a history friendly model of the successive changes in industrial leadership and the catch up by latecomers abstract successive changes in industrial leadership between both firms and countries described here as catch up cycles have been common in several sectors this article develops a history friendly model to explore the role played by technological conditions in the emergence of such leadership changes the model is inspired by two cases where the emergence of disruptively novel technology played an important role mobile phones and semiconductors in the baseline setting the model is able to generate the benchmark case of three cycles with two leadership changes in particular the simulation analysis reveals that a the more disruptive the new technology and the lower the incumbents capabilities the greater the shake up of market shares between incumbents and latecomers b leadership change is more likely to occur when it coincides with certain responses by the actors to the technological disruption such as a high lock in behaviour on the part of incumbents and c a technology driven change of industrial leadership is more likely to occur in the presence of increasing returns to technological investments the counterfactual experiments show that different catch up dynamics can emerge depending on the magnitude of technological disruption the degree of lock ins the shape of technological landscape and incumbents initial capabilities in particular four other types of catch up cycle are generated the aborted cycle persistent leadership return of the old leadership and coexistence in leadership between latecomers and incumbents each of these cycles is identified with a specific historical case of catch up

catch up cycles and changes in industrial leadership windows of opportunity and responses of firms and countries in the evolution of sectoral systems this study proposes a framework that aims to explain why successive changes in industry leadership called also the catch up cycle occur over time in a sector in catch up cycles latecomer firms and countries emerge as international leaders whereas incumbents lose their previous positions new leaders are then dethroned by newcomers to identify factors at the base of catch up cycles this article adopts a sectoral system framework and identifies windows of opportunity that may emerge during the long run evolution of an industry this study proposes three windows related to the specific dimensions of a sectoral system one dimension is related to changes in knowledge and technology the second dimension pertains to changes in demand and the third includes changes in institutions and public policy the combination of the opening of a window technological demand or institutional policy and the responses of firms and other components of the sectoral system of the latecomer and incumbent countries determines changes in industrial leadership and catch up sectors differ according to the type of windows that may open and the responses of firms and other components of systems empirical evidence of catch up cycles is presented from six sectors namely mobile phones cameras semiconductors steel mid sized jets and wines

rational heuristics expectations and behaviors in evolving economies with heterogeneous interacting agents we analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent based model populated by heterogeneous interacting firms agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change imperfect information coordination hurdles and structural breaks in these circumstances we find that neither individual nor macroeconomic dynamics improve when agents replace myopic expectations with less naive learning rules our results suggest that fast and frugal robust heuristics may not be a second best option but rather rational responses in complex and changing macroeconomic environments jel c63 d8 e32 e6 o4

successive changes in leadership in the worldwide mobile phone industry the role of windows of opportunity and firms competitive action abstract we take a historical perspective to gain insight into the determinants of changes in industrial leadership in the global mobile phone industry from the beginning of the 1980s to 2012 the theoretical foundation of our analysis is a the concept of windows of opportunity proposed by industry evolution studies i e changes in the technological regulatory and consumer demand environment offering latecomers the opportunity to overtake leading rivals and b the concept of action aggressiveness proposed by the competitive dynamics literature i e the extent to which a firm forcefully takes a large number and a wide variety of actions to outperform its competitors we show that the potential for leadership changes is greater for firms that are able to undertake aggressive competitive actions at the time when significant windows of opportunity are open in particular we analyze the determinants of two leadership changes 1 in the second half of the 1990s when the us giant motorola lost its number one position dethroned by its finnish competitor nokia and 2 in the first half of the 2010s when samsung of south korea caught up with nokia

technology structural change and bop constrained growth a structuralist toolbox the latin american structuralism las is a significant part of the heterodox tradition in the theory of long run growth with a focus on the problems of developing economies which started their industrialization process when other regions had already accumulated substantial technological capabilities the emergence of a centre periphery system posed specific problems to growth and distribution in laggard economies which las discusses in a systematic way in this paper we presented a simple model which firstly captures key insights of the las school such as the persistency of technological asymmetries and structural heterogeneity secondly it can be used to analyze the impacts of shocks and policies based on how they affect supply side and demand side parameters of the model thirdly it links more closely post keynesian macroeconomics based on the bop constraint with the evolutionary microeconomics concerned with the dynamics of learning lastly it can be used as a toolbox and a teachable model in the analysis of the interactions between structural change technological catching up and long run growth

