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

how do household characteristics affect appliance usage application of conditional demand analysis to japanese household data abstract although both appliance ownership and usage patterns determine residential electricity consumption it is less known how households actually use their appliances in this study we conduct conditional demand analyses to break down total household electricity consumption into a set of demand functions for electricity usage across 12 appliance categories we then examine how the socioeconomic characteristics of the households explain their appliance usage analysis of micro level data from the nation survey of family and expenditure in japan reveals that the family and income structure of households affect appliance usage specifically we find that the presence of teenagers increases both air conditioner and dishwasher use labor income and nonlabor income affect microwave usage in different ways air conditioner usage decreases as the wife s income increases and microwave usage decreases as the husband s income increases furthermore we find that households use more electricity with new personal computers than old ones this implies that the replacement of old personal computers increases electricity consumption

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

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

competitiveness indices and developing countries an economic evaluation of the global competitiveness report developing countries policy makers worry about national competitiveness and closely watch indices ranking international competitive performance this paper analyzes from a development economics perspective if competitiveness is a legitimate concern and if the leading indices deserve the attention they get it assesses the best known index the global competitiveness report of the world economic forum and finds deficiencies at several levels its definitions are too broad the approach biased and the methodology flawed many qualitative measures are vague redundant or wrong these weak theoretical and empirical foundations reduce the value of the indices for analytical or policy purposes

household electricity end use consumption results from econometric and engineering models information about total electricity consumption is available for most households however the electricity consumption related to different end uses e g space heating lighting and services from household appliances are usually not metered metering data are costly to achieve and in this paper we study two methods for end use estimation which can be applied on household data for appliance holdings demographic and economic variables the first method is the engineering model which has been used to calculate the so far only documented norwegian end use results applied on data from a norwegian energy survey the second method is an econometric conditional demand model applied on data from the same survey we compare the numerical results from the two models and give some recommendations regarding choice of end use approach and what questions to implement in household surveys designed to disaggregate electricity consumption

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

public sector organizations and agricultural catch up dilemma in emerging markets the orchestrating role of embrapa in brazil abstract how can an emerging economy beset by political economic and resource challenges jump start the technology catch up process in the agricultural sector and then forge an ecosystem to facilitate the continual generation and dissemination of innovations equally important how can it maintain the viability and salience of its catch up initiatives subsequent to the entry and inevitable dominance of multinational companies we answer these questions by studying catch up in brazil s soy seeds sector over four decades 1973 2015 in an environment of political and economic uncertainty embrapa a public sector organization forged partnerships to first develop absorptive capacity and innovation capabilities and then build an ecosystem of diverse organizations to generate and disseminate catch up outcomes to farmers and other end users embrapa also developed critical tacit knowledge and complementary assets that along with its emphasis on environmental sustainability and protecting national interests helped maintain its salience even after the entry and market dominance by multinational agribusinesses in addition to demonstrating critical roles for public sector organizations and public private networks in technological catch up in an emerging economy s agricultural sector our study calls into question the prevalent notion of technological catch up as a rush to reach the technological frontier at any cost

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

exploring the dynamics of water innovation foundations for water innovation studies the urgent need for innovation to address multifaceted and intertwined water related challenges is becoming increasingly clear acknowledged and responded to with cumulating sources and amounts of funding nevertheless the water sector has been claimed to be less innovative than other sectors this special volume on the dynamics of water innovation is based on the realization that in general there is a striking absence of academic studies on the dynamics of water innovation this sv is therefore designed to lay the foundations for the field of water innovation studies in an effort to integrate the emerging insights together the contributions in this sv capture the current understanding of the dynamics of water innovation and provide insights into how the water innovation process can be fostered the purpose of this introductory article is threefold namely to frame the discussion on water innovation dynamics in order to contextualise the contributions of this sv to provide systematic guidance for studying water innovation dynamics and to suggest the way forward for water innovation studies it captures the extent of the field of water innovation studies with a review of the literature of the last three decades and frames water innovations based on five decades of innovation research and drawing on three areas management strategy and policy we provide an innovation studies taxonomy that consists of four organising dimensions type of innovation stage of innovation level of analysis and measurement this taxonomy enables researchers to study the dynamics of water innovation from different combinations of conceptual and thematic angles drawing on the field of innovation studies in a systematic fashion finally we reflect on the way forward for water innovation studies with suggestions for future research 2017 the authors

