on the simple economics of advertising marketing and product design we propose a framework for analyzing transformations of demand such transformations frequently stem from changes in the dispersion of consumers valuations which lead to rotations of the demand curve in many settings profits are a u shaped function of dispersion high dispersion is complemented by niche production and low dispersion is complemented by mass market supply we investigate numerous applications including product design advertising marketing and sales advice and the construction of quality differentiated product lines we also suggest a new taxonomy of advertising distinguishing between hype which shifts demand and real information which rotates demand

the economics of two sided markets at a local best buy a child places a new sony playstation 3 on the cashier s counter while the parents dig out their visa card the gaming system and the payment card may appear to have little connection other than this purchase however these two items share an important characteristic that is generating a series of economic insights and has important implications for strategic decision making and economic policymaking both video game systems and payment cards are examples of two sided markets broadly speaking a two sided market is one in which 1 two sets of agents interact through an intermediary or platform and 2 the decisions of each set of agents affects the outcomes of the other set of agents typically through an externality in the case of a video game system the intermediary is the console producer sony in the scenario above while the two sets of agents are consumers and video game developers neither consumers nor game developers will be interested in the playstation if the other party is not similarly a successful payment card requires both consumer usage and merchant acceptance where both consumers and merchants value each others participation many more products fit into this paradigm such as search engines newspapers and almost any advertisersupported media examples in which consumers often negatively value rather than positively value the participation of the other side as well as most software or title based operating systems and consumer electronics malls which seek retailers and consumers convention organizers which seek buyers and sellers dating services which seek men and women and the journal of economic perspectives which seeks content and readership all experience the economics of two sided markets the multi sided nature of many internet and high technology markets as well as

tourism welfare and de industrialization in a small open economy this paper investigates the effects of an expansion of tourism on welfare output and factor prices in the host country using a general equilibrium international trade model in the absence of taxes foreign ownership and distortions an increase in foreign visitors will increase welfare only if the price of nontradables increases factor mobility and foreign ownership tend to reduce the gains from tourism while commodity taxes tend to increase them conditions under which an increase in tourism can lead to deindustrialization are also discussed copyright 1991 by the london school of economics and political science

immigrant specificity and the relationship between trade and immigration theory and evidence studies routinely document that immigrant employment concentrates in non traded goods sectors and that many immigrants have low inter sectoral mobility we consider these observed characteristics of immigrant employment with regard to the question of how immigration affects a nation s pattern of production and trade we model an economy producing three goods one is non traded domestic labor and capital are domestically mobile but internationally immobile allowing that some new immigrants will become specific to the non traded goods sector the model indicates that the effects of immigration on output and trade depend importantly on the sectoral pattern of employment of both new and existing immigrants empirical investigation in a panel data set of oecd countries supports the model s prediction that immigration raises the output of non traded goods consistent with the model we also find that immigration and trade are complements given its empirical support the model s implications for immigration policy are then discussed

agricultural productivity and structural transformation evidence from brazil we study the eects of the adoption of new agricultural technologies on structural transfor mation to guide empirical work we present a simple model where the eect of agricultural productivity on industrial development depends on the factor bias of technical change we test the predictions of the model by studying the introduction of genetically engineered soybean seeds in brazil which had heterogeneous eects on agricultural productivity across areas with dierent soil and weather characteristics we nd that technical change in soy production was strongly labor saving and lead to industrial growth as predicted by the model

structural adjustment and the construction sector abstract this paper adds a construction sector to a dynamic dependent economy model equipped with consumer tradeables and non tradeables sectors the model is used to study the response of the production structure relative prices and the trade balance to a favorable terms of trade shock under the benchmark assumptions of perfect intersectoral factor mobility a perfect international capital market and no adjustment costs for realistic relative capital intensities the model predicts a boom in the construction and consumer non tradeables sectors a contraction of the tradeables sector and no relative price changes the implications of relaxing those benchmark assumptions are discussed separately

platform competition in two sided markets many if not most markets with network externalities are two sided to succeed platforms in industries such as software portals and media payment systems and the internet must get both sides of the market on board accordingly platforms devote much attention to their business model that is to how they court each side while making money overall this paper builds a model of platform competition with two sided markets it unveils the determinants of price allocation and end user surplus for different governance structures profit maximizing platforms and not for profit joint undertakings and compares the outcomes with those under an integrated monopolist and a ramsey planner jel l5 l82 l86 l96

absorbing a windfall of foreign exchange dutch disease dynamics abstract the permanent income rule is seldom the optimal response to a windfall of foreign exchange such as that from a resource discovery absorptive capacity constraints require domestic investment and investment in structures requires non traded inputs the supply of which is constrained by the initial capital stock this particularly when combined with intra sectoral capital immobility delays adjustment and creates short run dutch disease symptoms as the real exchange rate sharply appreciates and overshoots its long run value optimal revenue management requires investing in the domestic non traded goods sector and a slow build up of consumption accumulation of foreign assets adjusts to accommodate the time paths of domestic consumption and investment

