Model error (or ambiguity) and its estimation, with particular application to loss reserving

Taylor, Greg; Mc Guire, Gráinne - In: Risks : open access journal 11 (2023) 11, pp. 1-28

two of these components, and their estimation, are well understood, but less so model error. Model error itself is … considered in two parts: one part that is capable of estimation from past data (internal model error), and another part that is … not (external model error). Attention is focused here on internal model error. Estimation of this error component is …

Escape from model-land

Thompson, Erica L.; Smith, Leonard A. - 2019

Both mathematical modelling and simulation methods in general have contributed greatly to understanding, insight and forecasting in many fields including macroeconomics. Never-theless, we must remain careful to distinguish model-land and model-land quantities from the real world. Decisions taken...

Interaction between Macroeconomics Variables and IBOVESPA, Brazilian Stock Market Index

Santos, Allan Silveira dos; Neto, Angelo Rondina; … - In: Transnational Corporations Review 5 (2013) 4, pp. 81-95

This paper analyzes the relations between macroeconomic variables and the Brazilian stock market index, the Ibovespa, from January of 2001 to December of 2011, using a Vector Error Correction model (VEC). The main results showed that the Ibovespa reacts negatively to impulses in the exchange...
