cost of living inequality during the great recession using detailed barcode level data we construct income group specific price indices for the period of 2004 to 2010 we find substantial differences across income groups arising mainly during the great recession the annual cost of living inflation of the highest quartile has been on average 0 7 percentage points lower than that of the lowest quartile of the income distribution the difference can be explained by the way consumers adjusted their shopping behavior to mitigate the crisis we find that product quality substitution a margin mostly available to richer households is the main mechanism explaining the differences in cost of living inflation our evidence suggests that not accounting for these differences during economic downturns could lead to significant biases in the calculation of inequality and poverty measures jel classifications d12 e31 e32 we thank fernando alvarez erik hurst anil kashyap robert lucas and joseph vavra for their advice and support the paper benefited from comments and suggestions by many others including bong geun choi jorge l garcia jessie handbury sara moreira roberto robatto adriaan ten kate yike wang chen yeh and seminar participants at the university of chicago iea meeting washington university graduate student conference and the midwest macro meeting contacts david argente dargente uchicago edu munseob lee munseob uchicago edu

price setting in online markets does it click using a unique dataset of daily u s and u k price listings and the associated number of clicks for precisely defined goods from a major shopping platform we shed new light on how prices are set in online markets which have a number of special properties such as low search costs low costs of monitoring competitors prices and low costs of nominal price adjustment we document that although online prices are more flexible than offline prices they nevertheless exhibit relatively long spells of fixed prices large size and low synchronization of price changes considerable crosssectional dispersion and low sensitivity to predictable or unanticipated changes in demand conditions qualitatively these patterns are similar to those observed for offline prices a finding that suggests a need for more research on the sources of price rigidities and dispersion

liquidity constraints and deforestation the limitations of payments for ecosystem services abstract a popular environmental policy is to pay forest owners for avoiding deforestation on their land this is an example of payments for ecosystem services pes this paper shows that liquidity constraints can limit the effectiveness of pes programs if an individual would have cut down trees to sell them his opportunity costs are more front loaded than the stream of pes income if credit constrained he might decline the program even if the net present value npv of the pes income exceeds the npv of his opportunity costs i present evidence consistent with this prediction using data on forest owners in uganda

the permanent effects of innovation on financial depth abstract this paper examines links between innovation in the us intermediating sector and financial deepening from 1872 1929 technical progress is modeled in a credit rationing framework with limited liability as an enhanced ability of intermediaries to monitor loan recipients this allows an innovating lender to earn temporary rents by lowering loan rates and inducing firms with higher repayment prospects to apply rents persist until others adopt the improvement and competition for loanable funds raises the deposit rate subsequent deposits ensure that more funds are channeled to projects of higher average quality the link between the loan deposit spread and financial deepening implied by the model is then examined in an unobservable components framework the finding that permanent reductions of 1 in the spread of new york banks are associated with increases in financial depth that range from 1 7 to nearly 4 is consistent with a role for efficiency improvements in the rapid financial deepening that characterized the pre 1930 us economy

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

heterogeneity in the tax pass through to spirit retail prices evidence from belgium abstract on 1st november 2015 the belgian government increased the excise tax on alcoholic beverages for spirits with 40 of alcohol and bottle size of 70 cl this tax change is equivalent to an amount of 2 43 per bottle of spirits this paper studies the impact of this tax reform at the store level on the posted retail price of six major brands of spirits using a difference in differences method the estimation is based on a balanced panel of scanner data from a major supermarket chain with a 33 market share and uses the retail prices of the same brands sold in france by the same supermarket chain as a control group having information on each store location we show spatial variations in the tax pass through for homogeneous products we find that these variations are strongly related to the intensity of local competition and to a lesser extent to the proximity to the borders mainly with luxembourg which is the low price country we find that the tax was quickly passed through during the first month of tax implementation and that it was mostly over shifted however we also find that both the border and the competition effects are not instantaneous but arise several months after the tax reform these findings have important implications for alcohol control policies as they highlight that the incidence of alcohol taxation can vary greatly across space and affect differently households depending on where they live

inflation expectations as a policy tool abstract we assess the prospects for central banks using inflation expectations as a policy tool for stabilization purposes we review recent work on how expectations of agents are formed and how they affect their economic decisions empirical evidence suggests that inflation expectations of households and firms affect their actions but the underlying mechanisms remain unclear especially for firms two additional limitations prevent policy makers from being able to actively manage inflation expectations first available surveys of firms expectations are systematically deficient which can only be addressed through the creation of large nationally representative surveys of firms second neither households nor firms expectations respond much to monetary policy announcements in low inflation environments we provide suggestions for how monetary policy makers could pierce this veil of inattention through new communication strategies as well as the potential pitfalls to trying to do so

limited enforcement financial intermediation and economic development a quantitative assessment we present a model of economic development where the importance of financial differences caused by limited enforcement can be measured economies where enforcement is poor direct less capital to the production sector and employ less efficient technologies calibrated simulations reveal that the resulting effect on output is large furthermore the model correctly predicts that the average scale of production should rise with the quality of enforcement finally we find that the importance of limited enforcement rises with the importance of capital in production