the effects of mongolia s booming mining industry on its agricultural sector a test for dutch disease dutch disease occurs when currency strengthening associated with a booming sector of an economy crowds out a lagging trade dependent sector in this study a keynesian style model is specified to deduce hypotheses about how increased foreign direct investment fdi aimed at mongolia s mining sector affects its agricultural sector a key finding is that while econometric results suggest the increased fdi strengthened mongolia s currency its adverse effect on mongolia s trade sensitive agricultural sector is not sufficiently strong to cause the sector to decline although dutch disease was not detected the posited mechanism clearly is important specifically when currency strengthening is ignored the reduced form elasticity of agricultural value added with respect to fdi is 2 7 times larger than when currency strengthening is taken into account 0 103 vs 0 038 also fdi induced currency strengthening causes the keynesian multiplier y g to drop from 2 40 to 2 00 and the fdi multiplier y fdi to drop from 3 05 to 1 89

resource curse or not a question of appropriability this thesis presents three self contained essays focusing on empirical questions in growth and development economics each article addresses specific questions on why countries perform differently in particular i analyse the effect of democracy on economic development the relationship between natural resources and growth and the efficiency of foreign development assistance in the first essay democracy consolidation and growth i analyse the effect of democracy on economic growth in this context i argue that an important aspect to consider is how consolidated political systems are put simply i find that it is not only a question of how democratic countries are but also how long they have been democratic in other words economic performance tends to improve with the duration of uninterrupted democracy the performance of autocracies on the other hand tends to deteriorate over time however for newly established political systems there seems to be a cost of being democratic this implies that democracies only bear their fruit after some time the analysis has important policy implications to overcome initial straits international assistance focused on democratic consolidation may be important and a very good investment in fostering long run development the second essay resource curse or not a question of appropriability together with anne boschini and jesper roine is concerned with the relation between natural resources and economic development for most laymen as well as for most economists it would seem reasonable that countries richly endowed in natural resources also benefit from this wealth however a large literature has found a systematic negative effect of natural resource abundance on economic growth we suggest that this so called resource curse is not determined by resource endowments alone but rather by the interaction between the type of resources a country possesses and the quality of institutions in the country this combination of factors determines what we call the appropriability of a resource the concept of appropriability captures the likelihood of natural resources leading to rentseeking corruption or conflicts which in turn will harm economic development our results suggest that if institutions are good enough the curse may be turned into a blessing this may explain why some countries such as norway and botswana tend to benefit from their resources while others such as angola and sierra leone do not the third and final essay of this thesis foreign sectoral aid fungibility growth and poverty reduction is a contribution to the aid efficiency literature which is concerned with the question of whether aid helps or hinders economic development foreign development assistance is often targeted on specific public expenditure sectors if this aid is not used in the sector for which it was granted e g health education it is said to be fungible and donors may end up financing something completely different from what they intended e g military expenditures the major concern about sectoral fungibility is that the alternative use of aid may be less productive or less socially useful however measuring fungibility is not sufficient to determine whether foreign sectoral aid fungibility is actually harmful what is important is how the funds treated as fungible are used the essay starts by obtaining estimates of fungibility for 57 countries the results suggest that sectoral aid is indeed largely treated as fungible by recipient countries next to assess the economic and health effects of fungibility these estimates are incorporated into an empirical model of aid and growth as well as into a model of aid and infant mortality altogether i find no evidence of more fungible sectoral aid leading to worse performance

intrinsic motivation and incentives workers act in the interests of their employ ers for a host of reasons sometimes money is the motivation but often it is because they care about what they do despite the importance of such intrinsic motivation the economic litera ture has offered little in terms of understanding relevant trade offs when alignment of inherent preferences rather than monetary interests is what motivates people 1 instead the literature has focused largely on the efficiency gains that arise from agents sharing the preferences of their employers 2 this paper offers such a theory of intrinsic motivation where firms partially solve agency problems by hiring agents with particu lar preferences unlike the previous literature i show that firms in general hire agents who do not share their interests instead agents are disproportionately motivated to carry out a sub set of what the firm cares about specifically i show that the institution hires the agent with similar preferences to himself only in the limit ing case where the agent s preferences are irrel evant namely when output can be perfectly contracted on instead the optimal response of the institution is to hire biased agents with the degree of bias increasing as contracting mea sures get worse the reason for this is rather simple that jobs within firms are specialized so for example some people make things others design them yet other sell them and so on similarly aca demics do research deans raise money admin istrators do the books social workers provide services to clients while their superiors are charged with cost control etc the principal novelty of this paper is to show how hiring practices and specifically the intrinsic moti vation of those hired changes as the ability to contract worsens in a world where tasks are specialized in doing so it paints a picture of firms responding to noncontractibility by hiring agents with very extreme interests at the cost of their ignoring other aspects of their jobs so for example if the output of a social worker cannot be measured a natural response will be to hire agents who are highly motivated to get benefits to clients at the cost of their ignoring things like cost control simple though this observation is it illustrates a cost to using intrinsic motiva tion namely the endogenous hiring of those who increasingly care only about one aspect of their job in this way the simple model outlined here lays the foundation for a view of poor contracting firms as fiefdoms where those with extreme competing interests reside a point i elaborate on elsewhere prendergast 2008 for a theory of intrinsic motivation to be use ful firms must have some control over it the central assumption here is that firms have some ability to hire employees based on these intrin sic preferences i build a model of an institution that carries out two activities say service pro vision and cost control it employs two agents to do so the tasks are somewhat specialized in that one agent primarily but not exclusively does service provision and the other primarily does cost control the institution has an objec tive that trades off these two components and has a performance measure that can reward agents the firm also chooses whom to hire potential discussant robert gibbons massachusetts institute of technology

