Consumption smoothing and portfolio rebalancing: The effects of adjustment costs

A household's response to income and return shocks depends on the costs of portfolio adjustment. In particular, the extent of portfolio rebalancing and consumption smoothing are influenced by the presence of non-convex portfolio adjustment costs. Suppose bonds can be adjusted costlessly while adjustments to stock accounts entail adjustment costs. Due to these portfolio adjustment costs, the household demands both stocks and bonds. A household can buffer some income fluctuations without incurring adjustment costs and engage in costly portfolio rebalancing less frequently. Using the estimated preference parameters and portfolio adjustment costs, the response to income and return shocks is nonlinear and reflects the interaction of portfolio rebalancing and consumption smoothing.     

The efficacy and efforts of interest groups in post elections policy formation

This paper presents a new model of interest groups and policy formation in the legislature. In our setting, the already given party ideological predispositions and power distribution determine the expected policy outcome. Our analysis applies to the case of un-enforced or enforced party discipline as well as to two-party and multi-party (proportional representation) electoral systems. The interest groups’ objective is to influence the outcome in their favor by engaging in a contest that determines the final decision in the legislature. Our first result clarifies how the success of an interest group hinges on the dominance of its ideologically closer party and, in general, the coalition/opposition blocks of parties under un-enforced party or coalition/opposition discipline. Such dominance is defined in terms of ideological inclination weighted by power. Our second result clarifies how the success of an interest group hinges on the dominance of its ideology in the ruling coalition (party) in a majoritarian system with enforced coalition (party) discipline. We then clarify under what condition an interest group prefers to direct its lobbying efforts to two parties or the two coalition and opposition blocks of parties under un-enforced discipline rather than to the members of the ruling coalition (party) under enforced discipline. The lobbying efforts under un-enforced and enforced party discipline are also compared. Finally, we clarify the effect of ideological predispositions and power on the efforts of the interest groups.     

Estimating the elasticity of intertemporal substitution accounting for stockholder-specific portfolios

This article estimates the elasticity of intertemporal substitution using stockholder actual return experience. The approach is motivated by numerous data sources indicating that the median US stockholder has a portfolio composed of only three or four individual stocks, rather than a well-diversified portfolio as suggested by portfolio theory. Therefore, representing an individual stockholder portfolio by a proxy financial index (the common approach taken in the literature) may be too rough an approximation of investor behaviour and lead to biased results about risk aversion and intertemporal substitution. Eschewing the financial index methodology, our results support the standard representative agent assumption that there is a high degree of homogeneity in the elasticity of intertemporal substitution across stockholders with different wealth levels. Our findings have implications for models that assess the comovement between consumption and return on stocks.     

Concentration in Asia's cross-border banking: Determinants and impacts

Cross-border bank positions in Asia and the Pacific remain highly concentrated among a few counterparties, exposing the region to financial risks and policy spillovers. Consequently, assessing the determinants and impacts of the region's cross-border banking concentration is relevant to the design of appropriate policies for promoting financial development and safeguarding financial stability. To this end, we construct cross-border bank concentration measures for 47 economies in Asia and the Pacific from 2000 to 2019. The results show that higher capital account and trade openness and per capita income are significantly associated with lower cross-border bank concentration. Moreover, elevated cross-border bank concentration tends to lower domestic credit and nonperforming loans. We find no impact on bank profitability for the region.