time use during the great recession using data from the american time use survey between 2003 and 2010 we document that home production absorbs roughly 30 percent of foregone market work hours at business cycle frequencies leisure absorbs roughly 50 percent of foregone market work hours with sleeping and television watching accounting for most of this increase we document significant increases in time spent on shopping child care education and health job search absorbs between 2 and 6 percent of foregone market work hours we discuss the implications of our results for business cycle models with home production and non separable preferences jel codes d13 e32 j22

a new database on the structure and development of the financial sector this article introduces a new database of indicators of financial structure and financial development across countries and over time the database is unique in that it combines a wide variety of indicators that measure the size activity and efficiency of financial intermediaries and markets it improves on previous efforts by presenting data on the public share of commercial banks introducing indicators of the size and activity of nonbank financial institutions and constructing measures of the size of bond and primary equity markets this article introduces a new database the first to provide comprehensive measures of the development structure and performance of the financial sector this database is the first to define and construct indicators of the size and activity of nonbank financial intermediaries such as insurance companies pension funds and non deposit money banks it is also the first to include indicators of the size of primary equity markets and primary and secondary bond markets in constructing the database authors carefully deflate measures and match stock and flow variables

prices are sticky after all abstract economists have interpreted the evidence that prices change every four months as implying that sticky prices cannot be important for monetary transmission theory implies that this interpretation is correct if most price changes are regular but not if a large fraction are temporary as in the data since regular prices are much stickier than temporary ones our models predict that the stickiness of the aggregate price level matches that in a standard calvo model or a standard menu cost model in which micro level prices change about once a year in this sense prices are sticky after all

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

the optimal inflation rate in new keynesian models should central banks raise their inflation targets in light of the zero lower bound we study the effects of positive steady state inflation in new keynesian models subject to the zero bound on interest rates we derive the utility based welfare loss function taking into account the effects of positive steady state inflation and solve for the optimal level of inflation in the model for plausible calibrations with costly but infrequent episodes at the zero lower bound the optimal inflation rate is low typically less than two percent even after considering a variety of extensions including optimal stabilization policy price indexation endogenous and statedependent price stickiness capital formation model uncertainty and downward nominal wage rigidities on the normative side price level targeting delivers large welfare gains and a very low optimal inflation rate consistent with price stability these results suggest that raising the inflation target is too blunt an instrument to efficiently reduce the severe costs of zero bound episodes

communication commitment and growth abstract we study the effect on the growth of an economy of alternative financing opportunities in a stochastic growth model with incentive constraints efficient accumulation mechanisms are designed and computed for economies that differ in their incentive structure we show that when borrowing is subject to information constraints there is a computable efficient transfer mechanism that does not affect capital accumulation and investment patterns even though consumption patterns and the distribution of wealth are affected in contrast enforcement constraints can severely reduce the outside financing opportunities and affect investment patters and economic growth we adapt numerical algorithms for obtaining numerical solutions of these models

financial deepening inequality and growth a model based quantitative evaluation we propose a coherent unified approach to the study of the linkages among economic growth financial structure and inequality bringing together disparate theoretical and empirical literature that is we show how to conduct model based quantitative research on transitional paths with analytical and numerical methods we calibrate and make tractable a prototype canonical model and take it to an application namely thailand 1976 96 an emerging market economy in a phase of economic expansion with uneven financial deepening and increasing inequality we look at the expected path generated by the model and conduct robustness experiments because the actual path of the thai economy is imagined here to be just one realization of many possible histories of the model economy we construct a covariance normalized squared error metric of closeness and find the best fit simulation we also construct a confidence region from a set of simulations and formally test the model we broadly replicate the actual data and identify anomalies robert m townsend is a professor at the university of chicago and a consultant at the federal reserve bank of chicago kenichi ueda is an economist at the international monetary fund the views expressed in this paper are those of authors and do not necessarily represent those of the frb chicago the federal reserve system or the imf we thank the national statistics office of thailand for permission to use the ses data we received helpful comments from robin brooks fabio canova marco cagetti larry christiano angus deaton paul evans jess gaspar hyeok jeong ashok mody tomoyuki nakajima hajime takizawa chris udry annette vissing jorgensen and the participants of the nber general equilibrium conference at new york university the conference honoring rolf r mantel in argentina seminars at cornell university grips hitotsubashi university ohio state university oxford university and the imf as well as the imf conference on macroeconomic policy and poverty reduction we are especially indebted to the editors and referees townsend acknowledges financial support from the nsf and nichd we thank natalia ramondo for excellent research assistance

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

price dispersion and demand uncertainty evidence from u s scanner data i use the prescott 1975 hotels model to explain variations in price dispersion across items sold by supermarkets in chicago the effect of demand uncertainty on price dispersion is highly significant and quantitatively important my estimates suggest that more than 40 of the cross sectional standard deviation of log prices is due to demand uncertainty i also find that price dispersion measures are negatively correlated with the average price but are not negatively correlated with the revenues from selling the good across stores and weeks and with the number of stores that sell the good temporary sales are modeled as a reaction to unwanted inventories that are accumulated when the realization of demand is low the effect of demand uncertainty on the frequency of temporary sales is also highly significant and quantitatively important items with more demand uncertainty tend to accumulate unwanted inventories more often and tend to have temporary sales more often

