Do we really care about Biodiversity?

This paper addresses from an economic perspective the issue of global biodiversity conservation. It challenges the perception that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock of natural capital. Despite the existence of a plethora of international agreements there still seems to be a global ‘deficit of care’ surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation. More light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for biodiversity conservation. However, actual expenditures are much lower than willingness to pay estimates recorded in the published literature. Using the criteria that the ‘right’ amount of conservation effort is one where the marginal economic benefits from conservation just equal the marginal costs of conservation, the paper explores the biodiversity conservation conundrum and concluded that, on the available evidence, the world does not care too much about this natural capital stock and bequests to future generations.

A two-stage translog marginal cost pricing approach for Floridian hospital outputs

Since the passage of the Affordable Care Act (ACA) of 2010, issues still remain regarding the mandated purchase of insurance to ensure more universal coverage. One such issue is the pricing of these insurance packages and whether or not the reimbursements will cover necessary services. Therefore, policy concerns exist that increasing the number of insured individuals may not curtail costs. Conversely, providers may not wish to treat patients covered by excessively frugal plans such as Medicaid; hence the trade-offs between access and cost control. In this article, we present findings from a cost function and a productivity approach to determine the marginal cost of providing inpatient hospital care for hospitals operating in Florida during 2005. Using these methodological approaches, we are able to use the marginal rate of transformation to determine the relative marginal costs while controlling for hospital technical and allocative inefficiency. Our work differs from earlier articles as we avoid the Greene problem for cross-sectional models through a two-step approach. By including both reimbursement rates under conditions of hospital efficiency, we can ascertain payment schemes that should, at least in theory, cover necessary costs for patient care without leading to excessive input usage.     

A real-world analysis of healthcare costs and relative risk of hyperprolactinemia associated with antipsychotic treatments in the United States

Abstract

Aims: Antipsychotic medications are associated with an increased risk of hyperprolactinemia, but differ in their propensity to cause this complication. This study aimed to assess the economic burden of hyperprolactinemia, and to compare its risk among adult patients using atypical antipsychotics (AAs) with a mechanism of action associated with no/low vs high/moderate prolactin elevation.

Methods: This retrospective cohort study was based on US Commercial and Medicaid claims databases. Healthcare costs were compared between matched hyperprolactinemia and hyperprolactinemia-free cohorts using a two-part model. Risk of hyperprolactinemia was compared between patients receiving AAs with a mechanism of action associated with no/low (no/low prolactin elevation cohort) vs high/moderate prolactin elevation (high/moderate prolactin cohort) using logistic regression.

Results: In the commercially insured sample, compared to the hyperprolactinemia-free cohort (n?=?499), the hyperprolactinemia cohort (n?=?499) was associated with incremental total healthcare costs of $5,732 ($20,081 vs $14,349; p?=?.004), and incremental medical costs of $3,861 ($13,218 vs $9,357; p?=?.040), mainly driven by hyperprolactinemia-related costs. In the Medicaid-insured sample, compared to the hyperprolactinemia-free cohort, the hyperprolactinemia cohort was associated with incremental total healthcare costs of $10,773 ($30,763 vs $19,990; p?=?.004), and incremental medical costs of $9,246 ($20,859 vs $11,613; p?=?.004), mainly driven by hyperprolactinemia-related and mental health-related costs. The odds of hyperprolactinemia in the no/low prolactin elevation cohort were 4–5-times lower than that in the high/moderate prolactin elevation cohort (odds ratio =0.21; p?<?.001).

Limitations: Hyperprolactinemia may be under-reported in claims data.

Conclusions: Hyperprolactinemia is associated with substantial healthcare costs. AAs associated with no/low prolactin elevation reduce the risk of hyperprolactinemia by 4–5-times compared to AAs associated with moderate/high prolactin elevation. Treatment options with minimal impact on prolactin levels may contribute to reducing hyperprolactinemia burden in AA-treated patients.     

Did APEC's Trade Facilitation Action Plans deliver the goods?

This paper uses new data to examine whether APEC achieved its aim of reducing trade transaction costs by 10% over the 2002–2010 period. An inversion of the familiar gravity model makes it possible to infer trade costs based on the observed pattern of trade and production across economies. Analysis of trade costs calculated in this way shows that although intra- and extra-APEC trade costs fell during the sample period, they did not do so substantially more quickly than elsewhere in the world. Indeed, the region taken as a whole did not meet the 10% reduction goal. However, a considerable number of individual economies not only met the goal, they greatly exceeded it. Consistent with their outward oriented development strategies and leverage of global and regional value chains, some APEC economies saw very rapid falls in their trade costs over the 2002–2010 period, Viet Nam being a standout performer. Overall, about one third of the forum's membership for which consistent data are available met or exceeded the 10% reduction goal. APEC's two Trade Facilitation Action Plans can therefore be seen as having had mixed records of success.

Globalization,employment relations and human resources indicators in ten developed market economies: international data sets

This paper provides statistical information on internationalization, human resources and labour market outcomes in ten important developed market economies (DMEs). Such data are useful for practitioners and academics who are interested in international HRM. The article's aim is to provide easily accessible statistical tables of selected characteristics, which can be used to draw initial comparisons between countries and to test competing accounts of the impact of globalization on national patterns of employment relations. It includes standard sources so readers can elaborate and update these data.     

Health care and retirement costs in North America spiralling uncontrollably: what are employers to do?

This article addresses some of the issues related to the rising costs of employee benefits in the United States and Canada in terms of the cost of retirement pensions and employer-provided health insurance for employees and retirees. We examine various factors that affect the cost of these services for organizations as well as how these might affect the choices employers might be forced to make. We elaborate on how various factors might compel employers to shift the cost of benefits to employees. Specifically, we elaborate on various legislative, economic, and demographic constraints on these employee benefits and examine in detail two employer practices of concern, namely cash balance retirement plans and consumer-directed healthcare plans.

Wall of cash: The investment-cash flow sensitivity when capital becomes abundant

In the mid 2000s the oil and gas industry was hit by what might be best described as a ‘wall of cash’ as oil prices successively reached new record levels and access to external financing improved greatly. In this article we investigate what this sudden abundance of liquidity implied for the investment-cash flow relationship, the interpretation of which continues to generate controversy in the literature. For financially constrained firms we find that the investment-cash flow sensitivity decreases in the abundance period (2005–2008), suggesting that the financing constraints became less binding in this period. For financially unconstrained firms the investment-cash flow sensitivity instead increases over time, suggesting that this relationship is driven by agency problems related to free cash flow. Our paper is the first in the investment-cash flow literature to bring evidence from a natural experiment in which there was an unexpected, exogenous, substantial, and persistent decrease in the cost of external financing.
