designing supply contracts contract type and information asymmetry this paper studies the value to a supplier of obtaining better information about a buyer s cost structure and of being able to offer more general contracts we use the bilateral monopoly setting to analyze six scenarios three increasingly general contracts wholesale pricing schemes two part linear schemes and twopart nonlinear schemes each under full and incomplete information about the buyer s cost structure we allow both sides to refuse to trade by explicitly including reservation profit levels for both for the supplier this is implemented through a cutoff policy we derive the supplier s optimal contracts and profits for all six scenarios and examine the value of information and of more general contracts our key findings are as follows first the value of information is higher under two part contracts second the value of offering two part contracts is higher under full information and third the proportion of buyers the supplier will choose to exclude can be substantial

implicit understandings in channels of distribution formal agreements can be used to achieve coordination among channel members these agreements work by exerting explicit control over the members who make the agreements however implicit understandings can be used as a partial substitute for more formal agreements in this paper we show that implicit understandings can develop as channel members learn about each other s behavior we show that this learning leads to the use of the implicit influence each channel member has over the other s behavior the learning leading to an implicit understanding requires some form of experimentation or historical observation this learning results in an oscillating retail price when only one channel member learns the other s behavior both channel members obtain greater profits than when neither member learns and both channel members obtain less profits than when both members learn however the member who does not learn obtains more profits than the member who learns we also show that implicit understandings r

pricing and the news vendor problem a review with extensions in the newsvendor problem a decision maker facing random demand for a perishable product decides how much of it to stock for a single selling period this simple problem with its intuitively appealing solution is a crucial building block of stochastic inventory theory which comprises a vast literature focusing on operational efficiency typically in this literature market parameters such as demand and selling price are exogenous however incorporating these factors into the mode l can provide an excellent vehicle for examining how operational problems interact with marketing issues to influence decision making at the firm level in this paper we examine an extension of the newsvendor problem in which stocking quantity and selling price are set simultaneously we provide a comprehensive review that synthesizes existing results for the single period problem and develop additional results to enrich the existing knowledge base we also review and develop insight into a dynamic inventory extension of this problem and motivate the applicability of such models

the implications of competition among jurisdictions does tiebout need politics the paper investigates whether compensation among local jurisdiction is by itself sufficient to ensure efficient provision of local public goods jurisdictions have fixed boundaries and each has an entrenched government with the power to tax and supply the public good residents can move costlessly among jurisdictions it is shown that competition among numerous jurisdictions is not sificient to guarantee public sector efficiency though residents can vote with their feet land is immobile hence governments can unsurp some land rents for their own ends increasing the number of jurisdictions limits but cannot completely eliminate the ability to exercise discretionary governmental power

money politics and the post war business cycle abstract the political economy literature has enshrined as stylized fact the view that lower inflation and temporarily lower growth follow the election of republican presidents and has emphasized political manipulation of monetary policy as an explanation support for the monetary explanation comes in econometric work that largely ignores identification issues that dominate the literature on measuring the effects of monetary policy we generalize a standard vector autoregression framework to accommodate discrete political party variables we find almost no support for the view that political effects on the macroeconomy operate through monetary policy and only weak evidence that political effects are significant at all

managing channel profits a channel of distribution consists of different channel members each having his own decision variables however each channel member s decisions do affect the other channel members profits and as a consequence actions a lack of coordination of these decisions can lead to undesirable consequences for example in the simple manufacturer retailer consumer channel uncoordinated and independent channel members decisions over margins result in a higher price paid by the consumer than if those decisions were coordinated in addition the ensuing suboptimal volume leads to lower profits for both the manufacturer and the retailer this paper explores the problems inherent in channel coordination we address the following questions what is the effect of channel coordination what causes a lack of coordination in the channel how difficult is it to achieve channel coordination what mechanisms exist which can achieve channel coordination what are the strengths and weaknesses of these mechanism what is the role of nonprice variables e g manufacturer advertising retailer shelf space in coordination does the lack of coordination affect normative implications from in store experimentation can quantity discounts be a coordination mechanism are some marketing practices actually disguised quantity discounts we review the literature and present a simple formulation illustrating the roots of the coordination problem we then derive the form of the quantity discount schedule that results in optimum channel profits this article was originally published in marketing science volume 2 issue 3 pages 239 272 in 1983

