Replication data for "Endogeneity and non-response bias in treatment evaluation - nonparametric identification of causal effects by instruments"
No full textReplication data for Hans Fricke, Markus Frölich, Martin Huber, and Michael Lechner (2020): "Endogeneity and non-response bias in treatment evaluation - nonparametric identification of causal effects by instruments", Journal of Applied Econometrics, forthcoming. "expdata.RData" contains the data in R format. "attrition late public use code.R" contains the R code for replicating the empirical results in Table 6 of the paper. The aim is to evaluate the causal effect of a treatment (university gym visits) on an outcome (self-assessed health of students) in the presence of both treatment endogeneity and attrition/non-response bias, based on two distinct instrumental variables for the treatment (randomized cash incentive to visit the gym) and response (cash lottery for participating in the follow-up survey)

Thecodonta rainesi Raines & Huber 2012, sp. nov.
No full text<i>Thecodonta rainesi</i> Huber <i>in</i> Raines & Huber sp. nov. <p>Figures 31 A–G</p> <p> <b>Type Material.</b> Holotype: LACM 3201, single LV, 3.7 mm. Paratype 1: LACM 3202, single RV, 3.2 mm, from type locality. Paratype 2: LACM 3203, single LV, 3.6 mm, from <i>EI</i>, Mataveri Bay, 50 m. Paratypes 3–4: Coll. MHU, 2 single valves, from <i>EI</i>, Hanga Roa, 50 m. Paratypes 5–6: Coll. BR, 2 single valves, from type locality.</p> <p> <b>Type Locality.</b> Dredged at 30–50 m in fine sand, off the western coastline near Tahai, Easter Island, 27°07’20” S, 109°26’30” W.</p> <p> <b>Description.</b> A small, whitish <i>Thecodonta</i> species, ovate, smooth, with low and strongly prosogyrate umbones. Shell small, not exceeding 3.7 mm; ovate, gently rounded posteriorly and anteriorly; equivalve, strongly inequilateral; rather compressed; thin; white, showing spots and blotches in the substance of shell which lend to it a watered silk effect. The umbones are low and strongly prosogyrate and are situated near the anterior end. Prodissoconch, P1 typically eroded, possibly D-shaped, ca. 130 µm length by 85 µm height, P2 ovate with slender growth lines, white to tan in color, ca. 430 µm length by 369 µm height. In adult valves the dorsal line curves gently from the umbo to the posterior end. The surface is nearly smooth, marked by weak commarginal growth stops only. The elongate lateral dorsal tooth, stronger expressed in the receiving LV is marginally placed. The shorter anterior laterals are equally marginally placed. The single cardinal tubercles in either valve rest at the upper margin of the anterior lateral. The laterals are smooth not serrated. The posterior scar is narrow, elongate, rather small and marginally placed; the posterior scar is suborbicular, also small and marginally placed. The connecting, continuous pallial line is very weakly impressed, but comparatively broad and patchily interrupted. The margins are smooth.</p> <p> <b>Comparative diagnosis.</b> The very inequilateral-ovate shape and thin structure, together with a continuous pallial line, characteristic dentition, and minute size closely resembles the small <i>Thecodonta</i> -group.</p> <p> In umbonal position Bernard’s (1983: 68) prosogyrate view for thecodontinids is still applied. Prosogyrate beaks were also diagnosed by Chavan <i>in</i> Moore (1969: N532) for <i>Thecodonta</i>. However, Dall, Bartsch and Rehder (1938: 148) noted the reverse montacutinid opisthogyrate position. The as yet unknown anatomy of <i>Thecodonta</i> will be needed to decide once and for all.