where enterprises lead people follow links between migration and fdi in germany abstract standard neoclassical models of economic integration are based on the assumptions that capital and labor are substitutes and that the geography of factor market integration does not matter yet these two assumptions are violated if agglomeration forces among factors from specific source countries are at work agglomeration implies that factors behave as complements and that the country of origin matters this paper analyzes agglomeration between capital and labor empirically we use state level german data to answer the question whether and how migration and foreign direct investment fdi are linked stocks of inward fdi and of immigrants have similar determinants and the geography of factor market integration matters there are higher stocks of inward fdi in german states hosting a large foreign population from the same country of origin this agglomeration effect is confined to higher income source countries

common trends and common cycles the existence of a serial correlation common feature among the first differences of a set of i 1 variables implies the existence of a common cycle in the beveridge nelson stock watson decomposition of those variables a test for the existence of common cycles among cointegrated variables is developed the test is used to examine the validity of the common trend common cycle structure implied by flavin s excess sensitivity hypothesis and campbell and mankiw s mixture of rational expectations and rule of thumb hypothesis for consumption and income linear independence between the cointegration and the cofeature vectors is exploited to decompose consumption and income into their trend and cycle components copyright 1993 by john wiley sons ltd

out of sight not out of mind education networks and international trade summary university students typically develop between them long lasting ties of friendship and trust as well as an attachment to their university if they are foreign students they also form a bond to their country of study this paper investigates the impact of university ties on the uk s trade with 167 countries during 1999 2009 i find robust evidence that education network ties boost the uk s bilateral trade flows specifically the impact of networks is stronger on trade between the united kingdom and countries with dissimilar institutions and culture and particularly with post communist economies results are robust to different econometric specifications and regressors

the impossibility of extending random dictatorship to weak preferences random dictatorship has been characterized as the only social decision scheme that satisfies efficiency and strategyproofness when individual preferences are strict we show that no extension of random dictatorship to weak preferences satisfies these properties even when significantly weakening the required degree of strategyproofness

immigration and the diffusion of technology the huguenot diaspora in prussia abstract this paper analyzes long term effects of skilled worker immigration on productivity for the huguenot migration to prussia in 1685 religiously persecuted french huguenots settled in brandenburg prussia and compensated for population losses due to plagues during the thirty years war we combine huguenot immigration lists from 1700 with prussian firm level data on the value of inputs and outputs in 1802 in a unique database to analyze the effects of skilled immigration to places with underused economic potential exploiting this settlement pattern in an instrumental variable approach we find substantial long term effects of huguenot settlement on the productivity of textile manufactories jel j24 j61 l67 n33 n63 o33 o47

a field study on matching with network externalities we study the effects of network externalities within a protocol for matching faculty to offices in a new building using web and survey data on faculty s attributes and choices we identify the different layers of the social network institutional affiliation coauthorships and friendships we quantify the effects of network externalities on choices and outcomes disentangle the layers of the networks and quantify their relative influence finally we assess the protocol used from a welfare perspective our study suggests the importance and feasibility of accounting for network externalities in assignment problems and evaluates techniques that can be employed to this end jel c78 c93 d62 d85 z13

the welfare effects of coordinated assignment evidence from the new york city high school match abstract coordinated single offer school assignment systems are a popular education reform we show that uncoordinated offers in nyc s school assignment mechanism generated mismatches one third of

what floats your boat preference revelation from lotteries over complex goods abstract we examine a type of lottery used to distribute some publicly held resource access rights the lottery provides participants with the opportunity to choose among a set of simple gambles over multi attribute goods participant choices result in an endogenous distribution of success rates over gambles that reflects tradeoffs between the relative desirability of the available goods and the probability of winning when lottery winnings are multi attribute goods lottery outcomes provide sufficient information to estimate hedonic prices marginal utility and marginal rates of substitution among attributes we develop a model for characterizing preferences from this information set we apply our model to idaho s four rivers whitewater recreation lottery which allows applicants to apply for one permit among a large set of alternative river day combinations that provide varying river and weather characteristics this lottery structure shows promise as a foundation for economic experiments for preference revelation

strategic disclosure of feasible options abstract the paper illustrates how people who need to make a joint decision may have an incentive to withhold information regarding the existence of pareto improving options the resulting level of inefficiency varies with the way compromises are reached when the parties have to choose among multiple options various reasonable compromise rules can be ranked unequivocally and a rule resulting in a minimal level of inefficiency is identified qualitative results extend to sequential disclosure enforcing a hard deadline for disclosure may be welfare improving in some circumstances

