The paper deals with the computation of DSGE models with a large number (or continuum) of heterogenous agents and incomplete markets. Solving this model requires approximate aggregation, representing the cross-sectional distribution by a finite number of state variables. In the existing literature, people compute nonlinear solutions with a very low-dimensional state vector, or a high-dimensiona...

The world’s markets are increasingly interconnected, imposing additional challenges for both regulators and market participants. This paper considers the effect of inter-market dependencies on the spread of endogenously generated merger waves. Though merger activity can generate efficiency gains, it disrupts market competition and can lead to negative effects for consumers. The conditions under...

This paper provides an effi cient way to generate a set of random choices on a set of budgets which satisfy the Generalised Axiom of Revealed Preferences (GARP), that is, they are consistent with utility maximisation. The choices are drawn from an approximate uniform distribution on the admissible region on each budget which ensures consistency with GARP, based on a Markovian Monte Carlo algori...

Developing economies share both microeconomic and macroeconomic characteristics which are often unique relative to their more developed counterparts. Indeed, many authors (e.g. Parente and Prescott 2000) have emphasized the role of institutional frictions within developing nations as a major determinant of economic growth (or the lack thereof). We examine one type of institutional friction, con...

We establish a relationship between decay centrality and two widely used and computationally cheaper measures of centrality, namely degree and closeness. We show that for low values of the decay parameter the nodes with maximum decay centrality also have maximum degree, whereas for high values of the decay parameter they also maximize closeness. For intermediate values, we provide sufficient co...

Conditional expected values in Markov chains are solutions to a set of associated backward differential equations, which may be ordinary or partial depending on the number of relevant state variables. This paper investigates the validity of these differential equations by locating the points of non-smoothness of the state-wise conditional expected values, and it presents a numerical method for ...

This paper examines the relationship between the structure of the interbank lending market and systemic risk. We consider a model in which banks finance investment opportunities through household deposits and borrowing from other banks. Using simulation techniques a range of interbank markets structures are considered. It is shown that greater levels of interbank connectivity reduce the risk of...

through the advent of heterodox approaches in modern economic methodology, mccloskey's contribution on introducing rhetoric in methodology has been nominated as one of the most controversial propositions ever alleged in the literature. concerning new predominant perspectives in philosophy of language, this paper seeks to analyze the theoretical status of rhetoric in the methodology of econ...

We present a theory of interpersonal economic changes based on three simplest elements: Positive Sum Games, Zero-Sum and Games «with subtraction». This proposal integrates Menger’s Mises’s theories; it includes also the distinction made by Böhm-Bawerk between goods promises. On such ground we comprehensive explanation for boom-burst cycle processes, distinguishing where is damaging character re...
