menu dependent stochastic feasibility we examine the role of stochastic feasibility in consumer choice using a random conditional choice set rule rccsr and uniquely characterize the model from conditions on stochastic choice data feasibility is modeled to permit correlation in availability of alternatives this provides a natural way to examine substitutability complementarity we show that an rccsr generalizes the random consideration set rule of manzini and mariotti 2014 we then relate this model to existing literature in particular an rccsr is not a random utility model

the balance of power in rural marketing networks a case study of snake trading in cambodia abstract producers in small scale rural markets often receive unfavourable prices for their goods as a result of more powerful market participants this study uses a combination of price analysis and interview data to assess the position of snake hunters in the aquatic snake market from tonle sap lake in cambodia despite the hunters dependence on intermediary traders for market access and credit the evidence implies that they are not powerless participants intermediary traders operate under high competition as a result of the increasing scarcity of snakes and therefore despite interlocked credit and snake markets offer relatively high prices to hunters

single crossing random utility models we propose a novel model of stochastic choice the single crossing random utility model scrum this is a random utility model in which the collection of preferences satisfies the single crossing property we offer a characterization of scrums based on two easy to check properties the classic monotonicity property and a novel condition centrality the identified collection of preferences and associated probabilities is unique we show that scrums nest both single peaked and single dipped random utility models and establish a stochastic monotone comparative result for the case of scrums

lottery choice incentives complexity and decision time this paper reports the results of an experiment on lottery choice in which decision cost is measured as decision making time a simple decision cost model motivates this measurement and the experiment and predicts relationships between incentive mechanism manipulations and decision making time which are borne out in the experiment the decision cost model also suggests that decisions will change in the face of the incentive manipulations in the experiment this suggestion is borne out in a complex decision making environment but not in a simple one specification tests demonstrate that observed changes in subjects behavior are not merely due to changes in subject specific error variance one may conclude from this that the payoff dominance problem is a real issue in complex decision making experiments copyright 1993 by royal economic society

rationally inattentive seller sales and discrete pricing prices tend to remain constant for a period of time and then jump in the literature this rigidity is usually interpreted to reflect a cost of adjusting prices this article shows that price rigidity can alternatively reflect optimal price setting when there are no adjustment costs namely if the seller is rationally inattentive the model generates non trivial pricing patterns that are consistent with the data and that are hard to explain with the traditional adjustment cost model in particular prices are adjusted frequently but move back and forth between a few given values hazard functions are downward sloping and responses to persistent shocks are sluggish these results are obtained in a model that implements rational inattention without simplifying assumptions on the functional forms of the processed signals

unexpected inflation and bank stock returns the case of france 1977 1991 abstract this paper evaluates the impact of unexpected inflation on the stock returns of a sample of french banks it offers an empirical test of theories that have predicted an impact of inflation on the stock returns of banks the paper complements a large literature that has focused exclusively on the impact of unexpected interest rates the analysis provides empirical support to the hypothesis that in periods of volatile inflation there exists an inflation risk factor which is independent of the well documented interest rate factor

how do banks respond to shocks a dynamic model of deposit taking institutions abstract this paper proposes a dynamic model of the optimal choices of a bank that benefits from market power and takes into account the impact of the deposit generation process interbank lending borrowing emerges as a buffer that assists the bank in smoothing intertemporal adjustments in interdependent loan and deposit choices the bank smooths the impact of interest rates shocks on its customers to minimize the adjustments over time of the stocks of deposits and loans it does not however provide insurance against negative shocks of real origin that increase its expected default costs the predictions of the model help to shed light on the available empirical evidence and to analyze some recent developments of the banking industry

discrete actions in information constrained decision problems individuals are constantly processing external information and translating it into actions this draws on limited resources of attention and requires economizing on attention devoted to signals related to economic behaviour a natural measure of such costs is based on shannon s channel capacity modelling economic agents as constrained by shannon capacity as they process freely available information turns out to imply that discretely distributed actions and thus actions that persist across repetitions of the same decision problem are very likely to emerge in settings that without information costs would imply continuously distributed behaviour we show how these results apply to the behaviour of an investor choosing portfolio allocations as well as to some mathematically simpler tracking problems that illustrate the mechanism trying to use costs of adjustment to explain stickiness of actions when interpreting the behaviour in our economic examples would lead to mistaken conclusions

