explaining business cycles in small open economies abstract this paper analyzes the role of world price shocks fluctuations in the prices of capital intermediate and primary goods and in the world real interest rate in the generation and propagation of business cycles in small open developing countries i construct a stochastic dynamic multi sector small open economy model the model is a variant of the specific factors model and reflects the major structural characteristics of developing economies i utilize variance decomposition methods to quantitatively evaluate the impact of world price shocks the results indicate that world price shocks account for a significant fraction of business cycle variability in developing countries

technological regimes and schumpeterian patterns of innovation this paper proposes that the specific pattern of innovative activities in an industry can be explained as the outcome of different technological learning regimes a technological regime is defined by the particular combination of technological opportunities appropriability of innovations cumulativeness of technical advances and properties of the knowledge base building upon the distinction between schumpeter mark i and schumpeter mark ii industries this paper provides empirical estimates of the relationships between indicators of the schumpeterian patterns of innovation concentration of innovative activities stability in the hierarchy of innovators and importance of new innovators and indicators of the variables defining technological regimes

empirical patterns of firm growth and r d investment a quality ladder model interpretation we present a partial equilibrium model of endogenous firm growth with r d investment and stochastic innovation as the engines of growth drawing on the quality ladder models in the macro growth literature and the literature on patent races and the discrete choice models of product differentiation the model fits a number of empirical patterns well including i a skewed size distribution of firms with persistent differences in firm sizes ii firm growth independent of firm size as stated in the so called gibrat s law and iii r d investment proportional to sales

unobservable industry characteristics and the innovation concentration advertising maze evidence from an econometric study using panel data for manufacturing industries in the frg 1979 1986 in discussing the nexus between innovations and market structure it is often argued that industry characteristics called opportunities might play an important role as determinants of innovation and that simultaneity rather than one way causality prevails we consider a three equation model for innovation advertising and concentration based on pooled cross section time series data for 26 german manufacturing industries we estimate single equation models with and without fixed industry and or time effects to control for unobservable industry or time effects respectively and simultaneous equation systems including fixed effects and controlling for extreme cases outliers or not furthermore we use two different measures for innovations i e the percentage of shipments due to new products and the percentage of firms which classified themselves as innovators our results can be summarized as follows 1 the firm size has no significant effect on innovation one can therefore not conclude from this data set that large firms are more innovative than small ones 2 unobservable industry effects do matter 3 the treatment of outliers does matter 4 simultaneity does matter 5 the way innovations are measured does matter 6 different stories could be told based on the results of the systems of interdependent equations estimated

on the relationship between firm size and export intensity export marketing literature supports the view that firm size is positively related to export intensity although the empirical findings have been mixed a number of theoretical arguments are used to support this proposition i e international marketing economies of scale limited managerial and financial resources of small firms decisionmaker s risk perception based on a large survey of the italian manufacturing industry the article falsifies the proposition and challenges some widely held assumptions in export marketing literature

the relationship between firm growth size and age estimates for 100 manufacturing industries this study uses a sample of all firms operating in 100 manufacturing industries to examine some aspects of firm dynamics it finds that firm growth the variability of firm growth and the probability that a firm will fail decrease with firm age it also finds that firm growth decreases at a diminishing rate with firm size even after controlling for the exit of slow growing firms from the sample gibrat s law therefore fails although the severity of the failure decreases with firm size copyright 1987 by blackwell publishing ltd

age size growth and survival uk companies in the 1980s this paper examines growth and survival amongst quoted and unquoted u k companies in the period 1975 85 and compares the results with earlier u k and u s studies an examination of death rates shows that smaller companies had higher death rates but the largest and smallest companies were least vulnerable to takeover careful attention is therefore paid to problems of sample selection bias it is shown that smaller companies grew faster than larger companies that gibrat s law does not hold amongst smaller firms that age is negatively related to growth and that these results are not an artifact of sample selection bias copyright 1994 by blackwell publishing ltd

