Brand-Pack Size Cannibalization Arising from Temporary Price Promotions

This study investigates how price promotions for one pack-size of a brand steal sales from the other pack-sizes of the same brand. To do so, the study examines twelve grocery product categories (seven US, three UK, two Australian). The analysis finds heavy cross-pack cannibalization. On average, 22 percent of the sales uplift for a promoted brand-pack size comes from other pack sizes of the same brand. Cross-pack cannibalization most typically occurs in the week of the promotion, but also transfers future week's sales away from the non-promoted pack size in 31 percent of cases. The study finds higher cannibalization is associated with packs that sell for a higher dollar value than others sold under the same brand; whereas higher price-per-weight, a packaging difference, and the item having a larger relative share of sales in the brand portfolio, are linked to lower cannibalization. Also examined is the impact of pack-size cannibalization on promotion profitability for retailer PLs. That analysis finds PL price promotions have generally negative impacts on PL profits, and that pack-size cannibalization exacerbates this negative outcome. The results suggest both retailers and manufacturers should carefully consider pack-size cannibalization when evaluating the outcome of temporary price promotions. The study also provides some evidence-based recommendations from which managers can attempt to minimize such cannibalization.     

Signalling with official interest rates: the case of the German discount and lombard rate

A major characteristic of the operating procedure of the European Central Bank (ECB) is its reliance on standing facilities. It is intended that the official rates on those facilities also serve the function of signalling. The case of Germany, where the Bundesbank followed a similar signalling strategy, is analysed. In particular the paper investigates whether announcements of official interest rates provide information not already contained in other policy measures and whether the resulting revisions of expectations are efficient. Significant differences are found between signalling in the case of increasing and decreasing interest rates.     

Stability of international stock market relationships across month of the year and different holding intervals

Potential benefits from international diversification depend upon the stability in stock market relationships. Using monthly data of 11 international stock markets, this paper examines the stability in stock market relationships across month of the year and across different holding intervals. Empirical results show that the correlation structure is more stable than the covariance structure. While empirical evidence supports the hypothesis that the correlation structure is very stable across different holding intervals, the empirical support for the stability in correlation structure across month of the year is much weaker.     

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.     

CONSTANT PROPORTION PORTFOLIO INSURANCE IN THE PRESENCE OF JUMPS IN ASSET PRICES

Constant proportion portfolio insurance (CPPI) allows an investor to limit downside risk while retaining some upside potential by maintaining an exposure to risky assets equal to a constant multiple of the cushion , the difference between the current portfolio value and the guaranteed amount. Whereas in diffusion models with continuous trading, this strategy has no downside risk, in real markets this risk is nonnegligible and grows with the multiplier value. We study the behavior of CPPI strategies in models where the price of the underlying portfolio may experience downward jumps. Our framework leads to analytically tractable expressions for the probability of hitting the floor, the expected loss, and the distribution of losses. This allows to measure the gap risk but also leads to a criterion for adjusting the multiplier based on the investor's risk aversion. Finally, we study the problem of hedging the downside risk of a CPPI strategy using options. The results are applied to a jump-diffusion model with parameters estimated from returns series of various assets and indices.     

Self-regulation and moral awareness among entrepreneurs

Moral awareness underpins moral reasoning and ethical decision making. This mixed methods study investigates a critical feature of these phenomena among entrepreneurs, namely the influence of social cognitive self-regulation on moral awareness. Results suggest that entrepreneurs with stronger self-regulatory characteristics are more morally aware and relate such awareness to maintaining personal integrity and building inter-personal trust. In contrast, entrepreneurs with weaker self-regulatory characteristics appear less morally aware overall, and focus primarily on moral issues relating to failure and loss. I conclude the paper by discussing the implications for future research and practice.