preconditions windows of opportunity and innovation strategies successive leadership changes in the regional jet industry abstract we analyse the drivers of two successive leadership changes in the regional or mid sized jet market a particularly dynamic segment of the commercial aircraft industry in the first instance bombardier a canadian newcomer assumed leadership over the incumbents bae and fokker in 1995 in 2005 the brazilian firm embraer became the market leader in terms of number of regional jet deliveries our theoretical framework considers discontinuities in the building blocks of sectoral innovation systems as windows of opportunity for which challenger firms can devise strategic responses allowing them to assume market leadership it also considers preconditions as necessary capabilities limiting the number of potential challenger companies the analysis of leadership change shows that more efficient engines and technological improvements in subsystems changing oil prices business cycles liberalization of air transport services scope clauses and government interventions provided technological demand and regulatory windows of opportunity launching new aircraft families an architectural innovation targeting the 50 and the 100 120 seat niche markets gave first bombardier s crj family and later embraer s e jet family the leadership the fate of failed challengers and incumbents point to the importance of incumbent traps technological and financial capabilities the timing of windows of opportunity speedy strategic response a proper evaluation of future demand and sheer luck as long lead times and sunk costs entrap incumbents and other inadequately responding companies

technological capabilities and industrialization abstract this paper reviews the implications for industrial strategy of recent research on technological capabilities at the firm and national levels after exploring the nature and determinants of microlevel technological development a simple framework for explaining the growth of national capabilities is set out based on the interplay of incentives capabilities and institutions each may suffer market failure and so require corrective intervention the experience of some industrializing countries is described to assess the validity of this framework it is concluded that interventions carefully and selectively applied are necessary for industrial success

what makes growth sustained abstract we identify structural breaks in economic growth in 140 countries and use these to define growth spells periods of high growth preceded by an upbreak and ending either with a downbreak or with the end of the sample growth spells tend to be shorter in african and latin american countries than elsewhere we find evidence that growth duration is positively related to the degree of equality of the income distribution democratic institutions export orientation with higher propensities to export manufactures greater openness to fdi and avoidance of exchange rate overvaluation favorable for duration and macroeconomic stability

fiscal and monetary policies in complex evolving economies what is the most appropriate combination of fiscal and monetary policies in economies subject to banking crises and deep recessions we study this issue using an agent based model that is able to reproduce a wide array of macro and micro empirical regularities simulation results suggest that policy mixes associating unconstrained counter cyclical fiscal policy and monetary policy targeting employment is required to stabilise the economy we also show that discipline guided fiscal rules can be self defeating as they depress the economy without improving public finances finally we find that the effects of monetary and fiscal policies become sharper as the level of income inequality increases

technological regimes catching up and leapfrogging findings from the korean industries abstract this paper examines the experiences of selected industries in korea to identify the stylized facts in the process of technological capability building and thereby to sort out the conditions for the catching up to occur to explain the process we have built a model of technological and market catching up a special attention has been given to the question of whether there has been a case of leapfrogging in any industry in korea and if so what are the conditions for its incidence in our framework we first measure the degree of catching up in terms of market shares in the world then we focus on catching up in technological capabilities in explaining the different record and prospects of korean industries in market catching up in the model technological capability is determined as a function of both technological effort and the existing knowledge base as determinants of technological effort we look at the technological regimes of the industries such as cumulativeness of technical advances fluidity predictability of technological trajectory and the properties of knowledge base using this model we explain the different technological evolution of the selected industries in korea including the d ram automobile mobile phone consumer electronics personal computer and machine tool industries we find three different patterns of catching ups path creating catching up cdma mobile phone path skipping catching up d ram and automobile and path following catching up consumer electronics personal computers and machine tools we interpret the first two case of catching up as leapfrogging unlike the argument by perez and soete perez c soete l 1988 catching up in technology entry barriers and windows of opportunity in dosi et al eds technical change and economic theory pinter publishers london we find that important r d projects except automobiles where only private r d was involved involved both private and public capacities and that entry was not driven by endogenous generation of knowledge and skills but by collaboration with foreign companies

