fighting multiple tax havens this paper develops a competition theory framework that evaluates an important aspect of the oecd s harmful tax practices initiative against tax havens we show that the sequential nature of the process is harmful and more costly than a big bang multilateral agreement the sequentiality may even prevent the process from being completed successfully closing down a subset of tax havens reduces competition among the havens that remain active this makes their tax haven business more profitable and shifts a larger share of rents to these remaining tax havens making them more reluctant to give up their tax haven business moreover the outcome of this process reducing the number of tax havens but not eliminating them altogether may reduce welfare in the oecd

an n person pure bargaining game abstract we propose an n person pure bargaining game which generalizes rubinstein s two person bargaining game and show that there exists a unique perfect equilibrium outcome the solution approaches the n person nash solution as defined by chae the n person nash bargaining solution with time preference econ lett 41 1993 21 24 in the time preference framework as the time lapse between bargaining rounds goes to 0 journal of economic literature classification number c78

free entry and regulatory competition in a global economy abstract this paper examines the optimal entry policy toward oligopoly in a global economy we show that free entry results in too much competition for the world but each country s corrective tax policy unless internationally coordinated proves suboptimal because of international policy spillovers thus globalization prevents countries from pursuing the optimal entry policy however globalization also generates the gains from trade when countries are small the gains from trade dominate the losses from a suboptimal entry policy but as markets grow the result is reversed making trade inferior to autarky therefore the need for tax harmonization grows as the world economy grows this paper also contributes to the international tax competition literature through the discovery of the reverse home market effect

the role of firm size in bilateral bargaining a study of the cable television industry we examine the effect of buyer merger on bilateral negotiations between a supplier and n buyers merger may have bargaining effects in addition to the usual efficiency effects the effect of merger on the buyers bargaining position depends on the curvature of the supplier s gross surplus function merger enhances worsens the buyers bargaining position if the function is concave convex based on a panel of advertising revenue in the cable television industry our estimates indicate that the gross surplus function for suppliers of program services is convex this result suggests that cable operators integrate horizontally to realize efficiency gains rather than to enhance their bargaining position vis a vis program suppliers

foreign ownership and corporate income taxation an empirical evaluation abstract foreign ownership allows countries to effectively export part of their corporate tax burden hence countries with high foreign ownership are expected to impose relatively high corporate taxes the findings of this paper suggest that there indeed is an economically significant positive relationship between foreign ownership and tax burdens in europe already significant foreign ownership levels in europe offer an explanation for the absence of a race to the bottom in corporate tax levels

backward stealing and forward manipulation in the wto abstract motivated by the structure of wto negotiations we analyze a bargaining environment in which negotiations proceed bilaterally and sequentially under the most favored nation mfn principle we identify backward stealing and forward manipulation problems that arise when governments bargain under the mfn principle in a sequential fashion we show that these problems impede governments from achieving the multilateral efficiency frontier unless further rules of negotiation are imposed we identify the wto nullification or impairment and renegotiation provisions and its reciprocity norm as rules that are capable of providing solutions to these problems in this way we suggest that wto rules can facilitate the negotiation of efficient multilateral trade agreements in a world in which the addition of new and economically significant countries to the world trading system is an ongoing process

corporate taxes and the location of intangible assets within multinational firms intangible assets like patents and trademarks are increasingly seen as the key to competitive success and as the drivers of corporate profit moreover they constitute a major source of profit shifting opportunities in multinational enterprises mnes due to a highly intransparent transfer pricing process this paper argues that for both reasons mnes have an incentive to locate intangible property at affiliates with a relatively low corporate tax rate using panel data on european mnes and controlling for unobserved time constant heterogeneity between affiliates we find that the lower a subsidiary s corporate tax rate relative to other affiliates of the multinational group the higher is its level of intangible asset investment this effect is statistically and economically significant even after controlling for subsidiary size and accounting for a dynamic intangible investment pattern

bargaining binding contracts and competitive wages in a model where many workers bargain with one firm and sign binding contracts we show existence of a stationary subgame perfect equilibrium if the production function satisfies decreasing return

on governing multilateral transactions with bilateral contracts bilateral contracts while neither negotiated nor enforced in an integrated way are nevertheless often interrelated both economically and strategically owing to production or consumption complementarities and to asymmetric information a set of bilateral contracts forms a mechanism with special properties this mechanism forms a contract equilibrium if there is no joint incentive for a supplier and any individual customer unilaterally to alter the terms of their contract if agents preferences are risk neutral in money income and if their private information is independent then there exists a contract equilibrium that implements efficient transactions if in addition preferences are strictly concave and differentiable in goods and services and technologically feasible sets are suitably convex then this equilibrium is essentially unique