migration and income redistribution responsibilities this study examines whether afdc benefits determine or discourage state to state migration flows in the united states a pooled cross section time series model is developed to estimate afdc benefits in a state and recipients and whether benefits in one state affect benefits in other states a second model using data from the 1980 census and the panel study of income dynamics estimates migration of afdc recipients and the level of benefits in in migration and out migration states both models indicate that small but statistically significant amounts of migration occur which may be quite important but only in the long run movers although small in number are much more likely to move to a state with higher benefits states perceive this migration as important indicating that states should have less control and the federal government more control over income redistribution

credibility and policy convergence in a two party system with rational voters the traditional approach to modeling political parties behavior based upon the contribution of anthony downs 1957 assumes that the parties unique objective is to win elections thus they maximize their popularity the crucial implication of this assumption for a two party system is that if the two parties have the same information about voters preferences full convergence of policies results from electoral competition this is the crucial implication of the median voter theorem more generally it may be argued that different parties are motivated differently because they represent different constituencies parties may not care only about winning elections per se but also about the quality of the policies resulting from an election in this case the candidates of the two parties view winning an election not only as a goal per se but also as a means of implementing a better policy for their respective constituencies this paper shows that electoral competitions imply dynamic inconsistency if the voters are modeled as rational and forwardlooking agents and parties do not care exclusively about being elected but also about which policy to implement once elected the dynamic inconsistency arises as follows the parties have an incentive to announce convergent platforms to increase their chances of election however if the elected party is not committed to its electoral platform it has an incentive to follow its most preferred policy rather than the policy announced in its platform if voters are rational they account for this incentive thus in general in a one shot electoral game the only timeconsistent equilibrium is one in which no convergence is possible the two parties follow their most preferred policies and the voters rationally expect this outcome full convergence of parties platforms results only as a limiting case when the parties are completely indifferent with respect to the quality of the policies resulting from the election thus these results differ from the existing literature on ideologically motivated politicians for instance donald wittman 1977 1983 randall calvert 1985 which implicitly assumes the possibility of binding commitments to electoral platforms complete or partial policy convergence can be the outcome of political competition if the interaction between the parties and the voters is modeled as an infinitely repeated game in fact if the candidates have concave objective functions the welfare maximizing policy rule implies a complete convergence of parties policies however this cooperative and agreed upon policy may or may not be sustainable as a subgame perfect equilibrium depending on parameter values in particular it depends on the discount rates of the two parties the degree of polarization of their preferences and the relative popu graduate school of industrial administration carnegie mellon university pittsburgh pa 15213 and national bureau of economic research cambridge ma 02138 this paper is based upon a chapter of my unpublished doctoral dissertation at harvard university i am greatly indebted to jeffrey sachs for directing my attention toward these issues and for many conversations i also wish to thank andrew abel dilip abreu olivier blanchard ramon caminal andrew caplin alex cukierman morris fiorina benjamin friedman herschel grossman howard rosenthal and the referees for very useful comments the responsibilitv af anv n mtnkieis af calrirp nfnlv mine the result of policy convergence in a two party system is more general than the median voter theorem for discussions of convergence results not at the median see john ledyard 1984 peter coughlin 1984 coughlin and shmuel nitzan 1981 melvin hinich 1977 for earlier work on spatial competition see richard mckelvey 1975 hinich ledyard and peter ordeshook 1972 1973 and the references quoted therein the present paper focuses on the result of convergence rather than on the median voter theorem per se

does electoral accountability affect economic policy choices evidence from gubernatorial term limits this paper analyzes the behavior of u s governors from 1950 to 1986 to investigate a reputation building model of political behavior we argue that differences in the behavior of governors who face a binding term limit and those who are able to run again provides a source of variation in discount rates that can be used to test a political agency model we find evidence that taxes spending and other policy instruments respond to a binding term limit if a democrat is in office the result is a fiscal cycle in term limit states which lowers state income when the term limit binds