economies of scale in the korean district heating system a variable cost function approach this paper aims to investigate the cost efficiency of south korea s district heating dh system by using a variable cost function and cost share equation we employ a seemingly unrelated regression model with quarterly time series data from the korea district heating corporation kdhc a public utility that covers about 59 of the dh system market in south korea over the 1987 2011 period the explanatory variables are price of labor price of material capital cost and production level the results indicate that economies of scale are present and statistically significant thus expansion of its dh business would allow kdhc to obtain substantial economies of scale according to our forecasts vis a vis scale economies the kdhc will enjoy cost efficiency for some time yet to ensure a socially efficient supply of dh it is recommended that the kdhc expand its business proactively with regard to informing policy or regulations our empirical results could play a significant role in decision making processes

innovation diversity and diffusion a self organisation model a number of features of innovation diffusion are identified appropriability diversity expectations selection learning and spillover externalities a dynamic model is formul ated to embed the diffusion question into a more general framework of disequilibrium competition the model incorporates distinct vintage structures reflecting a change in technological trajectory learning by using a nd expectations driven investment rules of thumb simulation studies reveal robust quasi logistic curves but a complicated pattern of net market share gains and losses uncertainty regarding the rationality of early or late adoption it is argued ensures that the requisite behavioral variety is present to generate these diffusion patterns copyright 1988 by royal economic society

gradual catch up and enduring leadership in the global wine industry the wine industry is an extremely interesting sector from a catch up point of view because the latecomers in the international market have changed how wine is produced sold and consumed and in doing so they have challenged the positions of incumbents until the end of the 1980s the european countries and particularly france and italy dominated the international market for wine subsequently significant changes in the market namely decreases in consumption by traditional consuming countries the entry of new inexperienced consumers and the increasing importance of large distribution have threatened this supremacy initially the usa and australia and later emerging countries such as chile and south africa gained increasing market shares in both exported volumes and value at the expense of incumbents however some of these newcomers e g australia have shown slower growth opening opportunities for newer entrants such as argentina and new zealand at the same time some of the incumbents especially italy have innovated challenging the leadership of france in key markets such as the usa in this article we investigate the different catch up cycles in the global wine sector that occurred between the 1960s and 2010 through a detailed analysis of export volumes values and unit prices we address issues related to the increasing share in the global market of latecomer countries and the relative decline of the incumbents as well as possible changes in the market leadership within these two groups

public policy and catching up by developing countries in global industries a simulation model this paper examines the effects of different public policies strengthening capability building favouring firms learning protectionism and support of entry of new domestic firms on the catch up of a latecomer with respect to an incumbent country in changing and uncertain technological environments the effects of these policies are analysed with a simulation model first separately and then jointly to assess possible complementarities we reach several results first we confirm that capability building and firms learning are important drivers of catch up second we find that when a large technological discontinuity takes place entry support favours catch up while protectionism has the opposite effect protectionism favours catch up only when no technological discontinuity opens up third we find that depending on the technological conditions different policy complementarities exist therefore different policy mixes should be at the base of a country catch up strategy these results add to the previous literature on public policy and catching up by developing countries in an industry by distinguishing the different effects of various types of public policy and relating them to the technological conditions that are present in an industry

when more flexibility yields more fragility the microfoundations of keynesian aggregate unemployment abstract wages are an element of cost crucially affecting the competitiveness of individual firms but the wage bill is also a crucial element of aggregate demand hence it could be that more flexible and fluid labour markets while allowing for faster inter firm reallocation of labour may also render the whole economic system more fragile more prone to recession and more volatile in this work we investigate some conditions under which such a conjecture applies the paper presents an agent based model that investigates the effects of two archetypes of capitalism in terms of regimes of labour governance defined by the mechanisms of wage determination firing labour protection and productivity gains sharing upon i labour market regularities and ii macroeconomic dynamics long term rates of growth gdp fluctuations unemployment rates inequality etc the model is built upon the keynes meets schumpeter family of models dosi et al 2010 explicitly incorporating different microfounded labour market regimes our results show that seemingly more rigid labour markets and labour relations are conducive to coordination successes leading to higher and smoother growth

on the measurement of capacity utilization capacity utilization is usually defined as the ratio of actual output to the output corresponding to 1 the minimum point on the short run average total cost curve and 2 the point of tangency between the long run average total cost and short run average total cost curves in practice however capacity utilization is often measured as the ratio of actual to the maximum potential output consistent with a given capital stock this paper demonstrates how to estimate the theoretical measures of capacity utilization and examines the correlation between three measures of capacity utilization and the mcgraw hill estimates of capacity utilization using data from a sample of u s privately owned electric utilities for 1961 83 copyright 1989 by blackwell publishing ltd

