Diagnostic features.
Ramose repent sponge. Bluish green in life, pale white in alcohol. Oscula are small, 2–4 mm in diameter. Ectosomal shows reticulation fiber tract. Oxeas slightly curved, larger oxeas 120.3–171.3 (139.4) × 4.8–9.3 (6.1) µm (n = 22), thin oxeas 109.3–132.7 (121) × 2.4–5.3 (3.5) µm (n = 14). Microscleres are C-shaped sigmas. This specimen is identified as Niphates nitida due to the reticulation fiber tract on the skeleton and the present of sigmas. Previously, only two species of Niphates recorded from Indonesia. Niphates laminaris Calcinai et al., 2017 is characterized by a non-spiny, rather irregular, microconulose surface and a chaonosomal skeleton with primary and secondary reticulation fiber tracts, as well as numerous microscleres (Calcinai et al. 2017). Niphates olemda (de Laubenfels, 1954) is a tubular sponge with small oxeas (de Laubenfels 1954). Niphates nitida is a new record for Indonesia.
Distribution and ecology.
Previously was reported from Magnetic Island, Australia (Fromont 1993). This is first record for the Spermonde Archipelago (at Kayangan Island; turbid environment).

description: We study theoretically and experimentally a committee with common interests. Committee members do not know which of two alternatives is the best, but each member can acquire
privately a costly signal before casting a vote under either majority or unanimity rule. In the experiment, as predicted by Bayesian equilibrium, voters are more likely to acquire information under majority rule, and attempt to counter the bias in favor of one alternative under unanimity rule. As opposed to Bayesian equilibrium predictions, however, many committee members vote when uninformed. Moreover, uninformed voting is strongly associated with a lower propensity to acquire information. We show that an equilibrium model of subjective prior beliefs can account for both these phenomena, and provides a good overall fit to the observed patterns of behavior both in terms of rational ignorance and biases.

description: Long-term breeding bird censuses on the Faroese Island of Skúgvoy showed differing trends of declining seabird populations and more stable terrestrial birds. To examine the population trends from 1961 to 2023 using periodic breeding bird censuses on Skúgvoy, in the Faroe Islands, encompassing most terrestrial and marine species. Skúgvoy is the only Faroese Island with periodic bird censuses, conducted since 1961 at approximately 20-year intervals, with a new census in 2023. Inland birds were counted by mapping breeding territories, with colonial seabirds counted individually on cliff ledges from the sea surface. These historical censuses provided a long-term quantitative assessment of species’ population dynamics and exploration of potential causes of observed declines, especially among seabirds. Seabird populations have not only declined drastically since the previous comprehensive census in 2001 but have also experienced acceleration in the scale of decline. In contrast, terrestrial species have exhibited only minor fluctuations. The differing trends between seabirds and inland birds suggest that the declines are likely driven by regional-scale processes, such as reduced food availability for pelagic seabirds, rather than local-scale processes operating within the island system.
External Validation of Voter Turnout Models by Concealed Parameter Recovery

description: We conduct a model validation analysis of several behavioral models of voter turnout, using laboratory data. We call our method of model validation concealed parameter recovery, where estimation of a model is done under a veil of ignorance about some of the experimentally controlled parameters — in this case voting costs. We use quantal response equilibrium as the underlying, common structure for estimation, and estimate models of instrumental
voting, altruistic voting, expressive voting, and ethical voting. All the models except the ethical model recover the concealed parameters reasonably well.  We also report the results of a counterfactual analysis based on the recovered parameters, to compare the policy implications of the different models about the cost of a subsidy to increase turnout.

Quantal Response and Nonequilibrium Beliefs Explain Overbidding in Maximum-Value Auctions
Creators: name: Camerer, Colin F.
name: Nunnari, Salvatore
name: Palfrey, Thomas R.
Publisher: name: California Institute of Technology
Year: 2014

description: We report an experiment on a simple common value auction to investigate the extent to which bidding can be explained by quantal response equilibrium, in combination with different
assumptions about the structure of bidder beliefs|the cursed equilibrium model and models that posit levels of strategic sophistication. Using a structural estimation approach, we find a close correspondence between the theoretical predictions of those models and experimental
behavior. The basic pattern of average bids in the data consists of a combination of overbidding for low signals, and value-bidding for higher signals. The logit QRE model with heterogeneous bidders fits this pattern reasonably well. Combining quantal response with either cursed beliefs (CE-QRE) or a level-k of strategic sophistication (LK-QRE, CH-QRE) leads to a close match with the data. All these variations on quantal response models predict minimal differences of average bidding behavior across different versions of the game, consistent with the experimental
findings. Finally, we reanalyze data from an earlier experiment on the same auction by Ivanov, Levin and Niederle (2010). While their data exhibit much more variance compared with ours, nonetheless, we still find that these models also fit their data reasonably well, even in the presence of extreme overbidding observed in that experiment. Overall, our study indicates that the winner curse phenomenon in this auction is plausibly attributable to limits on strategic thinking combined with quantal response.

