where do markets come from production markets have two sides producers are a fully connected clique transacting with buyers as a separate but aggregated clique each producer is a distinctive firm with a distinctive product each side continually monitors reactions of the other through the medium of a joint social construction the schedule of terms of trade each producer is guided in choice of volume by the tangible outcomes of other producers not by speculation on hypothetical reactions of buyers to its actions each producer acts purely on self interest based on observed actions of all others summarized through a feedback process the summary is the terms of trade schedule which reduces to constant price only in limiting cases the market emerges as a structure of roles with a differentiated niche for each firm explicit formulae both for firms and for market aggregates are obtained by comparative statics methods for one family of assumptions about cost structures and about buyers evaluations of differentiated products not just any set of firms can sustain terms of trade with any set of buyers there prove to be three main kinds of markets and three sorts of market failure within a parameter space that is specified in detail one sort of market paradox has a madison avenue flavor another is more conventional grind and a third crowded is a new form not included in any existing theory of markets current american industrial markets are drawn on for 20 illustrations of which three are presented in some detail inequality in firms market shares measured by gini coefficients is discussed

the contingent effect of social capital on performance of professional athletes life cycle stages and changes in regulation as moderators motorboat racing is a sport organized as public gambling in japan as well as physical strength and driving technique skills to adjust equipment are critical for racers to win a race based on the contingency theory of social capital this study analysed comprehensive panel data of motorboat racers and revealed that bonding and bridging social capital had different impacts on performance according to life cycle stages of racers and changes in regulation first bonding social capital has a positive impact on performance when racers are less experienced and most need psychological aid stemming from strong ties second bridging social capital has a positive impact on performance when racers are more experienced and have accumulated absorptive capacity to learn efficiently from diverse sources of knowledge third both bonding and bridging social capital lose their explanatory power after the changes in regulation that shifted ownership of propellers from racers to the authority which could mitiga

competition and social influence the diffusion of the sixth generation processor in the global computer industry1 when is a social actor most strongly influenced by its peers this article addresses this question by clarifying when computer firms were most strongly affected by the choices of their structurally equivalent rivals to adopt a well known technology intel s sixth generation processor the core hypothesis is that the effect of adoptions by structurally equivalent firms increases with the competitive pressure that a focal firm faces in its market position the results show that a chosen firm is most strongly influenced by comparable others when it faces scale based competition and is diversified the implications of this study are twofold a social actor s sensitivity to the conduct of others may depend not only on its place in a hierarchy but also on the nature of its ties to an external audience and a contingent theory of social influence may be necessary to characterize diffusion processes correctly particularly when external and time varying nonnetwork factors have significant effects

from the classical economists to empiricists a review of the terms of trade controversy contrary to the classical position the works of prebisch and singer in the middle of the last century launched the controversial hypothesis of a long term decline in the terms of trade of primary products vis a vis manufactured goods and a corresponding decline in the terms of trade of developing countries vis a vis advanced ones the present study traces the origin and evolution of the hypothesis and reviews the related statistical debate it also reviews the theoretical support for the prebisch singer hypothesis it is an exercise in the history of economic thought to trace how the controversies surrounding the terms of trade have evolved over time specifically noting that with the development of the field of econometrics the central thesis of the argument got lost somewhere in the realm of hi tech statistical debates

the social structure of a national securities market in this article a national securities market the stock options market is characterized as a social structure represented by the networks of actors who traded options on the floor of a major securities exchange trading among actors exhibited distinct social structural patterns that dramatically affected the direction and magnitude of option price volatility the argument that this market is socially structured is constructed in four parts behavioral assumptions about the nature of economic actors models of micronetworks models of macronetworks and price consequences in the ideal typical model of the market actors are assumed to be hyperrational and never to act opportunistically with these behavioral assumptions the micronetworks of actors should be expansive a condition which would result in undifferentiated and homogeneous macronetworks such macronetworks would tend to reduce the volatility of option prices but in the empirical market studied here actors are subject to bounded rationality a

unit roots flexible trends and the prebisch singer hypothesis abstract this paper studies the dynamic properties of relative commodity prices especially the prebisch singer hypothesis on their secular decline using a new family of unit root tests based on the fourier approximation to the data s underlying trend the approximation controls for low frequency variations such as structural breaks or the long swings induced by hypothesized super cycles in the data regarding the extant literature we find considerably more evidence against nonstationarity in relative commodity prices and very limited support for the prebisch singer hypothesis

