similarities and convergence in g 7 cycles this paper examines the properties of g 7 cycles using a multicountry bayesian panel var model with time variations unit specific dynamics and cross country interdependences we demonstrate the presence of a significant world cycle and show that country specific indicators play a much smaller role we detect di erences across business cycle phases but apart from an increase in synchronicity in the late 1990s find little evidence of major structural changes we also find no evidence of the existence of an euro area specific cycle or of its emergence in the 1990s

will business cycles in the euro area converge a critical survey of empirical research this survey of business cycle synchronization in the european monetary union focuses on two issues have business cycles become more similar and which factors drive business cycle synchronization we conclude that business cycles in the euro area have gone through periods of both convergence and divergence still there is quite some evidence that during the 1990s business cycle synchronization in the euro area has increased higher trade intensity is found to lead to more synchronization but the point estimates vary widely the evidence for other factors affecting business cycle synchronization is very mixed

debt dynamics in europe a network general equilibrium gvar approach in this work we investigate the dynamic interdependencies among the eu12 economies using a competitive general equilibrium network system representation additionally using bayesian techniques we estimate the autoregressive scheme that characterizes the equilibrium price system of the network while characterizing each economy node in the universe of our network in terms of its degree of pervasiveness in this context we unveil the dominant s unit s in our model and estimate the dynamic linkages between the economies nodes lastly in terms of robustness analysis we compare the findings of the degree pervasiveness of each economy against other popular quantitative methods in the literature according to our findings the economy of germany acts as weakly dominant entity in the eu12 economy meanwhile all shocks die out in the short run without any long lasting effect

induced innovation in american agiculture a reconsideration this paper investigates the role of induced innovation in the development of american agriculture from 1880 to 1980 the induced innovation hypothesis most closely associated with the work of hayami and ruttan argues that successful economies develop technologies in accordance with market price signals to loosen constraints on growth imposed by factor scarcities our analysis employing new state and regional level data fails to find support for hayami and ruttan s hypothesis this paper suggests that many of the fundamental generalizations about american agricultural development need to be reconsidered and redirects attention to the role of settlement changing crop patterns and biological investments in explaining changes in factor utilization in american agriculture

negotiating an agreement on global warming a theoretical analysis abstract the outcome of international negotiation on combatting global warming is derived and analyzed using a two country bargaining model it is shown that while side payments between countries will generally be part of an agreement some of these payments are made purely as a result of asymmetry in bargaining power and have nothing to do with the polluter pays principle or the victim pays principle factors affecting the outcome of negotiation include a country s size of population the welfare level at the disagreement point and the order of making offers the enforcement issue is also discussed

co operation and unilateral commitment in the presence of global environmental problems this paper focuses on the link between group co operation and unilateral commitment of some countries in the presence of global environmental problems we show that in case of a failure of negotiation some countries can decide to commit unilaterally and reduce their emissions we call this behaviour precautionary commitment absence of international agreement does not mean global defection from the environmental issue we also show that the emergence of a non co ordinated global co operation can result from a strategic action from the members of the coalition the insiders of the coalition create an incentive for the non members to reduce without co ordinating their emissions

tests of a rational theory of the size of government in many countries the political party holding power changes more frequently than the trend growth rates in government spending and taxes shifts of political power are often preceded by rhetoric about meeting needs or cutting taxes which post election performances rarely match yet changes in the size of government up and down occur on average the size of government measured by the share of taxes or spending to output has increased in many countries during the past century but changes in size occur at diffrent rates and at times the relative size of government declines

government growth in the twenty first century public choice explanations of government growth fall into three main categories budget maximization theories rational choice models and path dependent models like the ratchet hypothesis the strengths and weaknesses of these theories as explanations for government growth are considered along with some facts about the actual growth of government to conjecture about its trajectory in the twenty first century government size seems to have been constrained in the past primarily by its ability to raise revenue growth rates in the new century thus appear to depend on factors constraining government s ability to continue to expand the tax base

tax base variability and procyclical fiscal policy in developing countries abstract based on a sample of 56 countries we show that fiscal policy in the g7 countries appears to be acyclical while fiscal policy in developing countries is procyclical i e fiscal policy is expansionary in good times and contractionary in bad times to explain this puzzle we develop an optimal fiscal policy model in which running budget surpluses is costly because they create pressures to increase public spending given this distortion a government that faces large fluctuations in the tax base as is the case for developing countries will find it optimal to run a procyclical fiscal policy

