declining values and the afternoon effect evidence from art auctions we study the order of sale in art auctions the final bid relative to the auctioneer s estimated price declines throughout the course of an auction a theoretical model shows that in an auction ordered by declining valuation even in the presence of risk neutral strategic bidders the price received relative to the estimate for later items in an auction should be less than the price relative to the estimate for earlier items furthermore ordering heterogeneous items by value maximizes revenue for the auctioneer

bidding behavior at sequential first price auctions with out supply uncertainty a laboratory analysis abstract we report on a series of experiments that test the effects of an uncertain supply on bidding behavior and prices in sequential first price auctions with private independent values and unit demands supply is assumed uncertain when buyers do not know the exact number of units to be sold i e the length of the sequence we observe an important overbidding in all but the last stage of a sequence no matter whether supply is certain and a non monotone behavior when supply is certain yet the data qualitatively support most stage to stage bid predictions and the price trend predictions for risk neutral bidders

economic mobility and poverty dynamics in developing countries this study provides an introduction to this special issue of the journal of development studies on economic mobility and poverty dynamics in developing countries in addition to providing a conceptual framework it outlines how the contributions fit into the extant literature a series of regularities emerge across these studies the poor consist of those who are always poor poor at all dates and those who move in and out of poverty with the latter group tending to be strikingly large such movements in and out of poverty are apparent when looking at poverty in either absolute or relative terms changes in returns to endowments can be a potent source of increased incomes finally seemingly transitory shocks can have long term consequences the study concludes by drawing out the policy implications of these regularities

testing for price anomalies in real estate auctions this paper reports on the results of an auction sale of 83 condominium apartment units in new jersey at the auction every unit was hammered down but unknown to the 2 348 registered bidders 40 of the sales fell through prices in the subsequent sale of condominium units in face to face negotiations resulted in identical units selling for 13 less than they fetched at auction and the discount was largest for those units hammered down early in the auction these results are inconsistent with the usual predictions from the theory of common value auctions and suggest that uninformed bidders in this auction may have been the subject of a winner s curse which generated considerable profit for the seller this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from ano this abstract was borrowed from another version of this item

intragenerational income mobility in latin america economic mobility has not been widely studied in developing countries until very recently owing to the lack of suitable data studying mobility requires longitudinal data tracking economic units that is individuals households or firms over time collecting this type of data is expensive and historically few latin american countries carried it out now however such data sets are available for a number of latin american and caribbean countries table a 1 in the appendix provides a list of available panel data sets that can be used for income mobility studies for these countries in this paper we discuss how the knowledge gleaned from mobility studies differs from comparable cross sectional analysis the structure of the paper is as follows the next section discusses what mobility is how it can be measured and how it differs from inequality the subsequent section reviews previous mobility studies in latin american countries the paper then summarizes the contributions of our own recent work and the final section discusses what lies ahead in mobility research for latin american economies

agents ability to manage information in centralized markets comparing two wholesale fish markets abstract in this paper we perform an empirical investigation to detect if and how agents behavior changes with the amount of available information they have to this aim we use data from two wholesale fish markets of different thicknesses we tackle the issue by investigating features such as the dynamics of the structure of attendance in auctions the varieties of fish presentations during the seller s turn and the presence of long term relationships between buyers and sellers we perform the investigation in this way instead of focusing on the dispersion and dynamics of prices to prevent unobserved quality differences of the traded fish varieties from biasing the results of the analysis the results of our investigation are consistent with a situation in which the magnitude of phenomena like buyers loyalty to sellers and agents following rules of thumb increases with the market thickness