rational inattention optimal consideration sets and stochastic choice we unite two basic approaches to modelling limited attention in choice by showing that the rational inattention model implies the formation of consideration sets only a subset of the available alternatives will be considered for choice we provide necessary and sufficient conditions for rationally inattentive behaviour which allow the identification of consideration sets in simple settings chosen options are those that are best on a stand alone basis in richer settings the consideration set can only be identified holistically in addition to payoffs prior beliefs impact consideration sets linear inequalities identify all priors consistent with each possible consideration set

testing models of consumer search using data on web browsing and purchasing behavior using a large data set on web browsing and purchasing behavior we test to what extent consumers are searching in accordance to various classical search models we nd that the benchmark model of sequential search with a known distributions of prices can be rejected based on the recall patterns we observe in the data moreover we show that even if consumers are initially unaware of the price distribution and have to learn the price distribution observed search behavior for given consumers over time is more consistent with non sequential search than sequential search with learning our

the rise fall and rise again of industrial location theory m ccann p and sheppard s 2003 the rise fall and rise again of industrial location theory reg studies 37 649 663 in this paper we will argue that new academic fashions new international institutional arrangements new communications technology and new developments in data availability have all renewed the need for a redevelopment of analytical industrial location theory our paper will argue that the microeconomic foundations of industrial location theory must now be reconsidered in particular the methodological basis of traditional industrial location models needs to be reconciled with recent models of clustering the new economic geography literature and also more aggregate systemic levels of analysis we will argue that in order to do this it is necessary first to specify the transactions cost assumptions underlying these various approaches second to adopt broader definitions of spatial transactions costs and third to incorporate environmental characteristics within an orthodox loca

a note on the temporal variability of canadian financial services stock returns abstract we show that financial services stock returns in canada are covariance nonstationary with respect to any benchmark variable and vary negatively with interest rate levels we find that the conditional correlation between financial services stock returns and the market returns varies directly and monotonically with market volatility this result is robust to monetary regime shifts and other sources of high volatility these findings combined with those of kane and unal 1988 for the u s cast considerable doubt on the constant coefficient two index model and its variants to provide reliable estimates of usual risk measures

interest rate and exchange rate exposures of banking institutions in pre crisis korea this study empirically investigates interest rate and exchange rate exposures of banking institutions in pre crisis korea using the sensitivity of stock returns as a measure of the exposure it is shown that korean commercial banks and merchant banking corporations had been significantly exposed to both interest rate and exchange rate risks and that the subsequent profitability of commercial banks was significantly associated with the degree of pre crisis exposure the evidence suggests that along with the negative exposure of banking institutions the sharp depreciation of the korean won and high interest rates at the end of 1997 further deteriorated the banking sector s capital adequacy worsening the financial crisis the korean case highlights the importance of upgrading financial supervision and risk management practices as a precondition for successful financial liberalization

limited information and advertising in the u s personal computer industry traditional discrete choice models assume buyers are aware of all products for sale in markets where products change rapidly the full information assumption is untenable i present a discrete choice model of limited consumer information where advertising influences the set of products from which consumers choose to purchase i apply the model to the u s personal computer market where top firms spend over 2 billion annually on advertising i find estimated markups of 19 over production costs where top firms advertise more than average and earn higher than average markups high markups are explained to a large extent by informational asymmetries across consumers where full information models predict markups of one fourth the magnitude i find that estimated product demand curves are biased toward being too elastic under traditional models i show how to use data on media exposure to improve estimated price elasticities in the absence of micro ad data