determinants and consequences of land reform implementation in the philippines abstract unlike the experience of other developing countries land reform in the philippines has been successful in converting many of share tenants to land reform beneficiaries this study indicates that the implementation of land reform is positively associated with yield growth made possible by the adoption of modern seed fertilizer technology a major reason underlying such association is considered to be an increased economic interest of tenants in land reform arising from divergence of rental value of land from leasehold rent and amortization fees prescribed by law

the problem of global environmental protection what distinguishes global common property problems and global unidirectional externalities from the ones that arise under a single jurisdiction is that there is no global authority empowered to intervene and regulate use of global environmental resources cooperation is needed the paper discusses when cooperation is most needed and how it might be obtained cooperation might emerge from a noncooperative setting if supergames are played if the actions of any one country are explicitly contingent on the actions undertaken by other countries or if moral concerns lead countries to consider the consequences of their actions for others cooperation emerges in an explicit though limited form when countries commit to regulate themselves in signing international agreements in these cases the signatories cooperate but the agreements are self enforcing an attempt is made to relate these theoretical concepts to the practice of global environmental protection copyright 1990 by oxford university press

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

ldc agriculture nonparametric malmquist productivity indexes abstract this paper examines changes in agricultural productivity in 18 developing countries over the period 1961 1985 we use the nonparametric output based malmquist index to examine whether the results from such an approach confirm results from other methods that have indicated declining agricultural productivity in less developed countries ldcs the results confirm previous findings indicating that at least half of these countries have experienced productivity declines in agriculture we also found that those countries that tax agriculture most heavily had the most negative rates of productivity change

green revolution and labour demand in rice farming the case of central luzon 1966 90 while the adoption of modern rice varieties mvs increased labour requirements for crop care and other activities it might have induced the adoption of labour saving technologies thus whether the net impact of mv adoption on labour demand is significantly positive is still debated in the green revolution literature using farm level survey data collected in central luzon from 1966 to 1990 this study estimated simultaneously the labour saving technology adoption and the labour demand functions we found among other things that mvs increased labour demand significantly without inducing the widespread adoption of labour saving technologies

a real model of the world business cycle abstract in this paper a stochastic two country log linear infinite horizon model is used to analyze the generation and transmission of economic fluctuations across countries it is argued that following a country specific supply disturbance production interdependence and unitary elasticities in consumption and production are sufficient to generate comovements in aggregate economic activity investment and trade that are persistent over time and positively correlated across countries however the empirical analysis carried out for the usa japan germany and uk for the 1960 82 period suggests that common shocks rather than trade links are responsible for this pattern of comovements

the use of bootstrapped malmquist indices to reassess productivity change findings an application to a sample of polish farms this article assesses the extent to which sampling variation affects findings about malmquist productivity change derived using data envelopment analysis dea in the first stage by calculating productivity indices and in the second stage by investigating the farm specific change in productivity confidence intervals for malmquist indices are constructed using simar and wilson s 1999 bootstrapping procedure the main contribution of this article is to account in the second stage for the information in the second stage provided by the first stage bootstrap the dea ses of the malmquist indices given by bootstrapping are employed in an innovative heteroscedastic panel regression using a maximum likelihood procedure the application is to a sample of 250 polish farms over the period 1996 to 2000 the confidence intervals results suggest that the second half of 1990s for polish farms was characterized not so much by productivity regress but rather by stagnation as for the determinants of farm productivi

the impact of global warming on agriculture a ricardian analysis reply we measure the economic impact of climate on land prices using cross sectional data on climate farmland prices and other economic and geophysical data for almost 3 000 counties in the united states we find that higher temperatures in all seasons except autumn reduce average farm values while more precipitation outside of autumn increases farm values applying the model to a global warming scenario shows a significantly lower estimated impact of global warming on u s agriculture than the traditional production function approach and in one case suggests that even without co sub 2 fertilization global warming may have economic benefits for agriculture 16 refs 5 figs 5 tabs