business cycles in an oil economy abstract the recent oil price fall has created concern among policy makers regarding the consequences of terms of trade shocks for resource rich countries this concern is not a minor one the world s commodity exporters combined are responsible for 15 20 of global value added we develop and estimate a two country new keynesian model in order to quantify the importance of oil price shocks for norway a large prototype petroleum exporter domestic supply chains link mainland non oil norway to the off shore oil industry while fiscal authorities accumulate income in a sovereign wealth fund oil prices and the international business cycle are jointly determined abroad these features allow us to disentangle the structural sources of oil price fluctuations and how they affect mainland norway the estimated model provides three key results first oil price movements represent an important source of macroeconomic volatility in mainland norway second while no two shocks cause the same dynamics conventional trade channels make an economically less significant difference for the transmission of global shocks to the oil exporter than to oil importers third the domestic oil industry s supply chain is an important transmission mechanism for oil price movements while the prevailing fiscal regime provides substantial protection against external shocks

the effects of oil price shocks on the iranian economy abstract the iranian economy is highly vulnerable to oil price fluctuations this paper analyzes the dynamic relationship between oil price shocks and major macroeconomic variables in iran by applying a var approach the study points out the asymmetric effects of oil price shocks for instance positive as well as negative oil price shocks significantly increase inflation we find a strong positive relationship between positive oil price changes and industrial output growth unexpectedly we can only identify a marginal impact of oil price fluctuations on real government expenditures furthermore we observe the dutch disease syndrome through significant real effective exchange rate appreciation

motivations monitoring technologies and pay for performance monitoring technologies and pay for performance pfp contracts are becoming popular solutions to improve public services delivery their track record is however mixed to show why this may be the case this paper develops a principal agent model where agents motivations vary and so the effectiveness of monitoring technologies in such a set up it shows that i monitoring technologies should be introduced only if agents motivations are poor ii optimal pfp contracts are non linear non monotonic in agents motivations and monitoring effectiveness iii investments aimed at improving agents motivations and monitoring quality are substitutes when agents are motivated complements otherwise iv if the agents type is private information the more and less motivated agents could be separated through a menu of pfp non pfp contracts designed in a way that only the less motivated ones choose the pfp

policy adjustments to the oil boom and their evaluation the dutch disease in indonesia abstract this paper analyzes the effects of two policy adjustments namely exchange rate devaluation and the accumulation of budget surpluses to the oil export boom in indonesia by using a simple simulation model our results indicate that exchange rate adjustment had a significant impact on expansion of tradable sectors especially the manufacturing sector by reversing the real exchange rate while officially maintaining the balanced budget principle the government exercised delicate operations whereby the budget surpluses were covertly accumulated as government deposits such operations were executed as a necessary demand management policy to ensure that the effect of devaluation was persistent these policy adjustments were consistent from a macroeconomic management point of view and have contributed to avoiding the dutch disease that indonesia otherwise might have suffered because of its oil bonanza

dutch disease government policy and import demand in nigeria the effects of sectoral changes and government policies on import demand in nigeria are examined in the context of the oil shocks of the 1970s and 1980s a two equation model is estimated to determine real import demand and the real exchange rate the results show that import demand increased significantly in response to the boom induced squeeze on the agricultural sector furthermore by inducing and sustaining real exchange rate overvaluation expansionary government policies contributed to higher import demand even after the collapse in oil prices

tying and freebies in two sided markets abstract in two sided markets where platforms are constrained to set non negative prices tying can be deployed by platforms as a tool to introduce implicit subsidies for a monopoly this raises participation and benefits consumers on both sides in a duopoly tying on one side makes a platform more or less competitive on the other side depending on externalities tying may not be ex ante optimal while the competing platform may benefit from it the impact on consumers surplus depends on whether competition is softened or intensified on the profitable side moreover tying increases total welfare if network effects are strong

chicken and egg competition among intermediation service providers we analyze a model of imperfect price competition between intermediation service providers we insist on features that are relevant for informational intermediation via the internet the presence of indirect network externalities the possibility of using the nonexclusive services of several intermediaries and the widespread practice of price discrimination based on users identity and on usage efficient market structures emerge in equilibrium as well as some specific form of inefficient structures intermediaries have incentives to propose non exclusive services as this moderates competition and allows them to exert market power we analyze in detail the pricing and business strategies followed by intermediation services providers copyright 2003 by the rand corporation