rational inattention and migration decisions abstract acquiring information about destinations can be costly for migrants we model information frictions in the rational inattention framework and obtain a closed form expression for a migration gravity equation that we bring to the data the model predicts that flows from countries with a higher cost of information or stronger priors are less responsive to variations in economic conditions in the various destinations as migrants rationally get less information before deciding where to move the econometric analysis reveals systematic heterogeneity in the pro cyclical behavior of migration flows across origins that is consistent with the existence of information frictions

delegation of investment decisions and optimal remuneration of agents abstract we analyze an investor who delegates information acquisition and investment decisions to an agent the investor cannot monitor the agent s effort or information optimal pay schemes contain bonuses that increase with the net return rate of the investment but unlike conventional contracts at a decreasing rate moreover investments with low return rates are penalized again unlike conventional contracts nevertheless it may be optimal for the investor to reward the agent above the agent s reservation utility we examine the role of the agent s risk attitude for the shape of the pay scheme and whether firing after bad investments is a more effective threat than reduced pay we also analyze how the nature of the contract changes if the agent is given bargaining power

thrift stock returns and portfolio interest rate sensitivity abstract in practice the interest rate sensitivity of depository institution di net worth is measured in terms of maturity mismatches arising from nominal contracts in their financial portfolios academic studies also frequently invoke nominal contracting to explain a positive covariation observed between di stock returns and bond returns for a sample of thrifts reporting detailed financial data 1984 1992 this study estimates monthly changes in their financial portfolio values due to changes in interest rates these portfolio value changes are found to be unimportant in explaining the thrifts stock returns and are unable to account for a positive covariation between the stock returns and bond market returns potential weaknesses in the tests seem inadequate to explain the results explanations other than nominal contracting may warrant more consideration in relating dis net worth to interest rate changes

rethinking the economics of location and agglomeration fundamental problems exist with the classical characterisation of agglomeration economies since such definitions do not reflect the various cost issues on which firms may wish to economise a lack of understanding of the relationship between the notions of market hierarchies and locational behaviour leads to confusion not only in applied economic interpretation but more fundamentally in the construction of theoretical location models in particular neo classical location theory can be shown to be crucially flawed as a basis for spatial analysis this paper therefore attempts to provide an alternative definition of the various types of agglomeration economies such that the various strands of economic theory might be used in a more rigorous manner in the discussion of spatial increasing returns

decision time consideration time and status quo bias economists increasingly appreciate the value of studying the time taken to make decisions in order to provide insights into decision makers choices this article shows that studying how time is allocated among individual options is also valuable in helping researchers to understand the impact default options have on decision makers attention allocation as approximated by how the time is allocated the study of this impact generates new insights into the well known choice phenomenon of status quo bias which typically refers to decision makers tendency to stick to a default option by designing a series of novel experiments i find that this bias arises even when the choice is among prizes of fixed monetary value expressed in arithmetic form i also find asymmetric attention i e more time devoted to default options and strikingly asymmetric choice errors specifically decision makers fail to select an alternative better than the default 28 of the time while they incorrectly select an alternative worse than the default only 11 of the time and provide evidence supporting a causal relationship between asymmetric attention and asymmetric errors jel d03 d12 d83

costly information acquisition experimental analysis of a boundedly rational model the directed cognition model assumes that agents use partially myopic option value calculations to select their next cognitive operation the current paper tests this model by studying information acquisition in two experiments in the first experiment information acquisition has an explicit financial cost in the second experiment information acquisition is costly because time is scarce the directed cognition model successfully predicts aggregate information acquisition patterns in these experiments when the directed cognition model and the fully rational model make demonstrably different predictions the directed cognition model better matches the laboratory evidence jel d83

innovations in interest rates duration transformation and bank stock returns this paper studies the cross sectional variation in the sensitivity of bank stock returns to interest rate innovations an econometric framework is developed to estimate the mismatch between asset and liability durations the innovation sensitivity is then related to duration transformation the results indicate that banks are exposed to interest rate risk and that the innovation sensitivity is positively related to duration transformation copyright 1992 by ohio state university press

