A general theoretical and empirical framework is developed for assessing the potential of a vertically integrated firm to foreclose downstream competitors. Using this framework a policymaker may also evaluate the empirical welfare effects from a vertically integrated firm raising rivals' costs....

This paper compares the ability of the log periodic power law (LPPL) procedure and the supremum augmented Dickey Fuller (supremum ADF) tests to confirm or reject the presence of bubbles in various time series simulations. We develop a time stamping method for the LPPL procedure and derive a more...

We present a strategy to forecast and assess customer behavior in the field of e-commerce. Starting point is the assignment of all actors in a market to an exhaustive set of potentially accessible users. Usually, only a small part of this set belongs to real customers in the context of...

Financial analysts assume that the reliability of predictions derived from regression analysis improves with sample size. This is generally true because larger samples tend to produce less noisy results than smaller samples. But this is not always the case. Some observations are more relevant...

A time-series basis decomposition and trend extraction technique known as Empirical Mode Decomposition (EMD), designed for multi-scale time-frequency decomposition in non-stationary time-series settings, will be combined with Regularised Covariance Regression (RCR) methods to produce a framework...

I estimate a theoretically and statistically satisfying model to account for the demand for lease renewals for one of the largest Real Estate Investment Trust companies (REIT) in the U.S. The variables that together account for ninety eight percent of the variation in the demand for lease...

This paper presents a game theoretic model of property tax assessment that allows a tax appraiser to either choose a high or a low assessment. The owner either accepts or challenges this assessment. A 'fixed effects' regression model is used to evaluate the differences in the assessed values of...

The cyclicality and volatility of property prices have been extensively documented. Many explanations have been proposed. This paper builds a simple dynamic general equilibrium model in which these often cited channels are assumed away. Instead, the role of intertemporal elasticity of...

This book describes the estimation and use of Klein Model I, including the formation of the individual equations, the data used for its estimation and the methodology of the construction and use of the model involving the MODLER software and an electronic computer

In this paper we present compelling evidence from a detailed analysis of historical prepayment data to demonstrate that a mortgage cohort remembers the level of the previous mortgage rate troughs experienced by the cohort. This is a general property, observed ubiquitously, that inescapably leads...