some empirical evidence on the production level and production cost smoothing models of inventory investment the production smoothing model of inventories has long been the basic paradigm within which empirical research on inventories has been conducted the basic hypothesis embedded in this model is that inventories of finished goods serve primarily to smooth production levels in the face of fluctuating demand and convex cost functions however once we allow for shocks to technology and the costs of producing output firms will also use inventories to shift production from periods in which production costs are relatively high to periods in which production costs are relatively low in this sense inventories can serve to smooth production costs rather production levels in this paper we examine the empirical plausibility of the production level and production cost smoothing models of inventories our basic strategy is to derive and contrast a set of unconditional moment restrictions implied by these models in a way that minimizes the role of auxiliary assumptions regarding market structure and industry demand we find overwhelming evidence against the production level smoothing model and very little evidence against the production cost smoothing mode1 we conclude that the variance of production exceeds the variance of sales in most manufacturing industries because the production cost smoothing role of inventories is quantitatively more important than the production level smoothing role of inventories this abstract was borrowed from another version of this item

do parties matter for economic outcomes a regression discontinuity approach a long standing issue in political economics is to what extent party control makes a difference in determining fiscal and economics policies this question is very difficult to answer empirically because parties are not randomly selected to govern political entities this article uses a regression discontinuity design namely party control changes discontinuously at 50 of the vote share which can produce near experimental causal estimates of the effect of party control on economic outcomes the method is applied to a large panel data set from swedish local governments with a number of attractive features the results show that there is an economically significant party effect left wing governments spend and tax 2 3 more than right wing governments left wing governments also have 7 lower unemployment rates which is partly due to that left wing governments employ 4 more workers than right wing governments jel c21 d72 d78 h71 h72

behaviour preferences and cities urban theory and urban resurgence summary the resurgence of big old cities and their regions is real but it is merely a part of a broader pattern of urban change in the developed countries whose broadest tendency is urban emergence including suburbanisation and movements of population to certain sunbelt regions the problem is that it is difficult to accommodate explanation of both resurgence and emergence using the main explanations in the field today these include theories of the knowledge or creative economy urban amenities diversity and tolerance and urban beauty in most of their common specifications they do well for either resurgent or emergent cities but not for both at the same time this suggests that these ideas interesting as they are require much greater specification and in some cases overhaul in order to offer satisfactory responses to the diversity of patterns of urban growth by examining some of these deficiencies we conclude that urban theory needs a better understanding of urban choice behaviours and especially the effects of bundling the limits to preference substitutions and the relationship between past and present preferences in order to become fully effective in explaining urban resurgence and urban emergence when these aspects of choice and preference are better integrated into urban theory then the exogenous causes of urbanisation can be made more endogenous and in addition they can be applied better to both emergence and resurgence urban research can by so doing also potentially become more policy relevant

a comparison of two sourcing tactics for a new component abstract we compare two sourcing tactics for a manufacturer to purchase a new component to be used in a one time production run of a new product with uncertain and price elastic demand one alternative is to issue a request for quote rfq which is where the manufacturer requests a price quantity schedule from suppliers the manufacturer uses this information to determine a production quantity and the number of components to purchase from each supplier the other alternative is to post a bid specifying how the manufacturer s purchase quantity will depend on the supplier s component price the suppliers use this information to compete on quantity we find that relative to rfq which is more challenging for the manufacturer to characterize the supplier response due to the possibility of supplier interaction the benefit to the manufacturer from posting a bid increases with the number of suppliers due to increased intensity of competition if the new component is from an emerging industry where there is little mutual awareness among candidate suppliers then regardless of number of suppliers expected manufacturer profit is higher under rfq posting a bid is more likely to benefit the manufacturer when the new component is from a more established industry with a high degree of awareness among candidate suppliers

a brief empirical note on the tiebout hypothesis and state income tax policies some years ago tiebout 1956 418 hypothesized that the consumervoter may be viewed as picking that community which best satisfies his preference pattern for public goods the consumer voter moves to that community whose local government best satisfies his set of preferences based upon this argument by tiebout this brief note seeks to empirically examine the impact of state income tax policy upon the geographic mobility of consumer voters in the united states more specifically we attempt to determine whether the existence of a state income tax significantly influences the in migration of consumer voters naturally the analysis includes suitable non tax control variables to reflect other factors which may influence the migration decision calculus

