionate amount of completely idiosyncratic price variation my results suggest that most of the observed price variation arises from retail level rather than manufacturer level demand and supply shocks however the behavior of prices is difficult to relate to observed variation in costs and demand at the retail level this suggests that retail prices may vary largely as a consequence of dynamic pricing strategies on the part of retailers or manufacturers rather than static demand and supply shocks this abstract was borrowed from another version of this item

financial development and economic growth evidence from panel unit root and cointegration tests abstract in this paper we investigate the long run relationship between financial depth and economic growth trying to utilize the data in the most efficient manner via panel unit root tests and panel cointegration analysis in addition we use threshold cointegration tests and dynamic panel data estimation for a panel based vector error correction model the long run relationship is estimated using fully modified ols for 10 developing countries the empirical results provide clear support for the hypothesis that there is a single equilibrium relation between financial depth growth and ancillary variables and that the only cointegrating relation implies unidirectional causality from financial depth to growth

the importance of the exchange rate regime in limiting current account imbalances in sub saharan african countries abstract one of the major current concerns of economic policy in developing countries is the choice of the appropriate exchange rate regime to consolidate and accelerate the pace of economic growth this paper aims to investigate whether the choice of a country s exchange rate regime may affect current account imbalances for sub saharan african economies to this end we first use bayesian model averaging bma supplemented by the general to specific gets method to address concerns about model uncertainty and identify the key determinants fundamentals of external balances then estimating current account imbalances over the period 1980 2012 we show that flexible exchange rate regimes are more effective in preventing such disequilibria consequently candidates for membership of monetary unions should discuss widely the possible adjustment mechanisms before forming such unions one potential measure is the sharing of external risks at the regional level

loss of monetary discretion in a simple dynamic policy game abstract we analyze a simple policy game featuring monetary credibility problems and argue that loss of monetary discretion is not advantageous two elements form the basis of our analysis firstly we endogenize the source of credibility problems and secondly we consider a dynamic framework where credibility problems are not time invariant by doing this we are able to demonstrate that credibility problems are temporary and in steady state the government has removed these through sound policies a binding policy rule will only serve as an obstacle towards this steady state

the limits of independence and the policy of the ecb it is argued that the european central bank s independence is not as secure as it seems and that as a result it has appreciable institutional incentives to protect and enhance its position it follows that its behaviour should not be understood as being solely determined by the pursuit of price stability one consequence is that certain points on which it has been criticised on the basis that its approach makes for ineffective monetary policy might be better understood as often effective attempts to protect its position another is that making a central bank or any other institution completely independent may be much harder than it seems and failed attempts which come close are not necessarily to be preferred even by the advocates of independence to less ambitious designs

an institutional economic analysis of the decision to do it yourself in housing renovation this paper examines home renovators decision in choosing do it yourself diy or hiring contractors diy may reduce financial pressure but may lead to potential domestic discord and perils of incompetence hiring contractors may alleviate time pressures but may require more financial resource this choice is modelled as analogous to williamson s corporate strategic decision between outsourcing and internalisation in the context of vertical integration and extended via richardson s capabilities based theory with social reputation effect taken into account based on a survey of brisbane home renovators it is found that the richardson s thesis seems stronger than the williamson s when applied to housing renovation and that trust issues in respect of contractors are paramount

inflationary finance under discrepion and rules inflationary finance involves first the tax on cash balances from expected inflation and second a capital levy from unexpected inflation from the standpoint of minimizing distortions these capital levies are attractive ex post to the policymaker in a full equilibrium two conditions hold 1 the monetary authority optimizes subject to people s expectations mechanisms and 2 people form expectations rationally given their knowledge of the policymaker s objectives the outcomes under discretionary policy are contrasted with those generated under rules in a purely discretionary regime the monetary authority can make no meaningful commitments about the future behavior of money and prices under an enforced rule it becomes possible to make some guarantees hence the links between monetary actions and inflationary expectations can be internalized there is a distinction between fully contingent rules and rules of simple form a simple rule allows the internalization of some connections between policy act ion and inflationary expectations but discretion permits some desirable flexibility of monetary growth this abstract was borrowed from another version of this item

