Abstract:
SummaryIn this paper we consider a two-stage duopoly game where firms first decide whether to invest in advertising and then compete in prices. Advertising has two effects: a market enlargement for both firms and a predatory gain for the investing firm only.Both symmetric and asymmetric equilibria may arise. The two most interesting cases are a coordination game where both firms investing and non-investing are equilibria, and a chicken game where only one firm invests while the other is possibly driven (endogenously) out of the market. Our results suggest that product differentiation has an am

Non-controlling major shareholders can effectively restrain controlling shareholders and management by exit threat, so as to participate in corporate governance.

This paper investigates the effects of members’ exits from a currency union on the credibility of the common currency.

Once an inflation rate of the common currency has been selected, each member decides whether to remain in the currency union or not. If a member decides to exit, it has to pay a fixed social cost and individually chooses the inflation rate of its currency. Unlike previous research on this to

To prevent biased advice, regulators increasingly ban commission payments to financial advisers. Such bans are associated with “advice gaps,” meaning that advice becomes less accessible. To understand the trade-off between the quality and accessibility of advice, this paper develops a model of price competition in advice markets with endogenous entry of advisers. While commission bans increase consumer surplus in the short run, they hurt the profitability of advisers. In the long run, advisers exit the market, advice becomes inaccessible, and consumer surplus decreases. These results imply tha

Endogenous regulation of translocation and of carbon partitioning, major factors for integrating plant function, depend on diurnal regulation of starch synthesis and mobilization.

Along with sugar sensing, the level and turnover of starch are involved in endogenous regulation in response to carbohydrate status. Despite their key roles in plant m

QE is modeled as one of the regimes. The model incorporates an exit condition for terminating QE. We find that higher reserves at the effective lower bound raise inflation and output, and that terminating QE may be contractionary or expansionary, depending on the state of the

Abstract:
ABSTRACT AFX-like Forkhead transcription factors, which are controlled by phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB) signaling, are involved in regulating cell cycle progression and cell death. Both cell cycle arrest and induction of apoptosis are mediated in part by transcriptional regulation of p27kip1. Here we show that the Forkheads AFX (FOXO4) and FKHR-L1 (FOXO3a) also directly control transcription of the retinoblastoma-like p130 protein and cause upregulation of p130 protein expression. Detailed analysis of p130 regulation demonstrates that following Forkhead-induced ce

Abstract:
Caenorhabditis elegans larvae can undergo developmental arrest upon entry into the dauer stage in response to suboptimal growth conditions. Dauer larvae can exit this stage in replete conditions with no reproductive consequence. During this diapause stage, the metabolic regulator AMP-activated protein kinase (AMPK) ensures that the germ line becomes quiescent to maintain germ cell integrity. Animals that lack all AMPK signalling undergo germline hyperplasia upon entering dauer, while those that recover from this stage become sterile.

ABSTRACT Mechanisms coordinating neural progenitor cell cycle exit and differentiation are incompletely understood. The cyclin-dependent kinase inhibitor p27Kip1 is transcriptionally induced, switching specific neural progenitors from proliferation to differentiation. However, neuronal differentiation-specific transcription factors mediating p27Kip1 transcription have not been identified. We demonstrate the homeodomain transcription factor Phox2a, required for central nervous system (CNS)- and neural crest (NC)-derived noradrenergic neuron differentiation, coordinates cell cycle exit and diffe

During its initial folding in the endoplasmic reticulum (ER), newly synthesized thyroglobulin (Tg) is known to interact with calnexin and other ER molecular chaperones, but its interaction with calreticulin has not been examined previously. In the present study, we have investigated the interactions of endogenous Tg with calreticulin and with several other ER chaperones. We find that, in FRTL-5 and PC-Cl3 cells, calnexin and calreticulin interact with newly synthesized Tg in a carbohydrate-dependent manner, with largely overlapping kinetics that are concomitant with the maturation of Tg intrac

ABSTRACT Protein kinase B (PKB/Akt) is an important modulator of insulin signaling, cell proliferation, and survival. Using small interfering RNA duplexes in nontransformed mammalian cells, we show that only Akt1 is essential for cell proliferation, while Akt2 promotes cell cycle exit. Silencing Akt1 resulted in decreased cyclin A levels and inhibition of S-phase entry, effects not seen with Akt2 knockdown and specifically rescued by microinjection of Akt1, not Akt2. In differentiating myoblasts, Akt2 knockout prevented myoblasts from exiting the cell cycle and showed sustained cyclin A expres

We estimate the value of competition in United States Forest Service (USFS) timber auctions, in the context of the Reagan administration's bailout of firms that faced substantial losses on existing contracts. We use a model with endogenous entry by asymmetric firms, allowing survivors to respond to the exit of bailed-out firms by entering more auctions and for these marginal entrants to have lower values than firms that would choose to enter in any event, a selective entry effect. Observed asymmetries and selective entry contribute to us finding that the bailout may have increased USFS revenue

We develop a theory of commodity taxation featuring imperfect competition along with love-of-variety preferences and endogenous firm entry and exit. We derive new formulas for the efficiency and pass-through of specific and ad valorem taxes. These formulas unify existing canonical ones and feature a new term capturing the effect of variety on consumer surplus. As a proof of concept, we use theoretical formulas to identify love-of-variety preferences in an empirical application. Our welfare analysis shows that the marginal excess burden is sensitive to the estimated love of variety, which overt

ABSTRACT p73 is a recently described member of the p53 family, and, like p53, it undergoes a number of posttranslational modifications. Here we show, by yeast two-hybrid screening, pull-down assays, and coimmunoprecipitation, that p73α, -β, and -γ bind to the protein inhibitor of activated STAT-1 (PIAS-1) and that this binding stabilizes p73. PIAS-1 also sumoylates p73α, although not the C-terminally truncated isoforms p73β and -γ, and this requires the RING finger domain of PIAS-1. The ΔNp73α isoform can also bind, and be sumoylated by, PIAS-1. PIAS-1-mediated sumoylation decreases p73 transc

The ubiquitin ligase anaphase-promoting complex/cyclosome (APC/C) is activated at prometaphase by mitotic phosphorylation and binding of its activator, Cdc20. This initiates cyclin A degradation, whereas cyclin B1 is stabilized by the spindle checkpoint. Upon checkpoint release, the RXXL destruction box (D box) was proposed to direct cyclin B1 to core APC/C or Cdc20. In this study, we report that endogenous cyclin B1–Cdk1 is recruited to checkpoint-inhibited, phosphorylated APC/C in prometaphase independently of Cdc20 or the cyclin B1 D box.

Abstract I develop a model of venture capital (VC) intermediation that quantitatively explains central empirical facts about VC activity and can evaluate its macroeconomic relevance. The impact of VC-backed innovations is significantly larger than suggested by observed aggregate venture exit valuations, even after accounting for large exposures to systematic and uninsurable idiosyncratic risks. The risk properties of venture capital play a quantitatively important role in both explaining empirical regularities and shaping the value of ventures’ contributions to economic growth.