information immobility and the home bias puzzle many argue that home bias arises because home investors can predict home asset payoffs more accurately than foreigners can but why does global information access not eliminate this asymmetry we model investors endowed with a small home information advantage who choose what information to learn before they invest surprisingly even when home investors can learn what foreigners know they choose not to investors profit more from knowing information others do not know learning amplifies information asymmetry the model matches patterns of local and industry bias foreign investments portfolio outperformance and asset prices finally we propose new avenues for empirical research

zipf s law for cities an explanation zipf s law is a very tight constraint on the class of admissible models of local growth it says that for most countries the size distribution of cities strikingly fits a power law the number of cities with populations greater than s is proportional to 1 s suppose that at least in the upper tail all cities follow some proportional growth process this appears to be verified empirically this automatically leads their distribution to converge to zipf s law

interest rate uncertainty and the financial intermediary s choice of exposure the financial intermediary s choice of operating as a broker with minimal risk exposure or as an asset transformer with interest rate risk is modeled as a funds inventory decision made prior to the resolution of uncertainty regarding the borrowing or lending interest rates it is shown that an increase in the interest rate uncertainty leads the intermediary to reduce its exposure thereby offering decreased asset transformation and more brokerage services however a stochastic increase in the interest rates leads to greater asset transformation and less brokerage services the high and volatile nominal interest rates associated with contemporary inflation have prompted a pronounced change in commercial bank balance sheets low cost deposits have been replaced by alternative funding vehicles bearing high and increasingly variable interest rates see budzeika 3 4 kane 9 and silber 13 in an apparent adaptive response to the loss of deposits banks have eschewed fixed rate loans in favor of variable rate lending thereby more closely matching the durations of their assets and liabilities see flannery 6 and boltz and campbell 2 this change in bank lending practices has been popularly interpreted as an effort to immunize cash flows in the face of increased interest rate uncertainty see haley 8 and wojnilower 15 however apart from niehans and hewson 11 the adaptive recomposition of bank balance sheets has not been formally addressed in this paper we provide a model of balance sheet duration mismatching and then show that an increase in interest rate volatility is likely to lead an intermediary to choose a balance sheet that is more closely matched 1 balance sheet mismatching can be understood in terms of the two basic functions of financial intermediaries as explained by niehans 10 brokerage and asset transformation if a financial intermediary precisely matches the properties of its assets and liabilities and thereby maintains a perfectly hedged position it functions exclusively as a broker joining borrowers and lenders without assuming any risk the broker s function is then simply to reduce the search costs associated with joining complementary transactors the brokerage function is deshmukh is professor of managerial economics and decision sciences greenbaum is harold l stuart professor of banking and finance and kanatas is assistant professor of finance all at northwestern university s j l kellogg graduate school of management we gratefully acknowledge the helpful suggestions of michael brennan and an anonymous referee this project was supported by the banking research center and the kellogg center for advanced study in managerial economics and decision sciences

exclusive dealing as a barrier to entry evidence from automobiles exclusive dealing contracts between manufacturers and retailers force new entrants to set up their own costly dealer networks to enter the market we ask whether such contracts may act as an entry barrier and provide an empirical analysis of the european car market we first estimate a demand model with product and spatial differentiation and quantify consumers valuations for dealer proximity and dealer exclusivity we then perform policy counterfactuals to assess the profit incentives and possible entry deterring effects of exclusive dealing we find that there are no unilateral incentives to maintain exclusive dealing but there is a collective incentive for the industry as a whole furthermore a ban on exclusive dealing would raise the smaller entrants market share but more importantly consumers would gain not so much because of increased price competition but rather because of the increased spatial availability which compensates for the demand inefficiency from a loss of dealer exclusivity

rational choice with status quo bias abstract motivated by the empirical findings concerning the importance of one s current situation on her choice behavior the main objective of this paper is to propose a rational choice theory that allows for the presence of a status quo bias and that incorporates the standard choice theory as a special case we follow a revealed preference approach and obtain two nested models of rational choice that allow phenomena like the status quo bias and the endowment effect and that are applicable in any choice situation to which the standard static choice model applies