the causes of government expenditure growth a survey of the u s evidence abstract the growth of government budgets can be broken down into a institutional and institutional components the former component the familiar substitution income and population public goods tax sharing effects is estimated to contribute about two fifths of the growth of u s government spending the latter component rent seeking political redistributions bureaucracy and perceptual informational impedimentia is important too but an exact imputation cannot be asserted given the state of the art in empirical public choice theory the cross effects on spending of the growth of regulation and tax preferences or tax expenditures though interesting is not pursued

sources of output fluctuations in the united states during the inter war and post war years abstract this paper attempts to decompose the sources of fluctuations in industry output into 1 an aggregate national shock 2 industry group specific shocks and 3 idiosyncratic factors the empirical methodology is the engle watson dynamic mimic model the work is motivated as an attempt to compare empirically aggregate single factor theories of the cycle with real business cycle theories emphasizing technology shocks disaggregate data from the inter war and post war periods are examined conclusions on the relative importance of the various shocks seem to be dependent on the period being considered the single index theory of the cycle seems more appropriate for the inter war period

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

co movement of public spending in the g7 abstract the size of government in the g7 countries in the last fifty years follows a common pattern see the left panel of fig 1 below it grows in the first three decades and then turns flat at the beginning of the nineties for all countries alike we highlight this common pattern in a dynamic factor model and argue that a satisfactory explanation for it would be desirable

non cooperative bargaining theory an introduction the paper provides an informal introduction to some of the main themes of the recent literature on non cooperative or sequential bargaining models it focuses in particular on the relationship between the new approach and the traditional axiomatic approach exemplified by nash bargaining theory it illustrates the new insights offered by the non cooperative approach by reference to a detailed analysis of the manner in which the presence of an outside option available to one of the parties will affect the negotiated outcome finally the difficulties which arise in extending this analysis to two person bargaining with incomplete information and to n person bargaining are discussed this is a revised version of the fourth review of economic studies lecture presented in april 1985 at the joint meeting of the association of university teachers of economics and the royal economic society held in oxford the choice of lecturer is made by a panel whose members are currently professors hahn mirrlees and nobay and the paper is refereed in the usual way this paper aims to provide an informal and elementary introduction to an approach to bargaining which has received a great deal of attention over the past few years the approach involves writing down some particular sequence of moves offers and replies to be made over time in the course of negotiations and then looking for a non cooperative equilibrium in the game thus specified in practice a perfect equilibrium or in games of incomplete information a sequential equilibrium while the approach appears at first sight to be very different in spirit from the traditional axiomatic approach in which a bargaining solution is specified by appealing to a number of general requirements which are deemed appropriate on the basis of some a priori considerations the two approaches are in fact complementary while the

macroeconomic volatility investment anemia and environmental struggles in the philippines abstract while its sacrifice of resource endowments is comparable to that of other developing countries the philippines does not have the strong record in capital accumulation and structural change of its asian neighbors a crisis prone macroeconomy traceable to a heavy dependence on volatile external finance and short sighted macroeconomic management explains the feeble rate of accumulation environmental losses can be traced both to extensive factors economic and population growth and intensive factors unequal distribution and access to market resources in the concluding section this paper examines the feasibility of an alternative macroeconomic stance which invests in environmental regeneration and accepts a lower and steadier national economic growth rate

common and country specific fluctuations in productivity investment and the current account abstract dynamic factor analysis and kalman filtering are used to construct a measure of common economic activity for the g7 countries we find that the common fluctuations are strongly associated with movements in us investment common fluctuations have substantial impact on fluctuations in both productivity and investment in these countries but very little impact on the current account country specific investment fluctuations have a significant negative impact on the current account while country specific productivity movements have little independent effect these findings are shown to be generally consistent with the predictions of a multi country dynamic model calibrated to the empirical decomposition of productivity shocks

bargaining and international environmental agreements this article surveys game theoretic papers focused on the negotiation process that leads to an international environmental agreement most of the papers considered apply bargaining theory although other approaches have been considered as well among other issues the papers considered analyze the burden sharing rule that will result from a negotiation over a global public good the role of information asymmetries the impact of unilateral commitments delegation and ratification whether or not countries are going to form groups during the negotiation process and the influence of the expectation of a future bargaining process on investment decisions the basic bargaining model is optimistic as it predicts that countries will reach an efficient agreement immediately however all the developments of this model surveyed afterwards are rather pessimistic and even the basic model has perverse incentives for pre negotiation signals