the impact of terms of trade and real exchange rate volatility on investment and growth in sub saharan africa abstract specialization in primary product exports reduces growth but why adverse trends in and the high variance of primary product prices are possible explanations the impact on investment and growth of the level and volatility of the terms of trade and the real effective exchange rate is estimated for a panel of 14 sub saharan african countries over 1980 1995 growth is negatively affected by terms of trade instability and investment by real exchange rate instability both growth and investment increase when the terms of trade improve and real exchange rate overvaluation is eliminated

long run trends in 26 primary commodity prices abstract this paper uses time series techniques to re examine the prebisch singer hypothesis that there has been a secular deterioration in primary commodity prices in terms of manufactured goods instead of using price indices it considers 26 individual commodity prices over the period 1900 1983 this avoids possible aggregation and interpretation problems associated with the use of aggregate indices the study finds that 16 of the 26 prices are trendless five have statistically significant negative trends the remaining five have positive trends it concludes that the prebisch singer hypothesis should certainly not be considered a universal phenomenon or stylized fact

are external shocks responsible for the instability of output in low income countries external shocks such as commodity price fluctuations natural disasters and the role of the international economy are often blamed for the poor economic performance of low income countries the author quantifies the impact of these different external shocks using a panel vector autoregression var approach and compares their relative contributions to output volatility in low income countries vis a vis internal factors he finds that external shocks can only explain a small fraction of the output variance of a typical low income country internal factors are the main source of fluctuations from a quantitative perspective the output effect of external shocks is typically small in absolute terms but significant relative to the historic performance of these countries

the stability of american markets much of the evidence of coordination between corporations and their markets comes from cross sectional conducted within portions of the american economy during the past two decades we know especially for manufacturing during the late 1960s that certain structural qualities of markets predict profits and the organization of large firms but this evidence is open to an uncomfortable empirical question to what extent did the social structural qualities determining resource dependence in american markets change during the 1960s and 1970s so as to limit the generalizability of cross sectional evidence the analysis here shows that markets were dramatically stable in he social structure of production relations known to predict the structure of large firms relying principally on department of commerce data the article traces the american economy through the 1960s and 1970s in terms of 77 broadly defined markets describing the stability of market boundaries and patterns of transactions with suppliers and c

the empirical merit of structural explanations of commodity price volatility review and perspectives this paper presents both the history of and state of the art in empirical modeling approaches to the world commodity price volatility the analysis builds on the storage model and key milestones in its development specifically it is intended to offer a reader unfamiliar with the relevant literature an insight into the modeling issues at stake from both a historical and speculative viewpoint the review considers primarily the empirical techniques designed to assess the merits of the storage theory it does not address purely statistical approaches that do not rely on storage theory and that have been studied in depth in other streams of the commodity price literature the paper concludes with some suggestions for future research to try to resolve some of the existing empirical flaws and hopefully to increase the explanatory power of the storage model

natural disasters in a two sector model of endogenous growth using an endogenous growth model with physical and human capital accumulation this paper considers the sustainability of economic growth when the use of a polluting input e g fossil fuels intensifies the risk of capital destruction through natural disasters we find that growth is sustainable only if the tax rate on the polluting input increases over time the long term rate of economic growth follows an inverted v shaped curve relative to the growth rate of the environmental tax and it is maximized by the least aggressive tax policy of those that asymptotically eliminate the use of polluting inputs unavailability of insurance can accelerate or decelerate the growth maximizing speed of the tax increase depending on the relative significance of the risk premium and precautionary savings effects welfare is maximized under a milder environmental tax policy especially when the pollutants accumulate gradually

cross country heterogeneity in intertemporal substitution abstract we collect 2735 estimates of the elasticity of intertemporal substitution in consumption from 169 published studies that cover 104 countries during different time periods the estimates vary substantially from country to country even after controlling for 30 aspects of study design our results suggest that income and asset market participation are the most effective factors in explaining the heterogeneity households in rich countries and countries with high stock market participation substitute a larger fraction of consumption intertemporally in response to changes in expected asset returns micro level studies that focus on sub samples of rich households or asset holders also find systematically larger values of the elasticity

