    The foreign exchange exposure of UK non-financial firms: a comparison of market-based methodologies
    (Elsevier , 2013-09-30T00:00:00Z) Agyei-Ampomah, Sam; Mazouz, Khelifa; Yin, Shuxing
    We use a sample of 269 UK non-financial firms to study the sensitivity of foreign exchange exposure, and its determinants, to the different estimation methods. The standard Jorion's model suggests that 14.93% (30.50%) of the firms in our sample are exposed directly or indirectly to the fluctuations in the TWC (the US$, the Euro or the JP¥). However, the exposure increases substantially to 85.13% (96.65%) when time varying exposure regressions with orthogonalized market returns are used. We also show that the determinants of currency exposure are model-dependent. While the cross-sectional results suggest very little or no relationship between firm-specific factors and currency exposure, the explanatory power of these factors increase when data is pooled across firms and time.

    Underwriters' allocation with and without discretionary power: evidence from the Hong Kong IPO market
    (Elsevier, 2017-01-03) Mazouz, Khelifa; Mohamed, Abdulkadir; Saadouni, Brahim; Yin, Shuxing
    This study uses a unique and extensive data set from the Hong Kong IPO market to examine the theory of adverse selection under two distinct regulatory regimes in relation to underwriters' discretionary power in IPO share allocation. Consistent with Rock's (1986) theory of adverse selection in the IPO market, we show that, prior to the introduction of the clawback provision; retail (uninformed) investors were allocated more of the overpriced offerings and less of the underpriced issues. However, after the provision is implemented, retail investors have been allocated significantly more of the underpriced offerings and less of the overpriced ones. Overall, we find that allocation-adjusted initial returns for the retail investors are lower (higher) than the risk-free rate pre- (post-) clawback provision. These findings imply that the mandatory clawback provision has enhanced the fairness in IPO share allocations among different investor groups and has reduced the winner's curse in the IPO market.
