The meta-technology cost ratio: An indicator for judging the cost performance of CO2 reduction

This paper constructs an innovative ratio of meta-technology cost (MTCR) by combining the meta-frontier framework and shadow price model. This ratio is not only an indicator to account for country-specific technology heterogeneity or technology heterogeneity across a group of countries to measure improvement toward the meta-frontier. This ratio also computes the absolute value difference between the real and ideal minimum marginal abatement costs for the non-market good CO2 to achieve specific emission reduction. An equally weighted combination of technological readiness and innovation is used to classify countries into groups. The value of the MTCR via the computation of the meta marginal abatement cost (MACmeta) and group marginal abatement cost (MACgroup-k) allows us to identify the possible improvement of marginal abatement cost (MAC) in absolute value. That is, observation of the MTCR, along with its components the MACmeta and MACgroup-k, provides more intuitive and comprehensive information for commanding the cost performance of CO2 reduction than the traditional meta-technology ratio alone.

Outward foreign direct investment and technical efficiency: Evidence from Taiwan's manufacturing firms

This paper uses firm-level panel data from Taiwan's manufacturing industries from 1987 to 2000 to investigate the impact of outward foreign direct investment (OFDI) on the technical efficiency of the OFDI firms. Propensity score matching is used to construct an appropriate group of non-OFDI firms to compare with OFDI firms, and a metafrontier framework is subsequently used to calculate comparable technical efficiencies for both groups of firms. Our empirical results reveal that the technical efficiencies of Taiwan's manufacturing firms were increasing over the entire sample period. In addition, our results suggest that the technological advances and the technical efficiency of Taiwan's manufacturing firms are positively correlated with their OFDI activity.

An examination of the cost efficiency of banks in Taiwan and China using the metafrontier cost function

Using the stochastic metafrontier framework of Battese et al. (J Prod Anal 21:91–103, 2004), this study proposes to compare and measure the cost efficiency and cost frontier gap between the banking industry in Taiwan and China. It further identifies environmental variables that determine bank’s cost frontier gap between two countries. Data on 69 sample banks for years 2005–2009 are used in the empirical analysis and inference. The empirical results show that Taiwanese banks have in general the superior cost frontier of production, but inferior cost efficiency of operation than Chinese banks. Private banks in Taiwan have the best cost frontier, whereas foreign banks in China are most cost efficient among all banks in Taiwan and China. The empirical results also reveal that the majority of Taiwanese banks are undersized and that most banks in China are oversized. Finally, the regression results show that the financial market structure, institutional environment, and political development are significant determinants of the cost gap between the cost frontiers of banks in Taiwan and China. Therefore, programs related to changes directed toward a better bank production environment can be initiated to improve the cost technologies of banks in both Taiwan and China.

Technology gaps in European banking: Put the blame on inputs or outputs?

This paper investigates the production efficiency of 12 European banking systems over the period 1997–2004, taking into account possible technology heterogeneity. Using a non-parametric metafrontier framework, efficiency and metatechnology ratio measures are computed and decomposed into input- and output-invariant components. Empirical findings indicate the existence of significant and rather increasing technology heterogeneity within European banking. A typology of the national banking systems is also developed, based on the overall productive performance with respect to the European technological edge, the absorptive capacity and the role of knowledge spillover effects. Decomposition results draw attention to catching up policies focusing on input and/or output scale adjustments.

Measuring the efficiency of highway maintenance contracting strategies: A bootstrapped non-parametric meta-frontier approach

Highly deteriorated US road infrastructure, major budgetary restrictions and the significant growth in traffic have led to an emerging need for improving performance of highway maintenance practices. Privatizing some portions of road maintenance operations by state Departments of Transportation (DOTs) under the auspices of performance-based contracts has been one of the innovative initiatives in response to such a need. This paper adapts the non-parametric meta-frontier framework to the two-stage bootstrapping technique to develop an analytical approach for evaluating the relative efficiency of two highway maintenance contracting strategies. The first strategy pertains to the 180 miles of Virginia’s Interstate highways maintained by Virginia DOT using traditional maintenance practices. The second strategy pertains to the 250 miles of Virginia’s Interstate highways maintained via a Public Private Partnership using a performance-based maintenance approach. The meta-frontier approach accounts for the heterogeneity that exists among different types of highway maintenance contracts due to different limitations and regulations. The two-stage bootstrapping technique accounts for the large set of uncontrollable factors that affect the highway deterioration processes. The preliminary findings, based on the historical data for the state of Virginia, suggest that road authorities (counties) that have used traditional contracting for transforming the maintenance expenditures into the improvement of the road conditions seem to be more efficient than road authorities that have used the performance-based contracting. This paper recommends that road authorities use hybrid contracting approaches that include best practices of both traditional and performance-based highway maintenance contracting.