consumption pollution tradeoffs in an environment vulnerable to pollution related catastrophic collapse abstract this paper considers the consequences of an avoidable risk of irreversible environmental catastrophe for society s optimal long run consumption pollution tradeoffs the risk is assumed to be a nondecreasing function of pollution concentration which evolves as a dynamic environmental renewal process the main objective of the paper is to derive qualitative insights regarding the effects of such risk on optimal management

agriculture s terms of trade issues and implications the article addresses 1 the issue of what agricultural commodity prices should be compared to if we are concerned with the welfare of agriculturalists 2 the general absence of product quality adjustment when analysis is undertaken comparing agricultural to manufactured goods prices 3 the extent to which energy prices are or will be the driver of both manufactured and agricultural prices and 4 the importance of considering agriculture s terms of trade tot against the service sector since the service sector is typically the largest in the economy it reflects on the basic question of whether the widespread perception that agriculture s tot secularly decline is correct

the economics of organization the transaction cost approach the transaction cost approach to the study of economic organization regards the transaction as the basic unit of analysis and holds that an understanding of transaction cost economizing is central to the study of organizations applications of this approach require that transactions be dimensionalized and that alternative governance structures be described economizing is accomplished by assigning transactions to governance structures in a discriminating way the approach applies both to the determination of efficient boundaries as between firms and markets and to the organization of internal transactions including the design of employment relations the approach is compared and contrasted with selected parts of the organization theory literature

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

human capital risk and economic growth this paper develops a tractable incomplete markets model of economic growth in which households invest in risk free physical capital and risky human capital the paper shows that a reduction in uninsurable idiosyncratic labor income risk decreases physical capital investment but increases human capital investment growth and welfare a quantitative analysis based on a calibrated version of the model reveals that these effects are substantial and of the same order of magnitude as the effects of distortionary income taxation the analysis further suggests that government sponsored severance payments to displaced workers increase growth and welfare even if these payments have to be e nanced through distortionary income taxation

commodity price excess co movement from a historical perspective 1900 2010 abstract pindyck and rotemberg 1990 s excess co movement hypothesis states that commodity prices move together beyond what fundamentals can explain reflecting possibly traders herding or liquidity constraints we test for price excess co movement in 12 commodities 11 non energy ones and oil spanning over a hundred years 1900 2010 to this end we approximate commodity demand supply factors by their apparent consumption we carry out several tests and find some evidence in favor of excess co movement but its nature appears to be time dependent in particular we conclude that excess co movement with oil is generally present particularly in the industrial metal class we also explore the interdependence between portfolio investment decisions and excess co movement for three unrelated assets cotton copper and petroleum based on conditional value at risk cvar optimization we found some correlations between the two when short sales are excluded during 1971 1999 2004 and 2008

a theory of disasters and long run growth abstract this paper develops a unified framework in which various types of catastrophic shocks can be simultaneously considered within a standard model of economic growth we first establish the basic existence and equivalence results we then apply the framework to an endogenous growth model to consider the influence of disasters on the long term equilibrium and the transition phase the result shows that while experiencing disasters may lower the average growth rate of the affected countries there exist various channels through which the risk of disasters and long term economic performance are positively correlated this finding reconciles the apparently contradictory evidence in recent empirical studies

the macroeconomic consequences of disasters abstract natural disasters have a statistically observable adverse impact on the macro economy in the short run and costlier events lead to more pronounced slowdowns in production yet interestingly developing countries and smaller economies face much larger output declines following a disaster of similar relative magnitude than do developed countries or bigger economies a close study of the determinants of these adverse macroeconomic output costs reveals several interesting patterns countries with a higher literacy rate better institutions higher per capita income higher degree of openness to trade and higher levels of government spending are better able to withstand the initial disaster shock and prevent further spillovers into the macro economy these all suggest an increased ability to mobilize resources for reconstruction financial conditions also seem to be of importance countries with more foreign exchange reserves and higher levels of domestic credit but with less open capital accounts appear more robust and better able to endure natural disasters with less adverse spillover into domestic production

rare disasters asset prices and welfare costs a representative consumer model with epstein zin weil preferences and i i d shocks including rare disasters accords with observed equity premia and risk free rates if the coefficient of relative risk aversion equals 3 4 if the intertemporal elasticity of substitution exceeds one an increase in uncertainty lowers the price dividend ratio for equity and a rise in the expected growth rate raises this ratio calibrations indicate that society would willingly reduce gdp by around 20 percent each year to eliminate rare disasters the welfare cost from usual economic fluctuations is much smaller though still important corresponding to lowering gdp by about 1 5 percent each year