the origins of intergenerational associations lessons from swedish adoption data we use unique swedish data with information on adopted children s biological and adoptive parents to estimate intergenerational mobility associations in earnings and education we argue that the impact from biological parents captures broad prebirth factors including genes and prenatal environment and the impact from adoptive parents represents broad postbirth factors such as childhood environment we find that both pre and postbirth factors contribute to intergenerational earnings and education transmissions and that prebirth factors are more important for mother s education and less important for father s income we also find some evidence for a positive interaction effect between postbirth environment and prebirth factors

intra firm bargaining under non binding contracts we present a new methodology for studying the problem of intra firm bargaining based on the notion that contracts cannot commit the firm and its agents to wages and employment we develop and analyse a general non cooperative multilateral bargaining framework between the firm and its employees and consider outcomes which are immune to renegotiations by any party equilibrium firm profits are characterizable as both a weighted average of a neo classical non bargaining firm s profits and a generalization of shapley value for a corresponding cooperative game furthermore the resulting payoffs induce economically significant distortions in the firm s input and organizational design decisions

bilateralism multilateralism and the quest for global free trade abstract we develop an equilibrium theory of trade agreements in which both the degree and the nature bilateral or multilateral of trade liberalization are endogenously determined to determine whether and how bilateralism matters we also analyze a scenario where countries pursue trade liberalization on only a multilateral basis we find that when countries have asymmetric endowments or when governments value producer interests more than tariff revenue and consumer surplus there exist circumstances where global free trade is a stable equilibrium only if countries are free to pursue bilateral trade agreements by contrast under symmetry both bilateralism and multilateralism yield global free trade

should tax policy favor high or low productivity firms heterogeneous firm productivity raises the question of whether governments should pursue pick the winner strategies by subsidizing highly productive firms more or taxing them less than their less productive counterparts we study this issue in a setting where governments can set differentiated effective tax rates in an oligopolistic industry in which firms with two productivity levels co exist we show that the optimal structure of tax differentiation depends critically on the feasible level of the corporate profit tax which in turn depends on the degree of international tax competition when tax competition is weak and optimal profit tax rates are high favoring high productivity firms is indeed the optimal policy when tax competition is aggressive and profit taxes are low however the optimal tax policy reverses and favors low productivity firms

bargaining in a network of buyers and sellers abstract we analyze bargaining between buyers and sellers who are connected by an exogenously given network players can make repeated alternating public offers that may be accepted by any of the responders linked to each specific proposer our purpose is to find the conditions of the network which drive the price distribution in equilibrium this paper uses graph theory tools to provide necessary and sufficient conditions regarding the architecture of networks for the subgame perfect equilibrium of the bargaining game to coincide with the walrasian outcome

moving to opportunity in boston early results of a randomized mobility experiment this paper examines the short run impacts of a change in residential neighborhood on the well being of low income families using evidence from a program in which eligibility for a housing voucher was determined by random lottery we examine the experiences of households at the boston site of moving to opportunity mto a demonstration program in five cities families in high poverty public housing projects applied to mto and were assigned by lottery to one of three groups experimental offered mobility counseling and a section 8 subsidy valid only in a census tract with a poverty rate of less than 10 percent section 8 comparison offered a geographically unrestricted section 8 subsidy or control offered no new assistance but continued to be eligible for public housing our quantitative analyses of program impacts uses data on 540 families from a baseline survey at program enrollment a follow up survey administered l to 3 5 years after random assignment and state administrative data on earnings and welfare receipt 48 percent of the experimental group and 62 percent of the section 8 comparison group moved through the mto program one to three years after program entry families in both treatment groups were more likely to be residing in neighborhoods with low poverty rates and high education levels than were families in the control group however while members of the experimental group were much more likely to be residing in suburban communities than were those in the section 8 group the lower program take up rate among the experimental group resulted in more families remaining in the most distressed communities households in both treatment groups experienced improvements in multiple measures of well being relative to the control group including increased safety improved health among household heads and fewer behavior problems among boys experimental group children were also less likely to be a victim of a personal crime to be injured or to experience an asthma attack there are no significant impacts of either mto treatment on the employment earnings or welfare receipt of household heads in the first three years after random assignment

