The problem of negatives in input-output analysis: a review of the solutions
No full textThe main models to construct technical coefficients are the industry technology model and the commodity technology model. The former yields nonnegative coefficients and the latter fulfills nice theoretical properties, such as price invariance. Although the models are very different, this paper presents a flexible formula that encompasses both of them. Various solutions to the problem of negatives of the commodity technology model-including replacements by industry technology based coefficients-are reviewed in our framework.Input-output analysis; technical coefficients; use and make matrices
Pollution control in a decentralized economy : which level of government should subsidize what in Brazil
No full textSubsidies in Brazil essentially serve three purposes: (i) if assigned to the right level of government, they could reinforce the effectiveness of pollution taxes in reducing pollution; (ii) they offer an opportunity foradditional combinations of instruments and hence more flexibility in dealing with specific institutional characteristics of every state; and (iii) they can serve a purely"public relations"affect by showing that the federal government does not always rely on"sticks"but can also provide"carrots."The authors have four main messages of relevance to the Brazilian economy. First, carrots will not work without a stick. Subsidies of any type will not work without a coexisting pollution tax. Second, some carrots are better than others at achieving the government's objectives. In general, a state abatement subsidy is the more effective instrument to combine with a pollution tax. But when federal or state inspection capabilities are limited, monitoring subsidies may be an effective substitute. Third, increasing abatement subsidy rates can be counterproductive - tending to increase firm investment more than necessary and hence reduce the pollution tax base, while increasing subsidy costs. This can worsen the monitoring and inspection efforts and fiscal revenue. Finally, it is more effective to keep subsidy rates low if they are to be effective and sustainable and at the same time get the endorsement needed from state and federal fiscal administrations.Environmental Economics&Policies,Water and Industry,Pollution Management&Control,Public Sector Economics&Finance,Taxation&Subsidies
Atopsyche (Atopsaura) yunguensis Rueda & Martin, 2006, new species

The new species is in the <i>falina</i> group (Ross & King 1952). <i>A. yunguensis</i> differs from other species in the shape of parapods which are large, broadened at the tip and dorsally curved toward the midline; the apical segment of the inferior appendages, which are curved toward the midline; and the dorsal lobe of the phallotheca, which is bilobed and curved anteriorly.</p> <p>Larva. Length 14-17 mm. Head (Figs. 1 A, 1B) yellowish, with dark brown dorsal and ventral area extending laterally in vertical narrow band, with yellowish muscle scars in constant, apparently species specific pattern; dorsally, dark brown area extends anteriorly, to frontoclypeal sutures. Pronotum (Fig. 1 C) ocher, with black anterolateral external margins bearing short oblique black bar; center of pronotum with colored brown area with pale spots; posterior margin irregular and black. Mesal sclerite of prosternum (Fig. 1 D) with posterior margin black; 2 smaller anterolateral sclerites with internal margins rounded, bearing posterior long process and short lateral external process.

Colouration of head and thorax light reddish brown, setal warts and abdomen stramineous. Forewing yellowish, with an oval pale macula parallel to the costal margin (pterostigma), and light brown stripes over transversal veins. The colouration of the body and wings was observed in specimens preserved in alcohol.</p> <p>Diameter of eye, in dorsal view, 2.3 times the length of the interocular distance. Anterolateral process of sternum V 1.5 times the length of the sternum.</p> <p> <i>Genitalia.</i> Segment IX with anterolateral margin rounded (Figure 4A). Tergum X, in dorsal view, deeply divided mesally, internal margin of each hemitergite concave with apex slightly curved to the midline bearing a small fold preapically (Figure 4B); in lateral view with ventral margin almost straight, apex pointed (Figure 4A). Inferior appendages two-segmented, setose; basal portion long (2.5 times the length of the apical segment), narrow basally, broad at apex (Figure 4A,C). Phallus long, tubular; basal portion broad, forming an angle of about 90 ◦ with the distal part (Figure 4D,E); distal portion with apex produced dorsally, bifid in dorsal view (Figure 4D); ventroapical area of phallus membranous when the endophallus is invaginated (Figure 4E). Endophallus membranous, tubular, truncated at apex, without spines or processes; when evaginated the tip can be seen through the dorsal process of the phallus as an oval membranous structure, because of the transversal wrinkles that cover its surface. Internal sclerite long and slender, in lateral view slightly curved in the apex (Figure 4E).</p> <p> <i>Female.</i> Unknown.</p> <p> <i>Systematic considerations</i></p> <p> This species is related to <i>S</i>. (<i>R.</i>) <i>elisae</i> sp. nov. Both species share the bifid dorsoapical area of phallus. The <i>S</i>. (<i>R</i>.) <i>valeni</i> is distinguished from other species by the tip of</p> <p>phallus. The bifid apex and the membranous tubular endophallus truncated at apex are the main characters for the identification of this species.</p> <p> <i>Etymology</i></p> <p> This species is dedicated to Valentino, son of one of the authors (JVS). The name <i>valeni</i> is derived from his nickname, “Valen”.</p>Published as part of <i>Rueda Martín, Paola A. & Sganga, Julieta V., 2011, Smicridea McLachlan (Trichoptera: Hydropsychidae) from northwestern Argentina and Bolivia: new species, redescription, association and new records, pp. 2215-2230 in Journal of Natural History 45 (35 - 36)</i> on pages 2223-2225, DOI: 10.1080/00222933.2011.590947, <a href="http://zenodo.org/record/5204287">http://zenodo.org/record/5204287</a>
