the optimal mechanism for selling to a budget constrained buyer abstract this paper finds an optimal mechanism for selling a good to a buyer who may be budget constrained we consider a seller with one unit of a good facing a buyer with a quasilinear utility function if the buyer does not face a binding budget constraint textbook monopoly pricing is optimal by contrast the possibility of a binding budget constraint can make it optimal for the seller to use nonlinear pricing to commit to a declining price sequence to require the buyer to disclose his budget or to offer financing journal of economic literature classification numbers c70 d42 d45 d89 l12

non linear pricing with budget constraint abstract this paper purports to study the non linear pricing problem when a budget constraint limits the magnitude of the monetary transfer we show that distortions even affect consumers for which the constraint does not bind

expanding the solution set organizational economics and agri environmental policy abstract the market failure paradigm dominates agri environmental research and policy organizational economics provides an alternative framework for analyzing agri environmental problems and points to alternative solutions in this paper the traditional approach of creating markets for environmental goods and services is critiqued and set aside to provide space for an organizational analysis from an organizational perspective the relationship between the state and agricultural agents is viewed as grounded in an over arching exchange relationship including elements of cooperation and trust such a collaborative exchange relationship may prove useful in supporting exchange between agricultural agents and the state leading to the provision of ecological goods and services highlighting the potential of organizational economics the analysis suggests that agri environmental research and policy go further in accounting for and investigating the unique organizational modes of exchange governing the production of food fiber and ecological goods and services

the acquisition of fisher body by general motors abstract it is commonly said that in 1926 general motors was led to acquire its supplier of automobile bodies fisher body because fisher body held up general motors it is claimed that fisher body did this by locating its body plants far away from the general motors assembly plants and by adapting inefficient methods of production thus increasing both the cost of producing bidies and the profits of fisher body under its cost plus contract this tale is factually incorrect what general motors acquired in 1926 was the 40 percent of the shares of fisher body that it did not already own furthermore fisher body did not locate its plants far away from the general motors assembly plants it is also most implausible for many reasons that the fisher brothers would have used inefficient methods of production there is no evidence that a holdup occurred

the specification of dynamics in cost function and factor demand estimation this paper concerns the problem of properly specifying the dynamic structure of models of industry costs and factor demands the paper compares three common frameworks long run costs with all factors assumed in equilibrium full static equilibrium short run costs with variable factors in short run equilibrium partial static equilibrium followed by computation of long run costs and short run costs including internal capital adjustment costs partial dynamic equilibrium the approach of the paper is to estimate a capital labor fuel electricity model for six oecd countries g7 less italy for the 1960 1989 period using the three different dynamic specifications we obtain substantially different results in terms of factor demand cross price effects and technical change the implication is that proper dynamic specification is critical the partial dynamic equilibrium model appears to behave most consistently across the cross section copyright 1993 by mit press

the new institutional economics this outstanding book presents new original contributions from some of the world s leading economists including ronald coase douglass c north masahiko aoki oliver e williamson and harold demsetz it demonstrates the extent and depth of the new institutional economics research programme which is having a worldwide impact on the economics profession

trade in intermediates and the colonial pattern of trade this paper builds up a model of trade in intermediate goods and uses it to analyze certain fea tures of the colonial pattern of trade different parts of an interme diate good are traded between two nations and the intermediate good i s then used to make two country specific products the author discuss es the effects of technical progress in different sections of the pro ductive spectrum on factoral terms of trade and allocation of resourc es in each country in a three country two good colonial world it i s shown that immiserization can occur even with given commodity terms of trade copyright 1987 by the review of economic studies limited

the role of international fragmentation in the development process much of what has been written about the process of economic development has concentrated on macroeconomic factors that affect the growth process such as the community s savings rate its ability to attract foreign investment and the composition and quality of its factor endowment base less formally dealt with but nonetheless often cited as important in the development process is the nature of government regulations and the type of institutions that are reflective of the community s own cultural inheritance

asymmetric adjustment costs in simple general equilibrium models abstract this paper demonstrates that the introduction of asymmetric adjustment costs in a simple general equilibrium framework establishes a meaningful link between factor price determination and output determination breaking the analytically convenient dichotomy of the heckscher ohlin samuelson model the possibility of trade between seemingly similar countries that differ in their adjustment technologies is visited