cultural transmission and discrimination workers can have good or bad work habits these traits are transmitted from one generation to the next through a learning and imitation process which depends on parents investment in the trait and the social environment where children live if a sufficiently high proportion of employers have taste based prejudices against minority workers we show that their prejudices are always self fulfilled in steady state and minority workers end up having on average worse work habits than majority workers this leads to a ghetto culture affirmative action can improve the welfare of minorities whereas integration can be beneficial to minority workers but detrimental to workers from the majority group

the non existence of pairwise proof equilibrium abstract private bilateral contracting between a supplier and competing customers admits multiple equilibria we show that requiring equilibrium to be pairwise proof immune to bilateral deviations by the supplier and any customer can imply non existence of equilibrium in normal environments

capital income and profit taxation with foreign ownership of firms abstract this paper establishes optimal rules for capital income and profits taxation in the open economy with or without foreign ownership of domestic firms we show that if there are constraints on the feasibility of profits taxation both saving and investment taxes generally enter the optimal tax package if instead profits can be fully taxed then source based investment taxes vanish if domestic firms are in part owned by foreigners then source based investment taxes can be used to shift income away from these to domestic citizens and they may even be used to finance lump sum transfers to domestic residents

in praise of tax havens international tax planning and foreign direct investment abstract the multinationalization of corporate investment in recent years has given rise to a number of international tax avoidance schemes that may be eroding tax revenues in industrialized countries but which may also reduce tax burdens on mobile capital and so facilitate investment both the welfare effects of and the optimal response to international tax planning are therefore ambiguous evaluating these factors in a simple general equilibrium model we find that citizens of high tax countries benefit from some tax planning paradoxically if tax rates are not too high an increase in tax planning activity causes a rise in optimal corporate tax rates and a decline in multinational investment thus fears of a race to the bottom in corporate tax rates may be misplaced

nash in nash tariff bargaining abstract we provide an equilibrium analysis of the efficiency properties of simultaneous bilateral tariff negotiations in a three country model of international trade we consider the setting in which discriminatory tariffs are allowed and we utilize the nash in nash solution concept of horn and wolinsky 1988 we allow for a general family of political economic country welfare functions and assess efficiency relative to these welfare functions we establish a sense in which the resulting tariffs are inefficient and too low so that excessive liberalization occurs from the perspective of the three countries

peer effects and social networks in education this paper studies whether structural properties of friendship networks affect individual outcomes in education we first develop a model that shows that at the nash equilibrium the outcome of each individual embedded in a network is proportional to her katz bonacich centrality measure this measure takes into account both direct and indirect friends of each individual but puts less weight to her distant friends we then bring the model to the data by using a very detailed dataset of adolescent friendship networks we show that after controlling for observable individual characteristics and unobservable network specific factors the individual s position in a network as measured by her katz bonacich centrality is a key determinant of her level of activity a standard deviation increase in the katz bonacich centrality increases the pupil school performance by more than 7 percent of one standard deviation

bilateral bargaining in networks abstract each connected pair of nodes in a network can jointly produce one unit of surplus a maximum number of linked nodes is selected in every period to bargain bilaterally over the division of the surplus according to the protocol proposed by rubinstein and wollinsky equilibrium in a market with sequential bargaining econometrica 53 1985 1133 1150 all pairs which reach an agreement obtain the discounted payoffs and are removed from the network this bargaining game has a unique subgame perfect equilibrium that induces the dulmage mendelsohn decomposition partition of the bipartite network of the set of nodes in this network

a theory of buyer seller networks this paper introduces a new model of exchange networks rather than markets of buyers and sellers it begins with the empirically motivated premise that a buyer and seller must have a relationship a link to exchange goods networks buyers sellers and the pattern of links connecting them are common exchange environments this paper develops a methodology to study network structures and explains why agents may form networks in a model that captures characteristics of a variety of industries the paper shows that buyers and sellers acting strategically in their own self interests can form the network structures that maximize overall welfare

price discrimination and bargaining empirical evidence from medical devices many important issues in business to business markets involve price discrimination and negotiated prices situations where theoretical predictions are ambiguous this paper uses new panel data on buyer supplier transfers and a structural model to empirically analyze bargaining and price discrimination in a medical device market while many phenomena that restrict price discrimination are suggested as ways to decrease hospital costs e g mergers group purchasing organizations and transparency i find that 1 non discriminatory pricing actually works against hospitals because competition is more intense under price discrimination and 2 results depend ultimately on a previously unexplored bargaining effect

