The paper analyzes how social barriers to communication affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labor, a negative relationship is shown to exist between social barriers to communication and total factor productivity (TFP), per capita consumption and reproducible cap...

It is well known that the use of different criteria for estimation and evaluation can affect the ranking of models. This paper uncovers a different problem – and inconsistency – that can arise when alternatives are compared using an estimated criterion function. Our results are relevant for empirical studies where evaluation is based on estimated criteria functions, such as utility functions of...

In this paper we investigate the relevance of considering a large number of macroeconomic indicators to forecast the complete distribution of a variable. The baseline time series model is a semi-parametric specification based on the Quantile Auto-Regressive (QAR) model that assumes that the quantiles depend on the lagged values of the variable. We then augment the time series model with macroec...
