Estimating Production Functions Using Inputs to Control for Unobservables

estimating claims reserves using ibnr reserves

شرکت های بیمه در قبال بیمه گذاران متعهد می شوند که به ازای دریافت حق بیمه، خسارت وارده به بیمه گذاران را جبران نمایند. بنابراین بیمه گر همیشه مبالغی را بر عهده دارد که متعلق به بیمه گذاران است و مربوط به تعهدات آینده می باشد. این مبالغ را ذخایر فنی یا technical reserves گویند. بیمه گر موظف است در پایان سال مالی، هنگام بستن حساب ها، ذخایر فنی را محاسبه و نگهداری کند. پس از وقوع خسارت، بیمه گذار ...

Accounting for Unobservables in Production Models: Management and Inefficiency

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...

Estimating Disaggregate Production Functions: An Application to Northern Mexico

Estimating Production Functions with Heterogeneous Firms

We present a new approach to the estimation of production functions that allows for richer patterns of firm heterogeneity than can be accommodated under the proxy variable methods of Olley and Pakes (1996) and Levinsohn and Petrin (2003). In particular, we show that the economics of the firms static input choice contains the necessary identifying information to control for the endogeneity probl...

Pedotransfer functions for estimating soil moisture content using fractal parameters in Ardabil province

Extended abstract 1- Introduction Soil moisture curve is an important characteristic of soil and its measurement is necessary for determining soil available water content for plant, evapotranspiration and irrigation planning. Direct measurements of soil moisture coefficients are time-consuming and costly. But it is possible to estimate these characteristics from readily available soil propert...
