Labor flows are important channels for knowledge spillovers between firms; yet competing arguments provide different explanations for this mechanism. Firstly, productivity differences between the source and recipient firms have been found to drive these spillovers; secondly, previous evidence suggests that labor flows from multinational enterprises provide productivity gains for firms; and thirdly, industry relatedness across firms have been found important, because industry-specific skills have an impact on organizational learning and production. In this paper, we aim to disentangle the effects of productivity gap, multinational experience and industry relatedness in a common framework. Hungarian employee–employer linked panel data from 2003–2011 imply that the incoming labor from more productive firms is associated with increasing future productivity. The impact of multinational spillovers cannot be confirmed, once productivity differences between the firms are taken into account. Furthermore, we find that flows from related industries outperform the effect of flows from same and unrelated industries even if we control for the effects of productivity gap and multinational spillovers.

Part 1 of the book discusses the geology of the Gemericum, its metallogenic evolution during the Variscan and Alpine epochs, and the main types of mineralisation. Part 2 describes the ore deposits in detail. Magmatogenic mineralisation includes hydrothermal-greisen and albitic Sn-W and REE deposits and a plutonic-hydrothermal stockwork Mo-W deposit. Metamorphic-hydrothermal veins include 18 areas of siderite-sulphide mineralisation, some of them important orefields for Fe, Cu and other base metals, and several antimonite vein systems. Stratiform deposits include sedex deposits of base metals, Fe oxides, Mn, U and Cu and hydrothermal-metasomatic deposits of siderite, ankerite, magnesite and talc. There are bauxite and red clay residual deposits, weathered crusts on ultrabasic complexes and Sn and Au placers. Part 3 is on non-metallic deposits: magmatic feldspar and building materials, hydrothermal quartz, barite, specularite and asbestos, and sedimentary gypsum, anhydrite, carbonates and other rocks. Part 4 is on precious and decorative stones. There are 67 pages of references, a geographical index and a deposits index., Part 1 of the book discusses the geology of the Gemericum, its metallogenic evolution during the Variscan and Alpine epochs, and the main types of mineralisation.