the economic consequences of social network structure we survey the literature on the economic consequences of the structure of social networks we develop a taxonomy of macro and micro characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in determining learning diffusion decisions and resulting behaviors we also discuss the challenges of accounting for the endogeneity of networks in assessing the relationship between the patterns of interactions and behaviors

mergers when prices are negotiated evidence from the hospital industry in recent years many hospitals have merged in part to gain bargaining leverage with managed care organizations mcos we investigate the price impact of hospital mergers by formulating and estimating an equilibrium bargaining model between hospital systems and managed care health insurers over prices for inpatient services we estimate the parameters of the model using claims and discharge data from northern virginia in 2006 inova health system proposed to acquire prince william hospital we nd that this merger would have raised prices signicantly and that the remedy of separate bargaining imposed by the ftc in a separate hospital case would have resulted in a larger price increase

the nash program non convex bargaining problems we define and characterize an extension of the nash bargaining solution to non convex bargaining problems and in the spirit of the nash program of implementing cooperative solutions non cooperatively we show that this solution is supported by rubinstein s econometrica 50 1982 97 110 model of bargaining and its corresponding set of stationary subgame perfect equilibria

the demand for tax haven operations what types of firms establish tax haven operations and what purposes do these operations serve analysis of affiliate level data for american firms indicates that larger more international firms and those with extensive intrafirm trade and high r and d intensities are the most likely to use tax havens tax haven operations facilitate tax avoidance both by permitting firms to allocate taxable income away from high tax jurisdictions and by reducing the burden of home country taxation of foreign income the evidence suggests that the primary use of affiliates in larger tax haven countries is to reallocate taxable income whereas the primary use of affiliates in smaller tax haven countries is to facilitate deferral of u s taxation of foreign income firms with sizeable foreign operations benefit the most from using tax havens an effect that can be evaluated by using foreign economic growth rates as instruments for firm level growth of foreign investment outside of tax havens one percent greater sales and investment growth in nearby non haven countries is associated with a 1 5 to 2 greater likelihood of establishing a tax haven operation

tax evasion fiscal competition and economic integration abstract this paper examines the implications of tax evasion for fiscal competition and tax harmonization policies in an economic union first for symmetric countries it proves that the equilibrium values of the tax and audit rates are less than optimal tax harmonization alone will also lead to a less than optimal audit rate second for asymmetric countries the paper shows that integration may turn an honest country into an evading one it argues that tax harmonization alone may be a bad policy in that it can make both countries worse off it may also cause an otherwise honest country to turn to evasion

bilateral monopolies and incentives for merger the paper presents a model of duopoly in which firms acquire inputs through bilateral monopoly relations with suppliers it combines a bargaining model with a duopoly model to examine how input pri

non cooperative bargaining and union formation we study a union formation decision problem when workers consist of two groups distinguished by different productivities workers may form either a joint union or two separate unions the whole decision process is modelled as an extensive form bargaining game workers form a joint union when the sizes or productivities of the groups are similar in the first case there is a wage differential which is more less than proportional to the productivity difference if the size of the more productive is smaller larger than that of the less productive in the second case there is no wage differential in this paper we study a union formation decision problem when workers consist of two groups distinguished by different productivities they may form either a joint union or two separate unions depending on the relative size and productivity of the two groups the whole decision process is modelled as an extensive form bargaining game in which the two groups of workers bargain with each other as well as with a firm the labour market is sharply distinguished from the goods market by the widespread practice of collective bargaining usually several groups of workers with different characteristics for example skill level or geographical location are represented as a single unit and or several employers form a single bargaining unit against a giant union this multiplicity of bargaining units creates a complicated bargaining structure and makes the outcome hard to analyse the purpose of this paper is to provide a model which captures this complexity and at the same time clarifies the underlying structure of bargaining power although economists have been aware of the multiplicity problem for a long time it has been received little rigorous theoretical treatment until recently davidson 1985 examined the possible gains that can be obtained by trade unions through joint bargaining in an oligopolistic industry there is a positive externality due to the fact that a higher wage rate in one firm generates a larger demand hence a higher wage in competing firms when a joint union is organized these externalities are internalized to the benefit of workers horn and wolinsky 1985 investigated the equilibrium pattern of unionization in an industry where a firm employs two types of workers they found that workers tend to form a single union when the two types are substitutes in the sense that the incremental contribution of one group to the firm s revenue is decreasing with respect to the size of the other group since workers bargaining power comes from the loss that they can