assistance to the poor in a federal system abstract this paper explores the roles of different levels of government in assisting the poor using a model incorporating utility interdependence the paper first presents some theoretical results indicating how levels of poor relief vary with the extent of mobility of the poor under both centralized and decentralized systems of support it then provides a survey of the empirical work on migration of the poor along with a brief historical discussion of the experience under the english poor laws the concluding section turns to normative issues and contends that mobility of the poor is a basic source of inefficiency in wholly decentralized systems of support this inefficiency along with certain other equity considerations establishes a role for the central government in assistance to the poor

the hunt for party discipline in congress ttt e analyze party discipline in the house of representatives between 1947 and 1998 the effects of 1 v party pressures can be represented in a spatial model by allowing each party to have its own cutting line on roll call votes adding a second cutting line makes at best a marginal improvement over the standard single line model analysis of legislators who switch parties shows however that party discipline is manifest in the location of the legislator s ideal point in contrast to our approach we find that the snyder groseclose method of estimating the influence of party discipline is biased toward exaggerating party effects

does the size of the legislature affect the size of government evidence from two natural experiments this paper makes use of regression discontinuity designs to estimate the effect of the number of legislators on the size of government the results indicate a negative effect i e the larger the size of the legislature the smaller is the size of government this runs counter to conventional wisdom one potential explanation is that more legislators can better control a budget maximizing bureaucracy i present evidence that is consistent with the proposed mechanism

a stochastic and asymmetric information framework for a dominant manufacturer supply chain abstract consider a dominant manufacturer wholesaling a product to a retailer who in turn retails it to the consumers at p unit the retail market demand volume varies with p according to a given demand curve this basic system is commonly modeled as a manufacturer stackelberg ms game under a deterministic and symmetric information det sym i framework we first explain the logical flaws of this framework which are i the dominant manufacturer leader will have a lower profit than the retailer under an iso elastic demand curve ii in some situations the system s correct solution can be hyper sensitive to minute changes in the demand curve iii applying volume discounting while keeping the original ms profit maximizing objective leads to an implausible degenerate solution in which the manufacturer has dictatorial power over the channel we then present an extension of the stochastic and asymmetric information sto asy i framework proposed in lau and lau lau a lau h s 2005 some two echelon supply chain games improving from deterministic symmetric information to stochastic asymmetric information models european journal of operational research 161 1 203 223 coupled with the notion that a profit maximizing dominant manufacturer may implement not only ms but also pm i e using a manufacturer imposed maximum retail price we show that this new framework resolves all the logical flaws stated above along the way we also present a procedure for the dominant manufacturer to design a profit maximizing volume discount scheme using stochastic and asymmetric demand information using our sto asy i framework to resolve the logical flaws of the det sym i framework also reveals two noteworthy points i the attractiveness of the perfectly legal but overlooked channel coordination mechanism pm and ii volume discounting as a means for the dominant manufacturer to benefit from information known only to the retailer

fragmented fiscal policy abstract this paper explores on a panel of 19 oecd countries the role of fragmentation in determining fiscal outcomes over the 1970 95 period we first define the notion of fragmentation of fiscal policy making as the degree to which the costs of a dollar of aggregate expenditure are internalized by individual decision makers empirically this notion has two key logical components the number of decision makers and the rules of the game or the budget process in turn the number of decision makers can refer to the number of parties in a coalition or the number of ministers in the cabinet we test all these determinants against each other and against perhaps the oldest explanation of all ideology we show that cabinet size and to a lesser degree coalition size and ideology are significant and robust determinants of fiscal outcomes in particular transfers are the budget items most affected by these factors

tiebout or not tiebout the market metaphor and america s devolution debate the market metaphor of intergovernmental choice as a spur to efficiency formalized by charles m tiebout is often invoked to support the shift away from washington and toward the states but the model translates badly to governments governmental entry and exit is costly public sector co11usion often serves citizens interests heterogeneous mobility distorts the signals sent by interstate migration and while tiebout and followers condition efficiency predictions on optimal distribution the u s devolution movement coincides with rising inequality and has gone furthest where distribution matters most the metaphor is misapplied devolution will likely do more to enfeeble government than to improve it

