| Abstract: | We describe how a generic multi-period optimization-based decision support system (DSS) can be used for strategic planning in process industries. Built on five fundamental elements – materials, facilities, activities, time periods and storage areas – this DSS requires little direct knowledge of optimization techniques to be used effectively. It is user friendly and requires little knowledge of optimization. Results based on real data from a pharmaceuticals company in India demonstrate significant potential for improvements in revenues and profits. |

| Abstract: | The purpose of this article is to present two examples based on real life experiences where the Bullwhip effect in supply chain is considerably reduced. Both examples relate to the consumer durables industry in India. The first example uses Enterprise Resource Planning and Vendor Managed Inventory as tools to reduce the Bullwhip Effect. The second example uses a modification of the classical inventory control policies to eliminate Bullwhip Effect. Based on these two empirical case studies, we argue that managing Bullwhip Effect is a strategic initiative by organization and the best approach is a combination of several tactical initiatives. |

| Abstract: | This paper analyzes the behavior of horizontal B2B marketplaces along the supply chain in case a vertical intermediary tries to enter by attracting industry-specific buy-side and sell-side firms. It will be shown that an entrant can only integrate all firms along the vertical production chain in case the industry is strong buy-side dominated. For the remaining scenarios we will determine different levels of integration for buy-side and sell-side dominated branches, in which firms from upper stages will stay at the incumbent. Moreover, we will show that horizontal marketplaces for MRO and other simple goods will being driven out of the market in any case. |

| Abstract: | We report evidence from public goods experiments with and without punishment which we conducted in Russia with 566 urban and rural participants of young and mature age cohorts. Russia is interesting for studying voluntary cooperation because of its long history of collectivism, and a huge urban-rural gap. In contrast to previous experiments we find no cooperation-enhancing effect of punishment. An important reason is that there is substantial spiteful punishment of high contributors in all four subject pools. Thus, spite undermines the scope for self-governance in the sense of high levels of voluntary cooperation that are sustained by sanctioning free riders only. |