gender awareness in modeling structural adjustment abstract the macroeconomic models underpinning the design of structural adjustment programs are gender blind this paper discusses strategies for introducing gender analysis into these models and evaluates the strengths and weaknesses of the models from a gender perspective it concludes that besides being blind to gender the models are also blind to the waste of resources and impoverishment that stems from deficient aggregate demand undemocratic decision making and directly unproductive expenditures that buttress male power this waste is however likely to be diminished by moves to more egalitarian systems of gender relations entailing changes in the structure of entitlements and the social matrix in which macroeconomic processes are embedded

information management and pricing in platform markets we study platform markets in which the information about users preferences is dispersed first we show how the dispersion of information introduces idiosyncratic uncertainty about participation decisions and how the latter shapes the elasticity of the demands and the equilibrium prices we then study the effects on profits consumer surplus and welfare of platform design blogs forums conferences advertising campaigns post launch disclosures and other information management policies affecting the agents ability to predict participation decisions on the other side of the market

differentiated networks equilibrium and efficiency we consider a model of price competition in a duopoly with product differentiation and network effects the value of a good for a consumer is the sum of a common and an idiosyncratic component the first captures the vertical dimension of quality the second captures horizontal differentiation each consumer privately observes his own value for each good but cannot separate the common and the idiosyncratic component therefore he has incomplete information about the value of the goods for the other consumers after firms announce prices consumers choose simultaneously which network to join facing a coordination problem in the efficient allocation both networks are active and the firm with the highest expected quality has the largest market share to characterize the equilibrium allocation we derive necessary and sufficient conditions for uniqueness of the equilibrium of the coordination game played by consumers for given prices the equilibrium allocation differs from the efficient one for two reasons first the equilibrium allocation of consumers to the networks is too balanced since consumers fail to internalize network externalities second if access to the networks is priced by strategic firms then the product with the highest expected quality is also the most expensive this further reduces the asymmetry between market shares and therefore social welfare

multidimensional platform design successful platforms attract not just many users but also those of the right kind the right kind of user is one who can either be directly monetized or who differentially attracts other valuable users bonacich centrality on the network of user sorting with direct value of monetization captures this feedback loop and thus characterizes the value of user characteristics we use this value to determine optimal steady state platform design and reliable means for platforms to reach such a steady state we apply these results respectively to explain the dynamic growth strategy of social networks and urban development policies of cities

the impact of macroeconomic adjustment on poverty in the presence of wage rigidities abstract the paper examines the effects of macro economic policy on poverty when the labour market is subject to partial wage rigidity it shows that the orothodox assumption of a perfect labour market ignores a number of important conflicts arising from macro economic policy specifically it demonstrates that an expenditure switching policy will have greater adverse effects on the formal sector compared with the informal sector and this has implications for poverty under reasonable assumptions about the incidence of poverty in these sectors the paper suggests that more confident predictions about poverty outcomes are possible although in the last analysis theoretical ambiguity is always present whether the rigid wage case gives significantly different predictions from the orthodox model is shown to depend critically on the poverty level among the unemployed if this is similar to that found in the formal sector the difference between the two models is only quantitatively important when the share of formal sector employment is large in this case the rigid wage model indicates less favourable poverty outcomes however if poverty levels are high among the unemployed the rigid wage model predicts more favourable effects

commodity price volatility with endogenous natural resources abstract natural resource reserves are exogenous in models of small commodity exporters changes in the stock of reserves play no role in the macroeconomy including in business cycle volatility trade dynamics or exchange rate volatility we consider richer supply dynamics and model exploration and depletion we show that an endogenous supply of reserves is important for capturing the stylised facts associated with commodity price shocks including a commodity currency the crowding out of non commodity activity dutch disease and a volatile business cycle we also consider how exploration and depletion affect the ranking of optimal monetary and taxation policies when natural resource reserves are held fixed monetary policy is an efficient tool for stabilising the effects of commodity price shocks however when exploration and depletion are accounted for using interest rates to stabilise the effects of commodity price changes becomes inefficient using taxes on the resource sector specifically an ad valorem royalty remains efficient

external disturbances domestic policy responses and debt accumulation in nigeria abstract this paper provides a case study of the link between external shocks domestic policy responses and external debt accumulation in nigeria the indonesian experience during 1970 1989 is provided as a contrast for policy comparison a significant part of the increase in external debt in the two countries corresponds to financing of capital flight after 1981 current account deficits assumed greater importance in the accumulation of external debt the growth in external debt was caused in part by adverse external conditions the results of this study show that the nigerian debt crisis was exacerbated by inappropriate policy responses indonesia avoided a crisis by applying prudent real exchange rate management and fiscal restraint

