This paper explores the role of unobserved managerial ability in production and its relationship with technical efficiency. Previous analyses of managerial ability have been based on strong assumptions about its role in production or on the use of proxies. We avoid these limitations by introducing managerial ability as an unobserved random variable in a translog production function. The resulti...

This paper develops a separable functional form in which all the relevant aggregator functions are modeled to the desired degree of approximation. This leads to separable structures that are more flexible than those implied by parametric restrictions of flexible functional forms. Tests of separability can then be accomplished in a non-nested framework. This approach is illustrated with an appli...

This paper introduces a publicly available database of recorded translation sessions for Translation Process Research (TPR). User activity data (UAD) of translators behavior was collected over the past 5 years in several translation studies with Translog 1 , a data acquisition software which logs keystrokes and gaze data during text reception and production. The database compiles this data into...

Domestic innovations and technology imports play important roles in boosting relative demand for skilled labor force. These factors are in turn influenced by domestic R&D investments and international trade. Using a translog cost function, this paper studies the effect of technology imports and other factors including output level and physical capital stock on the shares of skilled labor force ...

The airline industry has undergone significant changes following deregulation more than a decade ago. A prominent development in recent years has been the proliferation of airline alliances. An important question arises: are alliances cost savings or competition reducing? This paper addresses the first part of the question. However, the answer has bearing on the second part as well, since resul...

Historical estimates of productivity growth in India's iron and steel sector vary from indicating an improvement to a decline in the sector's productivity. The variance may be traced to the time period of study, source of data for analysis, and type of indices and econometric specifications used for reporting productivity growth. We derive both growth accounting and econometric estimates of pro...