a simultaneous equation analysis of advertising concentration and profitability nearly two decades of econometric research have been completed in testing relationships between industrial market structure and performance recently a number of authors have reexamined these studies and cautioned on a number of conceptual difficulties which subject the results and interpretation of previous empirical work to question one primary criticism of previous research has been the failure to account for the simultaneous nature of the interrelation among elements of industry structure conduct and performance 2 4 5 11 22 25 30 while the determinants of variables such as profits advertising and concentration have been examined separately within the context of single equation models the underlying theory suggests that these variables are more properly considered as jointly determined within a system of simultaneous equations estimation of single equation models when a simultaneous system is appropriate leads to parameter estimates that are both biased and inconsistent previous empirical studies of the structure performance relationship have also suffered due to the omission of certain critical variables first the role of international trade as an element of market structure has yet to be generally incorporated into empirical studies in spite of recent theoretical work that has demonstrated its potential importance 3 20 21 second interindustry differentials in the price elasticity of demand have been neglected even though theoretical analysis clearly underscores the necessity of explicity accounting for

evolving market structure an ace model of price dispersion and loyalty we present an agent based computational economics ace model of the wholesale sh market in marseille two of the stylized facts of that market are high loyalty of buyers to sellers and persistent price dispersion although it is every day the same population of sellers and buyers that meets in the same market hall in our ace model sellers decide on quantities to supply prices to ask and how to treat loyal customers while buyers decide which sellers to visit and which prices to accept learning takes place through reinforcement the model explains both stylized facts price dispersion and high loyalty in a coevolutionary process buyers learn to become loyal as sellers learn to o er higher utility to loyal buyers while these sellers in turn learn to o er higher utility to loyal buyers as they happen to realize higher gross revenues from loyal buyers the model also explains the e ect of heterogeneity of the buyers we analyze how this leads to subtle di erences in the shopping patterns of the di erent types of buyers and how this is

interpreting a correlation between market structure and performance certain types of controlled experiments may enable causal inferences to be made about the relationship between two variables other types of experiments can be used to deal with the not completely unrelated notions of consistency in estimation exogeneity of variables and with temporal ordering generally however causal interpretations of a relationship are simply imposed on the data by appeal to an underlying theory in this paper we shall examine the theoretical basis of profits concentration correlations arguing that such correlations cannot be given a causal interpretation of the conventional kind running from structure to performance section iii 1 lest this conclusion seem to undermine the basis for anti trust policy we shall also argue that such erroneous causal interpretations are unnecessary in making a case for intervention based on structure although they do direct attention towards inappropriate targets profits concentration regressions play a role it will be argued mainly in the derivation of intervention rules section iii while the causal interpretation of co efficients is our primary concern here there is also a sense in which correlations can be interpreted as measuring the known but unobserved parameters of a model imposed on the data and we shall close section iv with a few remarks on this second issue

market organisation and trading relationships in this paper we give a theoretical model of buyers behaviour on a market for a perishable good where no prices are posted we show that if buyers learn from their own previous experience there is a sharp division between those who learn to be loyal to certain sellers and those who continue to shop around this feature remains in more general models which are simulated and is consistent with empirical data from the marseille fish market

was vietnam s economic growth in the 1990s pro poor an analysis of panel data from vietnam abstractinternational aid agencies and almost all economists agree that economic growth is necessary for reducing poverty yet some economists question whether it is sufficient for poverty reduction vietnam enjoyed rapid economic growth in the 1990s but a modest increase in inequality during that decade raises the possibility that the poor in vietnam benefited little from that growth this article examines the extent to which vietnam s economic growth has been pro poor giving particular attention to two issues the first is the appropriate comparison group when comparing the poorest x of the population at two points in time should the poorest x in the first time period be compared to the poorest x in the second time period some of whom were not the poorest x in the first time period or to the same people in the second time period some of whom are no longer among the poorest x the second is measurement error estimates of growth among the poorest x of the population are likely to be biase

the declining price anomaly abstract data from wine auctions indicate that identical products sold sequentially typically follow a decreasing pattern of prices known as the declining price anomaly this is explained for both first and second price auctions by appealing to risk averse bidders earlier bids are then equal to expected later prices plus a risk premium associated with the risky future price we show that this logic rests on the assumption of nondecreasing absolute risk aversion which is necessary for pure strategy equilibrium bidding functions to exist thus decreasing absolute risk aversion implies ex post inefficiency with positive probability data from wine auctions are used to confirm the existence of the declining price anomaly journal of economic literature classification numbers d43 d44 d81 d82 l81

