To determine whether an industry exhibits constant returns to scale, whether the production fUnction is homothetic, or whether inputs are separabl~ a common approach is to specify a cost function, estimate its parameters using data such as prices and quantities of inputs, and then test the parametric restrictions corresponding to constant returns, a homothetic technology, or separability. Stati...

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...

background: in order to extend hbv immunization to twenty-five-year old adolescents, ministry of health and medical education (moh & me) in iran has decided to implement hbv mass vaccination campaign for adolescents who were born from 1989 to 1992. the first three-round campaign covering 1989 born adolescents was implemented in 2007 in iran. this study was conducted for cost estimation and anal...

In this paper, we formulate a behavioral model under uncertainty to estimate the total factor productivity in the Taiwan banking industry. In particular, the paper provides a model based on the safety-first rule under uncertainty to measure the risk premium in banking operations that are subject to loan default and other investment risks. Using panel data of forty banks in 1981-1996, a translog...

In this paper, I emphasise that the main prediction of the theoretical literature on the firm as an incentive structure is that different organisations (i.e. firms with different allocations of property rights) are characterised by different levels of social transaction costs, hence by different levels of economic inefficiency. I then propose a test of this prediction focusing on the banking in...

The aim of this study was to measure the potential of production and the capacity used in the pharmaceutical industry. Capacity use is the actual production rate to the potential output, which reflects the gap between actual production and production capacity. Through econometric methods, translog cost function in the short run along with functions of share cost of production factors is estimat...

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...
