Expected and Predicted Realignments: The FF/DM Exchange Rate During the EMS
No full textAn empirical model of time-varying realignment risk in an exchange rate target zone is developed. Expected rates of devaluation are estimated as the difference between interest race differentials and estimated expected rates of depreciation within the exchange rate band, using French Franc/Deutsche Mark data during the European Monetary System. The behavior of estimated expected rates of depreciation accord well with the theoretical model of Bertola-Svensson (1990) . We are also able to predict actual realignments with some success.
Carbonea tephromelae M. Svensson & M. Westb. 2021, sp. nov.
No full textCarbonea tephromelae M.Svensson & M.Westb. sp. nov. Fig. 2A–2E MycoBank No: MB840305 Holotype:— SWEDEN. Lule lappmark: Jokkmokk par., Padjelanta National Park, 11 km WNW of Staloluokta, S slope of Unna Duvgge (Unna Toki), c. 460 m NE of small cabin, 67.34787˚N, 16.45453˚E, elev. 703 m, S-exposed slope in bare mountain region, on Tephromela atra on rock, 5 August 2020, Martin Westberg PAD384 (UPS L-994014). Diagnosis:—Distinguished from other Carbonea species with a colourless hypothecium by having globose to broadly ellipsoid spores and by growing on Tephromela atra. Etymology:—Named after its host species Tephromela atra (Huds.) Hafellner. Description:—Lichenicolous fungus. Thallus inapparent, inhabiting the thallus of Tephromela atra, which darkens and is apparently damaged due to the infection (Fig 2A). Apothecia black, shining, c. 0.2–0.4(–0.5) mm diam., rounded to flexuose, sessile on the thallus of the host. Disc flat or becoming somewhat convex in larger apothecia. Proper exciple concolorous with the disc, persistent, narrow, raised or level with the disc in older apothecia. Apothecial anatomy: Proper exciple opaque, appearing black even in thin sections, densely pigmented blue-green (Cinereorufa-green sensu Meyer & Printzen 2000) in the upper part, in the lower part beneath the hypothecium in mixture with a dark brown pigment, c. 20–45(–85) µm thick, composed of radiating, thick-walled hyphae with c. 2 µm wide lumina. Hymenium colourless or faintly blue-green, c. 50–75 µm tall. Epihymenium strongly blue-green (Cinereorufa-green), N+ red, K−. Hypothecium colourless, without visible crystals in polarized light. Paraphyses simple or forked near the tips, septate and often slightly constricted at the septa, c. 1.5 µm in midhymenium, tips colourless, cylindrical to clavate, 1.5–2.5 µm wide. Asci of Lecanora - type, 8-spored, clavate, 41–49 × 12–19 µm. Ascospores broadly ellipsoid to globose, (7.5–)8.66 ±0.97(–11) × (5.5–)6.81 ±0.71(–8.5) µm; l/b ratio (1–)1.28 ±0.2(– 1.67) (n=57). Distribution and habitat:—The species is so far known from two localities in northern Sweden. Its host Tephromela atra, however, is a common and widespread lichen on both calcareous and non-calcareous rocks. We searched for Carbonea tephromelae in 264 collections of T. atra sensu lato in herb. UPS, of which 183 were from Europe, 29 from North America, 22 from Oceania, 14 from Asia, 12 from South America and 4 from Africa, without finding any additional specimens. Most of the examined collections were from lowland localities, and it is possible that C. tephromelae is restricted to or at least more common in alpine to subalpine localities. Additional specimens examined: — SWEDEN.

Brianaria (Psoraceae), a new genus to accommodate the Micarea sylvicola group
No full textThe new genus Brianaria S. Ekman & M. Svensson is introduced for the Micarea sylvicola group, with the new combinations Brianaria bauschiana (Korb.) S. Ekman & M. Svensson, B. lutulata (Nyl.) S. Ekman & M. Svensson, B. sylvicola (Flot. ex Korb.) S. Ekman & M. Svensson and B. tuberculata (Sommerf.) S. Ekman & M. Svensson. The new genus is characterized by a chlorococcoid, non-micareoid photobiont, small, convex apothecia without an excipulum, an ascus of the 'Psora-type', 0-1-septate ascospores, dimorphic paraphyses, and immersed pycnidia containing bacilliform conidia. Brianaria is shown to form a monophyletic group in the Psoraceae, where it is probably the sister group to Psora and Protoblastenia

Targeting vs. Instrument Rules for Monetary Policy
No full textSvensson (JEL, 2003) argues strongly that specific targeting rules first order optimality conditions for a specific objective function and model are normatively superior to instrument rules for the conduct of monetary policy. That argument is based largely upon four main objections to the latter plus a claim concerning the relative interest-instrument variability entailed by the two approaches. The present paper considers the four objections in turn, and advances arguments that contradict all of them. Then in the paper's analytical sections, it is demonstrated that the variability claim is incorrect, for a neo-canonical model and also for a variant with one-period-ahead plans used by Svensson, providing that the same decision-making errors are relevant under the two alternative approaches. Arguments relating to general targeting rules and actual central bank practice are also included.