national pro poor spending programmes and their effect on income inequality and poverty evidence from vietnam abstractthis article examines the causal effects of the national pro poor targeted programmes ntps on both poverty incidence and inequality in vietnam over the period 2002 2010 while the links between ntps and poverty alleviation and income inequality have previously been analysed independently this study is the first to offer a comprehensive analysis of ntps expenditure on poverty and inequality simultaneously applying the system generalized method of moments estimator to a panel of vietnamese regional data we are unable to establish that ntps have significantly mitigated poverty incidence however we estimate that ntps have significantly increased inequality we offer possible explanations why the ntps have resulted in these unintended outcomes and discuss potential policies which can reduce both poverty and inequality

estimation of poverty transition matrices with noisy data summary this paper investigates measurement error biases in estimated poverty transition matrices we compare transition matrices based on survey expenditure data to transition matrices based on measurement error free simulated expenditure the simulation model uses estimates that correct for measurement error in expenditure we find that time varying measurement error in expenditure data magnifies economic mobility roughly 45 of households initially in poverty at time t 1 are found to be out of poverty at time t using data from the korean labor and income panel study when measurement error is removed this drops to between 26 and 31 of households initially in poverty copyright 2016 john wiley sons ltd

how auctions work for wine and art interview auctioneers and even to buy a little wine in the meantime i have also had the opportunity with john abowd 1988 to observe and collect data on the auction sale of impressionist and contemporary paintings this paper reports on some of the empirical regularities that i and others have observed in the actual operation of the auction markets for these items in view of the rich and diverse array of theoretical literature on auctions it seems high time economists began to spell out precisely what facts it is meant to explain 2

how much of observed economic mobility is measurement error iv methods to reduce measurement error bias with an application to vietnam research on economic growth and inequality inevitably raise issues concerning economic mobility because the relationship between long run inequality and short run inequality is mediated by income mobility for a given level of short run inequality greater mobility implies lower long run inequality yet empirical measures of both inequality and mobility are biased upward due to measurement error in income and expenditure data collected from household surveys this paper presents a straightforward method to remove this bias using instrumental variable estimates the method is applied to panel data from vietnam the results imply that at least 15 and perhaps as much as 42 of measured mobility is upward bias due to measurement error the results also suggest that measurement error accounts for at least 12 of measured inequality

capital constraints and the performance of entrepreneurial firms in vietnam entrepreneurship has been among the key driving forces of the emergence of a dynamic private sector during the recent decades in vietnam this article addresses for vietnam the questions how capital constraints affect the performance of family firms and how entrepreneurs human and social capital interact with capital constraints to leverage entrepreneurial income a panel of 1721 firms in 4 years is used results are consistent with the resource dependency approach indicating an adverse effect of capital constraints on firm performance firms suffering capital constraints perform substantially better suggesting that they need more capital simply to finance newly recognized profit opportunities human capital plays a vital role in relaxing capital constraints and improves the entrepreneurial performance whereas the effect of social capital stemming from strong ties and weak ties is limited strong ties bring emotional support and weak ties give nonfinancial benefits from regular and useful business contacts advanced econometric analysis tools to take into account the endogeneity of capital constraints are used to establish relationships among relevant variables

price cost margins and imports in an oligopolistic market abstract in a recent letter in this journal urata 1979 found an unexpected positive and significant association between price cost margins and import to domestic shipment ratio for the u s textile and apparel industries in the present letter a theoretical explanation for this phenomenon is presented by extending a conjectural variation oligopoly model