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

on the implications of jointness in a normative model of behavior based on an activity hierarchy t he widespread belief that it is often useful to kill two birds with one stone makes it clear that most consumers recognize that there exists considerable scope for using an input gainfully in the production of more than one consumption activity however economic theorists often forget this lay belief as they set up their formal models and consequently they come to inappropriate conclusions this recently occurred in coursey s 1985 normative analysis of consumer behavior in this journal where he models priority based choice over activities this article indicates how the implications of his model may be modified if activities use a common input 2 in contrast to coursey we show that priority based choice does not necessarily imply that 1 an increase in an individual s income will lead to a reduction in the percentage of a consumer s budget spent on inframarginal activities or 2 a change in the price of a commodity producing a marginal activity will only lead to changes in an individual s consumption of marginal and extramarginal commodities put simply it appears that coursey s general results are valid only when one adopts his implicit assumption that there is no jointness in production

the role of policymakers reputation in the ems disinflations abstract it is frequently argued that the ems itself in connection with the high anti inflation reputation of the german bundesbank is responsible for the inflation reduction and convergence which member countries have experienced based on the game theoretical model of backus and driffill 1985 american economic review 75 530 538 an empirical measure of the government s reputation for fighting inflation is derived by using a bayesian learning approach time varying estimates of these counterinflation reputation measures are computed for the original ems member countries and for a control group of major non ems countries the paper finds that only the smaller ems participants have gained anti inflation reputation during the ems period

examining the behaviour of individual uk consumer prices this article examines how uk consumer prices behave using two databases with millions of price observations the microdata that underpin official consumer prices index data and a database of supermarket prices prices do not change continuously but our key finding is the marked heterogeneity in the data that is not consistent with standard microeconomic foundations that typically form the basis of macroeconomic policy models declining hazard functions and the distribution of price changes also argue against representative agent models our results suggest further work is needed to find a model of price setting that genuinely corresponds to how individual uk consumer prices behave

the cyclicality of sales regular and effective prices business cycle and policy implications author s coibion olivier gorodnichenko yuriy hong gee hee abstract we study the cyclical properties of sales regular price changes and average prices paid by consumers effective prices using data on prices and quantities sold for numerous retailers across many us metropolitan areas inflation in the effective prices paid by consumers declines significantly with higher unemployment while little change occurs in the inflation rate of prices posted by retailers this difference reflects the reallocation of household expenditures across retailers a feature of the data which we document and quantify rather than sales we propose a simple model with household store switching and assess its implications for business cycles and policymakers jel d12 e31 e32 l25 l81

is the exchange rate regime really irrelevant for external adjustment we argue that evidence on whether floating exchange rates facilitate external adjustment is contradictory because existing regime classifications do not adequately capture exchange rate flexibility relevant to external adjustment using a trade weighted bilateral exchange rate volatility measure we show that exchange rate flexibility indeed matters for current account dynamics

consumption durables exploring the order of acquisition after an overview of alternative methods for analysing the ownership of consumer durables a particular method is proposed drawn from the principles of social choice theory and ultimately leading to the method of ranking durables equivalent to the borda rule methods are also developed for calculating the uniformity of choice and for identifying differences in patterns of ownership across partitions of the sample

exchange rate regimes and inflation only hard pegs make a difference abstract using data from a large sample of developing countries from 1985 to 2001 we confirm that hard pegs currency boards or a shared currency reduce inflation and money growth there is no evidence that soft pegs confer any monetary discipline after other factors are controlled for inflation triggers regime switches under hard pegs monetary growth is unaffected by fiscal deficits or by inflation shocks under soft pegs as under floats increased fiscal deficits and positive inflation shocks are associated with higher monetary growth the apparently slower per capita output growth under hard pegs is explained by their geographical distribution jel classification f41

the advantage of tying one s hands ems discipline and central bank credibility abstract it is often argued that the ems is an effective disciplinary device for inflation prone countries in europe since it forces the respective policy makers to pursue more restrictive monetary policies than they would otherwise it is not clear however why these countries should submit themselves to such discipline this paper argues that to answer this question appropriately one must consider that ems membership brings potentially large credibility gains policy makers in inflation prone countries the reason is that not only it attaches an extra penalty to inflation in terms of real appreciation but makes the public aware that the policy maker is faced with such penalty and thus helps to overcome the inefficiency stemming from the public s mistrust of the authorities