a theory of contracts with limited enforcement we present a theory of contracts under costly enforcement in the context of a dynamic relationship between an uninformed buyer and a seller who is privately informed on his persistent cost at the outset public enforcement relies on remedies for breach private enforcement comes from severing relationships we first characterize aggregate enforcement constraints ensuring that trading partners do not breach contracts unduly whether a long term contract is enforceable does not depend on the distribution of penalties for breach between the buyer and the seller while under complete information the optimal contract would remain stationary non stationarity might arise under asymmetric information enforcement constraints are time dependent and easier to satisfy as time passes indeed a high cost seller may be tempted to trade high volumes at high prices at the beginning of the relationship before breaching the contract later on yet such take the money and run strategy becomes less attractive as time passes and can be prevented with backloaded payments the optimal contract thus goes through two different phases first quantities and prices increase at the inception of the relationship later on the contract looks more stationary the public and private sides of enforcement plays different roles in determining the length of the earlier phase of contracting long run screening distortions encapsulate the quality of enforcement offering de facto a link between the quality of the legal system and contractual performances

compositional change aggregation and dynamic factor demand estimates on a panel of manufacturing firms most empirical research on investment and dynamic factor demand has used aggregated data the large number of authors who have cited this as a source of problems strongly suggests possible benefits from analyzing individual firm data this paper presents an analysis of a panel dataset of us manufacturing firms several models based on cost minimization and a three factor cobb douglas technology are developed the differences concern whether the technology varies across two digit sic industries the presence of fixed adjustment lags and the determinants of adjustment costs identification relies on the rational expectations hypothesis and estimation on non linear 3sls the estimates indicate that versions with the adjustment lag perform better than others conditional elasticities reveal that factor demand responds rapidly to anticipated changes in output and factor prices a finding consistent with other recent work it appears that the factor demand of large firms is more price sensitive and less sensitive to output than small firms consistent with recent work on credit market imperfections comparison of the results based on the pooled and the industry varying technologies indicate that the use of aggregate data is indeed a source of problems

estimation of the internal adjustment costs model using longitudinal establishment data this paper develops estimates of the internal costs measured in terms of foregone current output associated with the introduction of new plant and equipment into manufacturing establishments using the census bureau s longitudinal establishment data file a very large and rich source of production and investment data our estimates provide strong support for the internal adjustment costs hypothesis they indicate that one dollar increases in expansion and replacement investment cause on the average 35and 21 cent reductions respectively in current output the internal cost of adjusting to equipment appears to be higher than the cost of adjusting to plant

interstate migration in mexico variations on the todaro theme abstract this study of migration in mexico is based upon a modified todaro approach and utilizes census data in a simultaneous equations model of 13 variables it is unique in several ways a it introduces proxy variables for employment probability and cost of migration that have not heretofore been found in the literature but for which data are often available b it illustrates that in some important cases census data have advantages not available through surveys and c it finds that in some sense land reform in mexico may have operated perversely finally the study opens a new avenue for the study of informal sector growth

expected revenue of all pay auctions and first price sealed bid auctions with budget constraints we show that all pay auctions dominate first price sealed bid auctions when bidders face budget constraints this ranking is explained by the fact that budget constraints bind less frequently in the all pay auctions which leads to more aggressive bidding in that format

the three faces of factor intensities abstract in this paper we suggest that factor intensities have more than one face and care must be taken in the comparisons chosen among other things we illustrate that in the multi country multi commodity case a capital abundant country s export can easily be more labor intensive than its import competing sector

r d production structure and rates of return in the u s japanese and german manufacturing sectors a non separable dynamic factor demand model abstract the focus of this paper is an analysis of the production structure the demand for factor inputs and the rates of return in the manufacturing sector of three major industrialized countries the united states japan and germany the analysis is based on a dynamic factor demand model with two variable inputs labor and materials and two quasi fixed inputs capital and rd also for all countries the speed of adjustment for capital is found to be higher than that for r d

an analysis of rural urban migration and protection in this paper a harris todaro migration model is developed with the urban manufacturing sector supplying a crucial input for the rural sector capital is region specific but flows freely between two urban sectors final goods are traded and have exogenously fixed prices if this economy imposes a tariff on the import competing manufacturing sector employment might go down even if the protected sector is labour intensive the paper describes how intersectoral linkages can play a significant role in determining the employment effects of a tariff summary in fre excerpt