international risk sharing and economic growth international risk sharing which diversifies away income risk will reduce saving with constant relative risk aversion if growth arises from the external effects of human capital accumulation then reducing saving will reduce growth welfare also may fall with risk sharing because endogenous growth with external effects of capital accumulation typically implies a competitive equilibrium growth rate already less than the optimal growth rate we demonstrate these results in a standard representative agent economy diversifying away rate of return risk also will reduce saving and growth rates if relative risk aversion exceeds one but this diversification always increases welfare this paper studies the effects of international risk sharing portfolio diversification in a world economy in which growth rates of income are endogenous growth is based upon the spillover effects of human capital accumulation as in lucas 1988 and romer 1986 there are positive economy wide spillovers of human capital intensity on individual labour productivity in section 2 we construct a multi country growth model with an infinitely lived representative agent in each country each country faces income risk but there is no aggregate uncertainty at the world level we focus on two market structures in the first structure there are no markets which allow for international diversification of country specific income risk in the second structure there are complete international markets for risksharing with no aggregate world uncertainty this completeness allows full diversification of country specific risk the paper has two central results first growth rates in all countries are lower in the equilibrium with full diversification second in this same structure welfare of each country may be lower than in an equilibrium without risk sharing the reasoning is as follows with external effects of capital accumulation the compet

biological conservation in dynamic agricultural landscapes effectiveness of public policies and trade offs with agricultural production article i nfo land use change and land management intensification are major drivers of biodiversity loss especially in agricultural landscapes that cover a large and increasing share of the world s surface incentive based agri environmental policies are designed to influence farmers land use decisions in order to mitigate environmental degradation this paper evaluates the effectiveness of agri environmental schemes for biological conservation in a dynamic agricultural landscape under economic uncertainty we develop a dynamic ecological economic model of agricultural land use and spatially explicit population dynamics we then relate policies subsidies to grassland taxation of agricultural intensity to the ecological outcome probability of persistence of a species of interest we also analyze the associated trade offs between agricultural production in value and biological conservation in probability of persistence at the landscape scale

dynamic persistence of primary commodity prices this article examines the persistence of shocks to international commodity prices from 1900 to 2008 using the updated grilli yang index the main innovation of this study is that it determines whether commodity prices are characterized by multiple changes in persistence specifically bootstrap methods are used to estimate persistence and the associated half life shocks are calculated we find that the persistence of shocks can vary widely depending on the individual commodity and the time period the results suggest that policy makers need to exercise caution when introducing measures to cushion the effect of shocks to world commodity prices

pollution control in an uncertain environment abstract the effects of the threat of occurrence of environmental catastrophes on optimal pollution control are considered recent analysis of irreversible events is extended to two types of reversible events single occurrence and multiple occurrence recurrent events while it is possible that the threat of irreversible events induces more pollution we show that reversible events under quite general conditions induce more conservation less pollution the analysis is carried out via a simple method the h method to identify optimal steady states by comparing steady state policies with small variations from them for recurrent events the optimal state process must approach a unique steady state from any initial level in this case the h method characterizes the dynamic behavior of the optimal state process without actually solving for it

primary commodity prices manufactured goods prices and the terms of trade of developing countries what the long run shows the authors revisit in this article the empirical foundation of the alleged secular decline in the prices of primary commodities relative to those of manufactures they use a newly constructed index of commodity prices and two modified indexes of manufactured good prices and find that from 1900 to 1986 the relative prices of all primary commodities fell on trend by 0 5 percent a year and those of nonfuel primary commodities by 0 6 percent a year they thus confirm the sign but not the magnitude of the trend implicit in the work of prebisch but even the more limited secular decline shown by their relative price indexes may be magnified by an incomplete account of quality improvements in manufactures they then show that the evolution of terms of trade of nonfuel primary commodities is not the same as that of the net barter terms of trade of non oil exporting developing countries finally they find that despite the decline that has probably occurred during the current century in the terms of trade of nonfuel primary commodities the purchasing power of total exports of these products has increased considerably similarly the fall that may have occurred after world war ii in the net barter terms of trade of developing countries seems to have been more than compensated for by the steady improvement in their income terms of trade