</p> <p> Japanese authors synonymized Dall, Bartsch & Rehder, 1938 ’s genus <i>Kona</i> with <i>Thecodonta</i> and recognized only the type species as valid from Japan (e.g. Higo <i>et al</i>., 1999: N732). Possible syntypes of smaller and larger Japanese specimens are illustrated in Higo <i>et al</i>. (2001 B732 and B732s). Severns (2011: 470, pl. 215 fig. 6) recognized only <i>Thecodonta symmetrica</i> Pilsbry, 1921, as valid from the Hawaiian Islands, and consequently <i>Kona bucki</i> Dall, Bartsch & Rehder, 1938 as a synonym. Both views are shared.</p> <p> Moreover, due to a similar morphology, the nearly identical shape changes during growth and similar maximum sizes 4.7 mm (<i>T. sieboldi</i>) and 4 mm (<i>T. symmetrica</i>) synonymy cannot be completely excluded, because genetic data may one day reveal these two as conspecific. Most distinct at present are their habitats, i.e. subtidal 2– 10 m (<i>T. symmetrica</i>) and sublittoral 50–100 m (<i>T. sieboldi</i>).</p> <p> The respective data of <i>T. rainesi</i> is within 30– 50 m. There is no commensal mode of life data recorded for either the Japanese or Hawaiian species of <i>Thecodonta</i>. Severns (2011) noted the habitat as silty sand, inshore of the reef, Japanese authors recorded sandy and muddy bottoms, while <i>T. rainesi</i> is found on fine sandy bottoms.</p> <p> Morphologically, <i>T. rainesi</i> differs significantly in shape from its two congeners. Equal sized <i>T. sieboldi</i> and <i>T. symmetrica</i> are shorter and oblique in shape. Larger congeners approach <i>T. rainesi</i> somewhat more, but still have a stronger curved ventral margin and stronger developed teeth. The nearly smooth sculpture with watery blotches is similar to Japanese specimens, whereas all Hawaiian specimens seen are rather dull.</p> <p> <b>Remarks.</b> At first this species was misidentified by the junior author. However, the senior author observed differences which finally led to a new description by the junior author.</p> <p> <b>Habitat.</b> Occasionally found at several locations around <i>EI</i>, dead in sand, from 30–50 m.</p> <p> <b>Distribution.</b> At present <i>Thecodonta rainesi</i> is only known from Easter Island— <b>E1.</b></p> <p> <b>Etymology.</b> This new species honors Bret Raines’ relentless efforts during many years of his life for a better understanding of the bivalve fauna of Rapa Nui.</p>Published as part of <i>Raines, Bret & Huber, Markus, 2012, 3217, pp. 1-106 in Zootaxa 3217</i> on pages 61-6
Tellimya tahaia Raines & Huber 2012, sp. nov.
No full textTellimya tahaia sp. nov. Figures 30 A–F Type Material. Holotype: LACM 3161, 1 single RV, 6.9 mm. Paratypes 1–2: LACM 3162, 1 single RV, 6.8 mm and 1 single LV, 5.5 mm Motu Iti, Easter Island, dredged in 65 m. Type Locality. Dredged at 30–50 m in fine sand, off the western coastline near Tahai, Easter Island, 27°07’20” S, 109°26’30” W. Mode of life and host are unknown. Description. An ovate, comparatively large Tellimya species fragile in structure with rounded posterior margin. Shell small, below 7 mm, ovate, narrower and shorter posteriorly, equivalve, inequilateral with umbones closer to the rounded posterior end; thin; umbones rounded, broad, orthogyrate. Prodissoconch, P1 small, but typically worn away, P2 ovate, boundary ill defined, faint commarginal lines nearly obsolete, ca. 317 µm length