This paper empirically investigates the out‐of‐sample performance of the 1/N naive rule and the Markowitz mean–variance strategies in the largest emerging market (i.e., China's A‐shares market) and provides three new findings. First, we show that som... Read More about Optimal and naive diversification in an emerging market: Evidence from China's A‐shares market.

Firms are encouraged to continually initiate innovation activities as part of their new product development processes and to be open to the use of external knowledge sources. Yet, many are abandoned. Openness to external knowledge sources and the exp... Read More about Abandoning Innovation Activities and Performance: The moderating role of openness.

The Measurement of Absorptive Capacity from an Economics Perspective: Definition, Measurement and Importance (2018)
Journal Article

This paper starts by recognizing that despite the importance of absorptive capacity, economists in particular have made only limited use of the concept. Most theoretical and empirical studies derive from other fields of research. Thus, the first task...

We present resource‐based and capability‐based arguments of marketing investment intensity to offer a strategic view of marketing as an investment in shareholder value. We find that marketing investment intensity has a U‐shaped quadratic effect on sh... Read More about Marketing as an Investment in Shareholder Value.

As consumers exhibit relatively more self-control over healthy products by limiting the purchase quantity of vice choices and buying more virtue choices to adhere to healthy-eating goals, a price promotion has a stronger effect on virtue than vice ch...

Asymmetric Demand Patterns for Products with Added Nutritional Benefits and Products without Nutritional Benefits (2016)
Journal Article
