In dynamic optimization problems with multiple continuous state variables and multiple continuous controls, the method of endogenous gridpoints (ENDG) generates an irregular collection of gridpoints for which standard interpolation techniques do not apply, while alternative interpolation methods are extremely slow. This paper presents an interpolation technique that allows ENDG to be used in mu...

This paper builds upon a view of economic organizations as problem-solving arrangements and presents a simple model of adaptive problem-solving driven by trial-and-error learning and collective selection. Institutional structures and, in particular, their degree of decentralization, determine which solutions are tried out and undergo selection. It is shown that if the design problem at hand is ...

The study of asset price characteristics of stochastic growth models such as the riskfree interest rate, equity premium and the Sharpe ratio has been limited by the lack of global and accurate methods to solve dynamic optimization models. In this paper a stochastic version of a dynamic programming method with adaptive grid scheme is applied to compute the above mentioned asset price characteris...

In this paper, we propose a multivariate quantile regression method which enables localized analysis on conditional quantiles and global comovement analysis on conditional ranges for high-dimensional data. The proposed method, hereafter referred to as FActorisable Sparse Tail Event Curves, or FASTEC for short, exploits the potential factor structure of multivariate conditional quantiles through...

The title compound, [Ni(N(3))(2)(C(6)H(6)N(2)O)(2)], was obtained as the first crystalline product from the reaction of Ni(NO(3))(2)·6H(2)O, picolinamide and NaN(3) in aqueous media. After a few days in the mother liquor, crystals of the cis isomer transformed into the trans isomer [Đaković & Popović (2007 ▶). Acta Cryst. C63, m507-m509]. The Ni atom exhibits a distorted octa-hedral environment...

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...

We examine the Cournot oligopoly model in the context of social and individual learning. In both models of learning, firms update their decisions about how much to produce via variants of the genetic algorithm updating procedure. Arifovic (1994) found that both models of social and individual learning converged to the Walrasian, competitive equilibrium. Vriend (2000) reports that the model of s...

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...