supplying information to facilitate price discrimination the authors examine the incentive of a seller to allow potential buyers to acquire private information about their tastes for the seller s product improved private information for buyers enables the seller to segment the market and charge higher prices to high value buyers however improved information can also provide rents to buyers in a variety of settings this tradeoff is optimally resolved at one of two extremes either buyers are supplied with the best available knowledge of their tastes or no information is supplied by the seller copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the provision of incentives in firms i ncentives are the essence of economics despite many wide ranging claims about their supposed importance there has been little empirical assessment of incentive provision for workers the purpose of this paper is to critically overview existing work on the provision of incentives since the interests of workers and their employers are not always aligned a large theoretical literature has emphasized how firms design compensation contracts to induce employees to operate in the firm s interest this literature has reached into many areas of compensation and has pointed to a multitude of different mechanisms that can be used to induce workers to act in the interests of their employers these include piece rates options discretionary bonuses promotions profit sharing efficiency wages deferred compensation and so on my objective here is to evaluate this literature in the light of a growing empirical literature on compensation where possible i will address the literature from two perspectives first an underlying assumption of this literature is that individuals respond to contracts that reward performance accordingly i consider whether agents behave in this way and whether these responses are always in the firm s interest second i address whether firms write contracts with these responses in mind in other words do contracts look like the predictions of the theory incentives are provided to workers

industrial policy and exchange rate scepticism the aim of the present paper is to put in historical perspective the development thinking on the relationship between industrial and exchange rate policies the first section focuses on the thought of the so called pioneers of development economics specifically their preference for protectionism and their belated recognition that an exchange rate policy could act as a substitute to it in the second one we analyze the exchange rate skepticism that arises out of the theories that identify a foreign constraint to growth in addition to the one revealed by the pioneers the third section briefly complements the previous discussion with reference to macroeconomic formulations that allow for short run contractionary effects of a devaluation reinforcing the skepticism in question in the fourth section we discuss the revival of development thinking in the 1980s and its discussion about east asian trajectories a literature that placed great emphasis on industrial policy finally in the fifth section we discuss the new historical facts and the new development macroeconomics models that are putting an end to exchange rate skepticism

tying foreclosure and exclusion in recent years the leverage theory of tied good sales has faced heavy and influential criticism in an important sense though the models used by its critics are actually incapable of addressing the leverage theory s central concerns here the author reconsiders the leverage hypothesis and argues that tying can indeed serve as a mechanism for leveraging market power the mechanism through which this leverage occurs its profitability and its welfare implications are discussed in detail copyright 1990 by american economic association

south african manufacturing industries catching up or falling behind this article argues that intra industry trade with developed countries is an important source of technology transfer south africa has an industrial structure that is suited to such trade but high costs and weak social capacity to assimilate new technology therefore reintegration into the world economy is likely to reinforce dependence on resource intensive industries in the short run this need not adversely affect economic growth but unless the quality and quantity of education and training are improved the prospects for rebuilding the technological capacity and catch up with oecd countries are bleak

the narrow moving band the dutch disease and the competitive consequences of mrs thatcher notes on trade in the presence of dynamic scale economies abstract this paper presents a model of trade in which comparative advantage instead of being determined by underlying attributes of countries evolves over time through learning by doing in this model arbitrary patterns of specialization once established tend to become entrenched over time the model sheds light on three widely held views that do not make sense in more conventional models first is the view that temporary protection of selected sectors can permanently alter the pattern of comparative advantage in the protecting country s favor second is the view that seemingly favorable developments such as the discovery of exportable natural resources may lead to a permanent loss of other sectors and reduce welfare in the long run third is the possibility that a temporary overvaluation of a currency due to tight money can lead to a permanent loss of competitiveness in some sectors

aid the real exchange rate and why policy matters the cases of morocco and tunisia abstractevery form of foreign exchange inflow including aid can potentially cause real exchange rate appreciation with adverse consequences for the production of tradables dutch disease whether it does so depends on the policy response to the inflow this paper investigates the issue for morocco and tunisia over 1980 2009 we find that aid led to a real appreciation in morocco but had no effect on tunisia s real exchange rate this confirms the importance of the macroeconomic framework in which aid is provided and the key role for infrastructure and other supply side improvements in determining the final real economy impact of aid and other inflows

stolper samuelson rybczynski in the pacific real wages and real exchange rates in the philippines 1956 1978 abstract the paper attempts to explain movements of real wages in the philippines in terms of the standard trade theoretic stolper samuelson rybczynski model in view of the factor intensities in the philippines commodities are aggregated into two composite goods traded and non traded whose relative price the so called real exchange rate is shown to have been an important determinant with changes in relative factor supplies of less importance in determining real wages a conventional two sector model is set out which distinguishes between the short and long run effects in terms of the quasi fixity of sector specific capital a simple regression model is estimated and seems to provide a fairly good explanation of what has hitherto appeared to be a puzzling feature of post war philippines economic performance high growth rates of output and employment accompanied by declining real wages in turn being associated with a rising incidence of poverty in at least two periods

the varieties of resource experience natural resource export structures and the political economy of economic growth many oil mineral and plantation crop based economies experienced a substantial deceleration in growth following the commodity boom and bust of the 1970s and early 1980s this article illustrates how countries dependent on point source natural resources those extracted from a narrow geographic or economic base such as oil and minerals and plantation crops are predisposed to heightened economic and social divisions and weakened institutional capacity this in turn impedes their ability to respond effectively to shocks which previous studies have shown to be essential for sustaining rising levels of prosperity analysis of data on classifications of export structure controlling for a wide array of other potential determinants of governance shows that point source and coffee and cocoa exporting countries do relatively poorly across an array of governance indicators these governance effects are not associated simply with being a natural resource exporter countries with natural resource exports that are diffuse relying primarily on livestock and agricultural produce from small family farms do not show the same strong effects and have had more robust growth recoveries

