Factors contributing to business actions in response to climate change in Korea

Climate change is a growing problem and has been highlighted as a global issue. Empirical evidence increasingly indicates its obvious potential risks to humans and society. As members of this society, business organizations face greatly diverse climate change-related risks that they must recognize and respond to. However, gaps exist between scientific evidence and the actions of business organizations. Few empirical studies have examined the business organizations’ actions taken in response to climate change in Korea. This paper addresses this critical gap in the climate change literature by examining business organizations’ behaviors and identifying the factors influencing their actions. We employ statistical models to compare corporate climate change actions, and we explain their variations using survey data. The results indicate that despite increasing concerns about climate change, businesses have implemented very limited precautionary mitigation and adaptation actions. In addition, the concerns of the businesses about future climate change impact, organizational capacity (leadership, staff capacity, existence of a relevant division or department), and business size are significant factors with respect to the implementation of climate change actions.     

Twin-killing in some traditional societies: an economic perspective

Historically, some societies around the world killed newborn twins, though the practice was forsaken in the early twentieth century. Anthropologists have proposed different theses: (1) the delivery of twins occurred when the mother cheated on her husband, or committed a great sin, and killing the twins was the penalty, (2) twin-killing was done to assert that human beings were different from animals among which multiple births in the same delivery were seen, (3) twins brought a dilemma to the kinship structure of societies and to cope with it different rules were adopted, twin-killing being the extreme one, (4) twin-killing was a means to face resource stress. We argue that although those interpretations are useful, we can improve the understanding of that phenomenon by adding an identity economics model, where twins are a taboo. Identity economics helps us explain the persistence of the practice and its eventual decline. We make our case with examples from the Igbo of Nigeria.     

A metafrontier directional distance function approach to assessing eco-efficiency

This paper uses directional distance functions to extend the non-parametric metafrontier approach to efficiency measurement proposed by O’Donnell et al. (Empir Econ 34:231–255, 2008) to the assessment of technological differences in eco-efficiency between groups of producers. Furthermore, eco-efficiency is assessed at the level of specific environmental pressure management. This methodology is applied to a sample of Spanish olive producers that belong to both traditional mountain and traditional plain growing systems. We find great potential for both olive growing systems to reduce environmental pressures. In terms of pressures on natural resources, the most eco-efficient technology is the traditional plain system, while the traditional mountain system is the most eco-efficient when considering pressures on biodiversity. These results might help policymakers design strategies to improve the performance of olive growing and meet the demands of society regarding the economic and ecological functions of this farming activity.     

Disappearing investment-cash flow sensitivities: Earnings have not become a worse proxy for cash flow

According to a recent conjecture in the literature, earnings have become a poorer proxy for cash flow from operations over time. We find that since 1988, when cash flow statements started to be consistently reported in Compustat, the cash effectiveness of earnings has actually increased for a large sample of US manufacturing firms. This occurs despite the introduction of fair value accounting and increasing accounting accruals during the last three decades. Also contrary to the conjecture, using more comprehensive measures of cash flow does not restore the investment-cash flow sensitivity, which continues to be around 0.05 in more recent periods.     

Assessing Systemic Importance With a Fuzzy Logic Inference System

Three metrics are designed to assess Colombian financial institutions' size, connectedness and non-substitutability as the main drivers of systemic importance: (i) centrality as net borrower in the money market network; (ii) centrality as payments originator in the large-value payment system network; and (iii) asset value of core financial services. An aggregated systemic importance index is calculated based on expert knowledge by using a fuzzy logic inference system. We use principal component analysis to calculate a benchmark index for comparison purposes. Overall similarities between both indexes put forward that expert knowledge aggregation is consistent with that based on a purely quantitative standard approach. Specific non-negligible differences concur with the nonlinear features of an approach whose intention is to replicate human reasoning. Both indexes are complementary and provide a comprehensive relative assessment of each financial institution's systemic importance in the Colombian case, in which the choice of metrics pursues the macroprudential perspective of financial stability.

Strategic R&D investment,competitive toughness and growth

We show, within a single industry, the possibility that R&D‐investment is non‐monotonically related to competitive toughness: increasing when competition is soft and decreasing when competition is tough. This possibility results from the combination of a Schumpeterian markup squeezing effect discouraging innovation, and a concentration effect spurring innovators. It is obtained in a sectoral model where the number of innovators is random and where non‐successful investors may remain productive. The result is extended to a multisectoral stochastic endogenous growth model with overlapping generations of consumers and firms, the number of which is endogenously determined in the capital market.     

Economic Stagnation and Crisis in Korea during the Eighteenth and Nineteenth Centuries

In contrast to rapid economic growth in the twentieth century, Korea suffered a long economic decline in the eighteenth and nineteenth centuries, with the failure accelerating from 1850 to 1890. According to 36 different harvest records, rice productivity continuously declined from the early eighteenth to the late nineteenth centuries due to deforestation and increase in natural disasters. Contraction of rural markets after the interruption of trade with Japan also contributed to the decrease in rice production. The third reason for the nineteenth‐century crisis was the dissolution of the government‐led grain storage and redistribution system. Finally, the ultimate culprit for the crisis could be found in Confucianism with which the Joseon Dynasty was unable to properly understand and respond to the crisis.
