FURTHER EVIDENCE ON REAL INTEREST RATE EQUALIZATION: PANEL INFORMATION,NON‐LINEARITIES AND STRUCTURAL CHANGES

Previous studies applying traditional unit root tests generally have difficulty providing widespread evidence supporting the real interest rate parity hypothesis (RIPH). This paper aims to analyse the empirical fulfilment of RIPH for 17 OECD countries by employing many recently developed unit root tests. Power of the tests is raised by taking different approaches, such as using cross‐sectional information, accounting for non‐linear adjustment towards the equilibrium and allowing for structural changes. The combined results of the tests using panel information show that broad evidence in favour of RIPH prevails for 13 of the 17 countries. By contrast, univariate tests fail to make widespread rejections of the unit‐root hypothesis. Our evidence reveals a high degree of market integration for developed countries, and the effect of monetary policies as a stabilization tool might be limited at least in the long run.     

A model of intermarriage involving attribute exchange

The increasing pace of globalization has significantly affected our lives in many profound ways. One of the consequences of globalization is the rise of intermarriage, i.e., the marriage between couples of different nationalities or different social, economic, religious, or racial backgrounds. Since our understanding of intermarriage is limited, this paper attempts to shed lights on intermarriage by developing a formal model based on attribute exchange. After examining the motivation and micro and macro consequences of intermarriages, our model shows that different value systems regarding marital attributes among different groups drive individuals with attributes valued lower in their group to seek intermarriage. As a result, the essence of intermarriages is the movement of attributes from groups in which such attributes are relatively abundant to groups where the same attributes are relatively scarce. Thus, intermarriage makes individuals with attributes valued lower in their original groups better off. At the inter‐societal (or inter‐group) level, the equilibrium of intermarriage is determined by the relative scarcity of marital attributes in different groups (societies). In the long run, intermarriages converge different groups in terms of their value systems regarding marriage.     

Optimal investment-reinsurance with dynamic risk constraint and regime switching

We study an optimal investment–reinsurance problem for an insurer who faces dynamic risk constraint in a Markovian regime-switching environment. The goal of the insurer is to maximize the expected utility of terminal wealth. Here the dynamic risk constraint is described by the maximal conditional Value at Risk over different economic states. The rationale is to provide a prudent investment–reinsurance strategy by taking into account the worst case scenario over different economic states. Using the dynamic programming approach, we obtain an analytical solution of the problem when the insurance business is modeled by either the classical Cramer–Lundberg model or its diffusion approximation. We document some important qualitative behaviors of the optimal investment–reinsurance strategies and investigate the impacts of switching regimes and risk constraint on the optimal strategies.     

The economic burden of psoriasis with high comorbidity among privately insured patients in the United States

Objective: To evaluate the impact of comorbidities on healthcare resource use (HRU), and direct and indirect work-loss-related costs in psoriasis patients.

Methods: Adults with psoriasis (≥2 diagnoses, the first designated as the index date) and non-psoriasis controls (no psoriasis diagnoses, randomly generated index date) were identified in a US healthcare claims database of privately-insured patients (data between January 2010 and March 2017 were used). Psoriasis patients were stratified based on the number of psoriasis-related comorbidities (0, 1–2, or ≥3) developed during the 12?months post-index. All outcomes were evaluated during the follow-up period, spanning the index date until the end of continuous health plan eligibility or data cut-off. HRU and costs per-patient-per-year (PPPY) were compared in psoriasis and non-psoriasis patients with ≥12?months of follow-up.

Results: A total of 9,078 psoriasis (mean age?=?44?years, 51% female) and 48,704 non-psoriasis (mean age?=?41?years, 50% female) patients were selected. During the 12?months post-index, among psoriasis vs non-psoriasis patients, 71.0% vs 83.0% developed no psoriasis-related comorbidities, 26.3% vs 16.0% developed 1–2, and 2.6% vs 1.0% developed ≥3 psoriasis-related comorbidities. Compared to non-psoriasis patients, psoriasis patients had more HRU including outpatient visits (incidence rate ratios [IRRs]?=?1.52, 2.03, and 2.66 for 0, 1–2, and ≥3 comorbidities, respectively [all p?p?p?p?Conclusions: HRU and cost burden of psoriasis are substantial, and increase with the development of psoriasis-related comorbidities.

On the Value of Environmental Certification in the Commercial Real Estate Market

A significant part of the global carbon externality stems from the real estate sector. Environmental certification is often hailed as an effective means to resolve the information asymmetry that may prevent markets from effectively pricing the energy performance of buildings. This study analyzes the adoption and financial outcomes of environmentally certified commercial real estate over time. We document that nearly 40% of space in the 30 largest U.S. commercial real estate markets holds some kind of environmental certification in 2014, as compared to less than 5% in 2005. Tracking the rental growth of 26,212 office buildings, we measure the performance of environmentally certified real estate over time. We document that certified office buildings, on average, have slightly higher rental, occupancy and pricing levels, but do not outperform non‐certified buildings in rental growth over the 2004–2013 period. Further performance attribution analysis indicates that local climate conditions, local energy prices and the extent of certification lead to significant heterogeneity in market pricing. On aggregate, these findings provide some evidence on the efficiency of the market in the adoption and capitalization of environmental characteristics in the commercial real estate market.     

Residential energy use and conservation: Economics and demographics

Energy consumption in the residential sector offers an important opportunity for conserving resources. However, much of the current debate regarding energy efficiency in the housing market focuses on the physical and technical determinants of energy consumption, neglecting the role of the economic behavior of resident households. In this paper, we analyze the extent to which the use of gas and electricity is determined by the technical specifications of the dwelling as compared to the demographic characteristics of the residents. Our analysis is based on a sample of more than 300,000 Dutch homes and their occupants. The results indicate that residential gas consumption is determined principally by structural dwelling characteristics, such as the vintage, building type, and characteristics of the dwelling, while electricity consumption varies more directly with household composition, in particular income and family composition. Combining these results with projections on future economic and demographic trends, we find that, even absent price increases for residential energy, the aging of the population and their increasing wealth will roughly offset improvements in the energy efficiency of the building stock resulting from policy interventions and natural revitalization.     

BOOTSTRAPPING COVARIATE UNIT ROOT TESTS: AN APPLICATION TO INFLATION RATES

This paper proposes a bootstrap procedure for the covariate point optimal tests (CP_T) of Elliott and Jansson. Although the covariate tests enjoy large power gains over the traditional univariate unit root tests, our simulations show that they still suffer from severe size distortions at finite samples. Through simulations, we demonstrate the superiority of the bootstrap procedure in the sense that it can yield desirable size and power properties for the CP_T tests when the Akaike's information criterion is used. Moreover, we show the empirical relevance of the bootstrap tests by applying them to inflation in the G‐10 countries, and then obtain strong evidence against the unit root hypothesis for most countries at the 5% significance level.
