Analytical frameworks of government service contracting decisions typically focus on the make-or-buy decision. In concepts, governments can either produce the service itself (make) or outsource production (buy). However, governments make and buy the same public services, a practice that is termed concurrent sourcing. Drawing on transaction costs economics and the resource-based view of the firm, this article examines empirically local governments’ propensities to concurrently source public services. Using a unique data set on water public services of more than 4,500 French municipalities for four years—1998, 2001, 2004, and 2008—we find that low transaction hazards, prior contracting experience, and low production capabilities have a positive impact on the level of concurrent sourcing. These findings demonstrate that organizations’ characteristics are a significant factor in sourcing decisions and suggest that capabilities and their interactions with transaction hazards deserve heightened attention in the study of public contracting.

As market intermediaries, electricity retailers buy electricity from the wholesale market or self-generate for re(sale) on the retail market. Electricity retailers are uncertain about how much electricity their residential customers will use at any time of the day until they actually turn switches on. While demand uncertainty is a common feature of all commodity markets, retailers generally rely on storage to manage demand uncertainty. On electricity markets, retailers are exposed to joint quantity and price risk on an hourly basis given the physical singularity of electricity as a commodity. In the literature on electricity markets, few articles deal on intra-day hedging portfolios to manage joint price and quantity risk whereas electricity markets are hourly markets. The contributions of the article are twofold. First, we define through a VaR and CVaR model optimal portfolios for specific hours (3 am, 6 am,. . . ,12 pm) based on electricity market data from 2001 to 2011 for the French market. We prove that the optimal hedging strategy differs depending on the cluster hour. Secondly, we demonstrate the significantly superior efficiency of intra-day hedging portfolios over daily (therefore weekly and yearly) portfolios. Over a decade (2001–2011), our results clearly show that the losses of an optimal daily portfolio are at least nine times higher than the losses of optimal intra-day portfolios.