globalization brain drain and development this paper reviews four decades of economics research on the brain drain with a focus on recent contributions and on development issues we first assess the magnitude intensity and determinants of the brain drain showing that brain drain or high skill migration is becoming a dominant pattern of international migration and a major aspect of globalization we then use a stylized growth model to analyze the various channels through which a brain drain affects the sending countries and review the evidence on these channels the recent empirical literature shows that high skill emigration need not deplete a country s human capital stock and can generate positive network externalities three case studies are also considered the african medical brain drain the exodus of european scientists to the united states and the role of the indian diaspora in the development of india s information technology sector we conclude with a discussion of the implications of the analysis for education immigration and international taxation policies in a global context

why do popular mechanisms lack efficiency in random environments we consider the problem of randomly assigning n indivisible objects to n agents recent research introduced a promising mechanism the probabilistic serial that has superior e ciency properties than the most common real life mechanism random priority on the other hand mechanisms based on gale s celebrated top trading cycles method have long dominated the indivisible goods literature with the exception of the present context thanks to their outstanding e ciency features we present an equivalence

designing random allocation mechanisms theory and applications randomization is commonplace in everyday resource allocation we generalize the theory of randomized assignment to accommodate multi unit allocations and various real world constraints such as group specific quotas controlled choice in school choice and house allocation and scheduling and curriculum constraints in course allocation we develop new mechanisms that are ex ante efficient and fair in these environments and that incorporate certain non additive substitutable preferences we also develop a utility guarantee technique that limits ex post unfairness in random allocations supplementing the ex ante fairness promoted by randomization this can be applied to multi unit assignment problems and certain two sided matching problems jel c78 d82

comparing school choice mechanisms by interim and ex ante welfare recent work has highlighted welfare gains from the use of the boston mechanism over deferred acceptance da in school choice problems in particular finding that when cardinal utility is taken into account boston interim pareto dominates da in certain incomplete information environments with no school priorities we show that these previous interim results are not robust to the introduction of weak priorities however we partially restore the earlier results by showing that from an ex ante utility perspective the boston mechanism pareto dominates any strategyproof mechanism including da even allowing for arbitrary priority structures thus we suggest ex ante pareto dominance as a relevant criterion by which to compare school choice mechanisms this criterion may be of particular interest to school districts as they can be thought of as social planners whose goal is to maximize the overall ex ante welfare of the students

how robust is the capital skill complementarity hypothesis this paper investigates the relation between substitution possibilities in manufacturing production between capital and two labor inputs blue collar and white collar workers griliches found in 1969 that unskilled labor was more easily substituted for by capital than skilled labor griliches called this capital skill complementarity the capital skill complementarity hypothesis has implications for the aggregation of labor inputs as well as for employment of labor categories and income distribution between factors this paper investigates the robustness of the capital skill complementarity hypothesis on swedish data by varying model assumptions concerning economies of scale and technological growth copyright 1992 by mit press

assigning resources to budget constrained agents this article studies different methods of assigning a good to budget constrained agents schemes that assign the good randomly and allow resale may outperform the competitive market in terms of utilitarian efficiency the socially optimal mechanism involves random assignment at a discount an in kind subsidy and a cash incentive to discourage low valuation individuals from claiming the good copyright oxford university press

matching with contracts we develop a model of matching with contracts which incorporates as special cases the college admissions problem the kelso crawford labor market matching model and ascending package auctions we introduce a new law of aggregate demand for the case of discrete heterogeneous workers and show that when workers are substitutes this law is satisfied by profit maximizing firms when workers are substitutes and the law is satisfied truthful reporting is a dominant strategy for workers in a worker offering auction matching algorithm we also parameterize a large class of preferences satisfying the two conditions

the combinatorial assignment problem approximate competitive equilibrium from equal incomes this paper proposes a new mechanism for combinatorial assignment for example assigning schedules of courses to students based on an approximation to competitive equilibrium from equal incomes ceei in which incomes are unequal but arbitrarily close together the main technical result is an existence theorem for approximate ceei the mechanism is approximately efficient satisfies two new criteria of outcome fairness and is strategyproof in large markets its performance is explored on real data and it is compared to alternatives from theory and practice all other known mechanisms are either unfair ex post or manipulable even in large markets and most are both manipulable and unfair