endogenous growth with a limited fossil fuel extraction capacity campbell 1980 and following authors have discussed a limited resource extraction capacity as an augmentation of the well known hotelling model we integrate a limited extraction capacity and related investments in the endogenous growth model of tsur and zemel 2005 to study its effect on economic development the capacity constraint gives rise to three effects on the one hand higher energy costs and the reallocation of production towards capacity investments decrease production available for consumption research and or capital investments energy costs and reallocation effect on the other hand research investments may increase which boosts available production research effect depending on the capital endowment and the strength of the effects long run consumption may be boosted or depressed in particular the capacity constraint may render everlasting consumption growth non optimal in a resource rich economy furthermore we find that capacity investments may be postponed to later points in time if the capital endowment is high

three way complementarities performance pay human resource analytics and information technology we test for three way complementarities among information technology it performance pay and human resource hr analytics practices we develop a principal agent model examining how these practices work together as an incentive system that produces a larger productivity premium when the practices are implemented in concert rather than separately we assess our model by combining fine grained data on human capital management hcm software adoption over 11 years with detailed survey data on incentive systems and hr analytics practices for 189 firms we find that the adoption of hcm software is greatest in firms that have also adopted performance pay and hr analytics practices furthermore hcm adoption is associated with a large productivity premium when it is implemented as a system of organizational incentives but has less benefit when adopted in isolation the system of three way complements produces disproportionately greater benefits than pairwise interactions highlighting the importance of including all three complements productivity increases significantly when the hcm systems go live but not when they are purchased which can be years earlier this helps rule out reverse causality as an explanation for our findings this paper was accepted by sandra slaughter information systems

commodity currencies and the real exchange rate abstract this paper shows that a change in the terms of trade of a commodity exporting country could cause the relative price of nontraded goods to rise or fall depending on the strength of income and substitution effects

the effects of a natural gas boom on employment and income in colorado texas and wyoming improvements in technology have made it profitable to tap unconventional gas reservoirs in relatively impermeable shale and sandstone deposits which are spread throughout the u s mostly in rural areas proponents of gas drilling point to the activity s local economic benefits yet no empirical studies have systematically documented the magnitude or distribution of economic gains i estimate these gains for counties in colorado texas and wyoming three states where natural gas production expanded substantially since the late 1990s i find that a large increase in the value of gas production caused modest increases in employment wage and salary income and median household income the results suggest that each million dollars in gas production created 2 35 jobs in the county of production which led to an annualized increase in employment that was 1 5 of the pre boom level for the average gas boom county comparisons show that ex ante estimates of the number of jobs created by developing the fayetteville and marcellus shale gas formations may have been too large

sectoral conflict over stabilisation policies in small open economies a small open economy is characterized by a two sector model with tradables and non tradables stabilization policies typically have unequal effects on these two sectors and expansion of total output often requires contraction in one sector such situations make difficult obtaining effective consensus on the appropriate stabilization policy expansionary fiscal policy requires a contraction in one sector after the labour market adjusts to the disturbance monetary policy is ineffective under fixed exchange rates and may not have sectoral conflict under flexible exchange rates sectoral conflict can be eliminated by designing policy combinations that maintain a given relative price of nontradables this abstract was borrowed from another version of this item

oil and women a re examination abstract in a seminal article ross 2008 reports a negative correlation between oil production and women s representation in the labour force and politics across countries this article re examines these relationships exploiting variations in oil endowments to address endogeneity concerns we confirm that oil production causes decline in women s representation additionally we show that consistent with dutch disease effects oil production decreases women s employment in the traded sector however it also leads to an increase in women s employment in the nontraded sector we explore some social consequences of oil production and show that it results in women marrying earlier and having more children

two sided markets a progress report the paper provides a road map to the burgeoning literature on two sided markets and presents new results it identifies two sided markets with markets in which the structure and not only the level of prices charged by platforms matters the failure of the coase theorem is necessary but not sufficient for two sidedness the paper builds a model integrating usage and membership externalities that unifies two hitherto disparate strands of the literature emphasizing either form of externality and obtains new results on the mix of membership and usage charges when price setting or bargaining determine payments between end users

competition and incentives with motivated agents a unifying theme in the literature on organizations such as public bureaucracies and private nonprofits is the importance of mission as opposed to profit as an organizational goal such mission oriented organizations are frequently staffed by motivated agents who subscribe to the mission this paper studies incentives in such contexts and emphasizes the role of matching the mission preferences of principals and agents in increasing organizational efficiency matching economizes on the need for high powered incentives it can also however entrench bureaucratic conservatism and resistance to innovations the framework developed in this paper is applied to school competition incentives in the public sector and in private nonprofits and the interdependence of incentives and productivity between the private for profit sector and the mission oriented sector through occupational choice jel d23 d73 h41 l31 the late twentieth century witnessed a historic high in the march of market capitalism with unbridled optimism in the role of the profit motive in promoting welfare in the production of private goods moreover this generated a broad consensus on the optimal organization of private good production through privately owned competitive firms when it comes to the provision of collective goods no such consensus has emerged debates about the relative merits of public and private provision still dominate this paper suggests a contracting approach to the provision of collective goods it focuses on two key issues how to structure incentives and the role of competition between providers at its heart is the idea that organizations that provide collective goods cohere around a mission 2 thus production of collective goods can be viewed as mission oriented

