红色系石榴石的选购及保养

石榴石的产地石榴石的矿床有很多种,原生矿床主要有岩浆岩或变质岩,原生矿床的石榴石产量较大,但品质好的不多,大多数有不同程度的裂隙或微裂隙。次生矿床主要以冲击矿床为主,由于经过自然搬运和筛选,具有严重裂隙的石榴石已经几乎被撞击碎裂,剩下的都是少数品质较高的石榴石,故于次生矿床的石榴石中,品质相对较高的石榴石相对较多。经流水搬运的次生矿几乎为鹅卵石状,已经无法看到其原始的晶体形态。

Sustainable development and financial institutions: Do banks' environmental policies influence customer deposits?

This paper investigates the relationship between the environmental policies taken by financial institutions and the choice of depositors on where to save their money. Prior research has shown that increases in the number of customers making deposits are driven by bank pricing policy and switching costs for depositors. By employing a dynamic panel data model, this study empirically tests how environmental performance influences the depositors' choice on where to put their money in a sample of worldwide financial institutions from 2011 to 2018. The main results suggest that there is a negative relationship between banks' environmental performance and customers' deposits. Furthermore, the banks that are the best at managing carbon emissions and at pursuing sustainable development pay lower interest rates on customer deposits.     

The effect of raising deposit insurance coverage in times of financial crisis – Evidence from Croatian microdata

Typically, depositors in transition countries react very sensitively to the safety of deposits. Faced with rising deposit outflows in October 2008, many transition countries were forced to extend the limits of deposit insurance coverage. Has this calmed private agents? Or has it caused more uncertainty? We analyze these questions by employing household survey data for Croatia from exactly the time deposit insurance was extended. First, we provide evidence how the financial crisis has affected trust in banks and trust in the local currency. Then, we show that the increase in deposit insurance coverage had an immediate and positive impact on how people perceived the safety of deposits and the credibility of the local currency. Therefore, our results suggest that this policy measure helped to prevent a more serious and dangerous meltdown of deposits and a further shift towards foreign currency denominated assets. However, despite this effect the perceived safety of deposits remained lower than it was before the financial crisis. We also consider this finding to be of relevance for other countries of Central, Eastern and Southeastern Europe.     

What do bank acquirers value in non-public bank mergers and acquisitions?

This study investigates what target, market, and acquirer characteristics influence book value multiples in 288 non-public bank acquisitions from 2001 Q3 to 2005 Q4. Multiples rise with acquirer size and capital ratios. Targets with high proportions of industry-adjusted core and large deposits have higher multiples. When using target variables relative to acquirers, multiples rise with higher proportions of core and large deposits, larger average bank size in the market, and relative growth in assets, loans, and deposits as well as market growth. In contrast to prior findings for public targets, acquirers do not pay premiums for target accounting performance.

Risk pricing of wholesale funds and the behavior of retail deposit rates

We explore the relationship between bank risk and retail deposits. Predicted risk premiums on wholesale funds explain retail rate heterogeneity through two channels. First, increased bank risk premiums encourage the bank to substitute from wholesale funds to small certificates of deposits (CD) by increasing small CD rates. Second, increased rival risk premiums in a local market require the bank to increase small CD rates even more. Our results are consistent with risk encouraging the use of small CDs as a marginal source of funds and promoting local market competition for small CDs. As risk premiums rise, banks also reduce rates on other retail deposits. Our approach has implications for regulatory and monetary policies and financial stability.