what if supply side policies are not enough the perverse interaction of flexibility and austerity abstract in this work we develop a set of labour market and fiscal policy experiments upon the labour and credit augmented schumpeter meeting keynes agent based model the labour market is declined under two institutional variants the fordist and the competitive set ups meant to capture the historical transition from the post wwii toward the post thatcher reagan period inside these two regimes we study the different effects of supply side active labour market policies almps vs demand management passive labour market ones plmps in particular we analyse the effects of almps aimed at promoting job search and at providing training to unemployed people next we compare the effects of these policies with unemployment benefits meant to sustain income and therefore aggregate demand considering the burden of unemployment benefits in terms of the public budget we link such provision with the objectives of the european stability and growth pact our results show that i an appropriate level of skills is not enough to sustain growth when workers face adverse labour demand ii supply side policies are not able to reverse the negative interaction between flexibility and austerity iii plmps outperform almps in reducing unemployment and workers skill deterioration and iv demand management policies are better suited to mitigate inequality and to sustain long run growth

institutions foreign direct investment and domestic investment crowding out or crowding in studies of the relationship between fdi and domestic investment reach contradictory findings we argue that some of the conflicting evidence may be explained by the use of poor proxies for the theoretical concepts and questionable methodological choices we review the paper of morrissey and udomkerdmonkol published in this journal in 2012 improvements in the construction of the proxies and refinements in the estimation methodology reverse the finding of morrissey and udomkerdmonkol that fdi inflows crowd out domestic investment furthermore there is no strong evidence that good governance actually encourages domestic investment

helping infant economies grow foundations of trade policies for developing countries conventional wisdom has it that trade enhances economic efficiency and thus promotes growth at least since robert m solow s 1957 pioneering work however technological progress has been recognized as the dominant factor in determining the rate of growth this is presumably even more true for developing countries for which the possibilities of closing the knowledge gap with advanced industrial countries offers especially large growth potential we examine the impact of trade restrictions in economies in which technological spillovers within countries and across industries are fundamental to the process of growth see kenneth j arrow 1962a 1962b paul m romer 1986 stiglitz 1987 since that work it has been clear that markets by themselves do not necessarily or in general lead to overall dynamic efficiency and that there are often trade offs between static inefficiencies e g associated with patent protection and long term growth we find here in particular that the dynamic benefits of broad trade restrictions may outweigh their static costs our analysis provides the basis of an infant economy as opposed to an infant industry argument for protection this paper develops a simple two sector model with an industrial modern and a traditional craft or agricultural sector there are four key features to the model a there are spillovers from the industrial sector to the craft sector for which firms in the industrial sector are not compensated b such spillovers are geographically based that is it is only productivity increases in the industrial sector in the developing countries that affect productivity increases in the traditional sector c innovations are concentrated in the industrial sector and d size is among the important determinants of the pace of innovation in the industrial sector earlier critiques of trade policies encouraging the development of the industrial sector in developing countries ignored these spillovers they argued in effect that korea would always have a comparative advantage in growing rice therefore it was foolish for it to try to restrict imports of industrial goods even if by so doing productivity in the industrial goods sector was increased it could never catch up so the protection would have to be permanent year after year the country would have been better off if it simply specialized in its own comparative advantage growing rice korea could and did catch up however at least in certain areas if catch up is possible then dynamic comparative advantage differs from static comparative advantage but even if korea s comparative advantage remained in agriculture industrial protection might be desirable because by supporting it one might have a more dynamic agricultural traditional sector trade restrictions enhance the size of the industrial sector the benefits spill over to the rural sector and national income grows at a possibly far faster pace after presenting the model we explain why the underlying hypotheses are plausible and argue that the model is broadly consistent with historical experience and empirical evidence

the footprint of evolutionary processes of learning and selection upon the statistical properties of industrial dynamics evolutionary theories of economic change identify the processes of idiosyncratic learning by individual firms and of market selection as the two main drivers of the dynamics of industries are such processes able to account for the statistical regularities which industrial structures and dynamics display in this work we address this question by means of a simple multi firm model formalizing the mechanisms of learning and selection as such despite its simplicity the model is able to robustly reproduce an ensemble of empirical stylized facts including ample heterogeneity in productivity distributions persistent market turbulence and fat tailed distribution of growth rates