choosing electoral rules theory and evidence from us cities this paper studies the choice of electoral rules in particular the question of minority representation majorities tend to disenfranchise minorities through strategic manipulation of electoral rules with the aim of explaining changes in electoral rules adopted by us cities particularly in the south we show why majorities tend to adopt winner take all city wide rules at large elections in response to an increase in the size of the minority when the minority they are facing is relatively small in this case for the majority it is more effective to leverage on its sheer size instead of risking to concede representation to voters from minority elected districts however as the minority becomes larger closer to a fifty fifty split the possibility of losing the whole city induces the majority to prefer minority votes to be confined in minority packed districts single member district rules serve this purpose we show empirical results consistent with these implications of the model

divided government versus incumbency externality effect quasi experimental evidence on multiple voting decisions abstract this paper explores the causal relationship between vote outcomes in different elections we ask 1 does the partisan identity of the mayor influence the voter s decision in subsequent town council elections 2 do voters condition their vote for the mayor on the result of the last council election the analysis mainprod type flply relies on a regression discontinuity design focusing on close election outcomes based on municipal level data for germany we find that the party of the mayor can receive a significant bonus in the next town council election moreover voters punish mayor candidates of parties that performed strongly in earlier council elections throughout the paper we highlight how these findings can be related to an incumbency externality effect and to the theory of divided government

vertical strategic interaction implications for channel pricing strategy this paper examines two strategic pricing decisions within channels using foresight i e price leadership and considering category implications i e product line pricing are price leadership and product line pricing always the best pricing strategies for a channel member if not when does this occur and why by investigating these questions we address some major concerns of both marketing practitioners and scholars interested in channel management issues in addition this study provides an indepth discussion on why previous analytic studies produced answers to these questions that depend upon the choice of the form of demand functions as such this study should significantly resolve the debate among analytic marketing modelers about the right demand specification at the core of our discussion lies the concept of vertical strategic interaction which is defined in terms of the direction of a channel member s reaction to the actions of its channel partner within a given demand structure specifically if a channel member s best reaction is to reduce its margin when its channel partner increases its margin the type of vertical strategic interaction is referred to as vertical strategic substitutability vss if the best reaction is to increase the margin the environment is referred to as vertical strategic complementarity vsc if the best reaction is no margin change it is referred to as vertical strategic independence vsi using a game theoretic approach we demonstrate that these three types of vertical strategic interactions represent a key driving force for optimal decisions on channel price leadership and product line pricing our investigation involves mathematical analyses of an industry model composed of two manufacturers selling competing products both carried by two competing retailers as such the model allows for retailer product line pricing as well as manufacturer and retailer level competition in addition this general model can be used to analyze three more restrictive industry settings often found in the channels literature i e a bilateral monopoly jeuland and shugan jeuland abel steven m shugan 1983 managing channel profits marketing sci 2summer 239 72 two competing manufacturers selling through competing franchised retailers mcguire and staelin

retailer using product line pricing choi choi s chan 1991 price competition in a channel structure with a common retailer marketing sci 10fall 271 96 unlike many other channel studies most of our analyses are performed without assuming particular functional forms of demand curves thus this paper provides greater assurance that the insights from this stream of research are broadly applicable not only across industry structures but also across demand conditions the paper starts out by defining three different rules for how prices are set the manufacturer uses foresight the retailer uses foresight and neither channel member uses foresight we then show a one to one mapping between the type of vertical strategic interaction and the optimality of channel price leadership specifically a channel member finds it profitable to be a price leader for vss but prefers to be a follower for vsc for vsi channel members are indifferent to the channel price leadership issue as it has no effect on channel member profits we also show that there exist conditions under which a retailer might see a reduction in profits when it changes its policy from non product line pricing to product line pricing such conditions arise when the retailer is not a price leader and the environment is characterized by vss or vsc at a more general level this study suggests not only the value but also the cost to a firm for using superior knowledge i e foresight and or product line pricing in making strategic marketing decisions in this way ignorance can be bliss we also explore the link between demand characteristics and the three types of vertical strategic interaction we show that the type of vertical strategic interaction present in a given environment is closely related with the convexity of the demand curve and the level of demand for a given price interestingly we find that linearity of demand is not a necessary condition for any of the three types of vertical strategic demand function consequently in evaluating the robustness of analytic analyses it may be more important to determine the type of vertical strategic interaction assumed instead of whether the demand is linear or nonlinear finally our results are limited to situations where the channels are not coordinated and the retailer s precommitment to particular pricing policy and decision is credible although such situations still capture a significant portion of reality we acknowledge that the insights from this study might not be applicable in all situations