by 220 µm height. Nepioconch with weakly raised radial lines. Adult shell white internally and externally with irregular opaque blotches; weakly inflated, non-gaping, surface superficially smooth. Hinge simple; in both valves with a strong anterior lateral, directed ventrally. Behind this front tooth follows a deep resilial recess. Its posterior end is followed by an oblique, characteristic, tooth-like ridge. Pallial line continuous and comparatively broad; muscle scars unequal, the narrowly shaped anterior scar is significantly larger; the posterior scar is rounded-ovate. Ligament internal and subumbonal. Margins smooth, very fragile. Comparative diagnosis. Comparable to the new species is T. pauciradiata also from EI. Both share a very similar dentition. However, the posterodorsal margin of T. tahaia is evenly rounded, not bulged as in T. pauciradiata and in the type species T. ferruginosa. The shape of T. tahaia is higher and significantly shorter. Consequently, the umbones are broader and more pronounced. Tellimya tahaia is not known to reach the large size of T. pauciradiata. Whereas T. pauciradiata is commonly encountered, T. tahaia has only been rarely found. The three New Zealand species are significantly distinct in shape. Moreover, T. benthicola and T. reinga have an anterior lateral which is less pronounced and they live in deeper water. Remarks. There is nothing similar known from the Hawaiian or Marquesas Islands. Distribution. Tellimya tahaia is rather rare and only known from the type locality and Motu Iti— E1. Etymology. The name reflects the type locality.Published as part of Raines, Bret & Huber, Markus, 2012, 3217, pp. 1-106 in Zootaxa 3217 on pages 59-6

Umbones elevated. Posterior end obliquely truncate with a narrow ridge from the umbo to the ventral margin; anterior end well rounded. Exterior surface of uniform commarginal ridges. Interior smooth with pallial sinus running from muscle to muscle. Hinge stout, consisting of divergent cardinals and long laterals on the posterior and anterior. Color variable, creamy white to pale yellow background with irregularly spaced red to reddish orange radial rays.</p> <p> <b>Remarks.</b> The pallial sinus of the <i>EI</i> specimens runs from muscle to muscle, thus, juvenile <i>Tellinella staurella</i> (Lamarck, 1818), and <i>Tellinella virgata</i> (Linnaeus, 1758), are excluded. Lamprell and Whitehead (1992) placed <i>P. radians</i> in <i>Tellinella</i> Mörch, 1853, but that does not fit the shape or pallial sinus, and <i>Tellinella</i> is generally more elongate and much larger in size. However, the genus <i>Pristipagia</i> which is related to <i>Serratina</i> Pallary, 1922, does match. This opinion was confirmed by A. Langleit, (pers. comm., 2010).</p> <p> The type is illustrated in Higo <i>et al</i>. (2001: B912). Originally described without location, <i>Pristipagia radians</i> has been recorded from Australia to Japan and also from the Kermadec Islands. The type specimen is moderately larger (21 mm) and higher in shape than the <i>EI</i> material. However, the same shape variability of <i>P. radians</i> was also seen in <i>Pristipagia adamsii</i> (Bertin, 1878), of the Red Sea.</p> <p> <b>Habitat.</b> Occasionally found at several locations around <i>EI</i>, in sand and rubble, from 10–150 m. Live taken at 30 m.</p> <p> <b>Distribution.</b> <i>Pristipagia radians</i> is known from Australia to Japan, including the Kermadec Islands, but not the Hawaiian Islands.