output movements in east asia is there a regional factor using lumsdaine and prasad s 2003 methodology to construct a measure of the common component of industrial output fluctuations with time varying weights this study finds that there is a significant regional factor that explains the movement in industrial production output across countries in east asia asean 5 3 the cumulated common component for east asia has very distinct peaks and troughs with turning points occurring about every three years shocks in 2000 2001 coinciding with the bursting of the it bubble appear to be very important as there is a very large decline in the common component of industrial production output larger than that experienced during the 1997 asian financial crisis similar to mckinnon and schnabl s 2003 findings the japanese economy is important for the region as its industrial production output cycle has the largest weight in the construction of the cumulated common component for the region and appears to be the most similar to it nevertheless china s asymmetry with the cumulated component for the region appears to have been beneficial for the region especially in the most recent period

the investment decision a re examination of competing theories using panel data in the united states gross business fixed investments constitute about 10 percent of the gross national product gnp such investments may represent gnp s most important component because a plant and equipment have a long term effect on the economy s productive capacity b changes in investment spending directly affect employment levels and workers incomes in durable goods industries and c supply and demand are sensitive to investment changes economists have long been concerned about what determines capital spending investments using data for us manufacturing firms for 1972 90 the author compares five investment theories accelerator theory cash flow theory neoclassical theory modified neoclassical theory and q theory if the results for cross section regressions can be viewed as representing the long term equilibrium the single most important determinant of capital spending appears to be cash flow apparently managers care more about cash flow and cost of capital than about stock market signals and the level of output and at the firm level managerial perceptions about fundamentals are more important that market perceptions for managers the stock market may be a side show to capital spending decisions to generalize in a way useful for developing countries firm level financial decisions are closely linked to real decisions in the economy internal finance is the most important use of funds so there is a close relationship between real and financial decisions

the relationship between firm growth and labor demand several american studies have recently estimated models of employment growth from longitudinal data sets of business firms evans 1987 leonard 1986 hall 1987 by and large these studies find that the growth rate of employment is inversely correlated with initial size measured by employment and with age young firms tend to grow more rapidly than old ones these studies have cast considerable doubt on gibrat s law or the assumption of independence between firm size and the rate of growth however departures from gibrat s law are modest especially among firms above minimum size recently a group of researchers has proceeded along similar lines of investigation using data from a panel of italian manufacturing firms located in northern italy the purpose of this paper is to compare our results with those obtained for the u s and to explore in more detail the soundness of this approach our results are similar to the abovementioned american studies we find that departures from gibrat s law are not large

schumpeterian patterns of innovation using patent data for four countries germany france united kingdom and italy for the period 1968 1986 the authors find that the patterns of innovative activities differ systematically across technological classes while remarkable similarities emerge across countries in the patterns of innovative activities for each technological class this result strongly suggests that technological imperatives and technology specific factors closely linked to technological regimes play a major role in determining the patterns of innovative activities across countries schumpeter proposed two major patterns of innovative activities the first one labelled by nelson and winter 1982 and kamien and schwartz 1982 as schumpeter mark i is proposed in the theory of economic development 1934 in this work schumpeter examined the typical european industrial structure of the late nineteenth century characterised by many small firms according to this view the pattern of innovative activity is characterised by technological ease of entry in an industry and by a major role played by new firms in innovative activities new entrepreneurs come in an industry with new ideas new products or new processes launch new enterprises which challenge established firms and thus continuously disrupt the current ways of production organisation and distribution and wipe out the quasi rents associated with previous innovations the second one labelled schumpeter mark ii is proposed in capitalism socialism and democracy 1942 in this work inspired by the features of the american industry of the first half of the twentieth century schumpeter discussed the relevance of the industrial r d laboratory for technological innovation and the key role of large firms according to this view the pattern of innovative activities is characterised by the prevalence of large established firms and by relevant barriers to entry for new innovators large firms have institutionalised the innovation process with the creation of r d laboratories filled with researchers technicians and engineers with their accumulated stock of knowledge in specific technological areas their advanced competence in large scale r d projects production and distribution and their relevant financial resources they create barriers to entry to new entrepreneurs and small firms

synchronized business cycles in east asia and fluctuations in the yen dollar exchange rate because many authors have proposed stimulating the ailing japanese economy by monetary expansion and yen depreciation we explore the repercussions of depreciating the yen against the dollar on the other east asian economies which largely peg to the dollar since 1980 economic integration among japan s neighbors china hong kong indonesia korea malaysia philippines singapore and thailand has intensified and except for china their business cycles have been highly synchronized these cycles have been closely linked to fluctuations in the yen dollar exchange rate through changes in their export competitiveness and inflows of foreign direct investment we show that a major yen devaluation would have a negative impact on incomes in other east asian economies and that it is not a sensible policy option for japan

how does globalization affect the synchronization of business cycles this paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries the results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles the evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries one striking result is that on average cross country consumption correlations have not increased in the 1990s precisely when financial integration would have been expected to result in better risk sharing opportunities especially for developing countries this abstract was borrowed from another version of this item

changes in concentration turbulence and the dynamics of market shares most previous studies of the dynamics of industry structure by emphasizing changes in concentration conceal much of the nature of underlying competitive processes here we employ a stochastic fir