assessing the importance of tiebout sorting local heterogeneity from 1850 to 1990 this paper argues that long run trends in geographic segregation are inconsistent with models where residential choice depends solely on local public goods the tiebout hypothesis we develop an extension of the tiebout model that predicts as mobility costs fall the heterogeneity across communities of individual public good preferences and of public good provision must weakly increase given the secular decline in mobility costs these predictions can be evaluated using historical data we find decreasing heterogeneity in policies and proxies for preferences across i a sample of u s municipalities 1870 1990 ii all boston area municipalities 1870 1990 and iii all u s counties 1850 1990

how do senators vote disentangling the role of voter preferences party affiliation and senate ideology this paper develops a methodology for consistently estimating the relative weights in senator utility functions despite the fact that senator ideologies are unobserved the empirical results suggest that voter preferences are assigned only one quarter of the weight in senator utility functions the national party line also has some influence but the senator s own ideology is the primary determinant of roll call voting patterns these results cast doubt on the empirical relevance of the median voter theorem estimation of the model requires only roll call voting data making it widely applicable copyright 1996 by american economic association

short versus long coalitions electoral accountability and the size of the public sector this article examines the policy consequences of the number of parties in government we argue that parties externalize costs not borne by their support groups larger parties thus internalize more costs than small parties because they represent more groups this argument implies that the public sector should be larger the more parties there are in the government coalition we test this prediction using yearly time series cross sectional data from 1970 to 1998 in 17 european countries we find that increasing the number of parties in government increases the fraction of gdp accounted for by government spending by close to half a percentage point or more than one billion current dollars in the typical year we find little support for the alternative claim that the number of legislative parties affects the size of the public sector except via the number of parties in government

electoral rules and minority representation in u s cities of minority representation majorities tend to disenfranchise minorities through strategic manipulation of electoral rules with the aim of explaining changes in electoral rules adopted by u s cities particularly in the south we show why majorities tend to adopt winner take all city wide rules at large elections in response to an increase in the size of the minority when the minority they are facing is relatively small in this case for the majority it is more effective to leverage on its sheer size instead of risking conceding representation to voters from minority elected districts however as the minority becomes larger closer to a fifty fifty split the possibility of losing the whole city induces the majority to prefer minority votes to be confined in minority packed districts single member district rules serve this purpose we show empirical results consistent with these implications of the model in a novel data set covering u s cities and towns from 1930 to 2000

do voters affect or elect policies evidence from the u s house there are two fundamentally different views of the role of elections in policy formation in one view voters can affect candidates policy choices competition for votes induces politicians to move toward the center in this view elections have the effect of bringing about some degree of policy compromise in the alternative view voters merely elect policies politicians cannot make credible promises to moderate their policies and elections are merely a means to decide which one of two opposing policy views will be implemented we assess which of these contrasting perspectives is more empirically relevant for the u s house focusing on elections decided by a narrow margin allows us to generate quasi experimental estimates of the impact of a randomized change in electoral strength on subsequent representatives roll call voting records we find that voters merely elect policies the degree of electoral strength has no effect on a legislator s voting behavior for example a large exogenous increase in electoral strength for the democratic party in a district does not result in shifting both parties nominees to the left politicians inability to credibly commit to a compromise appears to dominate any competition induced convergence in policy

economics of devolution decentralization in the uk some questions and answers mcgregor p g and swales k 2005 economics of devolution decentralization in the uk some questions and answers regional studies 39 477 494 the paper explores the economic implications of the radical process of devolution decentralization and delegation of decision making and policy delivery initiated by the post 1997 uk labour government it is argued that the economies of all the presently devolved regions ultimately suffer if the barnett formula is rigorously imposed it is shown that the efficiency of devolving fiscal authority involves a balance of positive and negative elements depending on wage bargaining and migration responses it is then argued that delegation devolution of regional economic development policies while exploiting regional information advantages neglects regional economic interdependence so there are potential gains from greater cooperation coordination