catching up by hiring the case of huawei hiring experts in centers of state of the art technology is an important way in which a multinational enterprise mne can gain competitive advantage and yet use of this mechanism remains under researched this study uses the case of a chinese mne that recently achieved a leading position in the telecommunications market huawei technologies taking the perspective of huawei s offshore hires i find that greenfield investments contributed to overcoming liabilities of origin and outsidership in the global telecommunications industry nevertheless even now that huawei has caught up with industry incumbents its output capabilities remain dependent on the innovation capabilities of its offshore experts

replacement or additional purchase the impact of energy efficient appliances on household electricity saving under public pressures abstract this study examined the influence of additional and replacement purchases of energy efficient air conditioners on power savings we used a questionnaire survey and measured electricity use data from 339 japanese households collected from two city areas with different level of government requested electricity saving rates namely osaka 10 and matsuyama 5 the main findings of our study are as follows 1 households that purchased energy efficient air conditioners saved more electricity than those that did not 2 additional purchase households showed significant energy savings whereas replacement households did not the rebound effect may negate the energy saving effects of a new air conditioner 3 altruistic attitude is associated with more active participation in power saving 4 households in osaka saved more electricity than those in matsuyama probably because the government call to save electricity was more forceful

the made in effect and leapfrogging a model of leadership change for products with country of origin bias abstract change in industrial leadership is often explained in terms of technological and costs advantages however firms in emerging economies not only have to produce high quality cost competitive goods but also win the resistance of consumers in the world market who are often adverse to purchasing products from countries that yet have to build a reputation we argue that this country of origin bias significantly influences the chances of leadership change a model that aims at capturing the endogenous dynamics of demand building and leapfrogging is proposed we show that in sectors with high monopoly power acquiring a superior technology is not sufficient for a latecomer country to become leader unless a significant share of consumers is aware of the quality of its products an extension of the model to multiple sectors shows that a latecomer country remains specialized into low value undifferentiated goods even after overtaking the technology of the leading country

elasticities of electricity demand in urban indian households abstract in the past several electricity demand studies have been published for india based on aggregate macro data at the country or sub national state level since the underlying theory of consumer demand is based on the behaviour of individual agents the use of micro data which reflects individual and household behaviour more closely can shed greater light on the nature of consumer responses in this paper seasonal price and income elasticities of electricity demand in the residential sector of all urban areas of india are estimated for the first time using disaggregate level survey data for about 30 000 households three electricity demand functions have been econometrically estimated using monthly data for the winter monsoon and summer season in order to understand the extent to which factors like income prices household size and other household specific characteristics influence variations observed in individual households electricity demand the results show electricity demand is income and price inelastic in all three seasons and that household demographic and geographical variables are significant in determining electricity demand

residential electricity demand in spain new empirical evidence using aggregate data this paper presents an empirical analysis on residential demand for electricity this analysis has been performed using aggregate panel data at the province level for 47 spanish provinces for the period from 2000 to 2008 for this purpose we estimated a log log demand equation for electricity consumption using a dynamic partial adjustment approach this dynamic demand function has been estimated using a two step system gmm estimator proposed by blundell and bond 1998 the purpose of this empirical analysis is to highlight some of the characteristics of spanish residential electricity demand particular attention has been paid to the influence of price income and weather conditions on electricity demand the estimated short and long run own price elasticities are negative as expected but lower than 1 furthermore weather variables have a significant impact on electricity demand

knowledge diffusion market segmentation and technological catch up the case of the telecommunication industry in china abstract this paper examines the growth of technological capability in the telecommunication industry in china we apply a modified version of lee and lim s lee k lim c 2001 the technological regimes catch up and leapfrogging findings from the korean industries research policy vol 30 model of technological learning and catching up using the three cases of the shanghai bell the cit led r d consortium and indigenous companies such as huawei we analyze how the catching up in the telecommunication industry occurred we find that the important factors in the catch up are the strategy of trading market for technology the knowledge diffusion from shanghai bell both to the r d consortium and to huawei and industrial promotion by the government as a condition for successful catch up the paper points out that the technological regime of the telephone switches is featured by a more predictable technological trajectory and a lower cumulativeness these conditions and strategies helped the chinese firms to achieve a stage skipping catch up namely by skipping the stage of analogue electronic switches to jump to digital electronic switches

