Employment in DIY Superstores

Employment patterns in food superstores have received much research attention in recent years. Employment in non-food superstores has, however, been inadequately researched. Anecdotal and visual evidence suggests that non-food superstores employ fewer staff, more males than females, and more full-time than part-time workers, in comparison with food superstores,. This article quantifies employment in DIY superstores as a basis for future research.     

Lease Maturity and Initial Rent: Is There a Term Structure for UK Commercial Property Leases?

Seminal work by Grenadier (J. Financ. Econ. 38:297–331, 1995) derived a set of hypotheses about the pricing of different lease lengths in different market conditions. Whilst there is a compelling theoretical case for and a strong intuitive expectation of differential pricing of different lease maturities, to date the empirical evidence is inconclusive. Drawing upon a substantial database of commercial lettings in central London (West End and City of London) over the last decade, we investigate the relationship between rent and lease maturity. In particular, we test whether building quality, credit risk and micro-location variables omitted in previous studies provide empirical results that are more consistent with the theoretical and intuitive a priori expectations. It is found that initial leases rates are upward sloping with the lease term and that this relationship is constant over time.

Active intermediation in a monetary overlapping generations economy

This paper establishes that the profit-seeking activities of private intermediaries can ensure Pareto efficiency in the standard pure-exchange monetary overlapping generations economy without the need for government monetary or fiscal policy intervention. Moreover, these profit-seeking activities are shown to rule out all aperiodic and k-periodic cycles for k greater than 2. Contrary to much recent work on intermediation, the profit opportunities that arise for intermediaries in this context are not due to assumed frictions or asymmetric information. Rather, they are due to the dynamic open-ended structure of the economy, which permits debt roll-over.     

Where can obesity management policy make the largest impact? Evaluating sub-populations through a microsimulation approach

Background: There is a critical need to focus limited resources on sub-groups of patients with obesity where we expect the largest return on investment. This paper identifies patient sub-groups where an investment may result in larger positive economic and health outcomes.

Methods: The baseline population with obesity was derived from a public survey database and divided into sub-populations defined by demographics and disease status. In 2016, a validated model was used to simulate the incidence of diabetes, absenteeism, and direct medical cost in five care settings. Research findings were derived from the difference in population outcomes with and without weight loss over 15 years. Modeled weight loss scenarios included initial 5% or 12% reduction in body mass index followed by a gradual weight regain. Additional simulations were conducted to show alternative outcomes from different time courses and maintenance scenarios.

Results: Univariate analyses showed that age 45–64, pre-diabetes, female, or obesity class III are independently predictive of larger savings. After considering the correlation between these factors, multivariate analyses projected young females with obesity class I as the optimal sub-group to control obesity-related medical expenditures. In contrast, the population aged 20–35 with obesity class III will yield the best health outcomes. Also, the sub-group aged 45–54 with obesity class I will produce the biggest productivity improvement. Each additional year of weight loss maintained showed increased financial benefits.

Conclusions: This paper studied the heterogeneity between many sub-populations affected by obesity and recommended different priorities for decision-makers in economic, productivity, and health realms.     

Modelling UK house prices using cointegration: an application of the Johansen technique

This paper provides an econometric analysis of the long-term equilibrium determination of UK house prices using the relatively recent Johansen cointegration procedure. This long-term equilibrium specification is then utilized in order to estimate a parsimonious dynamic model for UK house prices.
