The authors report two cases of retinoblastoma with extension along the optic nerve sheath with negative surgical margins, a pattern not considered in current classifications but suggesting a high risk of metastasis. Both patients were treated with adjuvant chemotherapy alone and remain free of extraocular disease 15 and 22 months later. [J Pediatr Ophthalmol Strabismus. 2016;53:e51-e53.].

This paper provides a general procedure to estimate structural VARs. The algorithm can be used in constant or time varying coe¢ cient models, and in the latter case, the law of motion of the coe¢ cients can be linear or non-linear. It can deal in a uni…ed way with just-identi…ed (recursive or non-recursive) or overidenti…ed systems where identi…cation restrictions are of linear or of nonlinear ...

The paper studies the bank’s lending decision, based on three observed phenomena: Banks earn substantial profits from off-balance sheet activities and services, which they take into account in their lending decisions. Secondly, the critical point in the customer relation is the loan decision: the probability of the customer staying with the bank is a function of the loan extended each time one ...

This paper analyzes the linkages between credit supply conditions and bank lending. Building on the recent work of Gilchrist and Zakraǰsek [2011], we use the excess bond premium—a component of corporate credit spreads designed to measure shifts in the risk attitudes of financial intermediaries—to empirically identify credit supply shocks. Our results indicate that shocks to the excess bond prem...

This paper contributes to the analysis of the money supply process in Germany during the period of monetary targeting by the Bundesbank from 1975-1998. While the standard money multiplier approach assumes that the money stock is determined by the money multiplier and the monetary base it is argued here that both the money stock and the monetary base are determined endogenously by the optimizing...

The purpose of the study is to empirically test the presence of a bank lending channel in the Turkish economy. The empirical investigations are focused on the bank lending behaviour of 58 deposit money banks in the Turkish banking system over the period 19881999. The estimation methodology of the empirical analysis differs from that of similar studies in the literature, providing econometricall...

The recent financial crises pointed out the central role of public and private debt in modern economies. However, even if debt is a recurring topic in discussions about the current economic situation, economic modelling does not take into account debt as one of the crucial determinants of economic dynamics. Our contribution, in this paper, is to investigate the issues of borrowing and debt load...
