Counting with Combined Splitting and Capture-Recapture Methods

Dupuis, Paul; Kaynar, Bahar; Ridder, Ad; Rubinstein, Reuven - Tinbergen Instituut - 2011

apply the splitting method to three well-known counting problems, namely 3-SAT, random graphs with prescribed degrees, and … binary contingency tables. We present an enhanced version of the splitting method based on the capture-recapture technique …

Time Series Models with a Common Stochastic Variance for Analysing Economic Time Series

Koopman, Siem Jan; Bos, Charles S. - Tinbergen Instituut - 2002

This discussion paper led to an article in Statistica Neerlandica (2003). Vol. 57, issue 4, pages 439-469. The linear Gaussian state space model for which the common variance istreated as a stochastic time-varying variable is considered for themodelling of economic time series. The focus of this...

Dynamic Correlation or Tail Dependence Hedging for Portfolio Selection

Elkamhia, Redouane; Stefanova, Denitsa - Tinbergen Instituut - 2011

We solve for the optimal portfolio allocation in a setting where both conditional correlation and theclustering of extreme events are considered. We demonstrate that there is a substantial welfare loss indisregarding tail dependence, even when dynamic conditional correlation has been accounted...

Long Memory Modelling of Inflation with Stochastic Variance and Structural Breaks

Bos, C.S.; Koopman, S.J.; Ooms, M. - Tinbergen Instituut - 2007

We investigate changes in the time series characteristics of postwar U.S. inflation. In a model-based analysis the conditional mean of inflation is specified by a long memory autoregressive fractionally integrated moving average process and the conditional variance is modelled by a stochastic...

How Diverse can Spatial Measures of Cultural Diversity be? Results from Monte Carlo Simulations on an Agent-Based Model

Arribas-Bel, Daniel; Nijkamp, Peter; Poot, Jacques - Tinbergen Instituut - 2014

Cultural diversity is a complex and multi-faceted concept. Commonly used quantitative measures of the spatial distribution of culturally-defined groups 'such as segregation, isolation or concentration indexes' are often only capable of identifying just one aspect of this distribution. The...

Correcting for Primary Study Misspecifications in Meta-Analysis

Koetse, Mark J.; Florax, Raymond J.G.M.; Groot, Henri … - Tinbergen Instituut - 2005

In non-experimental sciences the errors associated with model misspecifications in primarystudies carry over to meta-analysis. We use Monte Carlo simulations to analyse the effects ofthese misspecifications on results of a meta-analysis using a meta-estimator that calculates asimple average...

A Real Options Perspective on R&D Portfolio Diversification

Bekkum, Sjoerd van; Pennings, Enrico; Smit, Han - Tinbergen Instituut - 2007

This paper shows that the presence of conditional staging in R&D (Research & Development) has a critical impact on portfolio risk, and changes diversification arguments when a portfolio is constructed. When R&D projects exhibit option-like characteristics, correlation between projects plays a...

Strategies and Evolution in the Minority Game: A Multi- Round Strategy Experiment

Linde, Jona; Sonnemans, Joep; Tuinstra, Jan - Tinbergen Instituut - 2013

This discussion paper resulted in a publication in Games and Economic Behavior (2014). Volume 86, pages 77-95. Minority games are a stylized description of strategic situations with both coordination and competition. These games are widely studied using either simulations or laboratory...