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

explaining divergence in catching up in pharma between india and brazil using the nsi framework since the mid twentieth century the national objective of india and brazil has been to develop industrial capabilities in essential sectors such as pharmaceuticals at the outset they shared some common features a considerable period of lax intellectual property rights regimes a large internal market and a reasonably strong cadre of scientists and engineers however over sixty years india has had much more success in building indigenous capabilities in pharmaceuticals than brazil at least to date why in exploring the answer to this question we show that in both countries the design of state policy played a crucial role and the endogenous responses in the national system of innovation consisted of two parts on the one hand most of the time the predicted and desired outcome was partially realized and on the other hand there were invariably other unpredicted responses that emerged the latter unexpected elements which were specific to the two countries pushed them along distinctive trajectories

the demand for variety a household production perspective abstract economists have devoted substantial attention to firms supply of variety but little to consumers demand for variety employing the framework of home production we trace differences in demand to differences in the opportunity costs of activities associated with investments in human capital schooling alters time costs and changes the variety of activities household members choose time budgets from australia israel and west germany show that higher own and spouses incomes raise variety suggesting positive income effects education increases variety independent of income and earnings part of its impact goes beyond a correlation of educational attainment with preferences for variety

time saving innovations time allocation and energy use evidence from canadian households abstract time and energy are major inputs into the production of household goods and services as a result the market penetration of time saving technologies for general household use is expected to affect both a household s i allocation of time across home production and leisure activities and ii energy use for example with a household s adoption of a microwave or a dishwasher cooking food and washing dishes will require less time and therefore in home meal preparation may increase households with microwaves or dishwashers may also opt to spend more time undertaking other production activities inside or outside the home or engage in more leisure watching tv reading exercising to the extent that time is reallocated from less to more energy intensive activities in the home residential energy use will increase as households adopt appliances that embody time saving technology furthermore an adoption of time saving technologies for basic household chores such as meal preparation and laundry can impact energy use due to the fact that many time saving technologies are more energy intensive than alternative technologies that require larger time commitments in this paper we use the canadian survey of household energy use data from 2003 to examine the extent to which ownership of products that embody time saving innovations affects time allocation and energy use at the household level

a technology gap interpretation of growth paths in asia and latin america abstract this paper presents a north south technology gap model which combines the schumpeterian approach to technical and structural change with the keynesian perspective on effective demand and the balance of payments bop constraint as drivers of growth three are the contributions of the paper first it develops a model in which the technology gap relative productivity and relative wages co evolve and may generate different paths of convergence or divergence between south and north depending on the parameters of the model second the parameters of the model are associated with different types of policies which allows for discussing how these policies may change the growth path finally the model is used to discuss the contrasting experiences of asia and latin america since 1970 convergence in asia and divergence in latin america have been extensively debated topics in the literature on comparative economic development which highlights the crucial role of industrial policy it is argued that the results of the technology gap model are consistent with the findings of this literature and helps understand the forces behind convergence and divergence

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

estimation of urban residential electricity demand in china using household survey data abstract this paper uses annual urban household survey data of sichuan province from 2007 to 2009 to estimate the income and price elasticities of residential electricity demand along with the effects of lifestyle related variables the empirical results show that in the urban area of sichuan province the residential electricity demand is price and income inelastic with price and income elasticities ranging from 0 35 to 0 50 and from 0 14 to 0 33 respectively such lifestyle related variables as demographic variables dwelling size and holdings of home appliances are also important determinants of residential electricity demand especially the latter these results are robust to a variety of sensitivity tests the research findings imply that urban residential electricity demand continues to increase with the growth of income the empirical results have important policy implications for the multistep electricity price which been adopted in some cities and is expected to be promoted nationwide through the installation of energy efficient home appliances

