The Cochrane-Orcutt procedure numerical examples of multiple admissible minima

We present two numerical examples of multiple admissible minima obtained by using the Cochrane-Orcutt iterative technique: a forgotten and somewhat farfetched example, constructed by Hildreth and Lu, and a new example, based on more typical economic data.     

The returns to education and wage penalty from overeducation: New evidence from Vietnam

This study intends to estimate the rate of returns to education in Vietnam, the distributive effects of education on wages, and the wage penalty from the incidence of overeducation in the Vietnamese labor market during 2004–2016. This study employs a pseudo-panel approach to address omitted variables bias and the unconditional quantile regression to identify the heterogeneity of returns to education across the income distribution. Our main finding indicates that the estimated rate of returns to education in Vietnam is approximately 6.5%, showing a downward bias from previous estimates. The returns vary across wage distributions, where a lower rate of return is observed in lower quantiles and a higher rate among those individuals at the higher quantiles. The returns to education have declined since 2008, confirming the oversupply of highly educated workers in the Vietnamese labor market with an estimated wage penalty of 17%. Government assistance measures are needed to reduce the overeducation and the wage penalty issues in the Vietnamese labor market.     

The quality of consumption: Some Australian evidence

The paper reports new estimates of Theil's index of the quality of consumption for four age groups and at two levels of affluence (income) for Australian households over the period 1975.IV to 1982.IV with special emphasis on the role played by energy and non-energy commodity groups. The evidence reveals an improvement in the quality of consumption of energy and energy-related goods and a quality deterioration in food, clothing and rent at all income levels and for all four age groups.     

Efficiency,technological change and output growth in Greek olive growing farms: a Box-Cox approach

This paper captures the relative contributions of input growth, technological change and technical efficiency to olive oil production growth for a panel data set of 125 Greek olive-growing farms for the period 1987 to 1993. A flexible generalized quadratic Box-Cox functional form is proposed to represent the underlying production technology. This functional specification copes with the problem of zero inputs and nests all widely used production frontiers. Empirical results show that the observed production growth is mainly due to increased input use since it was not accompanied by rapid introduction of technological innovations and improvements in efficiency levels.     

Flexible Adjustment in the Age of Financialisation: The Case of Norway

Norway's “Government Pension Fund” – Global (GPF-G) is large (around $400b), portfolio oriented and transparent. It tries to be ethical and has been mooted as a role model for other SWFs. The way the GPF-G is set up undergirds the US vision of a financialised world economy and it even indirectly supports US warfare in Iraq by buying treasury bills. It is also a leader in ethical investments – more than 20 private funds piggyback any divestment decision the GPF-G makes. Understanding the international implications of the GPF-G does not, however, amount to an explanation of why this vehicle was created. This article puts forward the argument that if we want to understand why and how these diverse behaviours cohere into a larger strategic whole, the fund must be interpreted as the continuation and technocratisation of a long established corporatist tradition of foreign economic policy that Peter Katzenstein more than 25 years ago labelled a strategy of flexible adjustment and domestic compensation.     

Predicting technical effciency in stochastic production frontier models in the presence of misspecification: a Monte-Carlo analysis

This paper provides a theoretical explanation for the sensitivity of technical efficiency measures to the choice of functional specification in stochastic production frontier models. It is shown that inappropriate functional specifications translate into a misspecification in the conditional mean of the stochastic frontier regression model. This misspecification, in turn, results in estimates of technical efficiency, confidence intervals and production elasticities being biased, even asymptotically. Monte-Carlo simulations reveal that the severity of the bias depends on the functional specification and the percentage contribution of the variance of technical inefficiency to the total variance of the composed errors.     

Testing for structural change in the dynamic adjustment model with autoregressive errors

The dynamic CUSUM test for structural change proposed by Kr?mer, Ploberger and Alt (1988) is investigated when the errors are serially correlated in a linear dynamic model. We show that the dynamic CUSUM test can be modified to allow for serial correlation in the disturbance using the same procedure as in Kao and Ross (1995), and that the modified dynamic CUSUM test retains its asymptotic significance levels. Monte Carlo results suggest that the empirical size of the dynamic CUSUM test is highly distorted while the empirical size of the modified dynamic CUSUM test is fairly robust to the change on the degree of autocorrelation. We also find that the power of the modified test essentially depends on the angle between the mean regressors and the structural shift.

Decentralized trade with bargaining and voluntary matching

Rubinstein and Wolinsky (1990) study a market with one seller, two buyers, and voluntary matching. Both the competitive outcomep _c and the bilateral bargaining outcomep _b are possible in subgame perfect equilibrium. We consider two variations. First, if there is a cost larger thanp _c −p _c to the seller of changing partner,p _c is the unique outcome, otherwise no restriction expires. In the second variation the seller makes anε-binding preannouncement of whether he will change buyer after disagreement. Ifε is small there are equilibrium prices close top _c . But for anyε, if the discount factor is close to 1, the unique equilibrium price isp _c . The authors thank an anonymous referee for helpful comments.