revenue implications of money creation under leviathan most governments possess a monopoly franchise in the creation of money economists provide an analytical justification for this institutional arrangement either in terms of the use of monetary aggregates for macro economic stabilization or in terms of the alleged inability of competitive markets to generate tolerably efficient monetary results any complete case for the government s monetary monopoly must however depend on a comparison of market and political arrangements a comparison that requires predictions about how governments are likely to behave once a monopoly franchise is assigned similarly such predictions are crucial in evaluating restrictions that might be imposed on the government s exercise of its money creation power in designing a monetary constitution in the analysis of political arrangements the revenue implications of the money creation power are probably more significant than considerations of either macro economic stability or optimality in the money supply although those revenue implications are incidental to demonstrating the nature of market failure in monetary arrangements they are fundamental in understanding how the government might exploit a monopoly in money creation once granted our interest in the revenue effects of money creation stems from a broader study of constitutional restrictions on the revenueraising authority of government see our book the power to create money is naturally encompassed in this restrictions on the revenue raising power must embody restrictions on the power to create money consequently the fiscal constitution has important implications for the monetary constitution in this paper we examine both the revenue implications of money creation and desirable consitutional restrictions on the money creation power within the context of a specific model of political processes

monopoly with incomplete information recent theoretical research on principal agent relationships has emphasized incentive problems that arise when the parties involved are constrained by either asymmetric information or their inability to monitor each other s actions here we concentrate on the former constraint and consider the case of a single principal the monopolist the main contribution is to show that under a separability assumption strong conclusions can be drawn about the nature of optimal incentive schemes although the primary focus is on optimal quantity discounts in a monopolized market the results also shed light on related topics such as optimal income taxation and commodity bundling

trade and protection with multistage production this paper analyses trade in manuf acutured goods that are produced via a vertical production structure with many stages where some value is added at each to an intermediate product to yield a good in process ready for the next stage we consider the stage at which a good is traded to be an economically endogenous variable with comparative advantage determining the pattern of production specialization by stages across countries we study how endowment changes and policy shifts move the margin of comparative advantage which thus provides a channel for resource allocation adjustment that is additional to the usual ones of factor substitution and changes in the quantity of output

transitional dynamics in two sector models of endogenous growth the steady state and transitional dynamics of two sector models of endogenous growth are analyzed in this paper we describe necessary conditions for endogenous growth the conditions allow us to reduce the dynamics of the solution to a system with one state like and two control like variables we analyze the determinants of the long run growth rate we use the time elimination method to analyze the transitional dynamics of the models we find that there are transitions in real time if the point in time production possibility frontier is strictly concave which occurs for example if the two production functions are different or if there are decreasing point in time returns in any of the sectors we also show that if the models have a transition in real time the models are globally saddle path stable we find that the wealth or consumption smoothing effect tends to dominate the substitution or real wage effect so that the transition from relatively low levels of physical capital is carried over through high work effort rather than high savings we develop some empirical implications we show that the models predict conditional convergence in that in a cross section the growth rate is predicted to be negatively related to initial income but only after some measure of human capital is held constant thus the models are consistent with existing empirical cross country evidence authors

a simple production model in trade and its applications abstract in a simple production model some counter intuitive results are derived a increase in the relative price of good might reduce its production and reduce the absolute return to the specific factor exclusively used in this sector b uniform technical progress in two sectors might lead to a contraction in one of those sectors later other applications of such a structure are discussed

socially optimal procurement with tight budgets and rationing abstract we investigate the behaviour of a social planner that secures the supply of a good e g an environmental benefit through contracting with private agents while the social planner seeks to maximise net social benefits she is also controlled with a fixed budget private agents are profit maximising and hold private information concerning their variable costs of production they also have known fixed costs of contracting we find that budget constraints and fixed costs change the optimal contract design in more than one way the social planner minimises costs rations high cost contracts to reduce fixed costs and information rents and distorts contracts for all agent types including low cost agents we find that rationing improves social welfare also even though social costs including tax distortion are explicitly taken into consideration they do not affect the design of optimal contracts when budgets are tight in those cases the budget constraint dominates the solution

environmental regulations and the problem of sustainability moving beyond market failure abstract the standard metaphor of market failure is an impediment to the crafting of environmental policy that can escape policy lock in sustainability requires a policy process that can avoid this lock in sustainability concerns the creation of dynamic human processes that can respond to indeed anticipate unanticipated feedback from biological processes