selecting permit allocation rules for agricultural pollution control a bargaining solution abstract one of the primary justifications for using transferable permits for pollution control is that they achieve a given level of emission reduction at the lowest cost although the initial allocation of pollution permits may have no impact in terms of efficiency it does have a significant impact on equity in this paper we examine a variety of permit allocation rules for a small catchment in south west england an asymmetric nash bargaining framework is employed to characterise agents co operative behaviour and to explain their likely preferences over permit allocation rules the results indicate that the preferred allocation scheme depends upon the relative bargaining power of the agents furthermore some potential links between ex ante and ex post equity criteria were also discussed

advanced economies and emerging markets dissecting the drivers of business cycle synchronization abstract what are the divers of business cycle synchronization within and between advanced and emerging economies at the sector level this question is addressed by analysing international co movements of value added growth in a multi sector dynamic factor model the model contains a world factor region factors sector factors country factors and idiosyncratic components the model is estimated using bayesian methods for 9 disaggregated sectors in 5 developed economies g5 and 19 emerging economies for the 1972 2009 period the results suggest that while there exists a common regional business cycle in the g5 fluctuations in sectoral value added growth are dominated by country specific factors in the emerging markets despite that the international factor the sum of world and sector factors is more important than the region factor suggesting that the emerging markets are more synchronized with the g5 a simple regression shows that i the world factor would be more important the larger the share of agriculture in output ii in more open economies the sector factor is more important in explaining sectoral value added growth fluctuations iii the region factors is more important the richer and the less volatile the economy finally a comparison of the variance of sectoral value added growth accounted for by each factor from the pre to the post globalization period shows convergence of the business cycles within the g5 and em respectively the changes in the contribution of the world sector and region factor are due to changes in the importance of those factors within sectors however for the emerging markets the fall in the importance of the country factors is dominated by changes in the structural composition of the economies therefore the evolution of the structural composition in the emerging markets could be an important driver for more synchronized business cycles at the regional and international level

the meta production function approach to technological change in world agriculture abstract an alternative meta production function for agriculture is estimated with the cross section data for 43 countries and three years 1960 1970 and 1980 constructed and used by kawagoe hayami and ruttan and hayami and ruttan in their studies by allowing for country specific efficiency factors and using a flexible functional form the transcendental logarithmic production function strikingly different results from those of kawagoe hayami and ruttan are obtained in particular it is found that elasticity of output with respect to machinery is variable and the degree of local returns to scale is not constant and increases with the usage of machinery

the cyclical behaviour of fiscal policy evidence from the oecd this paper addresses the topic of cyclicality in scal policy in particular we show that the level of cyclicality varies across spending categories and across oecd countries in line with leading theories of scal cyclicality we show that countries with volatile output and dispersed political power are the most likely to run procyclical scal policies wage government consumption is highlighted as the most important channel by which these variables affect scal cyclicality

the median voter model in public choice theory the changing perception by public choice theorists about the relevance of the median voter model is a result of excessive extrapolation of the conclusions of theoretical models to the real world early in the 1970s the median voter model was often accepted as implying that the output produced in the public sector was what was most preferred by the median voter this claim is excessive because the median voter model is only a model of demand aggregation under majority rule and has little to say about the supply side of the public sector in the late 1970s many scholars identified several circumstances under which the model would not apply in theory but these critiques of the model were often viewed as reasons to abandon the median voter model altogether the model went from having excessive claims that made the model appear to be more powerful than it really is to excessive claims that made the model appear to be less powerful than it really is these latter claims were often in response to the earlier claims rather than to the model appropriately applied

determinants of business cycle comovement a robust analysis abstract this paper investigates the determinants of business cycle comovement between countries our dataset includes over 100 countries both developed and developing we search for variables that are robust in explaining comovement using the approach of leamer amer econom rev 73 1983 31 variables considered are i bilateral trade between countries ii total trade in each country iii sectoral structure iv similarity in export and import baskets v factor endowments and vi gravity variables we find that bilateral trade is robust however two variables that the literature has argued are important for business cycles industrial structure and currency unions are found not to be robust