appropriate technology and income differences this article studies the relative productivity of skilled to unskilled workers across countries relative productivities are broken down into the human capital embodied in skilled workers and relative physical productivities reflecting production techniques i find that skilled workers from poorer countries embody less human capital and are also relatively less physically productive furthermore results show that production techniques are inappropriate for most low income countries and these countries experience large increases in gdp per capita by increasing the relative physical productivity of skilled to unskilled workers this suggests that there are significant barriers to the adoption of skill complementary technologies

the penn balassa samuelson effect through the lens of the dependent economy model abstract the positive correlation between per capita income and cross country price levels is called the penn balassa samuelson effect the most influential explanation of this effect centers around sectoral output productivities as the determinant of the relative price of nontraded goods the interaction between the change in relative prices and the change in per capita income the dynamic pbs effect is less well known this paper extends the turnovsky and sen 1995 model of a small open economy by adding external economies into the production function the model s dynamics accord well with several features of the empirical data on the dynamic pbs effect

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

do property rights promote investment but cause deforestation quasi experimental evidence from nicaragua abstract many policymakers argue that property rights decrease deforestation some theoretical papers also make this prediction arguing that property rights decrease discount rates applied to a long term investment in forestry however the effect is theoretically ambiguous the paper takes a novel instrumental variables approach based on nicaragua s agrarian reform to test for the effect using a new dataset nicaragua s 2001 agricultural census it finds that property rights significantly increase deforestation the model supported by the data suggests a likely mechanism for this relationship property rights increase investment increasing agricultural productivity and therefore the returns to deforestation

informational rigidities and the stickiness of temporary sales abstract how do retailers react to cost changes while temporary sales account for 95 of price change in our data retail prices respond to a wholesale cost increase entirely through the regular price sales actually respond temporarily in the opposite direction from regular prices as though to conceal the price hike additional evidence from responses to commodity cost and local unemployment shocks as well as broader evidence from bls data reinforces these findings institutional evidence indicates that sales are complex contingent contracts determined substantially in advance in a standard price discrimination model these institutional practices leave little money on the table

how good are standard debt contracts stochastic versus nonstochastic monitoring in a costly state verification environment the authors investigate ex ante efficient contracts in an environment in which implementation is costless in this environment standard debt contracts will typically not be optimal optimal contracts may involve defaults even in states in which the borrower is fully able to repay the authors then examine the welfare costs of arbitrarily restricting the set of feasible contracts to standard debt contracts when model parameters are calibrated to realistic values the welfare loss from exogenously imposing this restriction is extremely small thus if implementation costs are actually nontrivial as seems likely standard debt contracts will be very close to optimal copyright 1994 by university of chicago press

costly intermediation and the poverty of nations this article has two goals i to reduce the 7 fold productivity differential required to explain the observed 33 fold income difference between the richest and poorest countries of the world and ii to explain cross country differences in the capital output ratio to achieve the first goal we modify the production function of the standard neoclassical growth model to include public capital whose provision is subject to intermediation costs for the second goal we distort private investment by introducing credit frictions the model quantified using cross country data generates an income gap of 33 with productivity differences of only 3 under the measured variations in public and private capital the required productivity gap declines even further to 2 1 when we introduce a home production sector on the second goal however credit frictions do a poor job of explaining cross country variations in the capital output ratio

financial frictions occupational choice and economic inequality we develop a quantitative theory of entrepreneurship income inequality and nancial frictions disciplined with household data from brazil the theory extends lucas 1978 by modeling heterogeneity in two skills working and managerial skills consistently with the evidence the theory implies three occupational categories workers employers and self employed entrepreneurs we nd that the correlation between working and managerial skills matters importantly for the distribution of earnings across occupations and for the quantitative implications of nancial frictions we also nd

monetary policy trend inflation and the great moderation an alternative interpretation with positive trend inflation the taylor principle does not guarantee a determinate equilibrium we provide new theoretical results on determinacy in new keynesian models with positive trend inflation and new empirical findings on the federal reserve s reaction function before and after the volcker disinflation to find that i while the fed likely satisfied the taylor principle before volcker the us economy was still subject to self fulfilling fluctuations in the 1970s ii the us economy switched to determinacy during the volcker disinflation and iii the switch reflected changes in the fed s response to macroeconomic variables and the decline in trend inflation jel e12 e23 e31 e32 e52

the aggregate implications of regional business cycles during the last recession and its aftermath aggregate price growth and aggregate nominal wage growth remained robust despite the high rate of unemployment we document that u s states with weaker labor markets experienced lower price growth lower nominal wage growth and lower real wage growth during the great recession given that reliable measures of local prices do not exist we create our own state price indices using scanner data from the nielsen retail scanner database the main innovation of the paper is the development of an econometric procedure that combines cross region data with aggregate time series data to infer the underlying shocks driving both aggregate and regional business cycles applying our procedure to the great recession we find that a combination of both demand and supply shocks are necessary to account for the joint dynamics of aggregate prices wages and employment during the 2007 2012 period in contrast we find that only demand shocks are needed to explain the cross region variation the results suggest that only using cross region variation to explain aggregate fluctuations is insufficient when shocks do not have a substantive regional component