is india s economic growth leaving the poor behind there has been much debate about how much india s poor have shared in the economic growth unleashed by economic reforms in the 1990s the authors argue that india has probably maintained its 1980s rate of poverty reduction in the 1990s however there is considerable diversity in performance across states this holds some important clues for understanding why economic growth has not done more for india s poor india s economic growth in the 1990s has not been occurring in the states where it would have the most impact on poverty nationally if not for the sectoral and geographic imbalance of growth the national rate of growth would have generated a rate of poverty reduction that was double india s historical trend rate states with relatively low levels of initial rural development and human capital development were not well suited to reduce poverty in response to economic growth the study s results are consistent with the view that achieving higher aggregate economic growth is only one element of an effective strategy for poverty reduction in india the sectoral and geographic composition of growth is also important as is the need to redress existing inequalities in human resource development and between rural and urban areas

concentration profitability and trade in a simultaneous equation analysis the case of taiwan this paper is the first attempt to use a simultaneous four equation system to study the role of foreign trade in the analysis of market structure and performance and the determinants of trade intensity in a newly industrializing country taiwan a cross sectional analysis is carried out with the manufacturing censuses of 1976 the results indicate that public enterprises significantly influence market structures and performance also import control measures influence import intensity significantly and offset potential impacts of imports on concentration and on profitability however trade intensity is mainly explained by comparative advantage rather than market forces concentration and profitability

auctions and the price of art the value of most important works of art is established by public auction either directly by an actual sale or indirectly by reference to other sales how the auction system works is thus a critical determinant of how the public s preferences are translated into the evaluation of artistic work the auction system is central in the determination of the incentives for artistic work and the efficiency of the auction system is a key determinant of the cost of creating and distributing works of art this paper contains a review of the burgeoning new research of the last decade that has been designed to shed light on how the art auction system actually works what it indicates about price formation and how well it performs we begin our discussion in section 2 with a short description of the mechanics of the auction system and then organize the remainder of our discussion around two major topics the first topic concerns how auction prices can be used to determine and compare overall price movements within the art market and other markets and the second topic concerns how the auction mechanism influences prices we

market structure and price cost margins in a paper that has become a standard reference in the structure conductperformance approach to industrial economics cowling and waterson 1976 developed a theoretical rationale for expecting industry profitability to be positively correlated with the level of concentration their model based on a simple algebraic description of oligopoly behaviour has been interpreted as providing a justification for the common empirical practice of cross industry regression analysis of price cost margins in terms of concentration levels in the present paper we show that on further examination this model implies a joint determination of margins and concentration this provides some interesting comparative static results of relevance to inter industry differences in concentration levels equally however it leads to various cautionary insights concerning the meaning of price cost margin versus concentration regressions

learning to bid in sequential dutch auctions abstract we propose an agent based computational model to investigate sequential dutch auctions with particular emphasis on markets for perishable goods and we take as an example wholesale fish markets buyers in these markets sell the fish they purchase on a retail market the paper provides an original model of boundedly rational behavior for wholesale buyers behavior incorporating learning to improve profits conjectures as to the bids that will be made and fictitious learning we analyze the dynamics of the aggregate price under different market conditions in order to explain the emergence of market price patterns such as the well known declining price paradox and the empirically observed fact that the very last transactions in the day may be at a higher price the proposed behavioral model provides alternative explanations for market price dynamics to those which depend on standard hypotheses such as diminishing marginal profits furthermore agents learn the option value of having the possibility of bidding in later rounds when confronted with random buyers such as occasional participants or new entrants they learn to bid in the optimal way without being conscious of the strategies of the other buyers when faced with other buyers who are also learning their behavior still displays some of the characteristics learned in the simpler case even though the problem is not analytically tractable

transactions that did not happen and their influence on prices abstract this paper studies data from the wholesale fruit and vegetables market in marseille we have details of counteroffers to the prices that were proposed by the seller even when no transaction took place we analyse the evolution of prices and the relation between the final price struck and the proposals of the two parties periods with no buyer refusals of offers or bargaining with no transaction will lead to a revision of the seller s first price more importantly the sharing of the surplus moves in the buyer s favour during the day these theoretical predictions are confirmed by our data set