multilateral trade bargaining and dominant strategies motivated by general agreement on tariffs and trade bargaining behavior and renegotiation rules we construct a three country two good general equilibrium model of trade and examine multilateral tariff bargaining under the constraints of nondiscrimination and multilateral reciprocity for a general representation of government preferences we identify the bargaining outcomes that can be achieved using dominant strategy proposals for all countries in our analysis dominant strategy outcomes emerge when tariff proposals are followed by multilateral rebalancing the resulting bargaining outcome is efficient relative to government preferences if and only if the initial tariff vector positions the initial world price at its politically optimal level

multilateral trade negotiations bilateral opportunism and the rules of gatt wto abstract trade negotiations occur through time and between the governments of many countries an important issue is thus whether the value of concessions that a government wins in a current negotiation may be eroded in a future bilateral negotiation to which it is not party we identify rules of negotiation that serve to protect the welfare of governments that are not participating in the bilateral negotiation our main finding is that the two central principles of gatt wto nondiscrimination mfn and reciprocity preserve the welfare of nonparticipating governments and therefore offer a first line of defense against bilateral opportunism

saving taxes through foreign plant ownership this paper analyzes to which extent foreign plant ownership involves lower tax payments than domestic plant ownership we employ a model of endogenous foreign subsidiary ownership to derive a set of empirically testable hypotheses about the differential taxation of foreign and domestically owned subsidiaries we assess these hypotheses in a data set of 33 577 european foreign and domestically owned manufacturing plants we identify a significant tax saving of endogenous foreign owner ship on average foreign owners pay 594 euros per employee or about 56 percent less than domestic owners of similar subsidiaries this effect is larger in thinner markets with fewer plants in markets with a greater relative presence of foreign owners and for foreign owners of larger plants

contracting with externalities the paper studies inefficiencies arising in contracting between one principal and n agents when the utility of each agent depends on all agents trades with the principal when the principal commits to a set of publicly observable bilateral contract offers the arising inefficiency is due entirely to the externalities imposed on non signers in contrast when the principal s offers are privately observed the distortion is due to the externalities given agents equilibrium trades comparison of the two externalities determines the relative efficiency of the two contracting regimes in both cases we show that when n is large each agent can be treated as non pivotal provided that appropriate continuity assumptions are satisfied we also study the case in which the principal can condition each agent s trade on other agents messages we characterize the set of such mechanisms in which each agent s participation is voluntary when the principal can commit to any such mechanism she implements the first best outcome while threatening each deviator with the harshest possible punishment however in the presence of noise that goes to zero slower than n goes to infinity in the limit we obtain a generally inefficient outcome in which each agent feels non pivotal

does school quality matter returns to education and the characteristics of public schools in the united states this paper estimates the effects of school quality measured by the pupil teacher ratio average term length and relative teacher pay on the rate of return to education for men born between 1920 and 1949 using earnings data from the 1980 census we find that men who were educated in states with higher quality schools have a higher return to additional years of schooling rates of return are also higher for individuals from states with better educated teachers and with a higher fraction of female teachers holding constant school quality measures however we find no evidence that parental income or education affects average state level rates of return

the welfare effects of bundling in multichannel television markets we measure how the bundling of television channels affects short run welfare we estimate an industry model of viewership demand pricing bundling and input market bargaining using data on ratings purchases prices bundles and input costs we conduct simulations of a la carte policies that require distributors to offer individual channels for sale to consumers we estimate that negotiated input costs rise by 103 0 percent under a la carte these higher input costs offset consumer benefits from purchasing individual channels mean consumer and total surplus change by an estimated 5 4 to 0 2 percent and 1 7 to 6 0 percent respectively jel d12 l11 l51 l82 m31

do when and where matter initial labor market conditions and immigrant earnings this article investigates the long term effects on immigrant earnings and employment of labour market conditions encountered upon arrival we find that early earnings assimilation depends crucially on a favourable national labour market exposure to high local unemployment rates also affects individuals for at least ten years to handle the issue of selective migration we compare refugees entering sweden during a severe and unexpected recession to refugees arriving during a preceding economic boom the analysis of effects at the local level exploits a governmental refugee settlement policy to get exogenous variation in local labour market conditions