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

dynamic credit relationships in general equilibrium abstract we construct a general equilibrium model with private information in which borrowers and lenders enter into long term dynamic credit relationships each new generation of ex ante identical individuals is divided in equilibrium into workers and entrepreneurs workers save through financial intermediaries in the form of interest bearing deposits and supply labor to entrepreneurs in a competitive labor market entrepreneurs borrow from financial intermediaries to finance projects which produce privately observed sequences of random returns each financial intermediary holds deposits from a large number of workers and operates a portfolio of dynamic contracts with different credit positions we calibrate the model to the u s economy and find that dynamic contracting is very effective at mitigating the effects of private information moreover restricting borrowers and lenders to use static one period contracts with a costly monitoring technology has adverse effects both on the level of aggregate economic activity and on individual welfare unless monitoring costs are very small finally the optimal provision of intertemporal incentives leads to increasing consumption inequality over time within generational cohorts as in u s data

general equilibrium tragedy of the commons many poor economies depend on open access resources for their livelihoods households in resource based economies allocate their time and other factors between resource extraction and other activities as a result factors may shift from one sector to another as marginal returns change this has two important implications first it implies potentially strong linkages between resource and non resource sectors second it means that unmanaged resources cause inefficient allocations of inputs across all sectors and the effects of resource management spill into other sectors we construct a local general equilibrium model that accounts for inputs that over allocate to an open access resource and create a general equilibrium tragedy of the commons this model describes resource rent dissipation more adequately in economies with mobile factors than a model with slowly dissipating rents perfectly mobile factors dissipate rent in every period but endogenous wages cause labor and capital allocations to change with the resource stock we use the model to illustrate medium run impacts of a limit on capital in an artisanal fishery in honduras simulation results reveal that fishery management has economy wide impacts on prices and wages managers in developing countries thus should consider these linkages when implementing policies to conserve fish stocks

a theory of financing constraints and firm dynamics there is widespread evidence supporting the conjecture that borrowing constraints have important implications for firm growth and survival in this paper we model a multiperiod borrowing lending relationship with asymmetric information we show that borrowing constraints emerge as a feature of the optimal long term lending contract and that such constraints relax as the value of the borrower s claim to future cash flows increases we also show that the optimal contract has interesting implications for firm dynamics in agreement with the empirical evidence as age and size increase mean and variance of growth decrease and firm survival increases

the cross sectional distribution of price stickiness implied by aggregate data we provide evidence on three mechanisms that can reconcile frequent individual price changes with sluggish aggregate price dynamics to that end we estimate a semistructural model that can extract

financial capacity and output fluctuations in an economy with multi period financial relationships this paper motivates a financial propagation mechanism in the context of an intertemporal production economy with asymmetric information and with borrowers and lenders who enter multi period financial relationships a key feature is that aggregate output and borrowers financial capacity the maximum overhang of past debt they may feasibly carry are determined jointly much in the spirit of gurley and shaw 1955 expectations of future economic conditions govern financial capacity which in turn may constrain current production especially in bad times a small but persistent shift in aggregate conditions may have a large impact on financial capacity making the framework capable of motivating large endogenous fluctuations in financial constraints understanding how small disturbances can induce large output fluctuations is an on going quest in macroeconomics this paper develops a simple framework in which shifts in aggregate economic fundamentals are amplified through their impact on financial conditions a distinguishing feature is that output and borrowers financial capacity the maximum overhang of past debt they may feasibly carry are determined jointly much in the spirit of gurley and shaw 1955 expectations of future economic conditions govern financial capacity and financial capacity may constrain current production especially in bad times a number of recent papers have resurrected the view that financial factors may play a part in propagating business fluctuations the underlying theories exploit the idea that with asymmetric information between borrowers and lenders agency costs may drive the price of uncollateralized external funds above the price of internal funds in this kind of setting a borrower s financial position is a key determinant of the terms of credit she faces in the aggregate swings in borrower balance sheets over the cycle amplify fluctuations in investment and output essentially by inducing counter cyclical movements in the required premium for external finance this simple mechanism is broadly consistent with informal descriptions of how financial and real variables interacted in the great depression bernanke 1983 and in the postwar business cycles eckstein and sinai 1986 in addition numerous recent panel data studies beginning with fazzari hubbard and peterson 1988 support the notion of a financial investment accelerator mechanism

firm dynamics and pricing under customer capital accumulation abstract in a search model of firm dynamics customer accumulation is shown to affect the lifecycle of firms and the dynamics of markups in response to aggregate demand shocks in the model sellers of different sizes and productivities post dynamic pricing contracts to strike a balance between attracting new customers and exploiting pre existing ones calibrated using establishment level and micro pricing data from the u s retail sector the model provides a quantitatively good fit to the lifecycle and cross sectional properties of retail establishments further the model predicts that markups are procyclical to aggregate demand shocks with a larger contribution by small sellers