profitability concentration imports and exports the case of taiwan s midstream petrochemical industries based on an open economy oligopoly model causalities among domestic firms price cost margin pcm domestic concentration import and export shares are derived and a simultaneous equation system is established by utilizing the 1989 1997 data of taiwan s midstream petrochemical industries three stage least squares is used to estimate the system the empirical results confirm the derived results and demonstrate 1 there exist simultaneous relationships among domestic pcm domestic concentration import and export shares 2 import concentration affects domestic concentration positively but affects domestic pcm import and export shares negatively 3 diversifying international markets improves domestic firms pcm 4 domestic firms seem to be in a situation of collusion

concentration and profitability in a dichotomous economy the case of taiwan this paper is an attempt to apply a two regime and a recursive structure performance analysis to one of the newly industrializing countries taiwan a two regime approach is employed because taiwan s market structure is hypothesized as being dichotomous the export oriented sector being distinct with the domestic oriented sector a recursive system is used because industry concentration is not only a determinant of profitability but is itself determined by other variables

measurement error bias in estimates of income and income growth among the poor analytical results and a correction formula abstract in any population income growth among the poor may be higher or lower than overall income growth estimates of income growth among the poor are almost always based on household surveys but income and expenditure data in those surveys are almost always measured with error this article uses the assumption that income follows a lognormal distribution to demonstrate that such measurement error can lead to biased estimates of the mean income of the poor and the growth of that mean income over time in particular when both income and the measurement error are lognormally distributed i measurement error leads to underestimation of the mean income among the poor at any point in time ii increases decreases in measurement error over time for a given level of inequality lead to underestimation overestimation of income growth among the poor and iii increases decreases in inequality over time for a given level of measurement error lead to overestimation underestimation of income growt

what s that got to do with the price of fish buyers behavior on the ancona fish market abstract in this paper we analyze the ancona wholesale fish market meritan where transactions take place in three simultaneous dutch auctions our objective is to characterize the behavior of market participants and in particular that of buyers in such a market structure our analysis shows that buyer seller relationships are less important than in a pairwise bargaining market such as the marseille fish market but that a significant amount of loyalty is still present under the auction mechanism we provide an explanation of the declining price paradox for the fish market of ancona by linking the rule used by the buyers to set their bid to the relationship between the variation in the price of the last transactions in the day and the quantity of fish available on that day in fact the average price tends to increase for the last transactions on days characterized by a limited supply of fish

exchange rates market structure and price cost margins evidence from a developing country this paper analyses the sensitivity of firm performance to exchange rate fluctuations in a two country world consisting of a developing domestic country and a developed foreign country we show that this sensitivity is closely related with market structure and the share of imported inputs in total cost when the share of imported inputs is low depreciation leads to an increase in price cost margin this increase intensifies in more competitive industries when the imported input share is high the price cost margin may decrease as a result of depreciation and this effect becomes pronounced in more competitive industries the empirical test where we used 3 digit turkish manufacturing industry data support most of the findings of our model

design of discrete dutch auctions with consideration of time abstract as a departure from much of the existing literature that aims at maximizing the expected revenue from a single auction this research work is concerned with the design of discrete dutch auctions to achieve the optimal balance between the selling price of the object and the auction duration so that the auctioneer s expected revenue per unit of time is as high as possible the new objective is especially important in trading perishable products or services when multiple auctions are to be conducted by the auctioneer for different sellers during a limited period of time our findings indicate that the proposed discrete dutch auction models generate higher average revenues per unit of time for the auctioneer than their counterparts without consideration of time this is achieved by reducing the duration of each auction in exchange for more auctions to be held within the given time frame so that the small decrease in the revenues from the longer auctions is more than compensated for by the large increase in the total revenues from the shorter auctions the numerical results show that the proposed discrete dutch auction design becomes extremely useful when the number of bidders becomes large it is also shown that complete knowledge about the number of bidders in the auction results in a higher auctioneer s expected revenue per unit of time