Shell moderately small, not exceeding 13 mm, elongate-ovate, posteriorly with a weak flexure and obscurely rostrate; rather thin; white with 5–6 broad orange-red radial streaks, emanating from the umbones; internal posteriorly and in the nymphal area rose red in some, otherwise white; no lunule; umbones very low, small, opisthogyrate, situated at the posterior third of the valve. Prodissoconch round, moderately elevated, P1 somewhat pitted, ca. 118 µm length by 93 µm height, P2 with faint to weak commarginal lines, ca. 228 µm length by 185 µm height. Adult valves compressed. Sculpture of dense, regular, commarginal threads. Hinge line rather thin, in RV with a strong, bifid posterior and a weak anterior cardinal, a short, strong anterior lateral and a nymphal posterior lateral. LV with a single strong bifid cardinal, laterals thin and vanishing. Pallial sinus very deep, ventrally surpassing anterior adductor scar, confluent; both muscle scars are comparatively large. External ligament rather short and strong, resting on a nymph, yellowish-brown. Margins smooth.</p> <p> <b>Comparative diagnosis.</b> With regard to placement of this new species, the commarginal sculpture and lateral dentition exclude <i>Loxoglypta</i> Dall, Bartsch & Rehder, 1938, and the finer sculpture and lateral dentition exclude <i>Nitidotellina</i> Scarlato, 1965, as well. The hinge with a pronounced anterior lateral in the RV, vanishing laterals in the LV and the deep, confluent pallial sinus, together with shape, size and sculpture match the European type species of <i>Moerella</i> quite well. This assessment was shared by A. Langleit, (pers. comm., 2010). None of the illustrated <i>Moerella</i> species from Australia, New Zealand or Japan are particularly close.</p> <p> <b>Remarks.</b> There is nothing similar known from the Hawaiian Islands.</p> <p> <b>Distribution.</b> <i>Moerella laperousea</i> is commonly found from 30–200 m in fine sand, at various Easter Island locations, notably off the western coastline near Tahai— <b>E1</b>.</p> <p> <b>Etymology.</b> The name reflects the type locality.</p>Published as part of <i>Raines, Bret & Huber, Markus, 2012, 3217, pp. 1-106 in Zootaxa 3217</i> on pages 76-7

Paratypes 1–3: LACM 3149, 3 single valves, 2.3–3.9 mm.</p> <p> <b>Type Locality.</b> Along the base of cliffs in sand and rubble at 20 m off Punta Rosalia, east side of Anakena, Easter Island, 27 o 04’18” S, 109 o 19’45” W.</p> <p> <b>Description.</b> A small, semi-translucent white <i>Nuculana</i> species, with raised subcentral umbones. Shell small (up to 4 mm in length), not very fragile, subtriangular, only slightly inflated, equivalve. Umbones raised, nearly centrally located. Prodissoconch, P1 round, smooth, boundary often weakly defined, ca. 247 µm length by 186 µm height, P2 not present. Anterior and posterior margins of adult valves subequal, with posterior margin shorter. Exterior surface smooth with commarginal growth lines, increasing in strength towards ventral margin. No posterior sulcus. Interior non-nacreous, lacks deep pallial sinus. Hinge line highly arched, consisting of split dentition with central resilifer; anterior with 7–9 teeth, posterior with 4–6 teeth. Color white.</p> <p> <b>Comparative diagnosis.</b> A non-nacreous interior together with the shape excludes the genus <i>Ennucula</i> (= <i>Leionucula</i> auctt.). The shape, lack of a deep pallial sinus, and solid structure excludes the genera <i>Yoldiella</i> Verrill & Bush, 1897, and <i>Scissileda</i> Kilburn, 1994. The presence of a resilifer rules out all malletiids including <i>Neilonella</i> Dall, 1881. The lack of a sulcus combined with a rather shallow depth rules out the genus <i>Ledella</i> Verrill & Bush, 1897. The lack of a very thin hinge with few weak teeth and distinct shape exclude all Sareptidae Stoliczka, 1870.</p> <p> <b>Remarks.</b> Although the shape and weak commarginal sculpture do not match typical <i>Jupiteria</i> very well, the closest species appears to be <i>Nuculana</i> (<i>Jupiteria</i>) <i>manawatawhia</i> Powell, 1937, from New Zealand. More and better material is needed to determine, if a new genus is warranted.</p> <p> <b>Distribution.</b> <i>Nuculana</i> (s.l.) <i>anakena</i> is occasionally found at several locations around <i>EI</i>, in sand or rubble, from 10–100 m — <b>E1</b>.</p> <p> <b>Etymology.</b> Named after the type locality.</p>Published as part of <i>Raines, Bret & Huber, Markus, 2012, 3217, pp. 1-106 in Zootaxa 3217</i> on page 1