monetary policy when potential output is uncertain understanding the growth gamble of the 1990s abstract t he fed kept interest rates low and essentially unchanged during the late 1990s despite a booming economy and record low unemployment these interest rates were accommodative by historical standards nonetheless inflation remained low how did the fed succeed in sustaining rapid economic growth without fueling inflation and inflationary expectations in retrospect it is evident that the productive capacity of the economy increased yet as events unfolded there was uncertainty about the expansion of the capacity of the economy and therefore about the sustainability of the fed s policy this paper provides an explanation for the success of the fed in accommodating growth with stable inflation in the late 1990s it shows that if the central bank is committed to reverse policy errors it makes because of unwarranted optimism inflation can remain in check even if the central bank keeps interest rates low because of this optimism in particular a price level target which is a simple way to model a commitment to offset errors can serve to anchor inflation even if the public does not share the central bank s optimism about shifts in potential output the paper shows that price level targeting is superior to inflation targeting in a wide range of situations the paper also provides econometric evidence that in contrast to earlier periods the fed has recently put substantial weight on the price level in setting interest rates moreover it shows that cpi announcement surprises lead to reversion in the price level finally it provides textual evidence that alan greenspan puts relatively more weight on the price level than inflation

market structure and cost pass through in retail abstract we examine the extent to which vertical and horizontal market structure can together explain incomplete retail pass through to answer this question we use scanner data from a large u s retailer to estimate product level pass through for three vertical structures national brands private label goods not manufactured by the retailer and private label goods manufactured by the retailer our approach circumvents issues associated with internal firm prices and demonstrates that accounting for horizontal market structure is important for measuring the effects of vertical integration and reduced double marginalization on pass through

on finance as a theory of tfp cross industry productivity differences and economic rents we develop a theory of capital market imperfections to study how the ability to enforce contracts affects resource allocation across entrepreneurs of different productivities and across industries with different needs for external financing the theory implies that countries with a poor ability to enforce contracts are characterized by the use of inefficient technologies low aggregate tfp large differences in labor productivity across industries and large employment shares in industries with low productivity these implications are supported by the empirical evidence the theory also suggests that entrepreneurs have a vested interest in maintaining a status quo with low enforcement

price stickiness along the income distribution and the effects of monetary policy abstract monetary shocks have distributional consequences if they affect relative prices across goods consumed by different households we document that the prices of the goods consumed by high income households are stickier and less volatile than those of the goods consumed by middle income households following a monetary policy shock the estimated impulse responses of high income households consumer price indices are about one third smaller than those of the middle income households we evaluate the implications of these findings in a quantitative multi sector new keynesian model featuring heterogeneous households the distributional consequences of monetary policy shocks are large and similar to those in the econometric model

why doesn t technology flow from rich to poor countries what determines the technology that a country adopts while there could be many factors the e ciency of the country s nancial system may play a signi cant role to address this question a dynamic contract model is embedded into a general equilibrium setting with competitive intermediation the ability of an intermediary to monitor and control the cash ows of a rm plays an important role in a rm s decision to adopt a technology can such a theory help to explain the

the timing and magnitude of retail store markdowns evidence from weekends and holidays we examine daily prices of eight goods at seventeen retail stores collected in ann arbor michigan over a four month period from november 1 to february 28 we focus on weekly and seasonal price patterns and on the frequency of price markdowns or sales there were frequent markdowns in the intensive shopping period prior to christmas and a tendency for such sales to occur on weekends we interpret these findings as evidence that a significant number of markdowns are timed to occur when shopping intensity is exogenously high we complement the imperfect information based motives for sales in the literature by contributing an additional element based on the role of bulk shopping and increasing returns in the shopping technology

bankruptcy and delinquency in a model of unsecured debt this article documents and interprets a fact central to the dynamics of informal consumer debt default we observe that for individuals 60 90 days late on payments i 85 make payments during the next quarter and ii 40 reduce their debt to understand these facts we develop a quantitative model of debt delinquency and bankruptcy our model reproduces the dynamics of delinquency and suggests an interpretation of the data in which lenders frequently reset loan terms for delinquent borrowers typically offering partial debt forgiveness instead of a blanket imposition of the penalty rates most unsecured credit contracts specify

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

price elasticities and demand side real rigidities in micro data and in macro models abstract high degrees of demand side real rigidities are able to generate the large monetary non neutrality found in aggregate data this paper provides micro based evidence on the key parameters governing this rigidity using european homescan data we find strong evidence for demand side real rigidity which is however significantly lower than that normally assumed in macro models in a menu cost model calibrated to our estimates we show that these estimates are associated with reasonable values for production side parameters but they are not able to generate the degree of monetary non neutrality observed in macro data

gluttony and sloth calories labour market activity and the rise of obesity the rise in obesity has largely been attributed to an increase in calorie consumption we show that official government household survey data indicate that levels of calorie consumption have declined in england between 1980 and 2013 while there has been an increase in calories from food eaten out at restaurants fast food soft drinks and confectionery overall there has been a decrease in total calories purchased households have shifted towards more expensive calories both by substituting away from home production towards market production and substituting towards higher quality foods we show that the decline in calories can be partially but not entirely rationalized with weight gain by a decline in the strenuousness of work and daily life jel d12 i12 i18