The Dynamic Free Rider Problem: A Laboratory Study

Publisher: name: California Institute of Technology
Year: 2013
Subjects: Durable public goods, voluntary contribution mechanism, experiments

description: We report the results from an experiment designed explicitly to study the Markov Perfect Equilibrium (MPE) dynamics of free riding behavior in the accumulation of a durable public good. We consider two cases: economies with reversibility (RIE), where the agents can either increase or decrease the accumulated stock; and economies with irreversibility (IIE), where contributions are non-negative. Our findings support the key qualitative prediction of MPE: IIE converges to an accumulated level of public good that is an order of magnitude higher than RIE. We also find that the accumulation path is inefficiently slow in both RIE and IIE, and the public good is significantly under-provided.

description: We analyze conditions under which candidates' reputations may affect the beliefs of the voters over what policy will be implemented by the winning candidate of an election. We develop a model of repeated elections with complete information in which candidates are purely ideological. We analyze an equilibrium in which voters' strategies involve a credible threat to punish candidates who renege of their campaign promises, and all campaign promises are believed by voters, and honored by candidates. We characterize the maximal credible campaign promises and obtain that the degree to which promises are
credible in equilibrium is an increasing function of the value of a candidate's reputation.

Pious Bequests in Wills: A Statistical Analysis
Creators: name: Hoffman, Philip T.
Publisher: name: California Institute of Technology
Year: 1981

description: This paper employs maximum likelihood methods to analyze the increase in pious bequests in early modern French wills. Other historians have described the rise of pious bequests in wills, but no one has used multivariate statistical methods to explain the phenomenon. It turns out that at any level of wealth pious bequests rose over the course of the seventeenth century and that the bequests were most pronounced among the literate and women. The paper argues that the increase in pious bequests was mark of growing support for the Counter Reformation, which attracted an inordinate number of supporters in educated circles and in the female population.

Social History and Taxes: the Case of Early Modern France
Creators: name: Hoffman, Philip T.
Publisher: name: California Institute of Technology
Year: 1983

description: [Introduction] Apart from a flurry of interest in tax revolts ten years ago, social historians of early modern Europe have by and large ignored taxation. Their neglect is perhaps understandable, given that social history itself arose as a revolt against traditional political history and all that it entailed, including the operations of the fisc. The fact that details of early modern fiscal systems often lie interred in tedious administrative histories or that many political historians themselves seem to overlook matters of interest to social historians of course only compounds the problem.

description: In deutschsprachigen Medien sind Wissenschaftlerinnen deutlich unterrepräsentiert – ein Umstand, auf den die Akteur*innengruppe der Hochschulkommunikation Einfluss nehmen kann. An der Schnittstelle zwischen Hochschule und Gesellschaft tätig, entscheidet sie mit, welche Forschung und welche Forschenden sichtbar gemacht werden.

Um die Sichtbarkeit von Wissenschaftlerinnen zu erhöhen, ist es notwendig, dass Kommunikationsverantwortliche ihre eigenen Positionen und unbewusste Geschlechterstereotype reflektieren und ihre Handlungs- und Gestaltungsspielräume gendersensibel nutzen. Doch wie gestaltet sich das Spannungsfeld zwischen wahrgenommener Relevanz von Gleichstellung und der tatsächlichen Verantwortungsübernahme in der Hochschulkommunikation? Diese Frage soll in diesem Beitrag auf Grundlage der Ergebnisse des Projekts „Exzellenz entdecken und kommunizieren. Sensibilisierung und Kompetenzentwicklung zum Thema Exzellenz und Gender für Postdocs und Akteur*innen der Hochschulkommunikation“ (EXENKO) nachgegangen werden.
Economic Theory and Sharecropping in Early Modern France
Creators: name: Hoffman, Philip T.
Publisher: name: California Institute of Technology
Year: 1983

description: This paper uses a simple economic model of contract choice to explain the growth of sharecropping in sixteenth- and seventeenth century France--a topic that figures in much of the social and economic history of the period. The theory turns out to fit both qualitative and quantitative evidence, and although the results are as yet only preliminary, the theory does provide a better account of the spread of sharecropping than the explanations early modern historians have tended to rely upon.

Type species: Suberea creba Bergquist, 1995 (by Bergquist 1995, p. 41 as original designation, not examined).
Diagnosis (from Bergquist & Cook 2002a): Aplysinellidae with coarse irregular dendritic fibres in which bark and pith elements are present but pith predominates. The bark is strongly laminated and very brittle. Fibres can be very thick and render the texture of the sponge interior very rough to the touch. Dense collagen reinforces the matrix, making the sponges hard, to just compressible. The surface is smooth or conulose and the sponge form massive, sometimes stalked or branching.