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

testing a model of exploration and exploitation as innovation strategies we suggest a structural model that specifies firm growth as a function of firm specific parameters market specific parameters and competition for purchasing power the model distinguishes between two firm innovation strategies exploration and exploitation on the basis of a set of simulations of this model we derive a number of empirically testable hypotheses a subset of these have already found support in the empirical literature we take these as evidence in favor of the explanatory power of the model in addition we are able to derive further testable propositions on the interaction of firm demographic processes innovative behavior and market structure that go beyond the existing literature and that we suggest for further research we conclude that the approach chosen here provides a fruitful pathway for further research

schumpeterian patterns of innovation are technology specific this paper examines the patterns of innovative activities at the technological and country levels using patent data for 49 technological classes in six countries usa japan germany france united kingdom and italy it is shown that the patterns of innovative activities differ systematically across technological classes but are remarkably similar across countries for each technological class in particular two groups of technological classes are identified schumpeter mark i and schumpeter mark ii in these two groups innovative activities are structured and organized in different ways the first represents a widening pattern concentration of innovative activities is low innovators are of small economic size stability in the ranking of innovators is low and entry of new innovators is high the second represents a deepening pattern concentration of innovative activities is higher than in the first group innovators are of larger economic size stability in the ranking of innovators is greater and entry is lower the former group comprises mechanical technologies and traditional sectors while the latter includes chemicals and electronics this result suggests that technology related factors such as technological regimes defined in terms of conditions of opportunity appropriability cumulativeness and properties of the knowledge base play a major role in determining the specific pattern of innovative activities of a technological class across countries within these constraints country specific factors introduce differences across countries in the pattern of innovative activities for a specific technological class finally the relationships between the specific features of the patterns of innovative activities and international technological specialization are examined technological advantages appear in general to be linked to higher degrees of asymmetries among innovators higher stability of the ranking of innovators smaller economic size of the innovating firms and lower entry rates of new innovators these relationships however are different in the two groups of technological classes in schumpeter mark i widening technological classes international technological specialization is associated with relatively higher degrees of asymmetries among innovators and entry of new innovators as well as smaller firm size while in schumpeter ii deepening technological classes international technological specialization is linked to the existence of a stable but competitive core of persistent innovators

business cycles in developing countries are they different abstract this paper demonstrates that developing countries differ considerably from their developed counterparts when focus is on the nature and characteristics of short run macroeconomic fluctuations cycles are generally shorter and the stylized facts of business cycles across countries are more diverse than those of the rather uniform industrialized countries supply side models are generally superior in explaining changes in output but a one size fits all approach in formulating policy is inappropriate our results also illustrate the critical importance of understanding business regularities as a stepping stone in the process of designing appropriate stabilization policy and macroeconomic management in developing countries

stock market and investment the signaling role of the market the author examines the role of the stock market as a signal to managers in undertaking capital expenditures he concludes that while both managerial and market perceptions are integral managerial perception is of greater importance the evidence suggeststhat as a statistic the q ratio is not sufficient to explain firms capital expenditure decisions thus the standard q model of investment should be modified to provide a more meaningful description of a firm s capital spending decisions overall the results suggest that stock market activity has only limited implications for the economy s resource allocation process evidence for the q theory of investment confirms previous findings in the literature that the model s poor empirical perfomance was partly the result of using aggregate data for the whole economy also since market perception plays only a limited role in determining capital expenditures shareholder myopia is unlikely to result in managerial myopia the implications for developing countries are while the stock market may not be central to a firm s capital spending decisions it is not a sideshow either the market plays an important signaling role for managers this is a powerful rationale for financial reform and capital development in developing countries the results also suggest that complaints that stock market activity leads to misallocation of resources may be exaggerated

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
