Abstract This supplement provides supporting material for Lam et al. We briefly summarize past gravitational microlensing searches black holes (BHs) and present details of the observations, analysis, modeling five BH candidates observed with both ground-based photometric surveys Hubble Space Telescope astrometry photometry. detailed results four that show no or low probability lens to be a BH. ...

This paper investigates the determinants of vertical integration and confronts some of the predictions of the leading approach to the internal organization of the firm with data from the UK manufacturing sector. Consistent with the theory, it shows that an upsteam and downstream activity pair are more likely to be vertically integrated, when the downstream (the producer) is more technology inte...

The proteins of the large subunit of rat liver ribosomes were separated into seven groups by stepwise elution from carboxymethylcellulose with LiCl at pH 6.5. Seventeen proteins (L4, L5, Li’, L9, Lll, L12, L13, L21, L22, L23, L26, L27, L30, L33, L35’, L37, and L39) were isolated from three of the groups (B60, D60, G60) by ion exchange chromatography on carboxymethylcellulose and by filtration t...

The herein study presents an explanation of the high frequency of team production and high level of peer monitoring found in Japanese firms, in terms of a simple and empirically grounded variation in individual utility functions. We argue that Japanese agents are generally characterized by a higher degree, with respect to their Western counterparts, of aversion to unfavourable inequality, a fea...

An unbiased photo-cross-linking approach was used to probe the "molecular path" of a growing nascent Escherichia coli inner membrane protein (IMP) from the peptidyl transferase center to the surface of the ribosome. The nascent chain was initially in proximity to the ribosomal proteins L4 and L22 and subsequently contacted L23, which is indicative of progression through the ribosome via the mai...

We have sequenced a previously uncharacterized region of the Bacillus subtilis S10 ribosomal protein gene cluster. The new segment includes genes for S10, L3, L4, L23, L2, S19, L22, S3, and part of L16. These B. subtilis genes map in the same order as the genes in the Escherichia coli S10 ribosomal protein operon. Two potential promoter sequences were identified, one approximately 200 bases and...

We survey an emerging literature at the intersection of organizational economics and international trade. We argue that a proper modelling of the organizational aspects of production provides valuable insights on the aggregate workings of the world economy. In reviewing the literature, we describe certain predictions of standard models that are a¤ected or even overturned when organizational dec...

We investigate the effects of contract renegotiation in multi-agent situations where risk averse agents negotiate a contract offer to the principal after the agents observe a common, unverifiable perfect signal about their actions. We show that renegotiation with multiple agents reduces the cost of implementing any implementable action profile down to the first-best level, even though the princ...

Sabotage in Tournaments: Evidence from a Laboratory Experiment Although relative performance schemes are pervasive in organizations reliable empirical data on induced sabotage behavior is almost non-existent. We study sabotage in tournaments in a controlled laboratory experiment and are able to confirm one of the key insights from theory: effort and sabotage increase with the wage spread. Addit...