has the development gap between the ethnic minority and majority groups narrowed in vietnam evidence from household surveys using household data for rural northern vietnam between 1993 and 2014 we find that the ethnic minority group continued to lag behind the majority group in various development indicators despite the overall improvement in living standards our regression and decomposition analyses show that the structural differences between the two groups are an important cause of persistent development gap however the nature of structural differences changed over time and no single source of structural difference explains the persistent gap we argue that more minority appropriate policies are needed to lift poor minority households out of poverty further and reduce the development gap

the declining price anomaly in dutch dutch rose auctions in symmetric independent private value auctions of a single object with risk neutral bidders the english second price auction has strategic simplicity it is optimal for bidders to reveal their valuation of the object and make bids accordingly in that case the auction is won by the person with the highest valuation who pays a price equal to the second highest valuation in a dutch first price auction this simplicity vanishes here winning bidders have to pay their bid to make a profit they shade their bids and bid below their valuation of the object somewhat loosely one may state that an english auction is truth revealing whereas a dutch auction requires strategic behavior the simple structure of the one unit english auction vanishes if two identical objects are auctioned sequentially now in the first round it is optimal for bidders to shade their bids to account for the option value of participating in the subsequent second round robert j weber 1983 bidders with a higher valuation also have a higher option value therefore they shade their bids in the first round by a greater amount than do bidders with a lower valuation as the auction proceeds the number of bidders decreases over the sequence of auctions the number of objects decreases as well the first fact has a negative effect on the competition for an object and the second has a positive effect both effects cancel out and prices follow a martingale as a result all gains to waiting are arbitraged away and the expected prices in both rounds are the same the latter result also holds for sequential auctions of more than two objects and does not depend on whether the auction is english or dutch this neat theoretical result is not supported by empirical research which usually finds price declines orley ashenfelter 1989 found a mild price decrease in sequential auctions of identical units of wine mcafee and daniel vincent 1993 also present empirical evidence on sequential wine auctions they found that on average the second unit of wine was sold at a price 1 4 percent lower than the price of the first unit victor ginsburgh 1998 uses data from wine auctions in which the auctioneer acted as an agent for bidders who were not present at the auction he found price declines but apparently the absent bidders entered bids that did not fit with the theory empirical studies by ashenfelter and david genesove 1992 see also jean jacques laffont 1997 and alan beggs and kathryn graddy 1997 concern heterogeneous objects they also detected price declines because of the contradiction between theory and empirical studies the declining price phenomenon is regarded to be an anomaly

simultaneous equations models of the structure performance paradigm abstract this paper is concerned with determining the dimension of the simultaneous equations model surrounding the basic profits concentration relationship a very general model is considered and then simplified using a simple test for exogeneity and it is concluded that the model is nonlinear in concentration and that simultaneous interaction occurs between profits and foreign competition variables

on the specification of structure performance relationships this paper argues that most estimated structure profitability equations in industrial economics have not been derived from a single coherent view of the behaviour of firms the independent variables in such equations have often been derived on the basis of a literature search and by appeal to conflicting approaches e g constrained and unconstrained profit maximisation the use of a coherent approach indicates that structure performance equations are likely to be highly non linear and that simultaneous equation estimation is neither required nor appropriate in some cases single equation estimation is adequate and in other cases reduced form equations are needed

measurement error and earnings dynamics some estimates from the psid validation study previous empirical work on measurement error in survey earnings data has shown that the variance of the measurement error is roughly constant over time it is negatively correlated with true earnings and it is autocorrelated with previous measurement errors this article proposes a simple model in which the measurement error stems from underreporting of transitory earnings fluctuations and a white noise component the model fits well to data from the panel study of income dynamics validation study the results imply that autocorrelations in the changes of earnings can be estimated relatively accurately despite the presence of measurement error