thousands of models one story current account imbalances in the global economy the global financial crisis has led to a revival of the empirical literature on current account imbalances this paper contributes to that literature by investigating the importance of evaluating model and parameter uncertainty prior to reaching any firm conclusion we explore three alternative econometric strategies examining all models selecting a few and combining them all out of thousands or indeed millions of models a story emerges the chance that current accounts were aligned with fundamentals prior to the financial crisis appears to be minimal

state dependent or time dependent pricing does it matter for recent u s inflation in the 1988 2004 micro data collected by the u s bureau of labor statistics for the cpi price changes are frequent every 4 7 months depending on the treatment of sale prices and large in absolute value on the order of 10 the size and timing of price changes varies considerably for a given item but the size and probability of a price change are unrelated to the time since the last price change movements in aggregate inflation reflect movements in the size of price changes rather than the fraction of items changing price due to offsetting movements in the fraction of price increases and decreases neither leading time dependent models taylor or calvo nor 1 st generation state dependent models match all of these facts some 2 nd generation state dependent models however appear broadly consistent with the empirical patterns

high definition television assessing demand forecasts for a next generation consumer durable high definition television promises to be the next generation of television this technology has broad implications for consumer markets as well as the underlying manufacturing technology development and r d activities of firms under increasing pressure from various groups the u s government must make major policy and funding decisions based on its assessment of the likely demand for hdtv three published reports which forecast sales of hdtv after its scheduled introduction in the mid 1990s are available unfortunately these forecasts offer widely differing perspectives on hdtv s potential this paper presents an approach that links product segmentation based on historical demand parameters and marketing and manufacturing related variables and demand forecasting for new products the published hdtv forecasts are then assessed using this segmentation scheme differing from the congressional budget office s earlier evaluation this analysis indicates that one report is consistent with historical d

transparency reputation and credibility under floating and pegged exchange rates this paper shows that if the cost of importing foreign inflation and real exchange rate shocks are not too high then the equilibrium nominal exchange rate regime for a country with a credibility problem is a peg under which credibility is higher and inflation is lower than under a float this holds true although devaluations of the pegged rate are assumed to be costless the reason is that as realized inflation is not perfectly controllable planned inflation under a float is private information in contrast since the exchange rate can be perfectly controlled pegging resolves the private information problem is more transparent and makes reputation more effective

to be or not to be in monetary union a synthesis article i nfo monetary union can benefit countries suffering from policy credibility problems if it eliminates the inflation bias and also allows for more efficient management of certain shocks but it also carries costs as some stabilization may be feasible even in the absence of credibility and this may be more than what an individual country can hope for in a monetary union in this paper we combine the stabilization and credibility branches of the currency union literature and construct a simple welfare criterion that can be used to evaluate alternative monetary arrangements we produce examples where monetary union may be welfare improving even for low modest levels of inflation bias 2 3 as long as business cycles are not too a synchronized across countries

