We extend the vector autoregression (VAR) based expectations hypothesis (EH) test of term structure, considered in Bekaert & Hodrick (2001), B&H thereafter, using recent developments in bootstrap literature. Modifications include the use of wild bootstrap to allow for conditional...

In practical portfolio choice models risk is often defined as VaR, expected shortfall, maximum loss, Omega function, etc. and is computed from simulated future scenarios of the portfolio value. It is well known that the minimization of these functions can not, in general, be performed with...

This paper proposes Lagrange Multiplier based panel unit root tests allowing for structural breaks through simple extensions of existing group mean and combination tests. The proposed tests are more general than those previously suggested. They consider potential breaks in the intercept, in the...

One important factor concerning economic models is that frequently large amounts of data are produced. There is the research issue of how end-users (who may not be researchers or model developers) can be presented with this data so that maximum benefits can be attained from the data production....

We deal with bootstrapping tests for detecting conditional heteroskedasticity in the context of standard and nonstandard ARCH models. We develope parametric and nonparametric bootstrap tests based both on the LM statistic and a neural statistic. The neural tests are designed to approximate an...

This paper analyses collusion by innovative firms and the role of patents in a continuous-time real options framework. A patent-investment race model is formulated in which innovative firms bargain and reach collusive agreements. It is shown that, while collusion always delays innovation, it...

Frech-Ginsburg showed that medical insurance reimbursement systems with certain price-control characteristics cause chronic price inflation. We construct a three-party market in which Experts, Non-Experts and Insurers negotiate with each other for services, insurance coverage and cash in such a...

A group of developing countries bear high rates of financial dollarisation. Under this circumstance, monetary-policy makers are uncertain about the presence and scale of potentially harmful effects that might appear because of balance sheet mismatches arising from high and unexpected...

The accuracy of the solution of dynamic general equilibrium models has become a major issue. Recent papers, substituting second order for first order approximations, have shown to obtain significant differences in accuracy. Second order approximations have had some considerable success in...

Emprical studies of hyperinflations reveal that the rational expectations hypothesis fails to hold. To address this issue, we study a model of hyperinflation and learning in an attempt to better understand the volatility in movements of expectations, money, and prices. The findings surprisingly...
