Asset price volatility in a nonconvex general equilibrium model

Summary. Asset prices and returns are known to vary significantly more than␣output or aggregate consumption growth, and an order of magnitude in excess of what is justified by innovations to fundamentals. We study excess price volatility in a lifecycle economy with two assets (claims on capital and␣a public debt bubble), heterogeneous agents, and increasing returns to financial intermediation. We show that a relatively modest nonconvexity generates a set valued equilibrium correspondence in asset prices, with two␣stable branches. Price volatility is the outcome of an equilibrium selection mechanism, which mixes adaptive learning with “noise”, and alternates stochastically between the two stable branches of the price correspondence.

Foreign direct investment and growth in India: a cointegration approach

The two-way link between foreign direct investment and growth for India is explored using a structural cointegration model with vector error correction mechanism. The existence of two cointegrating vectors between GDP, FDI, the unit labour cost and the share of import duty in tax revenue is found, which captures the long run relationship between FDI and GDP. A parsimonious vector error correction model (VECM) is then estimated to find the short run dynamics of FDI and growth. Our VECM model reveals three important features: (a) GDP in India is not Granger caused by FDI; the causality runs more from GDP to FDI; (b) trade liberalization policy of the Indian government had some positive short run impact on the FDI flow; and (c) FDI tends to lower the unit labour cost suggesting that FDI in India is labour displacing.     

Structural Analysis of a Developing Economy Using the Conventional and Augmented Input-Output Matrix Methods — A Comparison for Sri Lanka

This paper explains why and how the conventional Input-Output Method should be modified to develop the Augmented Input-Output Matrix Method in order to study the structure of a developing economy using Multiplier and Linkage Analysis. This alternative methodology with an endogenous Household Sector is expected to provide a better picture of the structure of the economy by treating demand as partially endogenous and allowing for induced linkage effects transmitted across various sectors of the economy. In contrast, such induced linkage effects are absent in the conventional methodology which is based on the technical relationships of production alone.

Applying the two methods on the economy of Sri Lanka using the Input-Output Tables for 1986 and 1994, we find that the Augmented Input-Output Matrix Method changes the relative importance of the various sectors in terms of their output multipliers and backward linkage strengths, for each of the two years. Overtime, however, the Augmented Input-Output Matrix Method shows less variations in the multipliers, linkages and the resulting key sectors of the economy while rendering the economy more traditional and service-oriented in character. Manufacturing and allied sectors are more often absent than present among the strong or key sectors of the economy.

Economic Liberalization was initiated in the 1970’s in Sri Lanka. But the economy has not yet experienced any fundamental change in its structure. The results of the Augmented Matrix Method suggest that the economy should be more diversified and modernized in order to fully reap the benefits of liberalization in terms of economic growth.

     

Export-led Growth and Import Compression: Further Time Series Evidence From LDCs

This paper conducts tests of the export-led growth and the import-compression hypotheses for four less developed countries (LDCs) – India, Nigeria, Fiji and Papua New Guinea (PNG). Based on Johansen's multiple cointegration test preceded by unit root tests, we test for cointegration between real output, exports and imports. Non-rejection of cointegration between the variables excludes the possibility of Granger non-causality and suggests at least one way Granger causality. Real output, exports and imports are found to be cointegrated in two of the countries and the resulting error-correction models suggest that Granger causality runs from exports and imports to real output in these cases. Exogeneity tests are conducted for exports with respect to real output. However, while the assumption of weak exogeneity is validated in two of the countries, the null hypothesis of super exogeneity is rejected. The test results therefore cast doubts on policy recommendations for the LDCs based on the export-led growth hypothesis.     

Household Food Insecurity and Maternal and Child Nutritional Status: Evidence from Maharashtra

In this paper we rigorously examine the association of household food security status with maternal and child nutritional status exploring a rich micro‐level database, the Comprehensive Nutrition Survey Maharashtra 2012. Using Household Food Insecurity Access Scale (HFIAS) as a metric to measure household food security, we apply simultaneous probit models to estimate the effect of food insecurity on maternal and child nutritional outcomes. The modelling framework addresses possible endogeneity in the above relationship. Findings indicate that household food insecurity increases the risk of maternal and child underweight with no effect on child stunting, wasting or maternal overweight. Women’s decision‐making power mediates these associations. Food security interventions should be effective in tackling the concerns with undernutrition, however, food alone is not the solution. A mix of nutrition‐specific and nutrition‐sensitive policies is warranted. Food security interventions should be integrated into policies for human development.     

Does shareholder coordination matter? Evidence from private placements

We propose a new role for private investments in public equity (PIPEs) as a mechanism to reduce coordination frictions among existing equity holders. We establish a causal link between the coordination ability of incumbent shareholders and PIPE issuance. This result obtains even after controlling for alternative explanations such as information asymmetry and access to public markets. Improved equity coordination following a private placement leads to favorable debt renegotiations within one year of issuance. Mitigating coordination frictions among shareholders ultimately decreases the odds of firm default in half.     

On the Mean of Squared Deprivation Gaps

This paper provides an axiomatic characterization of the mean of squared deprivation gaps, which is a distinguished member of the important class of deprivation measures first introduced by Foster et al. (Econometrica 16(1):761–766, 1984) and which has been extensively used in applied work on deprivation. We are grateful to Salvador Barberà and Buhong Zheng for helpful comments on an earlier version of the paper.     

Efficiency and Equity in School Funding: A Case Study for Kansas

This study measures cost inefficiency of Kansas public school districts and applied both mathematical programming and stochastic frontier approach. The empirical study uses two-stage data envelopment analysis model and the cost inefficiency effects model proposed by Battese and Coelli (Empirical Economics 24:325–332, 1995) and applied to a panel data. The results found mean inefficiencies from these two models are very close. The results indicate that Kansas school districts, on average, exhibit cost inefficiency in their operations, however, there is a tendency for inefficiencies to decline over time. The study does not find any strong evidence for lower efficiency due to lower expenditure per-pupil. Instead, we found inconclusive evidences where lower efficiency for certain school districts could be assigned to unfavorable environmental cost conditions.

Hartman's quandary: Reconciling pluralism and realism for virtue ethics in business

There is considerable consensus on the idea that Aristotelian virtue ethics advocates moral realism. In numerous works, the well-known business ethicist Edwin Hartman grapples with reconciling the unitary vision of life that a particular kind of moral realism advocates and the pluralist respect for diverse cultures and belief systems that comprise our world. This paper closely follows Hartman's efforts to reconcile his liberal values with his guarded support for Aristotelian moral realism. We argue that the realist interpretation of Aristotle's function argument can be employed to strengthen Hartman's critique of the concept of Homo economicus, which is often posited by its proponents and critics alike as the only viable position for a business manager. Drawing from Aristotle, the paper posits a novel notion of species-excellence as the ultimate telos of human life and an objective basis for a critique of Homo economicus.     

Corporate social responsibility and litigation risk: Evidence from securities class action lawsuits

This study examines whether corporate social responsibility (CSR) is associated with the likelihood and outcomes of securities class action lawsuits. We find a lower likelihood of securities litigation for firms with higher CSR. This effect is larger for companies with lower levels of financial distress, companies with larger proportions of institutional investors, and for internal CSR. Additionally, CSR has a mitigating effect on negative market assessments around the filing dates of securities litigation. The results suggest that higher CSR firms are less likely to engage in financial misconduct, and investors are less likely to penalise them for such occurrences.