the effects of exposure to better neighborhoods on children new evidence from the moving to opportunity experiment the moving to opportunity mto experiment offered randomly selected families housing vouchers to move from high poverty housing projects to lower poverty neighborhoods we analyze mto s impacts on children s long term outcomes using tax data we find that moving to a lower poverty neighborhood when young before age 13 increases college attendance and earnings and reduces single parenthood rates moving as an adolescent has slightly negative impacts perhaps because of disruption effects the decline in the gains from moving with the age when children move suggests that the duration of exposure to better environments during childhood is an important determinant of children s long term outcomes jel i31 i38 j13 r23 r38

bargaining in stationary networks we study an infinite horizon game in which pairs of players con nected in a network are randomly matched to bargain players who reach agreement are replaced by new players at the same positions in the network we show that all equilibria are payoff equivalent the payoffs and the set of agreement links converge as players become patient several new concepts mutually estranged sets partners and shortage ratios provide insights into the relative strengths of the positions in the network we develop a procedure to deter mine the limit equilibrium payoffs for all players characterizations of equitable and nondiscriminatory networks are also obtained jel c78 d85 competitive equilibrium theory assumes large and anonymous markets in which every buyer can trade with every seller underlying these assumptions are standard goods and services that may be traded at low transaction costs by agents who are not in specific relationships with one another however in many markets goods and services are heterogeneous e g cars apartments or need to be tailored to particular needs e g manufacturing inputs technical support furthermore trad ing opportunities may depend on transportation costs social relationships infor mation advertising trust technological compatibility joint business opportunities free trade agreements etc in such cases it is natural to model the market using a network where only pairs of connected agents may engage in exchange new theories are needed to explore the influence of the network structure on market outcomes many questions arise how does an agent s position in the net work determine his bargaining power and the local prices he faces who trades with whom and on what terms when are prices uniform in the network one possible conjecture is that an agent s bargaining power is determined by his relative number of connections in the network however this simple theory is implausible consider the network of four sellers located at the top nodes and nine buyers located at the bottom nodes depicted in figure 1 assume that each seller supplies one unit of a homogeneous indivisible good each buyer demands one unit of the good and all buyers have identical values for the good the buyer located in the middle has the largest number of links in the network as he is connected to each

intergenerational correlation and social interactions in education we propose a dynastic model where individuals are born into an educated or uneducated environment that they inherit from their parents we study the impact of social interactions on the correlation in parent child educational status independently of any parent child interaction when the level of social interactions is decided by a social planner we show that the correlation in education status between generations decreases very fast as social interactions increase in turn when the level of social interactions is decided by the individuals themselves we show that the intergenerational correlation still decreases although less rapidly than with exogenous social interactions

do countries compete over corporate tax rates this paper tests whether oecd countries compete with each other over corporate taxes in order to attract investment we develop two models with firm mobility countries compete only over the statutory tax rate or the effective average tax rate while with capital mobility countries compete only over the effective marginal tax rate we estimate the parameters of reaction functions using data from 21 countries between 1983 99 we find evidence that countries compete over all three measures but particularly over the statutory tax rate and the effective average tax rate this is consistent with a belief amongst governments that location choices by multinational firms are discrete we also find evidence of concave reaction functions consistent with the model outlined in the paper

equilibrium and inefficiency in a community model with peer group effects public service output depends on input expenditures on own personal characteristics and on the characteristics of the other residents in the community the peer group effect in a community model with public expenditures set by voting with migration between communities and with land price differentials capitalization it is shown that communities may become heterogeneous in composition and second best inefficient this equilibrium occurs when the peer group effect is neither too strong nor too weak the inefficiency arises because an externality is created by migration the land price differential does not play the part of the price of the better peer group but of a transfer payment

strong and weak ties in employment and crime this paper analyzes the interplay between social structure and information exchange in two competing activities crime and labor we consider a dynamic model in which individuals belong to mutually exclusive two person groups referred to as dyads there are multiple equilibria if jobs are badly paid and or crime is profitable unemployment benefits have to be low enough to prevent workers for staying too long in the unemployment status because they are vulnerable to crime activities if instead jobs are well paid and or crime is not profitable unemployment benefits have to be high enough to induce workers to stay unemployed rather to commit crime because they are less vulnerable to crime activities also in segregated neighborhoods characterized by high interactions between peers a policy only based on punishment and arrest will not be efficient in reducing crime it has to be accompanied by other types of policies that take into account social interactions

