Increase of electricity price and energy efficiency: analysis using the macroeconomic interindustry model of Taiwan

From 2012 to 2013, the price of electricity in Taiwan increased by 19.78%. This large increase forced producers to invest in improving electricity efficiency. In this paper, the macroeconomic interindustry model of Taiwan (MEIT) is developed to study the economic effects of high electricity prices and consequential improvement in energy efficiency. MEIT describes the structure of 47 industries, from both real and price-income approaches. To resolve inconsistent data, RAS is employed. A technical model is also integrated to consider technical feasibility, which offsets the usual shortcomings of technological analysis in an economic model. The iron and steel industry is taken as a case study. Estimated results indicate that higher electricity prices negatively affect Taiwan’s economy. However, improving energy efficiency can reduce some of this effect.     

Competing in the global aerospace supply chain: The case of the Canadian aerospace industry

In light of the vertical disintegration of the global aerospace industry, this paper reports on a study that was commissioned by Industry Canada to evaluate whether Canadian aerospace firms have been able to develop the new set of manufacturing and managerial capabilities required to compete in the global aerospace supply chain. A strategic management framework was used to assess the fit between the key success factors of the external environment and the resources and capabilities of the firms studied. The results indicate that although smaller aerospace firms seem to possess technological and engineering skills that are vital strengths in the aerospace industry, better marketing efforts would enable them to enlarge their client base and intensify their participation in the global aerospace supply chain.     

Open standards,vertical disintegration and entrepreneurial opportunities: How vertically-specialized firms entered the U.S. semiconductor industry

This paper shows how the emergence of open standards has created large numbers of entrepreneurial opportunities in the semiconductor industry by enabling vertical specialization. Integrating data on firms and technology evolution, we find a gradual increase in the percentage of firms represented by newly-founded “de novo” entrepreneurial startups, instead of “de alio” ones, as open standards emerged in semiconductor products and processes over the life of the industry. This standardization reduced transaction costs and fostered specialization, thus facilitating the entry of vertically-specialized new ventures. Vise versa, the rise of such new ventures further pushed the adoption of open standards, and the vertical disintegration of the industry. Our theory on how standardization creates opportunities for new ventures and our analysis of the semiconductor industry contribute to the technology entrepreneurship literature, as well as the industry architecture literature that has primarily focused on the impact of standardization on the disintegration of vertically-integrated incumbents.     

Environmental regulation, technological diversity, and the dynamics of technological change

Inducing technological progress is an important objective of environmental regulation. We investigate under which conditions regulation-induced technological progress pursues the best technological option. We analyze a setting with vertical and horizontal technological progress, cost uncertainty, time-limited patent protection, and a case that is typical for some emissi4on-intensive industries, like electricity generation or the chemical industry. Under taxes and standards, only the current least-cost technology is used and developed, implying a lock-in into a possibly inferior technology. Tradable permits yield slower progress but can facilitate the simultaneous development of technologies, rendering lock-ins less likely.     

The existence of a real value-added function in the Canadian manufacturing sector

Sims (1969), Gordon (1969), and Arrow (1972) have demonstrated that the capability of using real value-added to measure the output of a sector when material inputs are employed in the production process rests upon primary factor inputs being weakly separable from material inputs. In Canada, the double deflation technique is used by Statistics Canada to measure the real value-added output of an industry; this technique assumes strong separability. This paper tests both of these separability hypotheses for the Canadian manufacturing sector using data from 1950 to 1972 and a translogarithmic production function. Our tests lead us to reject both the strong and weak separability hypotheses. Furthermore, our estimates of the Allen partial elasticity of substitution of capital for labor are radically different from the results of previous Canadian studies.     

Vertical disintegration and the life-cycle of firms and industries

T0he degree of vertical integration experienced by a firm is an important managerial decision variable. It is an issue where there is a distinct lack of unanimity in studies on the economics of organizations. Moreover, studies have tended to ignore the complementary feature of vertical disintegration. This study examines the basic Stigler hypothesis that vertical disintegration is the typical development in growing industries. Using UK data on divestments, the results initially indicated some positive relationship between industry growth and vertical divestment activity; however, when different categories of asset transfer were examined, the Stigler view was rejected in favour of a null hypothesis.     

Vertical structure and the risk of rent extraction in the electricity industry

This paper studies how competition and vertical structure jointly determine generating capacities, retail prices, and welfare in the electricity industry. Analyzing a model in which demand is uncertain and retailers must commit to retail prices before they buy electricity in the wholesale market, we show that welfare is highest if competition in generation and retailing is combined with vertical separation. Vertically integrated generators choose excessively high retail prices and capacities to avoid rent extraction in the wholesale market when their retail demand exceeds their capacity. Vertical separation eliminates the risk of rent extraction and yields lower retail prices.     

Vertical Disintegration

With economies of scale, a vertically integrated firm can lower its upstream cost by supplying downstream competitors. The competitors may strategically choose not to purchase from the integrated firm, unless the latter's price for the intermediate good is sufficiently lower than those of alternative suppliers. In a simple model of dynamic scale economies through learning by doing, equilibrium vertical disintegration occurs if and only if total industry profit is higher under vertical separation than under integration. The model bridges a logical gap in George Stigler's classic theory on vertical organization, and sheds light on the widely observed phenomenon of vertical disintegration .