on the optimality of a gcc monetary union structural var common trends and common cycles evidence this paper examines the suitability of the proposed monetary union among the members of the gulf cooperation council gcc to do so we identify the underlying structural shocks that these economies are subject to and assess the extent to which the shocks are symmetric additionally we test for common trends and common business cycles among the gcc economies we find that while the transitory demand shocks are typically symmetric the permanent supply shocks are asymmetric furthermore we do not find synchronous long run and short run movements in output despite the progress that has been made in terms of integration our findings indicate that the conditions for forming a gcc monetary union have not as yet been met

incentives in the probabilistic serial mechanism abstract the probabilistic serial mechanism bogomolnaia and moulin 2001 9 is ordinally efficient but not strategy proof we study incentives in the probabilistic serial mechanism for large assignment problems we establish that for a fixed set of object types and an agent with a given expected utility function if there are sufficiently many copies of each object type then reporting ordinal preferences truthfully is a weakly dominant strategy for the agent regardless of the number of other agents and their preferences the non manipulability and the ordinal efficiency of the probabilistic serial mechanism support its implementation instead of random serial dictatorship in large assignment problems

evaluating assignment without transfers a market perspective all random assignments allocations without transfers can be considered as market outcomes with personalized prices and an equal income prices proportional across agents imply efficiency common prices lead to efficiency and envy freeness this market perspective also reveals a weakness of envy freeness

school choice impossibilities for affirmative action abstract this paper investigates the welfare effects of affirmative action policies in school choice we show that affirmative action policies can have perverse consequences specifically we demonstrate that there are market situations in which affirmative action policies inevitably hurt every minority student the purported beneficiaries under any stable matching mechanism furthermore we show that another famous mechanism the top trading cycles mechanism suffers from the same drawback

recent developments in matching with constraints in an earlier work kamada and kojima 2015 we introduced matching with constraints a two sided matching problem in which the market is subject to feasibility constraints that paper proposed and analyzed a possible solution to this problem and discussed various real market applications of our results the present paper reorganizes some of the findings from our more recent effort based on kamada and kojima 2016a b

generalized reduced form auctions a network flow approach we develop a network flow approach for characterizing interim allocation rules that can be implemented by ex post allocations our method can be used to characterize feasible interim allocations in general multi unit auctions where agents face capacity constraints both ceilings and floors applications include a variety of settings of practical interest ranging from individual and group specific capacity constraints set aside sale partnership dissolution and government license reallocation

stable marriages and search frictions stable matchings are the primary solution concept for two sided matching markets with nontransferable utility we investigate the strategic foundations of stability in a decentralized matching market towards this end we embed the standard marriage markets in a search model with random meetings we study the limit of steady state equilibria as exogenous frictions vanish the main result is that convergence of equilibrium matchings to stable matchings is guaranteed if and only if there is a unique stable matching in the underlying marriage market whenever there are multiple stable matchings sequences of equilibrium matchings converging to unstable inefficient matchings can be constructed thus vanishing frictions do not guarantee the stability and efficiency of decentralized marriage markets

international migration capital mobility and transitional dynamics much of recent thinking on the problems of the central and east european countries ceecs centres on how long it will take them to catch up to oecd economies and how various policies will hasten or hinder the transition this paper using a highly stylized framework focuses on a quite different set of issues how the nature of the transition can effect the nature of the long run equilibrium the mechanism we focus on is factor mobility and factor complementarity excerpt

revisiting the brain drain literature with insights from a dynamic general equilibrium world model the existing brain drain literature has found various mechanisms through which the high skilled south to north migration affects developing economies however some of the new found effects remain disputable due to limited evidence this study aimed to provide suggestive guidelines for future research by identifying the mechanisms that can generate larger economic impacts at the aggregate the analysis is based on a dynamic general equilibrium world model that is calibrated to published statistics and incorporates empirical estimates on the effects of brain drain it simulates short and long run impacts of increased brain drain on gdp per capita gni per capita and income inequality the results suggest that more studies should be conducted to further examine how the brain drain influences human capital formation and technology spillovers both have significant impacts on domestic production and national income a better understanding of different remitting patterns is also desirable to understand how to reduce inequality and promote recipients investment in productive assets