economic development and the impacts of natural disasters abstract we use disaster impact data over time to examine the degree to which the human and economic losses from natural disasters are reduced as economies develop we find that countries with higher income higher educational attainment greater openness more complete financial systems and smaller government experience fewer losses

on endogenous growth with physical and human capital this paper presents a class of models in which agents may devote part of their nonleisure activities to going to school so as to increase the efficiency units of labor they supply to the firms and the wages they receive the interaction among the technology of human capital accumulation and agents preferences will determine endogenously the economy s rate of growth given a constant returns to scale technology for physical capital accumulation we characterize the set of steady states as a ray from the origin and show the global convergence of every off balanced path to some point on this ray further properties concerning the dynamic evolution of the state and control variables around the ray of steady states are also established our analysis is useful to understand the role played by the technologies of physical and human capital in the process of accumulation and to evaluate the impact of policies geared toward attaining higher levels of capital our results highlight the importance of human capital

the macroeconomic consequences of terrorism abstract we perform an empirical investigation of the macroeconomic consequences of international terrorism and interactions with alternative forms of collective violence our analysis is based on a rich unbalanced panel data set with annual observations on 177 countries from 1968 to 2000 which brings together information from the penn world table data set the iterate data set for terrorist events and data sets of external and internal conflict we explore these data with cross sectional and panel growth regression analysis and a structural var model we find that on average the incidence of terrorism may have an economically significant negative effect on growth albeit one that is considerably smaller and less persistent than that associated with either external wars or internal conflict as well terrorism is associated with a redirection of economic activity away from investment spending and towards government spending however our investigation also suggests important differences both regarding the incidence and the economic consequences of terrorism among different sets of countries in oecd economies in particular terrorist incidents are considerably more frequent than in other nations but the negative influence of these incidents on growth is smaller

when grilli and yang meet prebisch and singer piecewise linear trends in primary commodity prices abstract in this study we test the prebisch singer hypothesis on the secular decline of relative primary commodity prices with the extended grilli and yang 1988 data set ending at 2010 rather than asking whether it holds for the whole sample period we examine if the hypothesis holds sometimes during the sample period by estimating the piecewise linear trends of primary commodity prices we employ the new l1 trend filtering proposed by kim et al 2009 to estimate the piecewise linear trends we find that the prebisch singer hypothesis holds sometimes but not always for many of the primary commodities in the grilli yang data the strength of the prebisch singer hypothesis has become substantially weaker recently as the relative prices of many primary commodities have increased sharply since around 2000

commodity booms and busts in emerging economies abstract emerging economies particularly those dependent on commodity exports are prone to highly disruptive economic cycles this paper proposes a small open economy model for a net commodity exporter to quantitatively study the triggers of these cycles the economy consists of two sectors one of which produces commodities with prices subject to exogenous international fluctuations these fluctuations affect both the competitiveness of the economy and its borrowing terms as higher commodity prices are associated with lower spreads between the country s borrowing rate and world interest rates both effects jointly result in strongly positive effects of commodity price increases on gdp consumption and investment and a negative effect on the total trade balance furthermore they generate excess volatility of consumption over output and a large volatility of investment besides explicitly incorporating a double role of commodity prices the model structure nests the various candidate sources of shocks proposed in previous work on emerging economy business cycles estimating the model on argentine data we find that the contribution of commodity price shocks to fluctuations in post 1950 output growth is in the order of 38 in addition commodity prices account for around 42 and 61 of the variation in consumption and investment growth respectively we find transitory productivity shocks to be an important driver of output fluctuations exceeding the contribution of shocks to the trend which though smaller is not negligible

a short note on updating the grilli and yang commodity price index the grilli and yang commodity price index is one of the most widely used commodity price series in the applied economics literature this note provides some practical advice on updating this data series by listing the base period index values identifying relevant data sources and describing a method for computing subindex weights in 1988 enzo grilli and maw cheng yang published their seminal article on the long run development of an index of 24 primary commodity prices gycpi deflated by an index of manufactured goods unit values the sample of average annual primary commodity prices covers about 54 percent of the primary commodity trade in the index reference period 1977 79 the deflators considered for manufacturing prices were the u s manufacturing price index usmpi and the manufacturing unit value index muv 1widely used and discussed the grilli and yang data set has been extended by a number of researchers the data have been employed in a variety of contexts in later studies thus the gycpi data continue to enjoy wide popularity in their own right and as a benchmark for new approaches to empirical studies