dutch disease and the mitigation effect of migration evidence from canadian provinces this article evaluates whether immigration can mitigate the dutch disease effects associated with booms in natural resource sectors we derive predicted changes in the size of the non tradable sector from a small general equilibrium model a la obstfeld rogoff using data for canadian provinces we find evidence that aggregate immigration mitigates the increase in the size of the non tradable sector in booming regions the mitigation effect is due mostly to interprovincial migration and temporary foreign workers there is no evidence of such an effect for permanent international immigration interprovincial migration also results in a spreading effect of dutch disease from booming to non booming provinces

the use and usefulness of performance measures in the public sector the paper focuses on the empirical evidence on the use and usefulness of performance measures in the public sector it begins with consideration of the features of the public sector which make the use of performance measures complex the issues of multiple principals and multiple tasks it discusses the form that performance measures may take the use made of these measures and the responses that individuals may make to them empirical examples from the fields of education and health with a focus on the usa and uk are examined there is clear evidence of responses to such measures some of these responses improve efficiency but others do not and fall into the category of gaming generally there has been little assessment of whether performance measures bring about improvements in service the paper ends with consideration of how such measures should be used and what measures are useful to collect

a simple framework for analysing various real aspects of stabilisation and structural adjustment policies this article shows how a simple geometric framework containing a real model based on the standard two good three factor trade theoretic model and a monetary model of the domestic banking system can be used to analyse the changes in the real and nominal values of various economic variables of concern resulting from stabilisation and structural adjustment policies

international redistribution of income summary how do international policies on aid trade and factor movements affect the international distribution of income we calculate the impact by world decile of the actual level of aid flows and the effect on income of merchandise trade restrictions by high income countries we find that aid s distributional impact is equality enhancing extremely small in terms of changes in inequality measures but of some importance for the lowest decile of the distribution we also find that some of this impact is counteracted by lost potential income in the lower deciles from merchandise trade barriers imposed by high income countries

resource boom wages and unemployment theory and evidence from the norwegian petroleum experience the effects of norwegian petroleum activities on nominal wages and the rate of unemployment are analyzed in this paper the theoretical model is based on standard theory of segmented labor markets increased nominal wages in the petroleum sector will unambiguously increase the wage level and the rate of unemployment increased petroleum employment will under realistic assumptions also raise the wage level the effect on the rate of unemployment in this case is ambiguous the empirical model is embedded in reduced forms of the theoretical model and the estimated parameters are consistent with the theoretical results

macro policy responses to natural resource windfalls and the crash in commodity prices policy prescriptions for managing natural resource windfalls are based on the permanent income hypothesis none of the windfall is invested at home and saving in an intergenerational swf is dictated by smoothing consumption across different generations furthermore with dutch disease effects the optimal response is to intertemporally smooth the real exchange rate smooth public and private consumption and limit sharp fluctuations in the intersectoral allocation of production factors we show that these prescriptions need to be modified for the following reasons first to cope with volatile commodity prices precautionary buffers should be put in a stabilisation fund second with imperfect access to capital markets the windfall must be used to curb capital scarcity invest domestically and bring consumption forward third with real wage rigidity consumption must also be brought forward to mitigate transient unemployment fourth the real exchange rate has to temporarily appreciate to signal the need to invest in the domestic economy to gradually improve the ability to absorb the extra spending from the windfall fifth with finite lives the timing of handing back the windfall to the private sector matters and consumption and the real exchange rate will be volatile finally with nominal wage rigidity we show that a taylor rule is a better short run response to a crash in commodity prices than a nominal exchange rate peg

natural disasters and labor markets abstract while it is clear that natural disasters have serious welfare consequences for affected populations less is known about how local labor markets in low income countries adjust to such large shocks combining data from the indonesia family life survey the desinventar database the u s geological survey and district level employment indicators this paper explores how a large earthquake in indonesia affected labor market outcomes in particular the evolution of wages across sectors i find that the earthquake had a positive effect on wage growth for workers who were employed in the agricultural sector at baseline i propose two mechanisms for this result a higher growth rate of the price of rice and a downward shift in the supply of workers in the agricultural sector i show that evidence mainly supports the latter labor shifted out of the agricultural sector into the construction sector raising the marginal product of labor in agriculture

comparative advertising disclosing horizontal match information improved consumer information about horizontal aspects of products of similar quality leads to better consumer matching but also to higher prices so consumer surplus can go up or down while profits rise with enough quality asymmetry though the higher quality and hence larger firm s price falls with more information so both effects benefit consumers this occurs when comparative advertising is used against a large firm by a small one comparative advertising as it imparts more information therefore helps consumers although it also improves the profitability of the small firm overall welfare goes down because of the large loss to the attacked firm