tax evasion tax competition and the gains from nondiscrimination the case of interest taxation in europe this paper uses a game tlieoredc approach to analyse the taxadon of interest income in europe in the presence of tax evasion the model allows tis to assess the success of various reform proposals we argue tbat the tax treatment of nonresidents interest income plays a crucial role when decisions on discriminatio n and on withholding tax rates are made noncooperadvely the outcome is similar to a prisoners dilemma all countries discriminate but in equilihrium internationally mobile portfolio capital evades taxation successfully in contrast if all governments did not discriminate tax competition leads to less tax evasion the integration of capital markets in europe has hrought various benefits at the same time however governments struggle to contain tax evasion international capital flight as an attempt to evade taxes is particularly relevant in the area of taxation of interest income banking secrecy laws in some eu countries and low tax rates in small countries like luxembourg which hoost its role as financial centre have led to the effective elimination ofthe taxation of interest income for some investors the economist speaks not surprisingly about the disappearing taxpayer may 31 1997 several proposals have been made in order to overcome this situation the european commission supports the introduction of a minimum tax rate and or the status of a community resident under the concept of a community resident a country s tax on interest income is independent of the residence of the investor practically realising the source principle by contrast a proposal of the oecd 1977 argues in favour of a maximum withholding tax rate on interest income none of these proposals has been unanimously accepted since gains and losses from non coordinated policies differ greatly across member states the main beneficiary of the present situation is luxembourg which attracts large amounts of foreign capital in particular from germany the united kingdom opposes any coordination for political reasons and because tax coordination may also threaten london s role as the leading financial centre in europe in contrast germany sticks to its traditional bank secrecy law which enables resident investors to evade german taxation by investing abroad

opportunism in multilateral vertical contracting nondiscrimination exclusivity and uniformity comment an input supplier selling to competing downstream firms would benefit from publicly committing at the outset to all contracts efficient commitment however would require complete contracts the authors study instead bilateral contracting without commitment regarding others terms each firm then fears that the supplier might opportunistically renegotiate another s contract to increase bilateral profit at the firm s expense the authors show that nondiscrimination clauses generally cannot curb such third party opportunism even with symmetric firms to reassure firms crude forms of commitment may be adopted this could explain the pervasiveness of exclusivity arrangements and the striking uniformity and intertemporal rigidity of franchise contracts copyright 1994 by american economic association

multiunit bargaining in oligopolistic industries a model of wage determination in unionized oligopolistic industries is developed and used to compare the outcome of collective bargaining under two different bargaining structures one in which the workers of each firm are represented by separate and independent unions local bargaining and one in which a national union represents all workers in the industry in both cases the bargaining problem has a unique outcome with industrywide bargaining resulting in higher wages in addition industrywide unions are inherently stable in that there are no incentives for independent unions to attempt to cheat on the collusive agreement

desegregation and black dropout rates in 1954 the united states supreme court ruled that separate schools for black and white children were inherently unequal this paper studies whether the desegregation plans of the next 30 years benefited black and white students in desegregated school districts data from the 1970 and 1980 censuses suggest desegregation plans of the 1970 s reduced high school dropout rates of blacks by two to three percentage points during this decade no significant change is observed among whites the results are robust to controls for family income parental education and state and region specific trends as well as to tests for selective migration

how urbanization affect employment and social interactions we develop a model where the unemployed workers in the city can find a job either directly or through weak or strong ties we show that in denser areas individuals choose to interact with more people and meet more random encounters weak ties than in sparsely populated areas we also demonstrate that for a low urbanization level there is a unique steady state equilibrium where workers do not interact with weak ties while for a high level of urbanization there is a unique steady state equilibrium with full social interactions we show that these equilibria are usually not socially efficient when the urban population has an intermediate size because there are too few social interactions compared to the social optimum finally even when social interactions are optimal we show that there is over urbanization in equilibrium

negative externalities may cause delay in negotiation we study the strategic equilibria of a negotiation game where potential buyers are affected by identity dependent negative externalities the unique equilibrium of long finitely repeated generic games can either display delay where a transaction can take place only in several stages before the deadline or in spite of the random element in the game a well defined buyer exists that obtains the object with probability close to one

spatial versus social mismatch the aim of this paper is to provide a new mechanism based on social interactions explaining why distance to jobs can have a negative impact on workers labor market outcomes especially ethnic minorities building on granovetter s idea that weak ties are superior to strong ties for providing support in getting a job we develop a model in which workers who live far away from jobs choose to have less connections to weak ties because of the lack of good public transportation in the us it is costly both in terms of time and money to commute to business centers to meet other types of people who can provide other source of information about jobs if distant minority workers mainly rely on their strong ties who are more likely to be unemployed there is then little chance for them of escaping unemployment it is therefore the separation in both the social and physical space that prevents ethnic minorities from finding a job