current account adjustment in developing countries the role of exchange rate regimes i introduction an important question in open economy macroeconomics is whether exchange rate rigidity hinders current account adjustment also known as the friedman hypothesis according to friedman 1953 a flexible exchange rate regime facilitates current account adjustment while a fixed exchange rate regime delays the adjustment process this hypothesis has stimulated extensive research on the relationship between exchange rate regimes and current account reversals e g adalat and eichengreen 2007 de haan schokker and tcherneva 2008 milesi feretti and razin 2000 pancaro and rueffer 2009 while existing studies have made significant contributions to the literature they largely focus on the determinants of current account reversals rather than the duration of current account deficit spells emphasized in the friedman hypothesis does a country s exchange rate regime really matter to how long it stays in a high current account deficit state and if so to what extent does the fixed exchange rate regime delay the adjustment process this article addresses the above important questions by empirically evaluating the role of exchange rate regimes on the duration of high current account deficit spells in developing countries given the prevalence of large and persistent current account deficits across countries over the last few decades understanding the impact of exchange rate regimes on the duration of high deficit spells is particularly important and pertinent specifically we identify high current account deficit spells and employ hazard models to examine whether a fixed exchange rate regime increases the duration of high deficit spells and thus delays current account adjustment 1 a novelty of this approach is that by estimating hazard models we can explicitly test for the effect of exchange rate regimes on the duration of high current account deficit spells which is more in the spirit of the friedman hypothesis on the basis of a large dataset with annual observations for 95 developing countries over the period 1971 2004 we find strong evidence that in developing countries fixed exchange rate regimes are associated with longer duration of high deficit spells and hence significant delays in the adjustment to high current account deficits this finding is robust to alternative exchange rate regime classifications and different model specifications furthermore we show that fixed exchange rate regimes delay current account adjustment only in the hard peg case but not in the soft peg case from a policy perspective this suggests that only the corner solution of a very rigid exchange rate regime delays the current account adjustment but not if the regime allows for some flexibility in the exchange rate adjustment our findings thus lend strong support to the friedman hypothesis the remainder of the article proceeds as follows after a brief review of the relevant literature in section ii section iii provides a description of our dataset and defines high deficit spells in section iv we discuss the methodological issues involved in the duration analysis the empirical results are presented in section v and section vi concludes ii the literature on exchange rate regimes and current account adjustment the discussion on the relationship between exchange rate regimes and current account adjustment goes back to friedman s seminal work in the 1950s friedman 1953 argues that nominal exchange rate flexibility expedites current account adjustment while nominal exchange rate rigidity delays the adjustment under a flexible exchange rate system where the exchange rate is allowed to vary freely a rising current account deficit would induce the depreciation of domestic currency which in turn leads to an increase in exports a decrease in imports and a rapid convergence to a balanced current account in the case of fixed exchange rate regimes where exchange rates are not allowed to vary countries have to rely solely on internal price adjustment mechanisms to produce corrective movements in their current accounts

external adjustment and the global crisis abstract the period preceding the global financial crisis was characterized by a substantial widening of current account imbalances across the world since the onset of the crisis these imbalances have contracted to a significant extent in this paper we analyze the ongoing process of external adjustment in advanced economies and emerging markets we find that countries whose pre crisis current account balances were in excess of what could be explained by standard economic fundamentals have experienced the largest contractions in their external balance we subsequently examine the contributions of real exchange rates domestic demand and domestic output to the adjustment process allowing for differences across exchange rate regimes and find that external adjustment in deficit countries was achieved primarily through demand compression rather than expenditure switching finally we show that changes in other investment flows were the main channel of financial account adjustment with official external assistance and ecb liquidity cushioning the exit of private capital flows for some countries

reference prices costs and nominal rigidities we assess the importance of nominal rigidities using a new weekly scanner dataset we find that nominal rigidities take the form of inertia in reference prices and costst defined as the most common prices and costs within a given quarter reference prices are particularly inertial and have an average duration of roughly one year even though weekly prices change roughly once every two weeks we document the relation between prices and costs and find sharp evidence of state dependence in prices we use a simple model to argue that reference prices and costs are useful statistics for macroeconomic

consumer choice strategies for comparing noncomparable alternatives research on consumer choice has focused on easily comparable alternatives a subset of the choices consumers regularly face this paper outlines the problem and two general strategies for comparing noncomparable alternatives a subset of choices that has been overlooked in the literature experiments are reported that support use of the strategies

improving policy credibility is there a case for african monetary unions abstract this paper analyzes experience with monetary policy in africa focusing on countries that have participated in rule based regional monetary agreements cfa zone east african currency board and rand monetary area we show that african countries have generally lacked the political institutions necessary for governments to commit credibly on an individual basis to financial stability we argue that monetary unions can provide an alternative means of credible commitment to sound macroeconomic policies but only under certain conditions first exit from a union must be made costly by the existence of parallel regional agreements and or links to the financial and technical assistance of industrial countries second governance structures of monetary unions must be designed so as to maximize chances for enforcement of monetary rules and third if a state seeks to break the rules of a union other member governments must actively oppose such attempts