income distribution credit and fiscal policies in an agent based keynesian model this work studies the interactions between income distribution and monetary and fiscal policies in terms of ensuing dynamics of macro variables gdp growth unemployment etc on the grounds of an agent based keynesian model the direct ancestor of this work is the keynes meeting schumpeter formalism presented in dosi et al 2010 to that model we add a banking sector and a monetary authority setting interest rates and credit lending conditions the model combines keynesian mechanisms of demand generation a schumpeterian innovation fueled process of growth and minskian credit dynamics the robustness of the model is checked against its capability to jointly account for a large set of empirical regularities both at the micro level and at the macro one the model is able to catch salient features underlying the current as well as previous recessions the impact of financial factors and the role in them of income distribution we find that different income distribution regimes heavily affect macroeconomic performance more unequal economies are exposed to more severe business cycles fluctuations higher unemployment rates and higher probability of crises on the policy side fiscal policies do not only dampen business cycles reduce unemployment and the likelihood of experiencing a huge crisis in some circumstances they also affect positively long term growth further the more income distribution is skewed toward profits the greater the effects of fiscal policies about monetary policy we find a strong non linearity in the way interest rates affect macroeconomic dynamics in one regime with low rates changes in interest rates are ineffective up to a threshold beyond which increasing the interest rate implies smaller output growth rates and larger output volatility unemployment and likelihood of crises

global value chains meet innovation systems are there learning opportunities for developing countries summary the innovation systems is literature tends not to emphasize the crucial impact of international knowledge and innovation exchange and collaboration through for example inter firm and intra firm networks and global value chains gvc in developing countries this aspect is crucial with integration in gvc playing a growing and very important role in accessing knowledge and enhancing learning and innovation however there is no agreement in the literature about how innovation systems and gvc interact and how this interaction is likely to affect enterprise learning three main conclusions emerge from the theoretical analysis and evidence presented in this paper first learning mechanisms can vary widely within the various forms of governance of gvc they can be the result of the pressure to achieve international standards or be facilitated by direct involvement of the value chain leaders when the suppliers competence is low and the risk of failure to comply is high when the competences of the actors in the value chain are complementary learning is mutual and is based on intense face to face interactions second as we open is to foreign sources of knowledge the relationship between gvcs and is is nonlinear and endogenous and mutually affecting on the basis of our model we would expect a well structured and efficient innovation system would help to reduce transaction complexity and enable transactions based on relational forms of gvc governance third the internal governance of gvc is a dynamic phenomenon that is subject to continuous adjustments and changes and the nature of the is affects this co evolution 2011 elsevier ltd all rights reserved

rise of latecomers and catch up cycles in the world steel industry abstract this study analyzes the sources of changes in industrial leadership and catch up by latecomers in the world steel industry since world war ii the shift of leadership from the united states to japan in 1980 and the subsequent rise of korea with posco s output surpassing that of nippon steel in 1998 is explained on the basis of a single theoretical framework we rely on the neo schumpeterian concepts of sectoral innovation systems and windows of opportunity for latecomers in catching up with leading countries these windows include changing generations of technologies business cycles and demand shifts and government regulations and other interventions japan realized a path creating catch up by taking advantage of the opportunity window associated with the emergence of new technologies entering as a state owned enterprise posco engaged in stage skipping catch up by utilizing the downturn as a window of opportunity to pay low prices for expanding its facilities and updating its technologies

comparative analysis of firm demographics and survival evidence from micro level sources in oecd countries in this paper we present cross country evidence on firm size distribution firm demographic and post entry performance for 10 oecd countries we use harmonized firm level data drawn from business registers or social security records these data enable international comparisons and the identification of idiosyncratic country effects while average firm size differs across countries due to both sectoral specialization and within sector characteristics we find similar degrees of firm churning across countries in most of them about 20 of firms enter and exit most markets every year and about 20 40 of entering firms fail within the first 2 years of life however post entry growth of successful entrants is much higher in the usa than in europe which may be indicative of barriers to firm growth as opposed to barriers to entry

revealed distributional preferences individuals vs teams we compare experimentally the revealed distributional preferences of individuals and teams in allocation tasks we find that teams are significantly more benevolent than individuals in the domain of disadvantageous inequality while the benevolence in the domain of advantageous inequality is similar across decision makers a consequence for the frequency of preference types is that while a substantial fraction of individuals is classified as inequality averse this type disappears completely in teams spiteful types are markedly more frequent among individuals than among teams on the other hand by far more teams than individuals are classified as efficiency lovers