adjustment costs production functions and capital labour substitution in greek manufacturing 1958 80 treating adjustment costs as part of the decision maker s objective function a differential system of factor demand equations is derived and estimated jointly with a ces production function using data for greek manufacturing estimates of production function parameters and adjustment cost functions are thus obtained the results show that the elasticity of substitution between capital and labour is slightly higher than one increasing or constant returns to scale exist for most manufacturing branches there is considerable technical progress of around 4 adjustment cost due to investment and employement changes are responsible for an annual loss of 8 54 of output whereas labour seems to be used inefficiently in greek manufacturing

a complete solution to a class of principal agent problems with an application to the control of a self managed firm this paper considers a class of principal agent problems which have the following features 1 there is adverse selection because the principal ignores the value of one parameter of the agent s true characteristics 2 leaving aside the information parameter the principal s welfare as well as the agent s welfare depend on two types of variables observable to both of them the first ones possibly multidimensional are called action variable s and the second one which is one dimensional has in general the meaning of a money transfer 3 the principal is a stackelberg leader of the two person game he can commit himself to decision rules which are admissible on informational grounds he optimizes within the adequate class taking into account besides the agent s reaction one constraint which has generally the meaning of an individual rationality constraint and sometimes of a feasibility constraint the optimization is limited to the class of non stochastic mechanisms 4 the problem can also receive an alternative interpretation the principal faces a continuum of agents of unknown characteristics the distribution being known however stylized principal agent problems of this type have often been considered in the economic literature in particular the reader will later be able to recognize that the standard income tax model a la mirrlees 1971 the quality or quantity choice model of the monopolist a la mussa and rosen 1978 or maskin and riley 1982 and the model of government regulation of the private monopolist of baron and myerson 1982 all belong to

the fable of fisher body abstract general motors s gm s acquisition of fisher body is the classic example of market failure in the literature on contracts and the theory of the firm according to the standard account in 1926 gm merged vertically with fisher body a maker of auto bodies because of concerns over transaction specific investment and contractual holdup that account exhibits errors of historical fact and interpretation general motors acquired a 60 percent interest in fisher body in 1919 moreover the contractual arrangements and working relationship prior to the 1926 merger exhibited trust rather than opportunism fisher body s production technology did not exhibit asset specificity the merger reflected economic considerations specific to that time not some immutable market failure we demonstrate that vertical integration was directed at improving coordination of production and inventories assuring gm of adequate supplies of auto bodies and providing gm with access to the executive talents of the fisher bro

skilled unskilled wage inequality and urban unemployment i introduction an extensive body of literature has looked at possible effects of trade liberalization on the labor market in the north the effects on the labor market in the south have not drawn as much attention conventional wisdom associated with the stolper samuelson theorem predicts a gradual reduction of skilled unskilled wage inequality in the south however recent studies on latin american countries exhibit conflicting patterns wood 1997 summarizes the empirical findings citing a series of articles by robbins 1995a 1995b 1996a 1996b that convincingly demonstrate that latin america has experienced an increasing wage gap between the skilled and the unskilled following a more open trade and investment regime while globalization induced changes in production patterns and the consequent increase in the demand for skilled labor relative to unskilled labor has often been cited as the root cause of wage inequality there has been no general agreement over the possible source of such increased demand for skilled labor the debate among economists on this has followed two broad paths one relying on technological changes and the other on trade and investment while technological change may have played a key role in the widening wage gap in the industrialized countries there is strong evidence robbins 1994a 1994b 1995a 1995b 1996a 1996b robbins and zveglich 1995 wood 1997 indicating the dominant influence of trade and investment on wage inequality in the developing economies the implications of a more open trade and investment regime need to be analyzed in terms of frameworks that explicitly take into account the structural features of labor markets in the south one of the key structural differences between the north and the south is that the south experiences a pronounced rural urban migration in the presence of urban unemployment basu 1997 ray 1998 the goal of our paper was to capture this feature within the structure of a simple general equilibrium model in an effort to understand the effect of fragmentation on the skilled unskilled wage differential and employment in the south the rest of the paper is organized as follows the next section places this paper in the context of the relevant literature section iii describes the general equilibrium model with the possibility of fragmentation and unemployment section iv compares and contrasts the impact of trade and endowment on the skilled unskilled wage gap and employment with and without fragmentation section v concludes ii context the motivation of this paper stems from our view that the southern experience does not necessarily contradict conventional wisdom as has been claimed in wood 1997 but points to the need for parsimonious yet meaningful modifications of the structure of general equilibrium models from which the wisdom is derived to properly reflect the salient structural features of the south on the one hand production fragmentation has become an important facet of globalization in modern times 1 sharp declines in transportation and communication costs have encouraged this process of slicing the value chain that is evident in international trade data this has been sustained by various regional integration agreements that have reduced the barriers to international trade and investment as well as important technical innovations in telecommunications and information technology that have facilitated the coordination of international production networks this advanced stage in the international division of the chain of production has brought a fundamental change in the nature of international trade as goods increasingly cross multiple national borders while they are in process several authors such as jones kierzkowski and lurong 2005 wan 2005 long 2005 jones and kierzkowski 1998 jones and marjit 2001 arndt 1998 feenstra 1998 harris 1998 hummels rapoport and yi 1998 feenstra and hanson 1996b and dixit and grossman 1982 have analyzed the role of fragmentation in world trade

