We argue that Islamic principles, in particular the avoidance of ribā and gharar should be applied with respect to real economic value rather than to monetary value in terms of conventional currency. In order to reconcile monetary value with economic value, we propose a reference currency...

There is a growing literature of theoretical models and empirical advances that has led most researchers to subscribe to the view that national macroeconomic indicators are the crucial determinants of equilibrium interest rates. This paper revisits the causal structure linking the G7 long-term...

The goal of the present paper is to investigate not only the dynamics of the Greek public debt, but also the appropriate measures required for achieving fiscal consolidation. The empirical estimation is carried out using a macroeconomic dataset spanning the period 1980-2008 and both the 3SLS...

The paper introduces a new Frequentist model averaging estimation procedure, based on a stacked OLS estimator across models, implementable on cross-sectional, panel, as well as time series data. The proposed estimator shows the same optimal properties of the OLS estimator under the usual set of...

This paper analyzes the mortgage borrowing process from a Russian state-owned supplier of residential housing mortgages concentrating on the estimation of demand function with heterogeneous borrowers' preferences. Analysis takes into account the underwriting process and the choice of contract...

We consider median regression and, more generally, quantile regression in high-dimensional sparse models. In these models the overall number of regressors p is very large, possibly larger than the sample size n, but only s of these regressors have non-zero impact on the conditional quantile of...

We analyze market order arrivals on the intraday market for hourly electricity deliveries in Germany. As we distinguish between buys and sells, we work in a multivariate setting. We model the arrivals with a Hawkes process with exponentially increasing baseline intensity and exponentially...

In this paper we develop a structural equation model with latent variables in an ordinal setting which allows us to test broker-dealer predictive ability of financial market movements. We use a multivariate logit model in a latent factor framework, develop a tractable estimator based on a...

The diversification benefit provided by real estate investment trusts (REITs) is of great importance to investors, practitioners and academics. This benefit critically relies on the correlation properties between REIT returns and the factors used to explain REIT returns. Recent studies have...