the political economy of economic liberalization two of the major policy problems facing governments of developing countries in the 1 980s have been unsustainable external and internal disequilibria and implementation of politically feasible stabilization cum liberalization programs which become necessary to correct these imbalances this article discusses these crises and subsequent policy reform the analysis suggests that balance of payments and fiscal deficits are frequently the result of use of an incorrect accounting system in a fixed exchange rate economy and of public sector expansion beyond its economically feasible size that governments usually seek to liberalize their economies during a crisis to regain control when the growth of the transfer state has led to generalized tax resistance avoidance or evasion that reduction of the government role will be required to alleviate these crises that sharp departures from past policies rather than gradual reform may be politically necessary and that contrary to the current technocratic opinion on this matter the sequencing of a consistent and credible package of reforms which will most effectively reduce the costs of adjustment is initial liberalization of domestic capital markets simultaneous with cuts in the fiscal deficit followed by floating the exchange rate and then commodity market liberalization with the growing importance of internal monetary fund imf stabilization and world bank structural adjustment programs there has been concern about the proper sequencing of the standard stabilization cum liberalization measures contained in these packages in particular there is grave concern at the very mixed and in some cases disastrous effects of liberalization attempts on incomes and employment in the southern cone of latin america in the late 1970s and early 1 980s much of the existing discussion of the order of liberalization is conducted within the traditional technocratic framework which seeks to determine the welfare cost minimizing deployment of policies in the standard stabilization and 1 this assumes a benevolent and well informed government maximizing a social welfare function

oil windfalls and export diversification in oil producing countries evidence from oil booms abstract this paper examines the factors behind export diversification in oil countries specifically we investigate the impact of oil booms on export diversification through an empirical framework the paper finds that economy s export structure before the oil boom determines whether oil windfalls might affect the diversification process thus an oil boom negatively affects export diversification only if countries initially exhibit low levels of diversification in countries with a high level of diversification before the boom an oil boom has no impact on diversification these results are based on a large sample of 134 countries and are robust to various sensitivity analyses they are corroborated with data from the manufacturing sector which show that oil booms only reduce diversification in countries with a small manufacturing sector prior to the boom

natural resources democracy and corruption we study how natural resources can feed corruption and how this effect depends on the quality of the democratic institutions our game theoretic model predicts that resource rents lead to an increase in corruption if the quality of the democratic institutions is relatively poor but not otherwise we use panel data covering the period 1980 to 2004 and 124 countries to test this theoretical prediction our estimates confirm that the relationship between resource rents and corruption depends on the quality of the democratic institutions our main results hold when we control for the effects of income time varying common shocks regional fixed effects and various additional covariates they are also robust across different samples and to the use of various alternative measures of natural resources democracy and corruption

macroeconomic policy in an oil exporting economy with foreign exchange controls the sudden and sharp increases in oil prices during the past decade and the discovery and extraction of oil in the north sea have recently contributed to a renewal of interest in the macroeconomic problems of oil exporting countries in general and those of industrialized and semi industrialized oilexporting countries such as the uk and mexico in particular the economic implications of the north sea oil revenues for the british economy have been hotly debated by forsyth and kay 1980 1981 worswick 1980 barker 1981 corden 1981 and byatt et al 1982 the effects of oil and gas revenues on the economies of canada mexico the netherlands norway and the uk have also been the subject of analysis and discussion in barker and brailovsky 1981 despite their important contribution these studies fall short of formulating a comprehensive theoretical framework for the study of macroeconomic policy in oil exporting countries in general the resurgence of interest in the macroeconomics of oil exporting economies and the lack of a satisfactory theoretical framework emphasize the need for the explicit introduction of an oil sector into macroeconomic models of the open economy the more recent studies by buiter and purvis 1983 eastwood and venables 1982 corden and neary 1982 and neary and purvis 1982 have gone some way towards meeting this need but they are better suited to the study of macroeconomic policy in developed oil exporting countries such as the united kingdom where highly developed financial markets already exist 1 without exception all these studies assume that the economy under consideration operates with a floating exchange rate and that the private capital is internationally mobile they also invariably ignore the short term and the long term financial repercussions of changes in oil income that operate via the government budget constraint and the asset position of the private sector these assumptions are however inappropriate for most oil exporting countries in the middle east africa and latin america the purpose of this paper is to examine the short run and long run macroeconomic consequences of an increase in oil revenues in an oil exporting country characterized by strict foreign exchange controls on private capital flows we attempt to do this in the context of a keynesian underemployment model of the type analysed for example by turnovsky and kaspura 1974 branson 1976 and argy and salop 1979 but with domestic prices set according to a mark up rule along the lines advocated for example by fetherston and godley 1978 1981 unlike argy and salop but in line with other recent contributions to the macroeconomic theory of open economies the present paper explicitly allows for the existence of the government budget constraint and analyses the macroeconomic effects of changes in oil revenues both in the short run when