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

the elasticity of substitution between time and market goods evidence from the great recession the elasticity of substitution between time and market goods we document a change in household shopping behavior during the great recession households purchased more on sale larger sizes and generic products increased coupon usage and shopping at discount stores we estimate that the returns to these shopping activities declined during the recession and therefore this behavior implies a significant decrease in households opportunity cost of time using the estimated cost of time and time use data we estimate a high elasticity of substitution between market expenditure and time spent on non market work we find that households smooth a sizable fraction of consumption by varying their time allocation during recessions institutional subscribers to the nber working paper series and residents of developing countries may download this paper without additional charge at www nber org

nature in economics nature has been ill served by 20th century economics when asked economists acknowledge nature s existence but most would appear to deny that she is worth much if ecologists worry about the contemporary nexus between population size and growth the standard of living and the natural environment we economists point to the accumulation of capital and technological progress and say malthus got it wrong in this paper i show by an appeal to theory that economics has been so badly misused that it has deflected attention from deep problems at the nexus that are faced both regionally and globally

the profits of power land rights and agricultural investment in ghana we examine the impact of ambiguous and contested land rights on investment and productivity in agriculture in akwapim ghana we show that individuals who hold powerful positions in a local political hierarchy have more secure tenure rights and that as a consequence they invest more in land fertility and have substantially higher output the intensity of investments on different plots cultivated by a given individual corresponds to that individual s security of tenure over those specific plots and in turn to the individual s position in the political hierarchy relevant to those specific plots

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

competition human capital and income inequality with limited commitment we develop a dynamic general equilibrium model with two sided limited commitment to study how barriers to competition such as re strictions to business start up aect the incentive to accumulate hu man capital we show that a lack of contract enforceability ampli es the eect of barriers to competition on human capital accumulation high barriers reduce the incentive to accumulate human capital by lowering the outside value of skilled workers while low barriers can result in over accumulation of human capital this over accumulation can be socially optimal if there are positive knowledge spillovers a calibration exercise shows that this mechanism can account for signif icant cross country income inequality

income induced expenditure switching abstract this paper shows that an income effect can drive expenditure switching between domestic and imported goods we use a unique latvian scanner level dataset covering the 2008 2009 crisis to document several empirical findings first expenditure switching accounted for one third of the fall in imports and took place within narrowly defined product groups second there was no corresponding within group change in relative prices third consumers substituted from expensive imports to cheaper domestic alternatives these findings motivate us to estimate a model of nonhomothetic consumer demand which explains two thirds of the observed expenditure switching estimated switching is driven by income not changes in relative prices jel e21 f14 f31 f32 i11 l81

the information technology revolution and the stock market evidence since 1968 the ratio of stock market capitalization to gdp has varied by a factor of 5 in 1972 the ratio stood at above unity but by 1974 it had fallen to 0 45 where it stayed for the next decade it then began a steady climb and today it stands above 2 we argue that the it revolution was behind this and moreover that the capitalization gdp ratio is likely to decline and then rise after any major technological shift the three assumptions that deliver the result are

when is the standard analysis of common property extraction under free access correct a game theoretic justification for non game theoretic analyses analyses of common property extraction under free access follow two distinct paths traditional and game theoretic giving rise to two standard methodologies one methodology avoids game theoretic analysis by assuming that aggregate extraction in each period induces fel rent dissipation the second methodology solves for the marko perfect equilibrium of an n player extraction game investigating aggregate behavior over time as n we show by example that these coexisting standard methodologies can yield conflicting predictions we then provide conditions relatively easy to satisfy sufficient for the two approaches to yield the same predictions

free access versus private property in a resource income distributions compared distributions of income are compared under the alternative regimes of free access to and private property in a resource it is shown that in several analytically distinct cases all those deprived of free access on conversion of a resource to private property can be better off even though no compensating transfers are made this resu lt can hold even if the granting of private property rights also conf ers monopoly or monopsony power copyright 1987 by university of chicago press

uniform pricing in us retail chains we show that most u s food drugstore and mass merchandise chains charge nearly uniform prices across stores despite wide variation in consumer demographics and competition demand estimates reveal substantial within chain variation in price elasticities and suggest that the median chain sacrifices 16 million of annual profit relative to a benchmark of optimal prices in contrast differences in average prices between chains are broadly consistent with the optimal benchmark we discuss a range of explanations for nearly uniform pricing highlighting managerial inertia and brand image concerns as mechanisms frequently mentioned by industry participants relative to our optimal benchmark uniform pricing may significantly increase the prices paid by poorer households relative to the rich dampen the response of prices to local economic shocks alter the analysis of mergers in antitrust and shift the incidence of intranational trade costs

