In the U.S. over the past 17 years competition among banks to provide home mortgages has failed. The reason is that there is a finite need for new housing starts at around 1.8 million homes per year and that there is a finite need for funds if house prices are to move in line with the CPI...

A new monetary theory is set out to resolve the “Uncovered Interest Parity Puzzle (UIP Puzzle)”. It explores the possibility that liquidity properties of money and nominal bonds can account for the puzzle. A key concept in our model is that nominal bonds carry liquidity premium due to their...

Economic growth and unemployment exhibit an ambiguous relationship – according to empirical studies. This ambiguity can be investigated by observing the role of the underground economy in shaping the productivity of firms. Indeed, unemployment may be absorbed by underground firms, which adopt...

The cost of duration moral hazard in workplace accident insurance has been amply explored by North-American scholars in both the USA and Canada. Given the current context of financial constraints in public accounts and particularly in the Social Security system, we feel that the issue merits...

An alternative to using normally distributed random effects in modeling clustered binary and ordered responses is based on using a finite-mixture. This approach gives rise to a flexible class of generalized linear mixed models for item responses, multilevel data, and longitudinal data. A test of...

We present a new model for cost sharing in minimum cost spanning tree problems, so that the planner can identify the agents that merge. Under this new framework, and as opposed to the traditional model, there exist rules that satisfy merge-proofness. Besides, by strengthening this property and...

This paper compares the forecasting performance of three structural econometric models, namely the non-parametric, ARIMAX and the Kalman filter models, in predicting stock returns in an emerging market economy using South Africa as case study. The proposed models have different functional forms....

In this paper, we apply the narrative approach, studying the PBC's historical records, to infer policy-makers' intentions and thereby build a time series of monetary policy indicator. We show that our narrative policy indicator is informative about economic activity. Changes in it reflect the...

We propose a route choice model that relaxes the independence from irrelevant alternatives property of the logit model by allowing scale parameters to be link specific. Similar to the the recursive logit (RL) model proposed by Fosgerau et al. (2013), the choice of path is modelled as a sequence...

This paper provides a new proof of the Pythagoras Theorem on right-angled triangles via two new lemmas pertaining to, respectively, isosceles triangles and right-angled triangles, which are of pedagogical value in themselves.
