In this paper, we propose a panel data semiparametric varying-coefficient model in which covariates (variables affecting the coefficients) are purely categorical. This model has two features: first, fixed effects are included to allow for correlation between individual unobserved heterogeneity...

We estimate a stochastic frontier model with random inefficiency parameters, which allows us not only to identify the role of bank risk-taking on driving cost and profit inefficiency, but also to recognize heterogeneous effects of risk exposure on banks with different characteristics. We account...

Firms face a continuous process of technological and environmental changes that implies making managerial decisions in a dynamic context. However, costs and other constraints prevent firms from making instant adjustments towards optimal conditions and may cause inefficiency to be persistent in...

A two-equation integrated model is developed to capture bank profit and risk-avoidance decisions. Output is limited to customer loans. The profit function is based on output and selected inputs. Risk-avoidance (using the capitalization ratio) depends on micro and micro∗macro interactive...

This paper presents a useful theoretical and empirical modelling for a probabilistic evaluation of the bank risk states. Bank riskiness is related to a stochastic recursive profit function from which different positions arise. Provided that the bank's decision maker objective is to maximise a...

Orthogeodesic models admit marginal local cuts and therefore separate inference on subparameters is asymptotically justified. Doubly-flat orthogeodesic models admit local cuts marginally and conditionally. Two important empirical models for panel data are used to illustrate this property and...

This paper deals with a dynamic adjustment process in which adjustment of a key variable input (labor) towards its desired level is modeled in a panel data context. The partial adjustment type model is extended to incorporate firm- and time-specific adjustment parameter. A flexible (translog)...

A reduced-form equation relating the log of the capital account ratio to several micro and macro variables, particularly the profitability variable, for the commercial banks in nine European countries over eleven years, 1991-2001, was constructed. The equation consisted of a fixed-effects part...

After the collapse of the asset price bubble, Japanese banks are said to have been reluctant to write off bad loans, even in cases where there is little prospect of borrower firms being able to repay the loans extended. This phenomenon is known as forbearance lending. We illustrate this using a...