Experience curve models in the electricity supply industry

There has been much controversy over the use of the Experience Curve for forecasting purposes. The Experience Curve model has been criticised both on theoretical grounds and because of the practical problems of using it. An alternative model of experience effects due to Towill has certain attractions from the standpoint of theory. However, a rather deeper question is whether experience curve type models produce superior forecasts to those derived using extrapolative techniques.This paper examines these questions in the context of three time series taken from the electricity supply industry, viz: average thermal efficiency; works costs; and price of electricity. The two latter series require price deflation. Both the implied GDP consumption deflator, and a wholesale price index for fuel and electricity were used for this purpose. It is argued that because of the absence of substitutes and of the effects of competition, along with the high quality of data available on the electricity supply industry, these three series provide a favourable test of the experience curve approach to forecasting. The two experience curves performed on the whole markedly worse than the simpler extrapolative methods on the two financial series examined. For the average thermal efficiency series the Towill model and the Experience Curve model marginally outperformed the extrapolative methods.Overall, there was little support for using either the Experience Curve or Towill models. These are obviously more difficult to use than simple univariate models and do not provide significantly better forecasts. Moreover, the Towill model gave rise to considerable estimation and specification problems with the data used here.

The performance of coal-burning electric generating units in the United States: 1960–1980

This paper studies determinants of the thermal efficiency and reliability of coal-burning electric generating units using a new, comprehensive, unbalanced panel data set. For two major technological groups consistent and efficient estimates are obtained of the effects of unit age, vintage, scale, operating practices, and coal quality. Large utilities integrated into design and engineering appear to obtain superior unit performance. Implications of our results for life-cycle generation costs, regulators' performance norms, and the complex pattern of technological change in this industry are discussed.     

Geographic concentration and vertical disintegration: Evidence from China

Existing theoretical literature predicts that geographic concentration encourages vertical disintegration of firms. Nevertheless, empirical evidence of this prediction is limited, especially in developing countries. Using data on manufacturing firms from China, this paper documents a positive correlation between geographic concentration and vertical disintegration. Additionally, this paper uses the instrumental variable approach to address the issue of endogeneity and finds that geographic concentration has a positive causal effect on vertical disintegration.     

Competition under continuous technological change

This paper examines competition patterns and competitive strategies when technology changes continually. It first discusses optimal behavior for investment in technology. It is argued that although technological innovations supersede existing technologies, there are economically justifiable barriers to investing in the new technologies. These economic barriers, coupled with continuous technological change, have implications for certain aspects of strategy, such as entry by means of new technologies, timing of entry, leapfrog-type competition, vertical integration, the productivity dilemma, and escalating commitment. Finally, the industrial transformation of the steel industry is used as an example to illustrate these implications.

Vertical separation of transmission control and market efficiency in the wholesale electricity market

This study examines how vertical separation of transmission control affects the wholesale market efficiency in the electric power industry. We analyze a unique regional electricity wholesale market in the U.S. where initially restructuring only occurred in the transmission sector. Following a commonly-used best dispatch model (Wolfram, 1999; Borenstein et al., 2002), we simulate competitive benchmark prices and compare with the best estimates available for actual prices to measure price-cost markups of the wholesale market. Empirical results demonstrate that the vertical separation of transmission control led to a significant increase in market markups in peak-load hours, documenting evidence of enhanced market power. Although we also find a reduction in the price-cost margin in low-demand hours, we reserve caution for this finding.     

A transaction cost approach to a paradox in international marketing

Why do firms that make specific downstream investments as they start international operations, sometimes turn to more market-like arrangements as they gain international experience and their international sales increase? This paradox in international marketing is the key question to be addressed in this article. We use the concept of dynamic or temporary governance costs to examine the paradox. The pattern of internationalization in the Norwegian farmed salmon industry provides an example whereby Norwegian exporters established their own sales offices in several international markets in the early stages of internationalization, but subsequently disintegrated vertically and came to rely on more market-like arrangements. An analysis of the internationalization of this industry suggests that, over time, the market provided better capabilities than vertical integration. This reduced the transaction costs, thus making vertical disintegration an efficient strategy.     

Efficiency and Technological Change in the U.S. Brewing Industry

This study demonstrates that the measurement of technological change and economic efficiency are tightly linked. Efficiency measures may depend on carefully controlling for technological change, while tests of technological change may be sensitive to empirical model specifications. Moreover, the study underlines Solow's (1994) and Romer's (1994) admonition that econometricians should pay attention to industry and institutional evidence in building models of technological change. The empirical results presented here suggest that there has been substantial technological change in the U.S. brewing industry from 1950 to 1992. This occurred in the form of a dramatic shift in technology beginning with the introduction of super breweries in about 1972. There has also been a substantial increase in scale economies, which undoubtedly caused many inefficiently small firms to exit the industry during the 1960s and 1970s. Further results suggest that a more complete specification of technological change and the stochastic nature of the frontier production function leads to higher and more tenable estimates of efficiency.