climate policy learning and technology adoption in small countries a significant reduction in global greenhouse gas emissions requires international cooperation in emission abatement as well as individual countries investment in the adoption of abatement technology the existing literature on climate policy pays insufficient attention to small countries which account for a substantial proportion of global emission in this study we investigate how climate policy and learning about climate damage affect investment in abatement technology in small countries we consider three alternative climate policy instruments emission standards harmonized taxes and auctioned permits we say that learning is feasible if an international environmental agreement iea is formed after the resolution of uncertainty about climate damage we find that either with learning and quadratic abatement costs or without learning harmonized taxes outperform emission standards and auctioned permits in terms of investment efficiency without learning a large cost of nonparticipation that a country incurs in the iea can be beneficial to the country whether learning improves investment efficiency depends on the size of this nonparticipation cost

productivity in multiple output public service a quadratic frontier function and malmquist index approach abstract the purpose of this study is to analyse the development of productivity and structural efficiency for an extended period of time 1974 to 1987 in the production of public social insurance services in sweden the analysis is based on the estimation of a deterministic flexible single input multiple output frontier production function the findings indicate a productivity decrease for the entire period from 1974 to 1987 of 18 percent in the period 1974 to 1982 productivity decreased by approximately 30 percent but at the end of the period 1984 to 1987 there was a productivity recovery of about 11 percent

the role of international factors in the business cycle a multi country study abstract empirical research has been conducted on the various theories of the business cycle over many countries however very little research has attempted to undertake a multi country disaggregate investigation into the sources of output change this paper decomposes fluctuations in industry output in a particular country into 1 a nation specific shock 2 an industry specific shock 3 a common shock and 4 an idiosyncratic factor using a dynamic factor analysis state space approach the paper finds that the industry specific impulse explains a significant but small part of the variance of the forecast error this provides limited support for the disaggregated real business cycle paradigm

the intercountry agricultural production function and productivity differences among countries abstract the sources of differences in labor productivity in agriculture between developed countries dc s and less developed countries ldc s are identified by estimating an aggregate agricultural production function based on cross county data for 1960 1970 and 1980 the production function was found to be stable over the entire period agriculture in the dc s was characterized by increasing returns and in the ldc s by constant returns to scale the results imply that unfavorable man land ratios do not represent an immediate barrier to rapid agricultural development in the low income ldc s but they may create a serious agricultural adjustment problem as those countries advance into the middle income range

on the size of u s government political economy in the neoclassical growth model we study a dynamic version of meltzer and richard s median voter model of the size of government taxes are proportional to total income and they are redistributed as equal lump sum transfers voting takes place periodically over time and each consumer votes for the tax rate that maximizes his equilibrium utility we calibrate the model to u s data key elements in the calibration are the income and wealth distribution and the parameters governing the leisure and consumption choices the total size of transfers predicted by our political economy model is quite close to the size of transfers in the data

an inquiry into the sources of macroeconomic fluctuations abstract this paper attempts to decompose the sources of fluctuations in quarterly employment by industry and region into 1 an aggregate national shock 2 region specific shocks 3 industry specific shocks and 4 idiosyncratic factors the empirical analysis is motivated by a dynamic theory of the business cycle the empirical methodology is the engle watson dynamic mimic model implemented via the em algorithm the work is motivated as an attempt to compare empirically aggregate single factor theories of the cycle with real business cycle theories emphasizing industrial or regional shocks

government debt in the euro area evidence from dynamic factor analysis abstract this paper shows that an unobserved common factor drives the co movement of government debt in the euro area the old age dependency ratio explains the factor after controlling for the maastricht treaty the adoption of the euro and the ongoing crisis

can economic activities lead to climate chaos an economic analysis on global warming this paper presents a two sector dynamic general equilibrium model in which the productivity of the agricultural sector depends on the atmospheric temperature which in turn is influenced by the activities of the manufacturing sector the equilibrium time paths of the world economy and temperature depend on the rate at which the earth sheds heat if this decay is too small the dynamic interaction between the climate system and the market mechanism both of which are stable in isolation may lead to cycles or even chaos furthermore economic growth may push the world economy and temperature from a stable stead state into a cyclical or chaotic time path

sustainability and comovement of government debt in emu countries a panel data analysis we investigate the sustainability of fiscal policy in a set of 19 european monetary union emu countries over the period 1970 2016 panel unit root tests in the presence of cross section dependence show that the government debt series is stationary indicating that the solvency condition would be satisfied for these countries this confirms the effectiveness of the austerity measures implemented by these member states moreover an unobserved common factor drives the comovement of government debt in the eurozone