some empirical tests of the theory of arbitrage pricing we estimate the parameters of ross s arbitrage pricing theory apt using daily return data during the 1963 78 period we compare the evidence on the apt and the capital asset pricing model capm as implemented by market indices and find that the apt performs well the theory is further supported in that estimated expected returns depend on estimated factor loadings and variables such as own variance and firm size do not contribute additional explanatory power to that of the factor loadings

competing for consumer inattention consumers purchase multiple types of goods but may be able to examine only a limited number of markets for the best price we propose a simple model that captures these features conveying new insights a firm s price can deflect or draw attention to its market and consequently limited attention introduces a new dimension of cross market competition we characterize the equilibrium and show that having partially attentive consumers improves consumer welfare with less attention consumers are more likely to miss the best offers but enhanced cross market competition decreases average price paid as leading firms try to stay under the consumers radar

just in time inventory control and the economic integration of japanese owned manufacturing plants with the county state and national economies of the united states reid n 1995 just in time inventory control and the economic integration of japanese owned manufacturing plants with the county state and national economies of the united states reg studies 29 345 355 this paper attempts to shed light on the ongoing debate concerning the spatial implications of just in time jit manufacturing systems the central issue around which this debate has focused concerns the extent to which use of jit inventory control encourages the spatial clustering of the members of a jit network this paper tests the hypothesis that plants which use jit inventory control purchase a greater proportion of their material inputs from inside their host economy than plants which do not use jit inventory control using survey data collected from 239 us based japanese owned manufacturing plants this hypothesis is tested for host economies defined at three geographic scales county state and national support for the hypothesis is found at the county but not at the state and national scales

consideration sets and competitive marketing we present a model of competitive marketing based on the notion that consumers are boundedly rational and that firms use marketing tactics in an attempt to influence consumers decision process the standard model of consumer behaviour assumes that the consumer applies well defined preferences to a perfectly perceived set of available alternatives we retain the assumption that consumers have stable preferences but relax the assumption that they have a perfect perception of what is relevant for their consumption problem thus allowing firms to manipulate that perception our aim is to explore the market implications of this departure from the standard model especially for the way firms deploy marketing strategies in competitive environments the cornerstone of our model is the observation that in the modern marketplace consumers face an overwhelmingly large variety of products and therefore often use screening criteria deliberate as well as unconscious in order to reduce the number of relevant alternatives as a result consumers apply their preferences not to the set of objectively feasible alternatives but to a potentially smaller set which they construct at an earlier stage of the decision process borrowing a term from the marketing literature we refer to this set as the consideration set the basic idea underlying this term is that consumers may be unaware of some of the feasible products and even when they become aware of a new product they still need to be persuaded to consider it as a potential substitute to their currently consumed product

industrial alliances and firm location behaviour some evidence from the us semiconductor industry this study uses a log linear model in order to analyse data on interfirm strategic alliances within the us semiconductor industry the findings suggest that although the finding that the intensity of information transaction between firms is directly associated with geographical proximity this effect is much less localized than would be usually expected the results cast doubt on much of the existing qualitative literature on the nature of agglomeration externalities

observational equivalence regional studies and regional science mccann p 2007 observational equivalence regional studies and regional science regional studies 41 1209 1221 this paper considers the methodological and empirical issues raised by the adoption of stylized constructs in the development of regional policy public policies invariably require funding and the greater levels of public data availability and press scrutiny nowadays have led to increasing requirements for policy transparency driven by evidence based policy design implementation monitoring and evaluation at the same time however many current urban and regional policy frameworks are increasingly being based on constructs that do not lend themselves to empirical evaluation therefore there appears to be something of a mismatch this paper discusses these problems and argues that instead of being seen as contradictory one can regard certain aspects of regional analysis as raising topical questions and issues to be examined while other methodological approaches are always required in ord