supermarket competition the case of every day low pricing every day low pricing edlp strategy has proved to be a successful innovation resulting in higher profits to supermarkets adopting it in competition with promotional pricing promo conventional wisdom attributes this success either to lower costs or to edlp better serving time constrained consumers while discouraging cherry pickers who seek promotions however it is unclear that such cost savings are being fully realized since edlp stores also engage in price promotions also continued existence of promo stores means that costs are not the only factor and they compete effectively without relying just on the cherry pickers furthermore experimental evidence suggests that a supermarket cannot obtain higher profits by merely setting constant low prices leading to the question exactly what makes edlp successful this question is of particular relevance to both academics and practitioners who have been intrigued by the success of this retailing strategy more generally the retailing issues addressed in this paper the economic analysis of competition and the empirical findings should be of interest to the broader community of researchers and managers we investigate the factors contributing to edlp s success by analyzing the competition between supermarkets through a game theoretic analysis of a market consisting of both time constrained consumers and cherry pickers key features of our model are consumers shop and purchase a basket of goods based on price announcements by stores and rational expectations of unannounced prices stores carry more than one good and compete through prices service convenience and appropriate communication strategies and no exogenous cost asymmetries we derive the conditions under which retailers choosing different strategies edlp and promo is a perfect nash equilibrium our analysis shows that the edlp store s offering of constant every day low prices is an equilibrium outcome endogenously determined successful implementation of the edlp strategy involves communication of relative basket prices implying that merely setting constant low prices is not viable we further demonstrate that while time constrained consumers find every day low prices at edlp attractive and cherry pickers the promotions at promo clientele effects are in fact more complicated specifically in equilibrium the promo store offers a higher service level as desired by time constrained consumers and the edlp store a lower service level in keeping with the needs of cherry pickers this choice of service by the two stores results in a cleaner segmentation of the market the higher relative basket price and service at the promo store results in a larger base of time constrained consumers to shop at the promo store and a larger base of cherry pickers to shop at the edlp store even though some cherry pickers continue to visit the promo store to avail of the price specials in this way our results contradict the conventional wisdom on edlp strategy as being mainly geared towards time constrained consumers finally industry profits are higher in an edlp promo equilibrium than when stores adopt identical strategies our analysis and results also offer a more complete characterization of the edlp and promo strategies indeed we show that edlp and promo strategies are positioning strategies rather than merely pricing strategies with different elements price promotions service and communications while the edlp store uses basket prices to attract both segments the promo store uses service and price specials to compete in the time constrained and cherry picking segment respectively given these different approaches of the two stores the communication strategies of the edlp and the promo stores emphasize these differences as well in this way we show as suggested by corstjens and corstjens 1994 that positioning in a retail context involves developing multidimensional strategies appealing to all segments while each element of the strategy may focus on a different consumer segment this is in contrast to the traditional view of segmentation in which different products in a product line for example are designed to appeal to different segments we complete the analysis by examining the data from the trade press and a survey conducted in a major metropolitan area these data while limited in scope support our theoretical results

consumption versus expenditure previous authors have documented a dramatic decline in food expenditures at the time of retirement we show that this is matched by an equally dramatic rise in time spent shopping for and preparing meals using a novel data set that collects detailed food diaries for a large cross section of u s households we show that neither the quality nor the quantity of food intake deteriorates with retirement status we also show that unemployed households experience a decline in food expenditure and food consumption commensurate with the impact of job displacement on permanent income these results highlight how direct measures of consumption distinguish between anticipated and unanticipated shocks to income whereas measures of expenditures obscure the distinction

price dispersion and inflation new facts and theoretical implications abstract in workhorse macroeconomic models price dispersion is a central determinant of welfare the cost of business cycles optimal inflation and the tradeoff between inflation and output stability while price dispersion increases with inflation in the models this relationship is negative in the data due to sales prices the comovement of price dispersion and inflation for regular prices is positive a model with sales can quantitatively match the comovement in the data whereas a range of similar models without sales cannot even for regular prices these findings have important implications for welfare calculations optimal inflation and the effects of monetary shocks

financial intermediary coalitions abstract in this article an environment in which the investment opportunities of agents are private information is studied and it is shown that financial intermediaries arise endogenously within that environment it is established that financial intermediaries are part of an efficient arrangement in the sense that they are needed to support the authors private information core allocations these intermediaries which are coalitions of agents exhibit the following characteristics in equilibrium they borrow from and lend to large groups of agents they produce information about investment projects and they issue claims that have different state contingent payoffs than claims issued by ultimate borrowers

optimal monetary policy responses to relative price changes abstract an optimizing model with a flexible price sector and a sticky price sector is presented to analyze the effects of relative price changes on inflation fluctuations the relative price of the flexible price good represents a shift parameter of the new keynesian phillips curve the optimal monetary policy is to target sticky price inflation rather than a broad inflation measure although stabilizing the relative price around its efficient value is one of the appropriate goals of the central bank stabilizing sticky price inflation is sufficient for achieving this goal an optimal monetary policy for a small open economy is also discussed

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

sales and firm entry the case of wal mart temporary price reductions or sales have become increasingly important in the evolution of the price level we present a model of repeated price competition to illustrate how entry causes incumbents to alternate between high and low prices using a six year panel of weekly observations from a grocery chain we find that individual stores employ more sales as the distance to wal mart falls moreover the increase in the frequency of sales was concentrated on the most popular products suggesting the use of a loss leader strategy

working less and bargain hunting more macro implications of sales during japan s lost decades standard new keynesian models have often neglected temporary sales in this paper we ask whether this treatment is appropriate in the empirical part of the paper we provide evidence using japanese scanner data covering the last two decades that the frequency of sales was closely related with macroeconomic developments specifically we find that the frequency of sales and hours worked move in opposite directions in response to technology shocks producing a negative correlation between the two we then construct a dynamic stochastic general equilibrium model that takes households decisions regarding their allocation of time for work leisure and bargain hunting into account using this model we show that the rise in the frequency of sales which is observed in the data can be accounted for by the decline in hours worked during japan s lost decades we also find that the real effect of monetary policy shocks weakens by around 40 due to the presence of temporary sales but monetary policy still matters