the role of the reference technology in measuring productive efficiency after a twenty year lull the measurement of productive efficiency is enjoying a revival in particular the index of efficiency developed by debreu i95i and later utilised by farrell i957 has received considerable attention these measures have been used fairly extensively in empirical work in both the operations research and economic literature these types of indexes have also appeared in the growing literature on testing for regularity conditions in production e g in afriat i972 diewert and parkan i983 and varian 1984 since the farrell type measure is the focus in this paper a brief review is useful in the farrell framework overall efficiency oe can be decomposed into two multiplicative components allocative efficiency ae and technical efficiency te

international environmental agreements the case of costly monetary transfers most existing international environmental agreements to resolve transboundary pollution problems appear constrained in the sense that either monetary transfers accompany uniform abatement standards agreements based on a uniform standard with monetary transfers or differentiated abatement standards are established but without monetary transfers agreements based on differentiated standards for two asymmetric countries facing the challenge of a transboundary pollution problem we compare the relative efficiency of these two second best agreements we study especially the role of the costs associated with transfer payments across countries in the choice of these agreements to conduct this analysis we use a negotiation game and the generalized nash bargaining solution nash in econometrica 21 128 140 1953 as the equilibrium for total welfare our findings show that countries collectively prefer the uniform to the differentiated agreement if the cost of transfers is sufficiently low compared to the ratio for countries of the difference of the abatement costs between the two agreements in the analysis of individual welfare we also discuss the reluctance of one country to sign a specific type of agreement even if it is better off than in the case of non cooperation

the size and composition of government expenditure abstract this paper tests several leading hypotheses on determinants of government expenditure the purpose is to avoid omitted variables bias by testing the prominent theories in a comprehensive specification to identify persistent puzzles for the current set of theories and to explore those puzzles in greater depth by looking at the composition of government expenditure and the level of government at which it takes place as well as its magnitude using government financial statistics data from the imf covering over 100 countries from 1970 2000 i look at cross sectional and inter temporal variation in government expenditure and both individual categories of expenditure such as defense education health care and different levels of government central and local among other results i find a new explanation for wagner s law widespread evidence that preference heterogeneity leads to decentralization rather than outright decreases in expenditures that a great deal of the expenditure associated with increased trade openness is not in categories that explicitly insure for risk and evidence that both political access and income inequality affect the extent of social insurance

how strong is co movement in employment over the business cycle evidence from state sector data abstract this study measures the extent of co movement in employment across states and sectors at business cycle frequencies the strength of co movement is quantified using the cohesion measure developed by croux forni and reichlin rev econ statist 83 2001 232 the data indicate that cohesion is generally positive for the state sector pairs although the distributions mass around relatively low values the results suggest that cohesion has risen over time and that cohesion increases with spatial aggregation evidence reveals that the measured degree of co movement is sensitive to the chosen periodicity of the data and that there is much greater cohesion across states for a given sector than across different sectors within a state an investigation into the sources of cross state variation in cohesion reveals that important determinants include the share of state employment in manufacturing the different effects of monetary policy actions on each state s employment and the degree of sectoral diversity within a state

north south negotiations on emission reductions a bargaining approach this article models north south negotiations on emission reductions where the north provides side payments in exchange for the south s adoption of a more stringent emission standard we find that depending on where firms compete strong asymmetry among regions the two regions different valuations of side payments and climate change damage can produce self enforcing cooperative agreements moreover the south s optimal standard choice can be one of two polar cases i e either the cleanest or the dirtiest irrespective of the continuum of standards available the results above can also hold true when both parties bargain over the south s emission tax