free to choose reform choice and consideration sets in the english national health service choice in public services is controversial we exploit a reform in the english national health service to assess the effect of removing constraints on patient choice we estimate a demand model that explicitly captures the removal of the choice constraints imposed on patients we find that post removal patients became more responsive to clinical quality this led to a modest reduction in mortality and a substantial increase in patient welfare the elasticity of demand faced by hospitals increased substantially post reform and we find evidence that hospitals responded to the enhanced incentives by improving quality this suggests greater choice can raise quality

heuristic thinking and limited attention in the car market can heuristic information processing affect important product markets analyzing over 22 million wholesale used car transactions we find evidence of left digit bias in the processing of odometer values whereby individuals focus on the number s leftmost digits the bias leads to discontinuous drops in sale prices at 10 000 mile odometer thresholds along with smaller drops at 1 000 mile thresholds these findings reveal that information processing heuristics matter even in markets with large stakes and easily observed information we model left digit bias in an inattention framework and structurally estimate the inattention parameter empirical patterns suggest the results are driven by final customers rather than professional agents jel d12 d44 d83 l81

the price consideration model of brand choice the workhorse brand choice models in marketing are the multinomial logit mnl and nested multinomial logit nmnl these models place strong restrictions on how brand share and purchase incidence price elasticities are related in this paper we propose a new model of brand choice the price consideration pc model that allows more flexibility in this relationship in the pc model consumers do not observe prices in each period every week a consumer decides whether to consider a category only then does he she look at prices and decide whether and what to buy using scanner data we show the pc model fits much better than mnl or nmnl simulations reveal the reason the pc model provides a vastly superior fit to inter purchase spells

market interest rates and commercial bank profitability an empirical investigation the widespread notion that commercial banks borrow short and lend long implies that sharp market interest rate increases may induce a significant number of banking failures this paper develops a method for estimating average asset and liability maturities for a sample of large money center banks regression models are tested to determine if market rate fluctuations have a significant impact on bank profitability the conclusion is negative large banks have effectively hedged themselves against market rate risk by assembling asset and liability portfolios with similar average maturities the impact of market interest rates on commercial bank revenues costs and profitability has increasingly concerned economists and policymakers as financial market conditions have become more volatile in recent years the widespread notion that depository intermediaries borrow short and lend long implies that rapid market rate increases may induce an unacceptable number of financial firm failures monetary policy discussions have reflected this concern for many years the federal reserve board considered stable market rates a goal or at least an intermediate target of monetary policy the extent to which money market conditions are permitted to fluctuate in the short run is also affected by the unique role of the federal reserve system as the nation s lender of last resort liquidity pressures ultimately devolve on the money market and the federal reserve has a responsibility for maintaining orderly conditions in that market

optimal sticky prices under rational inattention this paper presents a model in which price setting firms decide what to pay attention to subject to a constraint on information flow when idiosyncratic conditions are more variable or more important than aggregate conditions firms pay more attention to idiosyncratic conditions than to aggregate conditions when we calibrate the model to match the large average absolute size of price changes observed in micro data prices react fast and by large amounts to idiosyncratic shocks but only slowly and by small amounts to nominal shocks nominal shocks have strong and persistent real effects we use the model to investigate how the optimal allocation of attention and the dynamics of prices depend on the firms environment jel e 3 e5 d8

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

strategic pricing with rational inattention to quality this paper studies both theoretically and experimentally the pricing strategy of a rm that faces a consumer who is rationally inattentive to product quality sims 2003 in a standard sequential pricing game rational inattention to quality produces two types of mixed strategy perfect bayesian equilibria one where sellers pool at a low price and buyers are fully inattentive to quality and one where there is semi pooling at a high price and buyers are selectively attentive to quality i characterize these

search and satisficing many everyday decisions are made without full examination of all available options and as a result the best available option may be missed we develop a search theoretic choice experiment to study the impact of incomplete consideration on the quality of choices we find that many decisions can be understood using the satisficing model of herbert simon 1955 most subjects search sequentially stopping when a satisficing level of reservation utility is realized we find that reservation utilities and search order respond systematically to changes in the decision making environment jel d03 d12 d83
