The Effect of Oil Prices on Field Production: Evidence from the Norwegian Continental Shelf

I use detailed field‐level data on Norwegian offshore oil production and a semi‐parametric additive model to control for the production profile of fields to estimate the effect of oil prices on production. I find no significant evidence of a concurrent reaction of field production to oil prices, though a modest lagged effect is found of the magnitude of approximately 2% to 7% for a $10 per barrel increase in the real price of oil.     

How real people make long-term decisions: The case of retirement preparation

Large variations in retirement wealth are common, with some households accumulating hundreds of thousands of dollars and others accumulating next to nothing. We examine to what extent formal planning or simple rules of thumb contribute to these differences in wealth accumulation. In particular, we investigate whether those who follow simple rules of thumb or those who come up with more complete plans accumulate more wealth than those who take an unsystematic approach. We test this empirically using a specifically designed survey about retirement preparation. We find that people who rely on a rule of thumb behave like literal planners. However, people without any systematic approach save substantially less. Our results, taken together with evidence from psychology, suggest that financial planning advice based on simple rules of thumb may be helpful for those who currently take no systematic approach.     

Using export market performance to evaluate regional preferential policies in China

We evaluate the effectiveness of two types of preferential regional policy programs in China’s manufacturing sector. The primary goal of the Economic and Technological Development Zones (ETDZs) is to facilitate internationalization strategies, while Science and Technology Industrial Parks (STIPs) aim to generate technology spillovers. Various dimensions of export market performance are used as objective indicators for the upgrading of product quality and firm operations. We compare startups that locate into one of these zones with startups on the outside, while controlling for self-selection using treatment evaluation methods. The results indicate that firms locating in an ETDZ achieve much higher export values, driven by higher volumes of trade and numbers of destinations. Firms locating in a STIP perform best on quality dimensions. In particular they fetch higher export prices and have more success exporting to high-income countries.     

Within-person variation in affective commitment to teams: Where it comes from and why it matters

Teamwork is crucial to organizational success and commitment to teams is an important predictor of team-related behaviors. However, theorists and researchers have typically assumed that commitment levels are generally stable within-persons, increasing or decreasing as a result of substantial organizational changes. This position is at odds with the evidence of systematic and regular intraindividual fluctuations in personal attributes and workplace behaviors. We draw upon affective events theory to present a model explaining how certain events and dispositions produce vacillations in affective reactions which, in turn, are likely to create within-person variation in affective commitment to teams (WPVC_teams). We further propose that WPVC_teams enhances prediction and explanation of intraindividual fluctuations in work behavior and, interindividually, moderates the relationship between level of commitment and behavior.     

Limits of semistatic trading strategies

We show that pointwise limits of semistatic trading strategies in discrete time are again semistatic strategies. The analysis is carried out in full generality for a two-period model, and under a probabilistic condition for multiperiod, multistock models. Our result contrasts with a counterexample of Acciaio, Larsson, and Schachermayer, and shows that their observation is due to a failure of integrability rather than instability of the semistatic form. Mathematically, our results relate to the decomposability of functions as studied in the context of Schrödinger bridges.