creating holdup through vertical integration fisher body revisited abstract general motors s gm s 1926 acquisition of fisher body has long served as a cornerstone of hold up arguments for vertical integration this paper utilizes primary historical evidence to make three related claims first it shows that gm s initial investment in fisher body occurred primarily to gain access to the fisher brothers specialized human assets second it shows that holdup was not the cause of gm s purchase of fisher body instead the primary factors leading to vertical integration were gm management s fears over the fisher brothers impending departure coupled with problems of financing new body plants finally i show that while holdup was not an issue prior to integration the fisher brothers successfully held up gm after they became employees far from reducing opportunistic behavior vertical integration increased gm s vulnerability to rent seeking behavior based in human asset specificity

will farmers trade profits for stewardship heterogeneous motivations for farm practice selection we investigate the trade off agricultural producers face between profits and stewardly activities when selecting farm practices instead of the profit maximization framework we model producer behavior in an expanded utility framework built on production technology and including two utility components self and social interests the framework introduces inherent heterogeneity and social environmental motivations into farmer behavior based on this model we hypothesize that there are farmers that are willing to forego some profit to engage in stewardly farm practices with an empirical study we provide evidence that some farmers are willing to make this sacrifice results are consistent with the multi utility hypothesis

dynamic factor demands under rational expectations we model the industrial demands for structures equipment and blue and white collar labor in a manner consistent with rational expectations and stochastic dynamic optimization in the presence of adjustment costs but allowing generality of functional form we represent the technology by a translog input requirement function that specifies the amount of blue collar labor needed to produce an output level given quantities of three quasi fixed factors nonproduction workers equipment and structures a complete description of the production structure is obtained by simultaneously estimating the input requirement function and three stochastic euler equations we find adjustment costs are small in total but large on the margin and differ considerably across factors

economic reform and informal wage a general equilibrium analysis abstract we attempt to trace the consequences of liberal economic policies on informal wage in a general equilibrium model with formal informal labor markets wage differential vertical linkage and restricted capital movement in particular we show that the informal wage representing income for a vast segment of unskilled labor may actually increase even if more people are employed in the informal segment this also confirms that a contraction in the formal sector employment and the consequent expansion in the informal segment do not necessarily imply impoverishment of the existing set of informal workers

organizational economics in agriculture policy analysis the ongoing industrialization of u s agriculture encompasses important changes in farm production practices in the organization of farm input and output markets and in the mix of activities carried out by farm operators these shifts raise important issues for the role of government in the sector and for the design of research and data programs to support public policy analysis basic frameworks of organizational economics in particular concepts from principal agent models organizational design and transaction costs have direct applications in addressing these issues 1 while organizational economics has been used in some areas of policy analysis the concepts are underutilized in other areas industrialization encompasses four important organizational shifts to more differentiated food products to more explicitly coordinated production and marketing channels such as contracts to expanded use by farmers of leasing arrangements alliances and service purchases and to increased farm sizes these shifts are the most prominent organizational responses to an underlying collection of causal forces at play including the mechanical chemical and biological innovations that drove twentieth century advances in agricultural productivity as well as more recent information and biotechnology advances the forces underlying agricultural industrialization affect the design and impact of and support for various public policies in agriculture policy has long encompassed commodity programs designed to support farm household incomes and manage supplies market