economic development as self discovery in the presence of uncertainty about what a country can be good at producing there can be great social value to discovering costs of domestic activities because such discoveries can be easily imitated we develop a general equilibrium framework for a small open economy to clarify the analytical and normative issues we highlight two failures of the laissez faire outcome there is too little investment and entrepreneurship ex ante and too much production diversification ex post optimal policy consists of counteracting these distortions to encourage investments in the modern sector ex ante but to rationalize production ex post we provide some informal evidence on the building blocks of our model

market opening and third party access in district heating networks the purpose of this paper is to analyse the possible effects of introducing tpa in district heating networks by identifying and scrutinizing a number of possible scenarios for increased competition the analysis builds on a theoretical discussion of economic efficiency in district heating operations and the possible impacts on consumer prices of a market opening an important conclusion is that regulated tpa may have small positive effects on competition and at the same time it can have a negative impact on the possibility to run the integrated district heating operations in a cost effective manner this conclusion stems in part from the observation that most district heating networks are local in scope moreover district heating operations are highly interdependent in for instance that the level of the return temperature of the water will affect the efficiency of combined heat and power plants for these reasons the introduction of the so called single buyer model or perhaps even more preferable an extended and more transparent producer market could represent more efficient market designs moreover in networks with clear natural monopoly characteristics an ex ante price regulation must be considered

public policies and the art of catching up matching the historical evidence with a multicountry agent based model in this paper we study the effects of industrial policies on international convergence using a multi country agent based model which builds upon dosi et al 2019b the model features a group of microfounded economies with evolving industries populated by heterogeneous firms that compete in international markets in each country technological change is driven by firms activities of search and innovation while aggregate demand formation and distribution follows keynesian dynamics interactions among countries take place via trade flows and international technological imitation we employ the model to assess the different strategies that laggard countries can adopt to catch up with leaders market friendly policies industrial policies targeting the development of firms capabilities and rd protectionist policies focusing on tariffs only we find that markets cannot do the magic in absence of government interventions laggards will continue to fall behind on the contrary industrial policies can successfully drive international convergence among leaders and laggards while protectionism alone is not necessary to support catching up and countries get stuck in a sort of middle income trap finally in a global trade war where developed economies impose retaliatory tariffs both laggards and leaders are worse off and world productivity growth slows down

faraway so close coupled climate and economic dynamics in an agent based integrated assessment model abstract in this work we develop an agent based model that offers an alternative to standard computable general equilibrium integrated assessment models iams the dystopian schumpeter meeting keynes dsk model is composed of heterogeneous firms belonging to capital good consumption good and energy sectors production and energy generation lead to greenhouse gas emissions which affect temperature dynamics climate damages are modelled at the individual level as stochastic shocks hitting workers labour productivity energy efficiency capital stock and inventories of firms in that aggregate damages emerge from the aggregation of losses suffered by heterogeneous interacting and boundedly rational agents the model is run focusing on a business as usual carbon intensive scenario consistent with a representative concentration pathway 8 5 we find that the dsk model is able to account for a wide ensemble of micro and macro empirical regularities concerning both economic and climate dynamics simulation experiments show a substantial lack of isomorphism between the effects of micro and macro level shocks as it is typical in complex system models in particular different types of shocks have heterogeneous impact on output growth unemployment rate and the likelihood of economic crises pointing to the importance of the different economic channel affected by the shock overall we report much larger climate damages than those projected by standard iams under comparable scenarios suggesting possible shifts in the growth dynamics from a self sustained pattern to stagnation and high volatility and the need of urgent policy interventions

economic complexity conceptual grounding of a new metrics for global competitiveness abstract the availability of data corresponding to the products exported by all countries provides an excellent dataset to test economic ideas and extracts new information about the process of economic development the matrix of countries and exported products shows a marked triangular structure instead of the block diagonal structure expected from ricardian arguments of specialization this observation points to the fact that diversification is instead the dominant effect in the globalized market we discuss how to define a suitable non monetary metrics for the value of diversification and the effective complexity of products we discuss in detail the previous proposed approaches to assess this challenge and their limitations we introduce a new approach to the definition of these metrics which seems to overcome the previous problems and we test it in a series of model systems