the architecture and dynamics of industrial ecosystems diversification and innovative industrial renewal in emilia romagna the paper aims at advancing our understanding of the architecture and diversification dynamics of industrial ecosystems and identifying policies for the innovative industrial renewal of mature economies industrial ecosystems are here defined as multi tiered production systems involving heterogeneous agents operating in sectoral value chains and contributing to the capability domains of the ecosystem and its participants with closely complementary but dissimilar sets of resources and capabilities the geographical boundaries of the industrial ecosystem are shaped by the evolving interdependencies linking organisations within the ecosystem and by the new linkages consolidating beyond that thus the industrial ecosystem is a structured production space centred mainly on its productive organisations as well as other institutions intermediaries and demand side actors purposefully involved in co value creation processes along various types of diversification and innovative industrial renewal trajectories drawing on a five year research programme in the emilia romagna industrial ecosystem a number of case studies are introduced to highlight these trajectories and the underpinning structural learning dynamics the paper concludes by identifying a number of policy implications focusing on strategies for enhancing the structural readiness of the industrial ecosystem and promoting smart diversification and innovative industrial renewal policies jel classifications d20 o25 o30

sectoral systems of innovation and production the concept sectoral system of innovation and production provides a multidimensional integrated and dynamic view of sectors it is proposed that a sectoral system is a set of products and the set of agents carrying out market and non market interactions for the creation production and sale of those products a sectoral systems has a specific knowledge base technologies inputs and demand agents are individuals and organizations at various levels of aggregation they interact through processes of communication exchange co operation competition and command and these interactions are shaped by institutions a sectoral system undergoes change and transformation through the co evolution of its various elements 2002 elsevier science b v all rights reserved

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

energy use and appliance ownership in ireland abstract this paper examines household energy use and appliance ownership in ireland logit regression analyses on a large micro dataset reveal how household characteristics can help explain the ownership of energy using appliances using ols regression models we explore the factors affecting residential energy demand conditional on appliance ownership results suggest that the methods of space and water heating employed by a household are even more important than electrical appliances in explaining domestic energy usage however the stock of appliances must be included in such models so that results will not be biased the methods employed in this paper can be easily adopted for studies of household energy use in other countries where household expenditure survey data are available

residential electricity consumption in portugal findings from top down and bottom up models an econometric study of the portuguese residential electricity consumption is presented with a focus on the influence of dwelling characteristics on consumption the relationship between the dwelling and household characteristics on per capita residential electricity consumption is estimated at two different scales involving two distinct databases the first includes data at the municipality level for 2001 the second is the most recent portuguese consumer expenditure survey that was collected in 2005 and 2006 the results of the analysis at both scales are consistent and indicate that household and dwelling characteristics have a significant influence on residential electricity consumption our results show that in portugal the direct effect of income on electricity consumption is low and becomes smaller when more relevant control variables are included in the analysis future demand of electricity in portugal will be significantly influenced by trends in socioeconomic factors as well as changes in the building stock these trends should be taken in consideration in the formulation of policy measures to reduce electricity consumption

the effect of the financial sector on the evolution of oil prices analysis of the contribution of the futures market to the price discovery process in the wti spot market abstract the aim of this article is to empirically measure the contribution of the futures market to the price discovery process in the spot market for benchmark crude oils specifically that for west texas intermediate wti for this purpose we test the hypothesis that the recent evolution of the financial markets has affected the future oil market so as to increase its contribution to the price discovery process of the spot market we modeled the relation between wti spot and future prices as a cointegration relation by using the kalman filter technique it was possible to obtain a time varying measure of the contribution of future markets to the price discovery mechanism the results show that in the case of wti the contribution of the futures market has been increasing especially between 2003 and 2008 and then again after the start of 2009 evidencing the growing importance of factors particular to the financial markets in determining oil prices in recent years during 2009 the spot prices adjusted to agents future expectations rather than to the current supply and demand conditions

learning and catching up in different sectoral systems evidence from six industries this article claims that catching up is a learning process that requires a long time and often differs significantly across economic sectors in the factors leading to success or failure we support these claims by examining the major factors affecting catching up by several countries in six industries india and brazil for pharmaceuticals korea china and brazil for autos india ireland israel china brazil and other countries for software korea and india for telecommunication equipment korea taiwan china and malaysia for semiconductors and china brazil costa rica and nigeria for some agricultural crops the article uses the framework of sectoral systems and argues that there are significant differences across these sectors in the variables and mechanisms involved in catching up the article identifies the common factors affecting catching up and the main differences across sectoral systems it then discusses the interplay between national systems and sectoral systems copyright 2011 the author 2011 published by oxford university press on behalf of associazione icc all rights reserved oxford university press