globalization outsourcing and wage inequality there is considerable debate over whether international trade has contributed to the declining economic fortunes of less skilled workers one issue that has become lost in the current discussion is how firms respond to import competition and how these responses in turn are transmitted to the labor market in previous work we have argued that outsourcing by which we mean the import of intermediate inputs by domestic firms has contributed to an increase in the relative demand for skilled labor in the united states if firms respond to import competition from low wage countries by moving non skill intensive activities abroad then trade will shift employment towards skilled workers within industries in this paper we extend our previous work by combining new import data from the revised nber trade database with disaggregated data on input purchases from the census of manufactures we construct industry by industry estimates of outsourcing for the period 1972 1990 and reexamine whether outsourcing has contributed to an increase in relative demand for skilled labor our main finding is that outsourcing can account for 31 51 of the increase in the relative demand for skilled labor that occurred in u s manufacturing industries during the 1980s compared to our previous estimate of 15 33 this abstract was borrowed from another version of this item

optimum taxation and public production in a dynamic harris todaro world abstract this paper examines the steady state dynamics and develops policy rules in a two sector optimum growth model with urban unemployment people migrate from the rural sector to the urban sector in response to a difference between the minimum expected urban wage and the actual rural wage labor in the urban sector is heterogeneous and the skilled labor force owns the capital stock in both sectors as well as the land in the rural sector the government taxes urban wages capital income from both sectors and the income from land and invests in the two sectors

sector specific minimum wages economic growth and some policy implications abstract economic growth is introduced in the urban unemployment model of harris and todaro it is shown that in the steady state the optimal savings ratio is greater than the golden rule savings ratio under full employment also the optimal proportion of total investment allocated to the urban sector is not necessarily higher than the optimal proportion under full employment

agri environmental policies in the eu and united states a comparison abstract agri environmental policies aeps in the united states and the european union are examples of payments for environmental services that pay farmers to reduce the negative externalities of agricultural production while serving as a means to transfer public funds to farmers we show that despite similar origins aeps in the two regions differ both in their specific objectives and in their implementation for example aeps in most member states of the eu 15 have the additional objective of using agriculture as a driver for rural development this objective is achieved by compensating farmers for the private delivery of positive public goods such as attractive landscapes produced by agriculture the rationale is market failure and there is empirical evidence that europeans are willing to pay for such positive externalities no comparable provision exists in u s policy by contrast u s aeps focus almost entirely on reducing agriculture s negative externalities such as soil erosion second we find that u s programs are more targeted than their eu counterparts and take opportunity cost into account the eu programs on the other hand address a wider range of externalities and are focused more on the paying for a particular farming process than reducing specific negative externalities the eu takes a broader view of aeps than does the united states both in terms of type of activity that can be funded and by using less targeting by land characteristics and so the european program could be more easily used as a mechanism for transferring income to producers despite this we find evidence that many of the amenities targeted by the programs are demanded by the population

money and price posting under private information abstract we study price posting with undirected search in a search theoretic monetary model with divisible money and divisible goods ex ante homogeneous buyers experience match specific preference shocks in bilateral trades the shocks follow a continuous uniform distribution and the realizations of the shocks are private information we show that there exists a unique monetary equilibrium for generic values of the inflation rate in equilibrium each seller posts a continuous pricing schedule that exhibits quantity discounts buyers may spend nothing a fraction or all of their money holdings depending on their preference shock realizations inflation reduces the extent of non linear pricing the model captures the hot potato effect of inflation along both the extensive margin as an increase in the trading probability and the intensive margin as higher fractions of money being spent

adjustment costs and factor demands in canadian manufacturing industries the question of whether regional disparities in canada could arise as a result of nonconstant returns to scale and non identical production functions is examined this is accomplished by estimating and comparing the decision rules for factor demands across canadian regions the decision rules are based on a flexible and dynamic production technology which allows for the presence of internal adjustment costs do not impose constant returns to scale or require hours and workers to have the same output elasticities the model is estimated for four separate canadian regions ontario quebec the western and eastern provinces on annual data ranging from 1965 to 1985

possibility or impossibility of paradoxes in the small country harris todaro framework a unifying analysis abstract in this paper we argue that the harris todaro ht framework sometimes satisfies an envelope property which makes it work like a full employment heckscher ohlin samuelson hos model then the ht structure produces very similar results as one gets in the standard hos framework differences arise because the envelope condition may break down we show how several celebrated results in the ht structure can have this reinterpretation