rejoinder natural monopoly and the bell system response to charnes cooper and sueyoshi our study of the bell system cost function shows that it is possible to reject the hypothesis that at t was a natural monopoly our study is based on a regression analysis of a translog cost function estimated on 1947 1977 data charnes cooper and sueyoshi charnes a w w cooper t sueyoshi 1988 a goal programming constrained regression review of the bell system breakup management sci 34 1 26 claim that they reverse our conclusion when they use goal programming estimators of a translog cost function estimated on exactly the same data that we use this claim is false there is no basis for comparing our estimates with their estimates because they in fact use different data than we use and estimate a different cost function than we estimate moreover when goal programming estimates and regression estimates based on the same data and similar cost function specifications are compared they yield similar estimates and produce the same inference about natural monopoly

municipal water supply and sewage treatment costs prices and distortions municipal water supply and sewage treatment utilities in ontario canada are studied in order to establish their costs of supply and evaluate their pricing practices prices charged to residential and commercial customers are found to be only one third and one sixth of the estimated marginal cost for water supply and sewage treatment respectively for example the average price to residential customers is 0 32m superscript 3 while the estimated marginal cost is 0 87 m superscript 3 the estimated cost parameters are combined with estimated residential and nonresidential demands functions in order to calculate approximate welfare losses that arise from overconsumption

causes and consequences of hysteresis aggregate demand productivity and employment in this work we develop an agent based model where hysteresis in major macroeconomic variables e g gross domestic product productivity unemployment emerges out of the decentralized interactions of heterogeneous firms and workers building upon the schumpeter meeting keynes family of models cf in particular dosi et al 2016b 2017c we specify an endogenous process of accumulation of workers skills and a state dependent process of firms entry indeed hysteresis is ubiquitous however this is not due to market imperfections but rather to the very functioning of decentralized economies characterized by coordination externalities and dynamic increasing returns so contrary to the insider outsider hypothesis blanchard and summers 1986 the model does not support the findings that rigid industrial relations may foster hysteretic behavior in aggregate unemployment on the contrary this contribution provides evidence that during severe downturns and thus declining aggregate demand phenomena like decreasing investment and innovation rates skills deterioration and declining entry dynamics are better candidates to explain long run unemployment spells and reduced output growth in that more rigid labor markets may well dampen hysteretic dynamics by sustaining aggregate demand thus making the economy more resilient

the national system of innovation in historical perspective contrary to some recent work on so called globalisation this paper argues that national and regional systems of innovation remain an essential domain of economic analysis their importance derives from the networks of relationships which are necessary for any firm to innovate whilst external international connections are certainly of growing importance the influence of the national education system industrial relations technical and scientific institutions government policies cul tural traditions and many other national institutions is fundamental the historical examples of germany japan and the former ussr illustrate this point as well as the more recent contrast between east asian and latin american countries introduction the national system of friedrich list according to this author s recollections the first person to use the expression national system of innovation was bengt ake lundvall and he is also the editor of a highly original and thought provoking book 1992 on this subject however as he and his colleagues would be the first to agree and as lundvall himself points out the idea actually goes back at least to friedrich list s conception of the national system of political economy 1841 which might just as well have been called the national system of innovation the main concern of list was with the problem of germany overtaking england and for underdeveloped countries as germany then was in relation to england he advocated not only protection of infant industries but a broad range of policies designed to accelerate or to make possible industrialisation and economic growth most of these policies were concerned with learning about new technology and applying it the racialist and colonialist overtones of the book were in strong contrast to the inter nationalist cosmopolitan approach of the classical free trade economists and list s belief that holland and denmark should join the german bund and acquire german nationality because of their descent and whole character reads somewhat strangely in the european community of today nevertheless despite these unattractive features of his outlook he clearly anticipated many contemporary theories after reviewing the changing ideas of economists about development in the years since the second world war the world bank 1991 concludes that it is intangible investment in knowledge accumulation which is decisive rather than physical capital investment as was at one time believed pages 33 35 the report cites the new growth theory

detection and impact of industrial subsidies the case of world shipbuilding this paper provides a model based empirical strategy to i detect the presence and gauge the magnitude of government subsidies and ii quantify their impact on production reallocation across countries industry prices costs and consumer surplus i construct and estimate an industry model that allows for dynamic agents in both demand and supply and apply my strategy to world shipbuilding a classic target of industrial policy i nd strong evidence consistent with china having intervened and reducing shipyard costs by 15 20 corresponding to 5 billion us dollars between 2006 and 2012 the subsidies led to substantial reallocation of ship production across the world with japan in particular losing signi cant market share they also misaligned costs and production while leading to minor surplus gains for shippers