more facts about prices france before and during the great recession using microprice data we document new facts on price rigidity in france i each month 20 1 of prices are changed which compares to 24 1 in the united states excluding sales however the fraction of prices modified each month is about the same in france and in the united states around 17 ii the distribution of price changes is quite dispersed iii the frequencies of price increases and decreases contribute a lot to inflation variations and price increases are more frequent in january even when sales are excluded iv sales contribute significantly to the volatility of inflation but play a minor role in the transmission of macroeconomic fluctuations to prices and v during the great recession patterns of price adjustment were only slightly modified

credit market frictions and their direct effects on u s manufacturing fluctuations abstract in this paper we explore how informational frictions in credit markets directly affect u s manufacturing fluctuations within the context of a dynamic industry model we propose a strategy for identifying intermediation costs related to informational asymmetries between lenders and borrowers the analysis suggests that these costs have been steadily falling over the post war period we also present evidence that changes in the cost of intermediation should directly affect output as opposed to just propagating the effects of other shocks in particular we find that shocks to the cost of intermediation account for a larger share of manufacturing output fluctuations at long horizons than at short horizons

variety pass through an examination of the ready to eat breakfast cereal market abstract we examine variety pass through effects that occur when multiproduct retailers adjust the length of their product lines in response to changes in wholesale prices studying variety pass through is essential to understanding how wholesale price changes transmit into retail prices when variety is endogenous using data from the ready to eat breakfast cereal category we find that retailers jointly adjust retail prices and the length of their product lines in response to changes in wholesale prices we show the importance of controlling for the endogeneity of retailers product line decisions when calculating price pass through rates

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

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

rent dissipation and efficient rationalization in for hire recreational fishing abstract recreational fisheries are increasingly important in fisheries management for some species recreational take rivals or exceeds the amount harvested by commercial fishermen most recreational fisheries are regulated with gear restrictions bag limits and time area closures but there is increasing interest in the market based solutions employed in commercial fisheries this despite the lack of an adequate bioeconomic theory of the joint commercial recreational aspects of many recreational fisheries this paper integrates a detailed production specification with traditional bioeconomic tools in order to better understand the implications of rationalization schemes targeted at the charter sector while confirming some of the qualitative conclusions of the commercial fisheries literature on open access and regulated open access our model also generates rich and novel predictions with respect to input choices the number of vessels and congestion externalities we devise a system of instruments that generate efficient outcomes and extensively discuss issues associated with their real world implementation

price setting in online markets basic facts international comparisons and cross border integration we document basic facts about prices in online markets in the united states and canada which is a rapidly growing segment of the retail sector relative to prices in regular stores prices in online markets are more flexible and exhibit stronger pass through 60 75 percent and faster convergence half life less than two months in response to movements of the nominal exchange rate multiple margins of adjustment are active in the process of responding to nominal exchange rate shocks properties of goods sellers and markets are systematically related to pass through and the speed of price adjustment for international price differentials

agricultural spillover effects of cash transfers what does lewie have to say lewie simulations suggest that there are positive production spillovers fromsctprograms in nominal terms total production multipliers are always significantly greater than zero and income multipliers are always greater than one however real impacts depend on supply elasticities and market closure assumptions to date studies do not point to inflationary impacts of scts opm 2012a opm 2012b although the evidence on price effects is very limited this suggests that simulation 2 best characterizes the production impacts of scts which target poor economies with under utilized factors this simulation reveals a minimal inflationary impact and real production value added multipliers of 1 58 ksh per shilling transferred a key finding of lewie is that the production impacts are concentrated in nonbeneficiary households this is not surprising given the program s eligibility criteria which target the most asset and labor constrained households rcts focusing on treated households are likely to miss many or most of the productive impacts of social cash transfer programs this finding reaffirms the importance of a local economy wide approach if we wish to capture the transfers full impact finally our findings underline the importance of local supply constraints in shaping the impacts of transfer programs in the high unemployment environment characterizing rural kenya we believe it unlikely that there are significant labor constraints on production nevertheless production constraints limit program benefits particularly in nonbeneficiary households which are far and away the main source of new supply when production bottlenecks generate inflation transfers may even negatively affect some households interventions focusing on local production constraints in nonbeneficiary as well as beneficiary households may be needed to unlock the productive potential of scts

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

investor protection optimal incentives and economic growth does investor protection foster economic growth to assess the widely held affirmative view we introduce investor protection into a standard overlapping generations model of capital accumulation better investor protection implies better risk sharing because of entrepreneurs risk aversion this results in a larger demand for capital this is the demand effect a second effect the supply effect follows from general equilibrium restrictions better protection i e higher demand increases the interest rate and lowers the income of entrepreneurs decreasing current savings and next period s supply of capital the supply effect is stronger the tighter are the restrictions on capital flows our model thus predicts that the positive effect of investor protection on growth is stronger for countries with lower restrictions cross country data provide support for this prediction as does the detailed examination of the growth experiences of south korea and india

shopping around how households adjusted food spending over the great recession over the great recession real wages stagnated and unemployment increased concurrently food prices rose sharply outstripping growth in food expenditure and leading to a reduction in calories purchased this has led to concern about rising food poverty we study british households to assess how they adjusted to changes in the economic environment we show they switched to cheaper calories implying food consumption was smoother than expenditure we use longitudinal data to quantify the way households lowered their per calorie spending and show they done this in part by increasing shopping eort and without lowering the nutritional quality of
