We develop models for portfolio diversification in the sovereign credit default swap (CDS) markets and show that, despite literature findings that sovereign CDS spreads are affected by global factors, there is sufficient idiosyncratic risk to be diversified away. However, we identify regime...

This paper explores how the medical expenditure risk affects the households' portfolio choice across health status theoretically in a life cycle model and empirically using machine learning methods. Medical expenditure risk, as a background risk, can relocate households' financial decisions. A...

We examine the allocation of a limited pool of matching funds to public good projects using Quadratic Funding. In particular, we consider a variation of the Capital Constrained Quadratic Funding (CQF) mechanism proposed by Buterin, Hitzig and Weyl (2019) where only funds in the matching pool are...

Banks must manage their trading books, not just value them. Pricing includes valuation adjustments collectively known as XVA (at least credit, funding, capital and tax), so management must also include XVA. In trading book management we focus on pricing, hedging, and allocation of prices or...

In this paper I examine some of the properties of the mechanism proposed by Buterin, Hitzig, and Weyl (2019) for public goods financing, under a limited pool of matching funds. I explore questions to understand under which conditions social efficiency will most likely be compromised, such as for...

This paper provides a model which helps explain the variability of stock liquidity premium. I model liquidity as a time-varying price impact and include both permanent as well as temporary price impact. Liquidity premium is defined as an additional return that stock should yield to compensate an...

Climate change poses an existential threat. The authors argue that carbon pricing and green research and development (R&D) support are good economics, but their implementation can be improved. Even if carbon prices are generalized and given more substance, green R&D is still likely to be smaller...

Why are there so few women in finance and even fewer managing funds? There is a major discrepancy between the number of female and male fund managers worldwide. The aim of this paper is to ascertain if gender is a contributing factor to fund managers’ performance. This is examined through...

The paper gives conditions for dynamic inefficiency of laissez-faire allocations in an overlapping-generations model with safe and risky assets. If the rate of population growth is certain, the conditions given depend only on how the rate of return on safe assets compares to the growth rate. If...