New Evidence for an Old Controversy: Scattered Landholdings and Open Fields
Creators: name: Cull, Robert
name: Hoffman, Philip T.
name: Hughson, Eric
Publisher: name: California Institute of Technology
Year: 1992

description: We bring new evidence to bear on McCloskey's argument that farmers in the open fields reduced risk by scattering their land holdings. The new evidence is the grain output from a number of plots of land in two French villages, Onnaing and Quarouble, during the years 1701-1790. When combined with prices and wages, the output figures provide financial returns for each plot of land, and financial theory then allows us to construct land portfolios that minimize portfolio variance for a given mean return. The virtue of using returns (rather than simple output correlations) is that the returns take into account the price fluctuations farmers encountered. They also allow us to distinguish the benefits of scattering from those produced by crop diversification and they do so with greater accuracy than the output figures. In the end, the returns demonstrate that scattering of land holdings provided relatively little insurance. The real reduction in risk came not from scattering but from the diversification across crops inherent in the three-field system.

Exponential Discounting

description: We develop a behavioral axiomatic characterization of exponentially discounted utility (EDU) over consumption streams. Given is an individual agent's behavior in the market: assume a finite collection of purchases across periods. We show that such behavior satisfies a "revealed preference axiom" if and only if there exists a EDU model (a discount rate per period and a concave utility function over money) that accounts for the given intertemporal consumption.

description: We develop an axiomatic model that builds on Luce's (1959) model to incorporate a role for perception. We identify agents' "perception priorities" from their violations of Luce's axiom of independence from irrelevant alternatives. Using such perception priorities, we adjust choice probabilities to account for the effects of perception. Our axiomatization requires that the agents' adjusted random choice conforms to Luce's model. Our model can explain the attraction, compromise, and similarity effects, which are very well-documented behavioral phenomena in individual choice.

Strategic Uncertainty and Unraveling in Matching Markets
Creators: name: Echenique, Federico
name: Pereyra, Juan Sebastián
Publisher: name: California Institute of Technology
Year: 2013
Subjects: Two-sided matching
unraveling
strategic complementarity
assortative matching

description: We present a theoretical explanation of inefficient early matching in matching markets. Our explanation is based on strategic uncertainty and strategic unraveling. We identify a negative externality imposed on the rest of the market by agents who make early offers. As a consequence, an agent may make an early offer because she is concerned that others are making early offers. Yet other agents make early offers because they are concerned that others worry about early offers; and so on and so forth. The end result is that any given agent is more likely to make an early offer than a later offer.

Response Time and Utility
Creators: name: Echenique, Federico
name: Saito, Kota
Publisher: name: California Institute of Technology
Year: 2015
Subjects: Psychometrics, lag times, response times, revealed preference

description: Response time is the time an agent needs to make a decision.  One fundamental finding in psychology and neuroscience is that, in a binary choice, the response time is shorter as the difference between the utilities of the two options becomes larger.  We consider situations in which utilities are not observed, but rather inferred from revealed preferences: meaning they are inferred from subjects' choices.  Given data on subjects' choices, and the time to make those choices, we give conditions on the data that characterize the property that response time is decreasing in utility differences.

Average Choice
Creators: name: Ahn, David
name: Echenique, Federico
name: Saito, Kota
Publisher: name: California Institute of Technology
Year: 2015
Subjects: Stochastic Choice, Logit Model, Luce Model, Path independence, Average choice

description: This is an investigation of stochastic choice when only the average of the choices is observable. For example when one observes aggregate sales numbers from a store, but not the frequency with which each item was purchased. The focus of our work is on the Luce model, also known as the Logit model. We show that a simple path independence property of average choice uniquely characterizes the Luce model. We also characterize the linear Luce mode, using similar tools. A linear version of the Luce model is used most frequently in empirical work by applied economists.

Our characterization is based on the property of path independence, which runs counter to early impossibility results on path independent choice. From an empirical perspective, our results provide a small-sample advantage over the tests of Luce's model that rely on estimating choice frequencies.

The Core Matchings of Markets with Transfers
Creators: name: Chambers, Christopher P.
name: Echenique, Federico
Publisher: name: California Institute of Technology
Year: 2008
Subjects: Matching, Testable Implications, Coalition Formation

description: We characterize the structure of the set of core matchings of an assignment game (a two-sided market with transfers). Such a set satisfies a property we call consistency. Consistency of a set of matchings states that, for any matching v, if, for each agent i there exists a matching μ in the set for which μ(i) = v(i), then v is in the set. A set of matchings satisfies consistency if and only if there is an assignment game for which all elements of the set maximize the surplus. We also identify conditions under which we can assume the assignment game has nonnegative values.