a dynamic model of weak and strong ties in the labor market the study develops a simple model where workers can obtain a job through either their strong or weak ties it shows that increasing the time spent with weak ties raises the employment rate of workers it also shows that when the job destruction rate or the job information rate increases workers choose to rely more on their weak ties to find a job the model is extended so unemployed workers can also learn of a vacancy directly from an employer results show that equilibrium employment and time spent with weak ties are sometimes but not in all cases positively related

a noncooperative theory of coalitional bargaining the authors explore a sequential offers model of n person coalitional bargaining with transferable utility and with time discounting their focus is on the efficiency properties of stationary equilibria of strictly superadditive games when the discount factor delta is sufficiently large it is shown that delay and the formation of inefficient subcoalitions can occur in equilibrium the latter for some or all orders of proposer however efficient stationary equilibrium payoffs converge to a point in the core as delta approaches one strict convexity is a sufficient condition for there to exist an efficient stationary equilibrium payoff vector for sufficiently high delta

the political economy of the european customs classification customs classification is an important element in a country s trade policy how a good is classified can affect the rate of duty that applies the coverage of non tariff barriers and the formulation and application of rules of origin reclassifications can occur because of the introduction of a new product but also because of protectionist motives this paper is the first attempt at explaining these reclassifications focusing on the european union i examine whether the number of tariff lines in an industry result from the introduction of new products or from protectionist lobbying the analysis focuses on 90 manufacturing industries over 12 years results suggest that protectionist lobbying does play a role in explaining changes in the eu s customs classification

nash in nash bargaining a microfoundation for applied work a nash equilibrium in nash bargains has become the workhorse bargaining model in applied analyses of bilateral oligopoly this paper proposes a non cooperative foundation for nash in nash bargaining that extends the rubinstein 1982 model to multiple upstream and downstream rms assuming there exists gains from trade for each rm pair we prove that there exists an equilibrium with immediate agreement and negotiated prices that correspond to rubinstein prices if and only if the marginal contribution of a set of agreements is weakly greater than the sum of the agreements marginal contributions we provide stronger conditions under which equilibrium prices are unique

forecasting the recovery from the great recession is this time different abstract this paper asks whether the slow recovery of the us economy from the trough of the great recession was anticipated and identifies some of the factors that contributed to surprises in the course of the recovery we construct a narrative using news reports and government announcements to identify policy and financial shocks we then compare forecasts and forecast revisions of gdp to the narrative successive financial and fiscal shocks emanating from europe together with self inflicted wounds from the political stalemate over the us fiscal situation help explain the slowing of the pace of an already slow recovery

bilateral control with vertical contracts when a manufacturer contracts secretly with competing retailers he is subject to opportunism and linear or non linear tariffs may not allow the manufacturer to maintain monopoly prices to analyse the effects of rpm o brien shaffer 1992 use a concept of contract equilibrium which concentrates on pairwise deviations thereby questioning the robustness of the analysis this paper emphasises the distinction between the contract equilibrium and standard non cooperative concepts we advocate for some caution in the use of the former concept as if overlooks an inexistence problem we then confirm the intuition that rpm can help solve the manufacturer s commitment problem this confirms that o brien shaffer s insight is robust and validates the courts reluctance against rpm

should countries control international profit shifting we present a fiscal competition model with two policy instruments the level of corporate taxation and the tightness of control of profit shifting by multinational firms mnf we show that a country may optimally decide not to monitor the mnf for two reasons firstly this country becomes an attractive location for mnf activity despite a high corporate tax secondly as the profits of the mnf become mobile the focus of tax competition is shifted taxation then influences both an mnf s location and the place where it declares its profits

tax competition with parasitic tax havens we develop a tax competition framework in which some jurisdictions called tax havens are parasitic on the revenues of other countries the havens use real resources to help companies camouflage their home country tax avoidance and countries use resources in an attempt to limit the transfer of tax revenues to the havens the equilibrium price for this service depends on the demand and supply for such protection recognizing that taxes on wage income are also evaded we solve for the equilibrium tax rates on mobile capital and immobile labor and we demonstrate that the full or partial elimination of tax havens would improve welfare in non haven countries in part because countries would be induced to increase their tax rates which they have set at inefficiently low levels in an attempt to attract mobile capital we also demonstrate that the smaller countries choose to become tax havens and we show that the abolishment of a sufficiently small number of the relatively large havens leaves all countries better off including the remaining havens
