The F1 along with parents of a 4 x 6 line x tester crosses in safflower were studied and seven parameters, i.e., D 2 7 based on 7 characters and D24 based on yield and its 3 direct componenets and mid parent value (MP-Y), F1 mean (F1-Y), relative heterosis (RH-Y), biparental average GCA (MPGCA-Y) and SCA effect (SCA-Y) for yield were estimated. Twenty four selected crosses were studied for segr...

one of the most important issues about production structure and measurement of factors utilization in industry is the study of substitutability among the production factors. while, energy, for its particular features like finite and the direct relationship between energy usage and air pollution; and specifically abundance of energy resources and allocation of subsidies to different energy carri...

In repeated games with di®erential information on one side, the labelling \general case" refers to games in which the action of the informed player is not known to the uninformed, who can only observe a signal which is the random outcome of his and his opponent's action. Here we consider the problem of minimizing regret (in the sense ̄rst formulated by Hannan [8]) when the information available...

Production function estimation on micro data suffers from persistent unobserved shocks that vary within firms and cause bias. This paper presents an estimation model where the firm chooses capital investment and productivityrelevant intangible assets in response to market conditions under partly fixed adjustment costs. Estimation on Brazilian manufacturing firm data suggests that (i) firms’ uno...

ABSTRACT An expected outcome of economic reforms in India is enhanced pace of industrialization with manufacturing sector playing a crucial role by increasing its share in output via higher investments and increased productivity. This process of industrialization was also expected to usher in possibilities for the slow growing states to catch up with the fast growing ones. This paper assesses t...

Adoption of new technology requires diversion of human and physical resources from direct production activities to learning/adjusting activities, which could reduce productivity temporarily. Focusing on the existence of such “learning cost”, we derive a simple model on the optimal timing for technology upgrading. This model suggests that, other things being equal, a firm perceived to have bette...

Using control function approaches to endogeneity, nonparametric identi…cation is established for production functions under weak conditions. The distribution of productivity is also recovered nonparametrically. Instead of "inverting out" the productivity shock, control functions "expect out" unobserved shocks. Controls are estimated using lagged levels of capital and labor as instruments, and t...