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

trade interdependence and the international business cycle a stochastic general equilibrium model of the world economy is developed to analyze the contribution of trade interdependence to international business cycles we test some of the implications of the model using data from ten major industrial countries and a variety of detrending techniques to calculate the cyclical component of output we find that the significance of trade in the transmission of economic disturbances across countries is not robust to the choice of the detrending method in general the role of trade interdependence is moderate and seem to have been stronger in the period before 1973

international demand and liquidity shocks in a svar model of the australian economy a structural vector autoregressive model of the australian economy that allows for international shocks from the usa japan as well as world commodity prices is specified and estimated for the period 1979 1999 a block exogenous structure linking the three countries is imposed the international linkages are modelled using a factor structure to circumvent problems from estimating large scale dynamic models the factors are estimated recursively using a kalman filter and are found to represent aggregate demand and liquidity shocks for the usa and japan respectively the key empirical result is the usa shocks are the dominant source of international shocks on the australian economy with the japanese economy having a dampening effect on the usa shocks the empirical results also show that australian monetary policy responds to domestic conditions rather than international monetary policy

income distribution in rice growing villages during the post green revolution periods the philippine case 1985 and 1998 this paper aims to examine changes in household income sources and its impact on household income distribution in the post green revolution periods in 1985 and 1998 in the rural philippines we found that there has been a structural shift of household income away from farm in favor of nonfarm labor income sources this finding indicates that rural development is being led by nonfarm sectors such a shift has resulted in an increase in household income inequality as the distribution of nonfarm income has become less equal over time and was markedly more unequal than that of farm income in 1998

international environmental problems a simple taxonomy of international environmental problems is developed based on economic considerations the unidirectional externalities are illustrated by the case of one upstream and one downstream country the main problem in this case is an informational one the analysis of regional reciprocal externalities is illustrated by the acid rains in europe it is shown that an efficient solution could be achieved by transferable export rights finally global external problems are discussed with reference to greenhouse effects and extinction of species copyright 1990 by oxford university press

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

identifying the common component of international economic fluctuations a new approach in this paper we develop an aggregation procedure using time varying weights for constructing the common component of international economic fluctuations the methodology for deriving time varying weights is based on some stylised features of the data documented in the paper the model allows for a unified treatment of cyclical and seasonal fluctuations and also accommodates the dynamic propagation of shocks across countries we find evidence for a world business cycle as well as evidence for a distinct european common component we also find some evidence that macroeconomic fluctuations have become more closely linked across industrial economies in the period after 1973 the world economy has become more closely integrated in recent years due to increasing trade and financial flows across countries this has spurred interest in the question of how the ongoing phenomenon of globalisation has affected the transmission and propagation of business cycle fluctuations across national borders an important question in this context is whether a substantial fraction of economic fluctuations are country specific or if there exists a world business cycle which might be defined as fluctuations that are common across all countries more generally the comovement of macroeconomic aggregates across different countries has become a topic of increasing interest in both academic and policy circles these issues have implications in a number of dimensions an empirical analysis of the relative importance of country specific versus common international fluctuations is of relevance for determining the structure of certain classes of international business cycle models from a policy perspective strong comovement of output across countries at business cycle frequencies implies that external trade would be unlikely to play a significant role in dampening fluctuations domestic policies aimed at affecting the real exchange rate and thereby attempting to boost net exports in the short run would then tend to have limited impact the degree of synchronisation of business cycles across countries also has important implications for short run international policy coordination and for assessing the feasibility of monetary unions therefore identifying and analysing the common component of international economic fluctuations is relevant from a number of different perspectives

efficiency and technical change in the philippine rice sector a malmquist total factor productivity analysis regional differences in total factor productivity efficiency and technological change in the philippine rice sector are examined for the post green revolution era malmquist productivity indices were constructed for 1971 90 and were decomposed into efficiency and technological change the average annual malmquist productivity growth was only slightly positive productivity growth was negative during the early 1970s and was followed by a period of positive growth growth was negative again in the late 1980s the period of positive growth coincided with the introduction of new rice varieties while the declines are likely to have been caused by intensification of rice production in lowland farming systems certain regions such as central luzon western visayas and southern and northern mindanao had higher rates of technological change than others this may be due to higher investments in infrastructure and education increased adoption of tractors and a better agroclimatic environment

international aspects of public infrastructure investment m odelling infrastructure as an international public good in a two country m odel of trade where each country s social planner behaves strategically we show that the equilibrium levels of infrastructure are sub optimal from a global perspective utilising an appropriate econom etric fram ework and data from 16 european countries over the period 1987 95 we find evidence that accords well with the m ain predictions of our theory thus we are able to offer a plausible theoretical explanation why public capital m ay be undersupplied as suggested by previous em pirical literature