should i stay or should i go an agent based setup for a trading and monetary union abstract the recent history of the european union eu suggests the importance of studying the conditions under which two or more countries can benefit from becoming part of a union of course this depends both on the economic characteristics of the involved countries and on the scope of the union i e the level of integration of markets regulations and institutional bodies this study tackles the topic from the angle of agent based computational economics by designing an open economy model inspired from the eu where countries can be part of a trade and monetary union we find that for similar countries it is always beneficial to be a member of a union although a lack of mobility frictions can cause a divergence between the two countries weakening the overall union performance even if countries have different productivity the performance of the union is in general better than the performance of the isolated countries the exception is when productivity gap and labor mobility are both high in this case a strong migration within the union can create economic distortions exacerbating the gap between the member states stronger fiscal integration helps reducing inequality between countries increasing the sustainability of the monetary union

efficiency gains in danish district heating is there anything to learn from benchmarking abstract facing a market structure of independent heating systems and cost of service regulation the regulator considers ways to create incentives for increasing efficiency in heat production one way is to implement benchmark regulation the aim of this paper is twofold 1 to investigate the potential for increasing productivity in danish district heating production and 2 to examine whether benchmarking has a role to play using data envelopment analysis our analyses show that by assuming variable returns to scale a potential exists to reduce production costs by 5 27 depending on the portfolio of inputs and outputs included in the model further our analyses show that the ranking of producers is much dependent on the combination of inputs and outputs included in the model therefore great care should be taken when deciding on the appropriate model to be used when implementing benchmarking as a regulatory mean

innovation and recurring shifts in industrial leadership three phases of change and persistence in the camera industry abstract this study examines factors underlying three phases of change or persistence in industrial leadership in the sector of interchangeable lens cameras over the past century during this period there were two major phases of leadership change both associated with the emergence of innovations involving major discontinuities in the industry s core technologies first japan won market leadership from germany in the mid 1960s after commercializing the single lens reflex slr camera that replaced the previously dominant german rangefinder camera second in the late 2000s japanese latecomer firms and a korean firm developed mirrorless cameras which allowed them to capture the majority of market share from the incumbent japanese leaders we also examine the long period about 60 years between these two phases of change during which leading japanese firms were able to sustain their market leadership despite the digital revolution from the 1980s to 1990s this paper explores the factors influencing these contrasting experiences of change and persistence in industry leadership the analysis integrates several aspects of sectoral innovation systems i e windows of opportunity associated with technology demand and institution as well as the strategies of incumbents and latecomer firms the conclusions highlight the complex and diverse combinations and importance of the factors that help explain the patterns of shifts in leadership

a goal programming constrained regression review of the bell system breakup the recently implemented court decision to break up bell american telephone telegraph co to accord with u s anti trust laws represents a highly significant policy decision which is proving to be influential in other countries as well as the u s the telecommunication industry is of such size and importance that even relatively small economies that might be lost with bell s breakup as a natural monopoly could involve substantial welfare losses to consumers and producers studies commissioned by the u s justice department that approached this topic by econometric methods reported that the evidence failed to support the contention that bell was a natural monopoly here a goal programming constrained regression as developed in the management science literature uses the same functional form and the same data but nevertheless reverses the main findings of the econometric studies in every one of the 20 years covered this kind of difference in results obtained by two different methods of analysis poi

schumpeter meeting keynes a policy friendly model of endogenous growth and business cycles this paper studies an agent based model that bridges keynesian theories of demandgeneration and schumpeterian theories of technology fueled economic growth we employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply demand and the fundamentals of the economy we find profound complementarities between factors influencing aggregate demand and drivers of technological change that affect both short run fluctuations and longterm growth patterns from a normative point of view simulations show a corresponding complementarity between keynesian and schumpeterian policies in sustaining long run growth paths characterized by milder fluctuations and relatively lower unemployment levels the matching or mismatching between innovative exploration of new technologies and the conditions of demand generation appear to suggest the presence of two distinct regimes of growth or absence thereof characterized by different short run fluctuations and unemployment levels

the dynamics of international differentiation a multi country evolutionary model the paper presents some admittedly preliminary results on evolutionary modeling of open economies interactions the dynamics is microfounded in a multiplicity of boundedly rational agents who imperfectly learn how to innovate in environments characterized by notionally unlimited opportunities micro discoveries is shown can generate persistent system level effects despite the absence in the model of any institutional specificity of individual countries processes of innovative exploration and imitation yield international divergence less often convergence catching up and falling bebind