monetary non neutrality in a multisector menu cost model empirical evidence suggests that as much as one third of the u s business cycle is due to nominal shocks we calibrate a multisector menu cost model using new evidence on the cross sectional distribution of the frequency and size of price changes in the u s economy we augment the model to incorporate intermediate inputs we show that the introduction of heterogeneity in the frequency of price change triples the degree of monetary non neutrality generated by the model we furthermore show that the introduction of intermediate inputs raises the degree of monetary non neutrality by another factor of three without adversely affecting the model s ability to match the large average size of price changes a single sector model with a frequency of price change equal to the median rather than the mean generates monetary non neutrality similar to that in our multisector model our multisector model with intermediate inputs generates variation in real output in response to calibrated aggregate nominal shocks that can account for roughly 23 of the u s business cycle

can equilibrium models explain nominal exchange regime non neutrality evidence from the european monetary system abstract in a recent paper alan stockman argues that the finding that real exchange rate variability id higher under flexible nominal exchange rate systems than under fixed nominal exchange rate systems typically interpreted as evidencee of price stickiness is consistent with equilibriu models stockman s theory we argue predicts that the formation of the european monetary system should have had no effect on the real exchange rate variability of its members we test this prediction and interpret our findings as evidence in support of stockman s theory although not as evidence that equilibrium models can account for nominal exchange regime non neutrality jel f31

on the imperfect substitutability of policy regimes exchange rate targetting vs policy coordination abstract exchange rate targetting is always an imperfect substitute for explicit policy coordination but succeeds when economies are either structurally dissimilar with symmetric shocks or structurally symmetric with dissimilar shocks a joint commitment then generates economies of scale in interventions

aid dutch disease and manufacturing growth abstract we examine the effects of aid on the growth of manufacturing using a methodology that exploits the variation within countries and across manufacturing sectors and corrects for possible reverse causality we find that aid inflows have systematic adverse effects on a country s competitiveness as reflected in the lower relative growth rate of exportable industries we provide some evidence suggesting that the channel for these effects is the real exchange rate appreciation caused by aid inflows we conjecture that this may explain in part why it is hard to find robust evidence that foreign aid helps countries grow

fiscal rules and government borrowing costs international evidence we find that the adoption of numerical fiscal rules reduces government borrowing costs in a sample of 101 advanced and developing countries for 1985 2010 we apply a variety of propensity score matching methods to address the self selection problem of policy adoption and find strong evidence that fiscal rules have large and significant treatment effects on lowering government borrowing costs in both international and domestic financial markets the results are robust to changes in country sample and alternative estimation methodology and are consistent with fiscal rules helping to build policy credibility by reducing the probability of default and the risk premium on government debt that compensates lenders for this possibility jel e43 g12 h60

the phillips curve the persistence of inflation and the lucas critique evidence from exchange rate regimes comment we present evidence from the united states and the united kingdom that the persistence of price inflation is significantly higher under managed exchange rate regimes than under gold based fixed exchange rate regimes these differences are also reflected in expectations augmented phillips curves we use a two country macro model with forward looking price setters to demonstrate that higher monetary accommodation of inflation and exchange rate accommodation of inflation differentials increase inflation persistence the evidence does not contradict this hypothesis it supports the hypothesis of forward looking price setters and highlights the empirical significance of the lucas critique jel e31 e42 f33

fewer monies better monies in the aftermath of emerging market crises from russia to asia and latin america there is a quest for better monetary arrangements that are more crisis proof fixed rates are out flexible rates are in with a policy focus on inflation targeting but there is of course the alternative of abolishing exchange rates all together this paper revisits the issue of dollarization or currency boards to review what arguments in the debate stand up the case for flexible exchange rates emphasizes the need for a tool to accomplish relative price adjustment this paper argues that in an intertemporal perspective most shocks require financing in the capital market rather than adjustment moreover countries frequently do not use their flexible rate to play a cyclical role and as a result only a pay a premium for the option to depreciate but do not take advantage of the flexibility on the contrary they engineer systematic overvaluation in the context of inflation targeting
